Breaker Trips When I Turn The Light On – How To Troubleshoot

Breaker trips from light switch. I turn the kitchen ceiling light switch ON and the circuit breaker trips . I am assuming the light switch or the light fixture is the cause. What can cause the breaker to trip when the light switch is turned on?

There are different reasons why a breaker will trip/reset when you turn on a light using a wall switch. See below for the reasons why flipping on a light switch could cause a breaker to trip/flip/reset.

SAFETY: Be sure to flip the breaker off when inspecting or troubleshooting any electrical issue. Use a flashlight or headlamp to safely inspect the area. Use the appropriate tools/gloves when working with electrical components. It is recommended to read this complete page before you begin troubleshooting your electrical issue.

Quick Troubleshooting: Start by turning the breaker OFF. Check the light switch by removing the switch cover. Fix any wires that are loose or damaged. Check the light fixture for any brittle/damaged or loose wires. If both the light switch and light fixture are wired properly, next inspect the wiring within the circuit. Most “breaker tripping” issues in this case involve the light switch and or the light fixture. For more detailed information keep reading below…

Recently replaced the light switch or fixture? If you have replaced the light switch or light fixture with a new one and the breaker trips when you turn the light on, the switch or fixture is most likely wired incorrectly. Turn off the circuit breaker and rewire the switch or fixture. Use the wiring diagram that came with the light switch/fixture to wire it correctly.

Having electrical issues with your ceiling fan? Ceiling fans may vibrate connections loose and cause a tripping breaker.

What do I check to fix the breaker from tripping? To find out why the breaker trips when you turn the light on, check the wiring, the light fixture, and the light switch. Inspect all components to be sure the wiring on the light fixture and light switch are not loose or damaged. Check the switch and fixture for the correct wiring with no shorts to neutral/ground. All of these conditions can cause the breaker to trip.

How To Fix Light Switch/Trips Breaker

Troubleshoot efficiently by checking the switch first. Remove the switch plate (2 screws) and check the switch with a flashlight. Inspect for any wiring touching the side of the box or other wires. Fix as needed, then check the light fixture and inspect the wiring for issues. If the issue goes beyond the light switch and light fixture, call an electrician to troubleshoot the problem.

When a light switch trips the breaker, a faulty light switch or light fixture is usually the cause. A wire may have come loose at the switch or fixture and is shorting out the hot wire. Always check the switch and fixture first.

Also check any GFCI receptacles that are on the circuit for a malfunction or fault.

If you recently hung a picture or put a nail/screw through the wall, this is likely your issue as a nail or drill bit may have damaged the wiring. If a nail or screw has damaged the wire, you can replace the wiring around the fault by using junction boxes for the splice.

Why Does Light Switch Trip Breaker?

See below for the reasons why a breaker can trip and what may be causing the problem. There can be more reasons but these are the most common/average.

Light Switch Can Trip Breaker When:

• Light Fixture Fault
• Light Switch Is Faulty
• Wire Connections Are Loose
• Short Circuit Issues
• Ground Fault Problems
• Nail/Screw Through Wiring
• Rodent Chewed/Damaged Wires
• Faulty GFCI Receptacle

Reasons Light Switch Trips Breaker

1. Light Fixture Fault If a light fixture is faulty, a breaker can become overloaded. The wires in an old light fixture can fall apart and cause a short or ground out. Turn off power before checking the light fixture for damage. Replace the light fixture if found to be faulty.

2. Light Switch Is Faulty A light switch that has become faulty can short out and trip a breaker. An old light switch can crack and become unusable and cause the breaker the flip. The wires can become brittle and cause a circuit overload or a short. Turn off the breaker when checking the light switch. Replace the light switch if found to be faulty.

3. Wire Connections Are Loose If any of the wires become loose it can ground out and short circuit causing the breaker to trip/reset. Remove power, remove cover if applicable, and inspect the terminal screws on the switch to be sure they are not loose. If loose, tighten the screws and be sure they are secure. Be sure terminal screws are tightened all the way down.

4. Short Circuits A wire is contacting another wire and current flows through and flips the breaker. Wires can become brittle and the insulation can fall off. Inspect all wires to be sure there are no short circuits. Replace any wiring if you find it to be brittle and or the insulation has become brittle and falling off. This causes grounding and shorts.

5. Ground Faults This happens when a live wire comes in contact with a metal area of the switch housing or similar. This can cause shock and also trip the breaker. Inspect all areas on the wiring to be sure there are no ground faults.

6. Nail/Screw Through Wiring If you have drilled into the wall to hang a picture lately, you may have drilled too deep and damaged a wire. This is a difficult scenario as the damaged wire will need to be repair and or replaced. It is best to call a pro at this point.

7. Rodent Chewed/Damaged Wires A rodent in the wall may have chewed on the wiring. This will cause damaged wiring and cause a short that will flip the breaker. The wiring will need to be repaired or replaced.

8. Faulty GFCI Receptacle Check any GFCI receptacles on the circuit for a malfunction. If the light switch wiring is going through a GFCI receptacle and the GFCI is faulty, this can cause a problem and trip the breaker. Replace the GFCI receptacle if found to be faulty.

8 thoughts on “Breaker Trips When I Turn The Light On – How To Troubleshoot”

I just recently moved into a old family rental house and in the kitchen there is a ceiling fan light combo and a block off plate for the switch meaning no switch. Well I got tired of having to pull the cord while walking slowly to try and not trip in the dark. I pulled the cover off the wall and have old 2 wire 1 yellow or white and 1 black both capped off. So I thought easy enough and hooked a switch up to it not thinking. The light and fan have power so putting a switch here will do nothing. Well acted without using common sense and installed a switch, when the switch is off lights and fan working as they were before, when I flip the switch on it throws a breaker and the light and fan turn off. So I took the fixture down and it’s wired White wire to white wire green capped black to black and in the same wire nut black to blue there is 4 different wire strands coming into the ceiling box all 2 wire – black and white all besides 1 set are wired together and then to the fixture. Another reason I’m putting in a switch is because we’re thinking about moving the fan and light to the living room and putting a standard light fixture, we can’t do that if theirs no switch it stays on constantly.

I have 6 spotlights in my kitchen ceiling , when they are turned on after some time the breaker will trip , tried installing new spotlights and it still tripping , any suggestions please

My lightswitch has 3 sets of wires coming into it, live feed from the box, run to the light, and continued circuit through to the outlets. I wired a piggy tail from the live feed to the switch and connected the light run and outlet run together with a piggytail. All whites are capped and all grounds are capped. I have to power to my light switch but no power to my outlets. When I flip the switch it shorts out the AFCI Breaker. I then checked to see if it is the light and so I hard wired the light to the live feed from the breaker panel and the light stays on while the switch is off but I still have no power to my outlets. We ran the wire and it all testes great, only time we started to have issues was when I had to change the Breakers out with AFCI Breakers.

Cornelius, Sounds as if there is an issue with the breaker that you are using for the lights. If the breaker for the lights or outlets is causing the main breaker to reset or trip, then check the light breaker for faults or wiring issues. You may want to have a professional assist you as working in a main breaker box can be a safety issue if you do not have much experience with high voltage. -RR

I have a problem, my main power box trips when I switch the lights breaker on but when the light breaker is off, all of the electrical outlets are working, please what’s cause of the problem?

installed new light circuit, when the switch is in off position and I flip breaker on, the 2 light fixtures are on, hit the switch to on a the breaker trips. Power is getting to the switch, in off postion the circuit works, turn the switch to on and breaker trips. I must have a wire from switch in wrong plsce or wrong on the first light of two in the circuit.

