Stuck trying to stop your dishwasher from tripping the breaker?

Unfortunately, this is a known issue and can be super frustrating when it happens. After all, dishwashers should make our lives easier, not the opposite.

If your dishwasher keeps tripping the breaker, there’s a good chance you’re using GFCI plugs, or you have loose circuiting connectors. Having a faulty heating element, motor, or circuit board could also explain the issue.

Don’t worry, though. You’ve come to the right place to fix all of these problems.

5 Reasons Why Your Dishwasher Keeps Tripping Your Circuit Breaker (With Fixes)

Although dishwashers are great, if one or more of their components are damaged, you’ll experience all sorts of issues while trying to use them.

This is why I’ve prepared a list of the most common reasons why your dishwasher keeps tripping your breaker. These are:

#1 GFCI Outlet

Before doing anything else, I recommend checking what type of plug your dishwasher is plugged into.

A GFCI outlet is designed to detect changes in current, such as surges or interruptions in the power.

The issue with a dishwasher is that it does not get a constant flow of power while it is being used.

Instead, it does draw more power during certain cycles, which means that it will cause issues and might end up causing the GFCI socket to trip and shut off the circuit breaker.

This is a typical issue and if your dishwasher is plugged into this type of outlet, you may want to change it to a regular socket.

#2 Heating Element Issues

You may not know this, but your heating element is on the bottom of your dishwasher. It is exposed, so it can get hit by dishes.

If the heating element is not working well or is damaged, it can trip the breaker and cause other performance issues.

This is why, you need to test it with a multimeter, and if it’s defective, please replace it.

To do it, you simply need to unplug the dishwasher from the wall outlet. Then, remove the heating element and put in the new one. Then, plug your appliance back in and see if the issue is taken care of.

Issues with the heating element can also cause the dishwasher to stick in one more or not go from one cycle to the next.

#3 Loose or Short Circuiting Connections

Your dishwasher uses a range of different electrical connections that allow it to function. These supply the necessary power to move through each wash cycle.

Connectors that are not hooked up properly, that have faulty wiring, or that are short-circuiting can cause the entire circuit to trip to help prevent a fire.

The best way to take care of this issue is to take a look at the connectors themselves.

If you notice that the wires are not connected properly or that they are damaged or loose, you should either replace them or repair them.

If you are not sure if you can do this on your own, it may be best to hire a professional or to get someone that is experienced in repairing this type of issue.

#4 Shortened Transient Voltage Suppression Diode

The transient voltage suppressor is a piece of electrical wiring that is used to help protect the dishwasher from spikes in voltage that could cause major damage to the machine.

This kind of spike usually happens when lightning strikes or when the house shorts. In some cases, the transient voltage suppressor can become shortened and can end up causing issues.

It can damage the dishwasher, trip the circuits in your home, and cause a power outage.

To fix this, you do need to make sure you are reading the manual and paying attention to the particular transient voltage suppressor that works for your dishwasher. Your manual is going to tell you where to find it and where to replace it.

This is a repair that is almost always best to leave to a professional or to someone that has done this type of work before and is therefore able to repair it without further trouble.

If it is shortened or damaged, it does need to be replaced in order to make sure that it is going to work properly and that it is not going to damage the dishwasher.

#4 Faulty Wash Motor

Having a faulty motor could also explain why your dishwasher keeps tripping the breaker.

You see, all dishwashers have a motor that helps to move the water up and around the dishwasher. However, if this is damaged, it can draw more power than normal, which can then cause the circuit board to trip.

The easiest way to repair this is to replace the wash motor. To do it, you’ll need to turn off the electricity. Then, you can access the motor through the bottom of the dishwasher and drain all the water.

Once you’ve done that, please replace the motor.If you don’t feel comfortable doing this, please call a professional.

#5 Issues with Control Circuit Board

If you tried all the fixes above, but your dishwasher is still tripping the breaker, it’s likely that you’re dealing with is a faulty circuit board.

The circuit board is the computer that is responsible for all the functions of the dishwasher.

If your dishwasher is old, it’s common to have a faulty circuit board.

With a circuit board that is damaged, it is certainly going to be best to get it replaced rather than trying to repair it.

As long as the body of the dishwasher is still in good shape, I recommend calling a professional, so they can help you replace the circuit board.


That about covers it! Hopefully, with the help of the five fixes above, you’ll be able to stop your dishwasher from tripping the breaker.

Remember, you’ll need to use a regular plug and make sure the heating element and motor are working correctly.

Moreover, don’t forget to check the transient voltage suppressor and the circuit control board.