The breaker started tripping when I added a second light on a combination switch and the switch is also powering a second room and all my wiring is done right, I’m assuming is that the breaker is overloaded but I will like a second opinion or confirm my deduction

I hung a new ceiling fan, the old one was just wired into the neural side of the wiring, all hooked up on the white wire. I rewired the new one into the wiring like it should be, black to black, and white to white, now when i turn on the wall switch it trips a breaker.

Q: Every few hours—sometimes minutes!—my living room and one side of my kitchen lose electrical power. I’ll check the breaker panel and, sure enough, a circuit breaker has tripped…again. Should I call an electrician, or is there a simple DIY fix I can try first?

A: While it’s frustrating when a circuit breaker keeps tripping, they are important safety mechanisms. Designed to shut off the electrical current when something goes wrong, circuit breakers are one of the best ways of protecting a home from an electrical fire. “When a circuit breaker trips, typically it is because we use too much electricity, which causes it to overload and turn off,” says Christopher Haas, expert electrician and owner of Haas & Sons Electric in Millersville, Maryland. For those who need an electrical panels 101 refresher course or aren’t sure how to reset circuit breakers, each breaker has an on/off switch and controls a separate electrical circuit in the home. When a breaker trips, its switch automatically flips “off,” and it must be manually turned back on to restore electricity to the circuit. For those wondering, “Is it dangerous if a circuit breaker keeps tripping?” the answer is that it can be, depending on the source of the problem. An electrician can ultimately deal with the root issue, but a little sleuthing will reveal whether it’s something that’s easily remedied.

In many cases, the cause of a circuit breaking tripping is an overloaded circuit.

A circuit overloads when more electrical current is being drawn through the wires than they can handle, tripping the circuit breaker. If this happens, there may be a few additional signs:

• Buzzing noises coming from outlets
• Devices charging slowly
• Electrical outlets not working
• Flickering lights
• Scorch marks on outlets and light switches

If a circuit breaker keeps tripping in one room, homeowners can test for circuit overload by turning off all the switches in the affected area and unplugging all appliances and devices. After the breaker is flipped back on, the devices can be turned back on one at a time, with homeowners waiting a few minutes in between to see if the circuit remains on. If the breaker trips before all the appliances are turned on, the experiment can be repeated, this time turning them on in a different order. It may be necessary to do this several times to find out how many appliances can be operated at once before the circuit overloads.

“As a short-term solution, you can unplug unnecessary appliances to prevent tripping circuit breakers. You may still get some trips, but you can limit them by unplugging devices that you don’t need to use,” advises Dan Mock, vice president of operations at Mister Sparky , an electrical company with 90 locations in the U.S. The best long-term solution, however, is to pay an electrician for the cost to rewire the house and add additional circuits. The cost to replace an electrical panel is about $1,274 on average.

Other times, the issue may be caused by a short circuit.

A “short” circuit means that two wires that should not be coming into contact are inadvertently touching, triggering a sudden surge of electricity through the wires. A short can occur in an outlet, a switch, or within an appliance if wires are loose or have been chewed through by mice or pets. Some signs of a short circuit include:

• Popping sounds
• Discolored outlets or switches
• Burning smells

Testing to see if an appliance has a short is similar to testing for an overloaded circuit. When an appliance that has a short in its wiring is turned on, it will immediately trip the circuit. Homeowners can also try plugging it into an outlet in a different room. If the breaker for that room trips, there’s a short in the appliance (if it’s unclear what breaker goes to what room, the breaker can be identified with one of the best circuit breaker finders ). Electrical shorts can be a major fire hazard, so it’s a good idea to call a licensed electrician for this circuit breaker repair. It’s wise to stop using the outlet or appliance until a pro takes care of the problem.

Another potential cause of a circuit breaker tripping is a ground fault.

A ground fault occurs when the electricity running through a home’s wiring diverts from the wiring loop and travels to the ground, usually due to faulty wiring or water infiltration in an outlet or switch box. Water is a conductor, which is why walking through puddles is often listed as something not to do in a power outage in case of downed power lines. Once water makes contact with wires, electricity can jump from the wiring loop and follow the water trail. This creates a surge in electricity leading to a tripped circuit breaker. If a person comes in contact with the electricity that is on its way to the ground, this can result in electrocution. Homeowners may notice a few signs of a ground fault, including:

• Tripped GFCI (ground fault circuit interrupter) outlets;
• A burning smell coming from an outlet; and
• Lights flickering.

Newer electrical breakers have features designed to protect against the danger of ground faults. According to Haas, “Ground fault breakers sense electricity going to earth as opposed to going through the wires of the circuit. You’ll find [these] for bathrooms, kitchens, garages, exteriors, and basements.” GFCI outlets are another safety feature that shut off the electric current within a fraction of a second of sensing a ground fault.

If a ground fault is the problem, the cause of the errant water must be discovered and repaired, and any damaged wiring must also be replaced. It’s also a good idea to install GFCI outlets in rooms where water is commonly used. A GFCI outlet costs $210 on average.

Sometimes a bad or worn-out circuit breaker can be the culprit.

In some cases, the circuit breaker itself may be faulty. Breakers that are old, damaged, or were installed incorrectly may trip frequently for no apparent reason. Alternatively, faulty breakers may not trip when they are supposed to, leaving the home at risk of electrical fire. Some signs of a bad circuit breaker include:

• The circuit breaker getting hot and tripping frequently;
• The circuit breaker won’t reset;
• It has been over 10 years since the breaker was last serviced; and
• The breaker has scorch marks.

An important electrical safety tip to keep in mind is that resetting a breaker over and over again can cause what is called an arc flash, which is a small electrical explosion that can be deadly. If resetting the breaker once does not remedy the issue, it’s a good idea for the homeowner to hire an electrician near them who knows how to replace a circuit breaker safely. Mock warns, “Don’t take any chances with circuit breakers. Instead, call a licensed electrician who knows the safe ways to replace breaker boxes, upgrade circuits, and diagnose potential electrical problems in your home.” Wiring a breaker box is a job to leave to an experienced electrician.

A professional electrician can help determine the specific cause of a frequently tripping circuit breaker.

Most circuit breaker problems—aside from those explained in the sections above—will need to be inspected and addressed by a licensed electrician. According to the Electrical Safety Foundation International (ESFI) , each year “thousands of people in the United States are critically injured and electrocuted as a result of electrical fires, accidents, [or] electrocution in their own homes.” While homeowners may be tempted to save on electrician costs by attempting circuit breaker replacement or repair themselves, electrical work is not suitable for casual DIYers. “Yes, you have to pay, but you can save many hours of head-scratching by hiring an electrician. Electricians will also have all the right tools for diagnosing and repairing the circuit,” Haas adds. “Lastly, they will come with a warranty/guarantee should something arise, and they will typically return at no additional cost.”

Why a Circuit Breaker Trips When the Light Switch is Turned Off?

Written by  Edwin Jones  / Fact checked by  Andrew Wright

Do you want to use electricity without problems, but your light switch is a headache? If a circuit breaker trips when the light switch is turned off, most likely, it’s a result of a common wiring mistake. However, there are other reasons you should keep an eye on.

You’ll never know what will happen if you let this malfunction go unaddressed, so keep reading and see the listed possible reasons. It is necessary to determine your next step on this matter to maintain a healthy power source for your home.

Table of Contents

You Have a Miswiring in a Switch Loop Setup

A double throw switch is causing the problem, what if your switch is a single pole single throw, a loose wiring connection.

When you install lights, you buy new fixtures, switches, and perhaps a new set of wiring too.

Now you think you did the proper process — hot-to-hot wire and neutral-to-neutral wire, but in the end, the light switch trips breaker when turned off. Even though you reversed the way you plug the wires, the result stayed the same. This pain in the butt frequently happens when you have a switch loop set up.

A typical DIY guy mistake in a switch loop setup is when all black and white wires are connected. This miswiring causes the light to turn on even though the switch is off. Because it’s improper, it shorts the circuit and trips the breaker when the switch’s on.

To properly rewire this connection, you will need a marker and proceed to the following steps:

• First, the circuit breaker’s black wire connects to the white wire and other black wires that feed other devices.
• Remember to put a black marker on both ends of the switch and the light.
• Then, connect the circuit breaker’s white wire to the light’s and other devices’ white cables.
• Next, connect your switch’s black wire to the black wire for the lights.
• Finally, link all the ground wires together and to the ground screw from the lighting fixture and the box.

If your residence had a history of a bad renovation or electrical rerouting by an untrained contractor, your wirings might be in trouble. It is time to remove the cover panel of your switch box and investigate the situation of your switch inside the box.

A breaker that trips from an off light switch is not common among households today. This occurrence happens because of poor wiring of a light switch like the “Single-Pole, Double Throw” switch.

You’ll know you have this kind of switch when it doesn’t have ON and OFF markings on the switch toggle.

It’s a bad sign if your switch is leaning on the side of the grounded box where it is mounted. A switch is in an improper position when the switch pole screw lies against the switch box and the runner is shorted, which causes the fuse to blow when you turn the lights off.

Also, the breaker will trip if the runner short circuits to the ground or neutral wire somewhere along the wiring’s terminus.

If you have double-throw switches for a three or four-way switch, look out for a shorted traveler wire. It’s possible a switch was removed, causing the travel wire to short-circuit ( Read now how to test a shortstop circuit breaker here ).

A standard single throw switch is a typical switch for a light fixture. You can typically find this at home with three screws for hot wires and a ground wire. Its clear difference from a double throw is that the switch toggle has an ON and OFF indicator.

Now, what’s the catch when you have a single pole, single throw switch? Will you have the same dilemma as with the double throw? Well, technically, the answer is yes. You can still experience a problem where a breaker trips when switch is turned off, but for other reasons.

If it’s a standard switch, it is easy to blame the button itself when you have a difficulty like this. The controller can be defective due to a manufacturing failure. However, a simple wiring mistake can trigger the breaker to trip just by turning the switch off.

If the ground wire and the hot wires are close enough to each other, toggling the switch can cause a slight movement that contacts them, then BOOM, a ground fault.

There’s also a possibility that the switch is in neutral. Keep an eye on this wiring mistake because you’re turning the power to the neutral and not the hot wire. Reverse wiring is a huge no-no, so try to fix it as soon as possible.

The fourth and simplest possible reason is a loose wire. Just like other devices at home, your switch gets old, and so does your breaker. When an electrical safety device comes to the point where you’ve been using it for ages, its wiring will eventually give up.

Sloppy wiring of an old switch can cause a breaker to trip, even with the slightest movement of switching it off. Like other issues stated earlier, a loose connection triggers a ground fault or a short circuit .

Furthermore, general wear and tear to your breaker and switch wirings result in repetitive breaker tripping. If you think loose or faulty wiring is not a big deal, watch this video by Andrew Pace:

It is necessary to check your terminal screws and wiring insulations from time to time. Sometimes an old wire turns brittle, and its insulations become damaged, so never let this happen to your switch and CB.

Wiring on the brink of destruction won’t only compromise a breaker but also increase the risk of multiple hazards. Always mind your safety.

There are four possible reasons why your circuit breaker trips when the light switch is turned off. Check if you have a switch loop setup, double/single throw switch, or loose wiring connections. These will help you determine a specific matter causing this problem.

If it’s the wiring that causes the problem, proceed on a safety action immediately.

Addressing an electrical problem is vital for the welfare of our homes. Never take safety for granted, and face the trouble as soon as you can.

Does Your Circuit Breaker Keep Tripping? Here’s How to Find the Cause

Last Updated: May 6, 2023 Fact Checked

Common Causes of Tripped Circuits

Finding overloaded circuits, finding short circuits, finding ground faults.

Picture this: you’re watching TV or browsing on your phone when, suddenly, half the lights in your home turn off. You check your circuit breaker and flip one of the switches back to “ON,” but an hour later it trips again…and again. Sound familiar? Having your circuit breaker trip over and over can be frustrating, but don’t sweat. In this article, we’ll explain the most common causes of a tripped circuit breaker. Keep reading to learn which causes might apply to your situation, when to try do-it-yourself fixes, and when it’s best to call an electrician.

Things You Should Know

• The most common causes of tripped circuit breakers are overloaded circuits, short circuits, and ground faults.
• Test for overloaded circuits by resetting your breaker and plugging in devices until it trips again. The device that caused the trip is overloading the circuit.
• Test for short circuits by resetting your breaker and plugging in items into different sockets. The device or socket that always trips the breaker likely has a short circuit.
• Have an electrician test for ground faults if you’ve already ruled out overloaded and short circuits. Ground faults are too dangerous to test for on your own.

• For example, if your bathroom and kitchen are part of the same circuit—that is, the plugs in your kitchen and bathroom are all connected to the same switch on your circuit breaker—then the breaker might trip if you run your microwave and hair dryer at the same time.

• Short circuits often happen when wires come loose or get damaged by corrosion or wear and tear, or even from an animal chewing through them. [3] X Research source
• Short circuits can occur in the wiring in your home or in individual devices. For instance, a refrigerator can have a short circuit due to a loose wire.

• Ground faults often happen due to water leaking into outlets or devices. They also occur when loose or corroded wires come into contact with ground wires, or when defective devices cause electricity to flow to a ground wire.

• If you have multiple devices sharing a single outlet in the area affected by the tripped breaker, it’s likely that that group of devices is causing the overload. [6] X Research source

• Wear safety goggles or stand to the side of a breaker when flipping a switch to “ON” in case of sparks.
• If the switches aren’t labeled, narrow down the affected area by flipping the switch to “ON” and checking which devices and lights turn on again.
• If multiple switches tripped at the same time, there might be an overloaded circuit in more than one area of your home, or you may have another issue such as a short circuit or ground fault.

• If none of the devices immediately trip the circuit breaker, it’s possible that your circuit isn’t getting overloaded right away. Leave the devices plugged in and turned on for a few minutes to see if the breaker trips again.
• If the breaker trips after several minutes, try the process again, but leave 1-2 less important devices unplugged. Eventually, you’ll find a combination of devices that doesn’t trip the circuit breaker.

• Leave your devices plugged in and on for a few hours. If the circuits are not overloaded, the circuit breaker shouldn’t trip.
• If the circuit breaker trips for the same part of your home again, plug additional devices into other outlets. You may need to try different combinations of plugs and outlets to see which combination doesn’t overload your circuits.
• If you try several combinations and the breaker continues to trip, it’s possible that you have a short circuit or ground fault somewhere in your home.

• If devices are plugged into surge protectors, unplug each device from the surge protector before unplugging the surge protector itself.

• If the circuit breaker trips whenever you plug something into a particular outlet, you probably have a short circuit in that outlet.
• If one particular device always trips the breaker, but other devices don’t, you probably have a short circuit in that particular device.

• If the device you want to test is too large to move—such as a kitchen refrigerator or washing machine—use a long extension cord to reach other outlets.

• If you find a short circuit in an individual device, check if your product is covered by a warranty. If it is covered, you might be able to get it fixed or replaced for free.

• Tell your electrician which outlet or area of your home is affected by the tripped circuit breaker. This will help them narrow down the exact problem.
• Avoid using sockets that appear water-logged or that show signs of water damage.

Light Switch Trips Breaker: What To Do?

Don’t you just hate it when a light switch trips the breaker? Aside from being annoying, the underlying issues may cause serious damage. What can you do about it, and how to keep it from happening again? Let’s find out!

What Does a Tripped Breaker Look Like?

Get your hands ready, check for water deposition, don’t touch a breaker switch with high amperage, turn appliances and devices off, adjust your circuit breaker, check your breaker panel, know when to call an expert, avoid overloading one circuit, check and replace old wiring, install your light switch properly.

When you open your electrical panel, there should be multiple breakers on a board.

Each of the breakers in the panel regulates a different electrical circuit in your house and has a switch with numbers printed on it. Typically, each one should be labeled with the name of the area that it controls.

Keep in mind that power cannot flow through the circuit until the switch is manually turned back on after a breaker trips. This causes the switch to flip to the “OFF” position automatically.

For example, if the light switch that caused the trip is located in the kitchen, you can easily locate the breaker switch labeled “Kitchen.”

You’ll probably see the “Kitchen” breaker switch tipped to the “OFF” side or right in the middle between “ON” and “OFF.”

What Are the Safety Precautions to Take?

Before we get down to business, let’s make one thing clear: safety is still our top priority.

You may be in a rush to get your problem fixed, but temporarily losing your power supply is so much better than losing an eye or a finger.

Here are some safety tips to keep in mind:

Working on electrical systems with wet hands is extremely dangerous. So, we recommend that you start by drying your hands properly before troubleshooting your light switch.

Then, you can wear protective goggles or use electrical-insulating gloves.

Water won’t always accumulate on the breaker, but it does happen occasionally. That’s why it’s always good to examine your panel carefully. If it seems wet, don’t touch anything.

You might notice a number on the breaker switch that indicates the amps or the measure of electrical current that flows in that circuit.

If the number is 25 or above, it’s better to leave it to the professionals. Meanwhile, if your breakers aren’t labeled at all, it isn’t recommended to attempt to reset them.

Sometimes, simply flipping your light switch can trigger a trip on your circuit breaker.

This is a common issue with newly installed lighting systems. However, circuit breaker trips from flipping a light switch may also be caused by a short circuit due to faulty or damaged wires.

Either way, let’s take a look at how you can approach the tripped breaker.

Start by unplugging all appliances, lamps, and other gadgets in the affected area.

Go to your electrical service panel and check if a particular breaker has tipped to the “OFF” side.

In some cases, the breaker may not tip completely to the “OFF” position and may sit between both sides. When this happens, you can move the switch over to “OFF” first before pushing it back to the “ON” side.

Now, there is a possibility that the switch will automatically tip back to “OFF” after you’ve just switched it to the “ON” side. If that’s the case, don’t try to reset your breaker once more. Instead, seek help from an expert.

After successfully resetting your breaker, flip your light switch to see if the issue is fixed.

If overloading is the culprit, your power will come back after switching your lights on or plugging your devices one at a time.

There may be instances when the light switch doesn’t turn on, but other plugged-in equipment may receive power. If that happens, you can suspect that the problem might have originated from your light switch.

If the previous steps don’t cut it or you’re uncertain about the root cause, it’s best to call your electrician.

Having your breaker trip twice in a row should already sound an alarm, and you shouldn’t try to fix the problem on your own.

The primary concern here is that repeatedly resetting your breaker due to recurrent trips can be risky and may result in overheating.

After all, serious complications and accidents are on the line, including the following hazards:

• Overheating of internal components that may lead to fires
• Visible damages like scorch marks on power outlets, sometimes with the presence of a burning smell and smoke
• Sparks on the breaker
• Odd clicks or buzzing sounds from the outlets or switches

How To Prevent Your Light Switch From Tripping the Breaker?

Since dealing with a light switch that trips the breaker is a hassle, you might want to check out these preventative tips and tricks:

Circuit overload is the main reason behind trips. That’s why it’s better to avoid plugging your bulb into one circuit with a ton of connected appliances.

Remember that using an extension cord to maximize connectivity will only make things worse. If you badly need to use multiple devices, try plugging your other devices into a different circuit connection or getting a new circuit installed.

Be sure to unplug devices or appliances that aren’t in use.

If your electrical wires have been sitting there for many decades and you start to experience frequent trips, they’re probably worn out.

You might even notice that rodents have damaged your wiring. So, it’s good to have your old wires replaced by an electrician.

We’d recommend double-checking that you’re using compatible fixtures before installing new lights or replacing any part of the lighting setup.

Then your electrician can check that all screws are all tight and wirings are connected properly to reduce the risk of tripping.

Why Does My Light Switch Keep Tripping The Circuit Breaker?

Why does my light switch keep tripping the breaker.

Your light switch keeps tripping the breaker because of a loose wiring connection or a ground fault. A faulty light fixture, a faulty light switch, or damaged wiring is another reason your light switch keeps tripping the breaker.

Loose wiring connection

A breaker can trip at the slightest switch movement if the switch is old and poorly wired. If any of the wire becomes loose or damaged, it can cause potential ground faults and short circuits that would result in a tripping breaker.

Turn off the switch’s power supply, remove the cover, and check whether the terminal screws are loose. If they are loose, ensure the screws are securely tightened.

Ground faults

This occurs when a live wire makes contact with a metal section of the switch housing or another component of a similar nature. This can cause shocks and also trip the breaker. Ensure there are no ground faults by thoroughly checking the wiring in every possible location.

Faulty light fixture

If a light fixture is damaged, it can cause a breaker to trip. The wires can break apart in an old light fixture and cause a short or ground out. You should turn off the power and check the light fixture for any damage.

If the light fixture is faulty, you should replace it with a new one.

Faulty light switch

Another common reason for a light switch to trip the breaker is a faulty light switch. A faulty light switch might cause a short circuit and the breaker to trip. The breaker may trip because an old light switch has cracked and is no longer operable.

The wires become fragile and cause circuit overloading or short. Before examining the light switch, make sure the breaker is turned off. Replace the light switch if it turns out to be damaged.

Damaged wiring

A rodent living in the wall may have chewed on the wires. This will break the wires and cause a short trip to the breaker. You will have to fix or replace the wiring.

How to fix a light switch that keeps tripping the breaker?

You can fix a light switch that keeps tripping the breaker by rewiring the wires connection or replacing the light switch. Replacing the light fixtures or tightening the wires is another method you can use to fix a light switch that keeps tripping the breaker.

Rewire the wires connection

Because of the improper connection of the wires, when the switch is turned on, the breaker will trip because of the short circuit. Rewiring the wires connection is essential to prevent your light switch from tripping the breaker. Here is how to rewire it;

• First, connect the black wire of the circuit breaker to the white wire and other black wires that feed other devices.
• Remember to put a black marker on both ends of the light switch and the light.
• Then, connect the circuit breaker’s white wire to the light’s white wires.
• Next, connect the black wire from your switch to the lights’ black wire.
• Lastly, connect all the ground wires and the ground screw on the light fixture and the box.

Replace the light switch

A faulty light switch can short out and trip a breaker. If you notice the light switch is faulty, replacing the light switch is vital. Here is how to replace it;

• Turn off the circuit breaker.
• Take off the cover of the switch or outlet plate.
• Loosen the screw that holds the switch and the wires together.
• Connect the new switch.
• Put the switch in the new electrical box.
• Replace the cover plate for the switch.
• Tighten the screws and cover the plate with a screwdriver.
• Restart the power.

Note: Make sure there are no exposed or frayed wires or use a wire stripper to retouch them to meet your needs. Connect the new light switch the same way you disassembled the old one.

Replace the light fixtures

If a light fixture is damaged, it can cause a breaker to trip. You can fix this by replacing the light fixtures. The following are easy DIY steps to replace it;

• Turn off the power of the old fixture.
• Loosen the screws that hold the plate to the wall with a standard screwdriver to access the fixture.
• Unscrew the black, white, and copper wires.
• Take off the old fixture.
• Connect the new fixture.
• Secure the new fixture and adjust the length
• Screw back the black, white, and copper wires.
• Turn on the power and try the new fixture!

Tighten the wires

A loose wire will cause your breaker to trip, which can lead to other problems. Tightening loose wires in your light switch will stop the breaker from tripping. Here is how to tighten it;

• Turn off the power
• With the power turned off, you can take off the cover plate
• Use a flashlight to carefully look at the screw terminals inside where the wires are connected.
• If you find loose wire, tighten the screw terminals on the wires carefully.

Why does my light switch keep tripping the GFCI?

Your light switch keeps tripping the GFCI because the neutral connection on the switch is tied to the ground or a faulty GFCI receptacle. To make sure there are no electrical hazards, test any GFCI outlets. An issue could arise, and the breaker could trip if the light switch wire is connected to a malfunctioning GFCI outlet. When a GFCI outlet fails the test, it must be replaced.

A short circuit or an overload is another reason your light switch keeps tripping the GFCI. The breaker trips because two wires are touching and conducting electricity between them. When insulation wears away, wires become brittle and potentially hazardous.

If you want to be sure there are no short circuits, check all the cables. If you detect any of the wire to be fragile or the insulation to be peeling, you should have it replaced. If replacing the outlet doesn’t fix the issue, the fault may lie with another outlet on the line or an appliance hooked into it.

Disconnecting everything from the outlets on the same line is a good way to determine if the issue is a specific device or the outlet itself. It’s possible that you’ll need to check each plug separately.

Why does my light switch keep blowing a fuse?

Your light switch keeps blowing a fuse because it is becoming overloaded, a faulty electrical item, or a short circuit.

An overload

Overloading the circuit is the most common reason for a fuse to blow. Circuits can only handle a certain amount of electricity, and every light you turn on or appliance you use adds to that amount. Overloading them will cause them to draw more power than they can handle, which will cause the fuse to blow.

In this case, you should be able to find the cause by looking for an outlet or an appliance that is being used excessively. Cut down on how much power is going into a single circuit. Find places to plug in on other circuits or unplug what you’re not using.

Faulty electrical item

One possible cause of your fuse switches blowing is a malfunctioning electrical device. There could be an issue with the wiring, or the device could simply be too old and worn out to function properly.

Looking at the fuse box could help you determine the source of the issue. With the help of clearly labeled fuse switches, you may pinpoint the damaged appliance to its circuit.

Short circuit

Short circuits are one form of electrical fault. When the live (black) wire comes into contact with the neutral (white), ground (bond), or metal (box) terminals, this is called a “hard short.” Simply put, a short circuit occurs when an electric current takes a direction it shouldn’t.

Every time this occurs, the circuit is subjected to excessive heat because an excessive quantity of current flows through it. When this occurs, your fuse will blow. This happens due to several factors, including but not limited to: rust, dampness, insects, and other damage to the wiring and accessories.

The following is a simple step to fix a blown a fuse;

• Unplugs electrical appliances
• Then, disconnect the fuse box from the primary power source.
• Find the fuse.
• Identify the faulty fuse.
• Unscrew the faulty fuse and screw in the new one; it must be the same as the old one.
• Try out the new configuration.

Note: If your fuse keeps blowing, it could signify a more serious electrical issue. A fuse may be short-circuiting owing to loose wire connections, damaged wires, or an internal wiring fault. While blown fuses can be repaired repeatedly, a professional electrician should be called in when the problem lies deeper in the electrical wiring.

How to Fix a Tripped Circuit Breaker That Won’t Reset

• March 26, 2024
• Electrical Tips

Have you ever had a circuit breaker trip and found that it won’t reset? It’s a common problem, and one that can be frustrating when you’re not sure what to do.

The most common reasons for a circuit breakers that won’t reset are:

• Damaged breakers
• Electrical shorts
• Loose wiring
• Damaged insulation

In this post, we’ll walk you through how to check for each of these common reasons, and discuss how to fix them.

Why circuit breakers trip

A circuit breaker is a safety device in your home designed to stop the flow of electricity if there’s an overload, which can help prevent fires. When the current flowing through the circuit breaker becomes too much for it to handle, it “trips” and shuts off the power to prevent a fire from starting.

Most of the time, resetting a tripped circuit breaker is a simple matter of flipping the switch back to the “on” position. However, sometimes the breaker won’t reset no matter how many times you flip it.

First, try to reset the tripped circuit breaker

First, we should perform a basic test to make sure the breaker is actually malfunctioning. If you haven’t already tried manually resetting the circuit breaker, this is the place to start.

Locate your circuit breaker box and open the cover. Once you’ve located the tripped breaker, flip it to the “Off” position. Then, flip it back to the “On” position. You should hear a click as the breaker resets. If the breaker trips again, or simply won’t reset, there may be a problem with your wiring.

How to fix a tripping circuit breaker

Check to see if the circuit breaker is damaged.

If the circuit breaker trips and won’t reset, the first thing you should do is check to see if the switch is damaged. Circuit breakers are designed to trip when they become overloaded, which means they’re also designed to be flipped back on when the overload is resolved. However, if the switch itself is damaged or the electrical panel is outdated , it may not reset properly.

To check for damage, first make sure that there’s no power going to the breaker box by flipping all the switches to the “off” position. Then open up the panel and visually inspect the faulty breaker for any signs of burned or blackened areas. If you see any charring or burning around the switch, it’s likely time to replace it.

In some cases, you may be able to reset a damaged breaker by gently bending the switch back into place. However, this is only a temporary fix and the breaker will eventually need to be replaced.

We recommend that if you see any damage, it’s best to replace the entire circuit breaker rather than just the switch.

Check to see if there’s an electrical short

Another reason why your circuit breaker won’t reset after tripping is because there’s an electrical short somewhere in your home. An electrical short occurs when there’s too much current flowing through a wire, causing it to overheat and potentially start a fire.

To figure out if there’s an electrical short, the first thing you should do is turn off all of the switches in your breaker box. Once everything is off, go around your home and look for any signs of an electrical fire, such as burning smells or smoke. If you see or smell anything suspicious, call a licensed electrician right away.

If you don’t see any signs of a fire, the next step is to identify which circuit is causing the problem. Start by flipping on one switch at a time and seeing if the breaker trips. If it does, leave that switch off and move on to the next one. Repeat this process until you’ve found the problem circuit.

Once you’ve identified the problem circuit, the next step is to figure out where the electrical short is located. The easiest way to do this is to start at the breaker box and work your way down the circuit until you find the problem.

If you’ve followed these steps and you believe there may be an electrical short, it’s important to call an electrician right away. They’ll be able to locate the source of the problem and fix it before it causes any further damage.

Check for loose wiring

Another common reason for a circuit breaker to trip is because of loose wiring. Over time, wires can loosen and become frayed, which can cause them to short circuit.

The best way to check for loose wiring is to listen to your devices and appliances for the sound of buzzing or crackling. One common culprit is buzzing light switches or outlets. If you don’t find a faulty appliance, note that this can also be true around the breaker.

If you hear these noises and suspect that your circuit breaker is tripping because of loose wiring, the best thing to do is call an electrician as soon as possible. Trying to fix the problem yourself could result in injury or even death.

An electrician will be able to quickly diagnose the problem and make the necessary repairs. In most cases, they’ll also be able to prevent the problem from happening again in the future.

Look for signs of corrosion

Another common reason for a circuit breaker to trip is corrosion. This is especially true if you notice any moisture or wetness in the electrical panel . Corrosion can cause the metal parts of the breaker to break down, which in turn can cause a short circuit.

Corrosion usually appears in the form of a white, chalky substance building up around screw terminals. Look for signs of corrosion, rust, or moisture around the circuit breaker.

If you suspect that corrosion is the culprit, call an electrician to have a look at the problem. Trying to clean or repair the corrosion yourself could result in serious injury.

Check for damaged insulation

Sometimes circuit breakers will have insulation around them to stop cold air from entering through the box itself. Damaged insulation is another common cause of tripped circuit breakers. If you have insulation around the box, inspect it to see if it looks damaged.

If the insulation around your electrical wiring is damaged, it could cause a short circuit. Once again, if you suspect that this is the problem, call an electrician rather than trying to repair the problem yourself.

Is it dangerous if a circuit breaker keeps tripping?

We are often asked if tripping circuit breakers are dangerous. If your circuit breaker keeps tripping, it could be a sign of an electrical problem in your home, up to and including serious fire risks. While it’s not necessarily dangerous if your circuit breaker trips occasionally, if it happens frequently, it should be fixed right away.

If your circuit breaker trips and won’t reset, don’t panic! Many times the problem is something minor that you can easily fix yourself. However, if you’re unsure of what to do or think the problem may be something more serious, always err on the side of caution and call an electrician . Trying to fix the problem yourself could result in serious injury or even death.

Resetting a tripped circuit breaker is a relatively simple process that most people can do on their own. However, if the breaker trips repeatedly or if you have any questions about your electrical system, it’s always best to contact a professional electrician for assistance.

Dishwasher Keeps Tripping Breaker? 5 Easy Checks

Dishwasher Keeps Tripping Breaker? Dishwashers are the kind of appliance that you can ‘set and forget’. Just load them up with dishes, turn them on, and let them work.

Still, it can be very confusing and frustrating when a dishwasher keeps tripping your circuit breaker .

A dishwasher may be tripping your breaker because of a problem with the heating element, loose or short-circuiting electrical connectors, a shorted transorb, a problematic control circuit board, or even a faulty wash motor. These issues could lead to the dishwasher drawing too much current/power, causing the breaker to trip as a way of avoiding anything bad from happening.

In this article, we’re going to explore the possible reasons this problem keeps happening. By narrowing down the cause, you’ll be able to find a solution and resolve the issue much quicker.

Let’s get started.

Useful Ways To Narrow Down The Cause

Table of Contents

When troubleshooting your dishwasher to figure out why it keeps tripping the breaker, it’s essential to ask the right troubleshooting questions. Here are a few to get you started.

Is The Dishwasher Plugged Into A GFCI?

Before anything else, check to see if your dishwasher is plugged into a ground-fault circuit interrupter (GFCI).

The GFCI is also a type of circuit breaker that protects you by tripping whenever it detects an electrical current imbalance. 

The difference here is that a GFCI doesn’t serve the whole house. Instead, it’s a wall socket into which you plug an appliance, such as your dishwasher.

Why This Matters 

Well, suppose your dishwasher is plugged into a GFCI.

Connect with an Appliance Repair Tech

Click here to use the chatbox to speak with one of our technicians. No in-home service calls. No appointments.

If the problem lies with the dishwasher, then the GFCI will be the one tripping, not the house’s circuit breaker .

That will help you confirm that the problem is localized to the dishwasher.

However, suppose the house’s circuit breaker trips even though your dishwasher is plugged into a GFCI.

In that case, the problem may be elsewhere, and not with the dishwasher.

Does Dishwasher Keep Tripping Breaker Mid-Cycle?

To narrow down the problem to its source, it’s also crucial to figure out when the tripping actually happens.

Does it happen before, during, or after a dishwashing cycle ? Or perhaps, does it happen randomly each time, with no clear pattern?

Why This Matters

You see, each stage of the dishwashing cycle will activate different components within the machine.

So, if the breaker trips during the same stage each time, then it’ll be much easier to know which part is causing the problem.

Dishwasher Keeps Tripping Breaker? Here’s Why…

Now, we’re going to look at the dishwasher components that may be causing the circuit breaker to trip.

We’ll explore the heating element, electrical connectors, the transorb, the control board, and lastly, the motor.

Heating Element

What it is: At the bottom of a dishwasher, you’ll find a heating element.

It’s typically in the shape of a horseshoe, with one electrical connector on both ends.

As the name suggests, the only thing this component does is heat up when the time is right.

In the dishwasher, that means the heating element activates to heat up the water during the wash and rinse cycles.

Towards the end of the dishwashing process, it’ll also heat up the air as part of the drying cycle.

Why it fails: A heating element can suffer damage in many different ways. It could’ve been hit by a plate or something else inside the dishwasher.

It could also have suffered a fault causing it to develop bumps or pits somewhere along the surface of the heating element.

Whatever the case may be, a damaged heating element could end up drawing far too much power or even cause a short circuit, causing the breaker to trip.

How to fix: Heating elements aren’t really meant to be fixed. Instead, it’s much easier to replace the damaged heating element entirely.

Start by referring to your user manual or checking online to find the exact heating element compatible with your dishwasher model.

If you decide to replace it yourself, be sure to disconnect all electrical and water supplies to the unit first.

Then, refer to the user manual to locate and access the existing heating element. The tools you’ll need are minimal, such as a small wrench or screwdriver.

Electrical Connectors

What it is: Every component inside your dishwasher has electrical connectors that allow them to form a circuit together.

These connectors help the part receive power so that they can function.

However, they also connect each component to the control board, coordinating and automating their activities throughout the dishwashing cycle.

Why it fails: Electrical connectors can cause problems in a few different ways.

For example, if they weren’t properly attached in the first place, they could simply come loose after many years.

That’s especially true when the connectors are exposed to the vibrations that the dishwasher generates.

Besides that, some of the wires to those connectors could also end up exposed.

When any of these things happen, it could create a short circuit within the dishwasher.

That’ll cause the breaker to trip as a way of preventing anything terrible from happening as a result.

How to fix: The solution to this problem is to inspect all electrical connectors for issues.

Loose connections must be reapplied and tightened, while exposed wires will need to be replaced.

Typically, this job is best left to qualified professionals who have the right skills, knowledge, and experience.

However, if you decide to do it yourself, always remember to disconnect the power and water supplies to the unit before accessing the dishwasher’s insides.

Transient Voltage Suppression Diode (or ‘Transorb’)

What it is: A critical electrical component inside a dishwasher is the transient voltage suppression diode, commonly known as the ‘transorb’ or ‘TVS diode’.

This component has a straightforward function: to protect the appliance from voltage spikes that might cause damage.

Such spikes usually happen in situations like lightning strikes and more.

Why it fails: The problem here happens when the transorb gets shorted for whatever reason. A shorted transorb can cause damage to the control board while simultaneously tripping your home’s circuit breaker.

How to fix: Thankfully, the transorb is a replaceable part.

First, refer to the user manual for any information on finding a compatible transorb for your particular dishwasher model.

Remember: it’s commonly referred to by other names like ‘TVS diode’ or ‘transient voltage suppression diode’.

Once you have your transorb kit, replacing the damaged one will require access to the electrical components inside the dishwasher itself.

That’s something that’s always best left to professionals. But of course, if you decide to replace it yourself, be sure to disconnect the water and power connectors first.

Control Circuit Board

What it is: Most appliances, especially dishwashers, have a component called the control circuit board.

The simplest way to think of it is as the ‘brain’ of the entire machine.

Once you’ve told it to start the dishwashing process through the control panel , the circuit board will then power and coordinate the whole process.

The right components will activate at the correct times to ensure that your dishes are washed and dried, all under the control board’s guidance.

Why it fails: Over time, control boards can experience damage .

Parts of it could’ve burned, or perhaps it may have inadvertently been exposed to too much moisture and heat from within the machine.

A damaged control board could lead to all sorts of unusual things happening, including the tripping of your circuit breaker.

How to fix: Control boards are a very common part to replace. The key is to find the correct one for your dishwasher model in particular.

So, be sure to refer to your user manual or call the manufacturer to identify the correct model.

A skilled technician could replace it for you, but if you’re feeling adventurous, be sure to disconnect the power and water supplies before you go tinkering inside the machine.

The control board is typically located within the dishwasher door but refer to your user manual to be sure.

Faulty Motor

What it is: Dishwashers will have a motor inside which powers the pump.

Doing so will help ensure that the pump has enough power to move water to wherever it needs to be.

Clean water will spray all over the dishwasher’s insides, while dirty water is then pumped out of the dishwasher.

Why it fails: Motors are mechanical in nature, and such parts tend to fail after experiencing plenty of wear and tear.

When that happens, the dishwasher motor could be pulling far more amps than usual.

That can cause problems, especially when other components in the machine, like the heating element, for instance, also start to power on at the same time.

All of that can result in a circuit breaker tripping due to the excessive amount of power that the dishwasher is drawing as a whole.

The breaker trips as a way of preventing anything terrible from happening due to what’s going on inside the dishwasher.

How to fix: Faulty motors need to be replaced. While it’s always best to refer to a professional, you could also replace it as a DIY job.

Just be warned; replacing a dishwasher’s motor is probably one of the most challenging parts to work on.

That’s because you will probably access the motor through the bottom of the dishwasher, requiring more time and effort than replacing most other parts.

As usual, disconnect the power and water supplies before starting. Since you’re accessing the bottom of the machine, you’ll also need to drain out all of the water beforehand.

Good morning My dishwasher KitchenAid trip the breaker and we here a electrical noise at the machine. Not sure at what cycle but I thinks is at the cycle when the pump should start to remove the water. This happen twice at the same time and when we open the door we could feel the hot temperature that seem to be normal but the dishwasher is full of water? Do you think the problem is the pump? Thant to get back to me

From what you describe, it sounds like it could indeed be a bad pump. Perhaps it has an internal short.

However, something else to consider: Is the circuit breaker an arc-fault style breaker? Many times, these arc-fault (AFCI) breakers are oversensitive and will nuisance trip under certain appliance loads. Please see this article for more info.

My L64 Ariston dishwasher trips the circuit breaker when it’s on the heat cycle (drying ) . The dishwasher does not trip but it trips the power to power points on opposite wall ( microwave etc ) thanks

I have lived in my new home 3 1/2 years. Dishwasher has not been used every day but recently used more often as our married grandkids and family are staying here while their home is being built. For the past 6 months, the dishwasher had been tripping the breaker. The breaker has a white “Test” button and the on/off switch. It is labeled “dishwasher/disposal”. Today, the dishwasher was set to run and tripped mid-cycle (it usually trips at end, leaving water in the bottom or a few days after last used). When it happens nether dishwasher or disposal will come on until re-set, but today after re-setting the disposal started working again but the dishwasher will not come on. Does this point to a specific component that had disabled the electrical connection or is my G.E. dishwasher fried?

Our dishwasher doesn’t actually flip the circuit breaker, but just stops working after the end of a cycle. No lights on the panel. I must turn off the circuit breaker and then turn it back on. Then the dishwasher runs for several cycles and goes dead again. Any thoughts?

Hey Jim I have the same problem can you respond to this if you find an answer thanks

I also have the exact same problem. Breaker doesn’t actually flip at all but about 24 hours later no lights on dishwasher and breaker needs turned off and then on again to get it to work. Did you ever find out how to fix this?

Did you ever find a solution to this problem? I am experiencing with a GE model thanks!

I have to plug in my portable dishwasher into to GFCI wall outlet. But that GFCI outlet suddenly started tripping when I use the dishwasher. So I decided to try it using an extension cord to a distance outlet that has no GFCI and isn’t even grounded. It works fine. Any thoughts?

I don’t know when or what happened but when we went to run the dishwasher, nothing. Checked circuit breaker and it was tripped. Rest breaker and as soon as I kicked the breaker on the dishwasher made a loud click or pop. Tripped breaker again and when I reset breaker and turn back on it pops and trips circuit breaker immediately. Any ideas? Thank you.

Hi Brandon, This sounds like you have a dead short in the dishwasher or in the wiring serving the dishwasher. If you are confident in your abilities, follow these steps:

With the breaker OFF, you can look inside the small junction box under the dishwasher (typically on the right side near the front of the dishwasher, behind the skirt). Undo the wiring connections on the black and white wires. Cap off (or tape off) the circuit wires (not the dishwasher wires) so that no copper is exposed. Turn the breaker on. If the breaker now resets, the problem is either with the connection you disconnected, or in the dishwasher itself. If the breaker still won’t reset, there is a problem on the circuit. That would require more extensive testing of the house electrical system. One possibility is that the circuit wire got pinched behind the dishwasher when it was installed. Vibration over time can finally rub through the wire sheathing and insulation.

Hope that helps!

Dishwasher breaker flips when dishwasher is off. House was gutted and all new wiring and appliances. Dishwasher can be off for 18 hours and dedicated breaker will flip.

Hi Douglas, Is it on an arc-fault breaker? You can tell by looking to see if the breaker has a small test button on it (usually blue, white, yellow, or pink, depending on breaker brand). Many appliances will trip these arc-fault breakers, even though there is nothing wrong with the appliance. The code requirement for these breakers was implemented before the technology was perfected. This has caused much frustration for us electricians over the years. I would disconnect the dishwasher and see if the breaker still trips. Is so, then the problem is in the circuit. If not, then the breaker does not like something in the dishwasher. Your only code-compliant option is to get a different dishwasher (ugh!) or try a different arc-fault breaker, hoping it is not as sensitive. Many folks have resorted to changing the arc-fault breaker out with a standard breaker and have been happy ever since. But I won’t recommend that due to liability issues.

Hope this helps!

My dishwasher is on an kitchen island, I do not know if it’s plugged into a GFCI but it has a switch (like a light switch) to control the power. Sometimes the breaker flips midcycle, sometimes it flips when it’s not in use at all. On a related topic, my GFCI plugs on the same kitchen island flips as well however it’s on a separate breaker. Should I start by replacing both breakers to see if that resolves the issue?

Yeah, try to replace breaker first.

Thank you My AEG favourite has blew up the main suppressor twice! After repair it tripping RCD breaker 10min from beginning of the washing cycle and at 20min before the end of te end cycle! That’s happening from time to time Not always. Looking forward to hearing from you Michael

CFGI flicks midcycle. Home is 50 years old. Cfgi is new seems to only do it when draining. When they redid the kitchen they made it kind of impossible to pull dishwasher (2ish years old probably based on model) out. Trying to see if I have options to possibly fix it with limited access. Any thoughts?

Why do you need CFGI for the dishwasher? Do you live in California?

So the weird thing is the CFGI that’s flicking is on a separate breaker. The dishwasher is on a dedicated line and we have now gotten an electrician to come out and check breaker and CFGI to make sure wired correctly everything checks out but Dishwasher still flicks at the exact same time in the cycle. About midway through the wash near a hard drain and restart of water flow. We tested draining nothing happened it’s just that one part the flicks it.

Both the breakers for the dishwasher and microwave are tripping should I cal an electrician first?

Had my LG dishwasher for almost 2 years before it started tripping the breaker. Spent all together $200 to have it repaired. The first guy fixed it for 45 days the second guy said to change the amp on the breaker from 15 to 30! Does that even make sense?

The guy telling you to increase the amp of the breaker should not be allowed to call himself an electrician! Circuit breakers serve a purpose: to cut the power and prevent your electrical circuit from overheating and cause fire. A tripping CFGI is something entirely different. It means that current is ‘flowing away’ to ground. I don’t know the rules for the US but here in Belgium (230V) CFGI’s are mandatory for ‘wet’ environments (bathrooms, kitchens…) and should trip at 30 milli amps. The entire circuit of your home should be protected with a CFGI of 300mA. Stray current, even very low amps, might not trip the circuit breaker but can be lethal when you are in bath or taking a shower. If you have no knowledge of electricity, please don’t start fixing it yourself but call a skilled electrician. It can save your life.

My GE dishwasher randomly chirps and comes to life and occasionally has no power all when not in use?

1. Loose power connection 2. Faulty control board

For no rhyme or reason my dedicated dishwasher circuit will trip… ??

Our Bosch dishwasher trips every end of the cycle. Technician inspected and said there is no issue found on heating element, but he can’t locate the exact issue. Does it make sense to replace breaker to try?

My dishwasher will trip on its own dedicated breaker a half hour or so after it completes its cycle. It runs all the way through but will trip after cycle completion. It is on its own dedicated breaker and I can’t figure out what is happening. Any ideas?

So, what if it trips the breaker mid-cycle? I know the pump is running; I can hear the water flowing/cascading…pretty sure it’s not the heating element; it doesn’t trip at the beginning or end of the cycle. Just mid-cycle. Once the breaker gets flipped back, it runs until complete. Any help would be appropriated!!!

I think you just need to replace the breaker

What a highly useful post! Thank you so very much for helping out the DYI community. I live quite remote for service and being handy helps with excessive service costs. Servicemen are quite valuable, but simple fixes help me fix this type of smaller problem!

You are welcome

Brand new house and a brand new Whirlpool dishwasher on its own dedicated circuit in the breaker. The dishwasher just started tripping each time we attempt to run it either at the beginning, middle or end of its wash cycle. Incredibly frustrating.

I had same problem, cleaned the filter (didn’t know about it for 1st year) on the bottom and it was fixed

Thank-you for the very insightful information.

Smart switch trips circuit breaker

ge brand switch and add on switch trip breaker when used can someone help me

Sounds like there’s an overload on the circuit or the switch is wired incorrectly.

Breakers trip because something is wrong. How long has it been connected and working before the breaker started to trip. If since install then definitely sounds like a wiring issue. If recently then more than likely the circuit is overloaded or there a wire has been compromised (frayed).

I’ve checked and rechecked the wiring of the switches and it is correct.in the box where the primary switch is being located there is a second cable on a different circuit. a (black and a white) both capped off in the back of the box. I used the neutral(white) from that circuit as it is the only neutral in the box. Since this afternoon when i posted this i found out that the CB on this circuit is an AFCI. which will trip in this situation. My question now is, what would it hurt if i changed out the AFCI CB with a standard CB?

Depending where you live, it may violate code to remove the AFCI, you need to figure out why it’s there in the first place. Also if you are using the neutral from one circuit and the live from a different circuit that can always cause weird stuff and is not recommended and again is probably a code violation.

Here’s a discussion about that with the code references:

Is this a new installation or one that was working?

If one that was working but just started to do this - then the switch has failed and need to be replaced.

If it is a new install then your wiring is incorrect - more than likely you have a short loop in your traveler line that goes back to your load line (black wire). That is typically what causes a breaker trip when you attempt to use the switch.

since the circuit for this device has a neutral in the box where my add on switch goes but not one in the box where the smart switch goes(this box for the smart switch has another cable in it from a different circuit) can i use this second circuit (hot, neutral and ground) for my smart switch while using the neutral with the add on switch in the other box ? will this work as only the ground, traveler and neutral pass thru the add on switch.

You have to think of this linearly:

• Both the add-on and the master need neutral (white) and ground.
• you need a dedicated traveler between the two (typically red) -the Master needs load (black).

Do not cross or mix-up these. Logically, a typical two location 3-way switch arrangement is done in two ways: I’m assuming you have construction in the last 20~ years where you have neutrals in all of your boxes.

14/2 romex - white, black and ground (3 total wires) 14/3 romex - white, black, red and ground (4 total wires)

• the circuit feed (usually 14/2 romex), remote/traveler (can be either 14/2 or 14/3 romex) and then the fixture (usually 14/2 romex) all in one box.
• For this, one you need to identify exactly what wire you have between the master and the remote side - if you have 14/2 then you will have to identify and isolate this black wire because you will need to make the black line here your traveler. -if you have 14/3 then you will use the red line as the traveler and just cap off the black line on the remote side and it will be unused. -As I said, you should have 14/2 romex going between the two switch locations and you will just connect the neutral (white) to jump it between the two switch locations.
• the circuit feed (usually 14/2 romex) is in the remote box, remote/traveler (usually 14/3 romex) and then the fixture (usually 14/2 romex) is in the master box.
• For this, one you still need to identify exactly what wire you have between the master and the remote side - Your black wire will connect over to the master switch across the traveler romex and the red is your traveler. -As I said, you should have 14/2 romex going between the two switch locations and you will just connect the neutral (white) to jump it between the two switch locations.

Do Not combine circuits. If you are still having issues after trying to make sense of this then you’ll need to call in an electrician.

The AFCI isn’t the issue. My whole house is covered by AFCI breakers where code requires them and I don’t have this issue with GE or other smart switches. Open up the boxes, take pictured and email to Smartest House support. They will help.

It’s a factor if the OP is using the live from one circuit and the neutral from another. Then the AFCI won’t work properly.

If you use a neutral on a different circuit the afci will detect a power differential (power out on line does not equal power in on neutral) and trip. You should never use a neutral from a different circuit (code violation) and you can’t use a neutral from a different circuit on an afci because it will trip.
