People who own a dishwasher may experience a blown thermal fuse at some point in their lives. Replacing it is a fairly straightforward process, and it isn’t unusual. What happens if the thermal fuse keeps blowing again and again? If that is the case, you might have a problem elsewhere in the appliance.

A broken wire, a problem with the wire harness, loose electrical connections, and a faulty temperature sensor are some of the issues that can cause your dishwasher to blow the thermal fuse. We are going to investigate the very common question “Why Does My Dishwasher Keeps Blowing The Fuse?” 

I keep blowing fuses in my dishwasher. Why is that?

There are loose wiring, faulty switches, and obstructions that can cause the dishwasher to blow the fuses. The above points can cause electricity tripping or blowing off of the fuses in the dishwasher.

Water leaks

Water leaking from the dishwasher is one of the most common reasons for the dishwasher to blow its fuses. The dishwasher tends to have problems due to the dampness in it. The leaking water will start to trip electricity if it reaches the motor of the dishwater.

Faulty Components

The faulty component is the most common problem that causes a dishwasher to blow off the fuses. There are faulty components that include damaged switches, motors, Suppressors, and heating devices. It can be the source of the problem in the dishwasher.


The jam in the outlet of the dishwasher could be one of the reasons for the tripping of the electricity.

Wire Harness

Some manufacturers will recommend changing the wire harness as well when replacing the thermal fuse. A wire harness is a bundle of wires that are used inside a dishwasher.

Think of it as a complete set of wires designed to fit your dishwasher perfectly. Rather than trying to inspect and fix individual wires, wire harnesses make it much more convenient to replace the whole set of wires.

If you have changed the thermal fuse more than once, some manufacturers recommend changing the wire harness. Again, this is the same thing, be sure to remove the dishwasher from the power supply and drain the water inside.

You can access the panel’s wire harness from the side of the panel and then remove it. Then you can connect the new wire harness to where the old one was. This way you don’t have to reconnect the connectors when everything has been installed.

Before you get started, it will be important to make sure you have the right tools to remove the old wiring from the vehicle. If there are no printed materials available to guide you, it will be necessary to take photographs of the old wiring harness to help you determine how it was installed.

With any sort of electrical installation, getting your work done is only half the battle; making sure you have a good working electrical system at the end is what it’s all about. This is why it is essential to use proper wiring methods and know-how to properly install your new wiring.

Loose Connection

Dishwashers have a lot of electrical wires inside that connect their components. Those electrical connections mustn’t be loose.

The dishwasher needs to be able to deliver power to each component at the correct stage in the washing cycle. To prevent problems like short circuits or excessive heat, those connections must be put on tight and the electrical current must flow through without any restrictions.

The wires only make contact part of the time because of the loose connection inside the dishwasher. That can lead to an increase in the circuit’s amperage, and that will eventually cause the thermal fuse to explode.

What Causes The Thermal Fuse On The Dishwasher To Blow?

Loose wiring, overheating of the metal ribbon, and overloading are some of the reasons why the thermal fuse can blow on a dishwasher. Most of the electrical appliances are powered by a thermal switch. 

It is possible to protect the devices from heat damage by cutting down the connection to extreme temperatures. Here are the possible reasons behind thermal fuse blowing in a dishwasher:

Loose contacts

A loose connection between the wires and the plug sockets in the dishwasher can cause the thermal fuses to blow off. Sometimes the primary system wires don’t get access to electricity properly due to loose sockets or wires.


The overheating of the dishwasher is one of the most common reasons behind the melting down of the thermal fuse metal ribbon. There could be a case of one or two main system wires touching the neutral or grounding wire. This causes the system to get heated and causes the metal ribbon in the thermal fuse to melt.


When the dishwasher gets a lot of loads, the thermal fuse in the dishwasher will melt and refuse to work. If the dishwasher has too many lights on at the same time, the heat will melt down the thermal fuse metal ribbon.

The Dishwasher Blows A Fuse At The End Of The Cycle

When the dishwasher blows a fuse at the end of the cycle, do you not feel upset? The dishwasher short circuit is the most likely cause of such an accident.

The dishwasher has a metal string that stays connected when the machine isn’t operating. If the dishwasher gets overheated due to a short circuit, the ribbon will melt in the case and blow a fuse away.

At the beginning of the wash cycle and the end of the wash cycle, the system has a minimum and maximum temperature. Sometimes the fault in the dishwasher causes it to gain the final last round temperature at the beginning of the process which causes the system to get extremely heated. As a result, the power goes out.

Here are a few ways to fix the dishwasher fuse blow at the end of the cycle:

If the dishwasher has got some loose connection, you can apply some pressure on the plug or wall sockets. It is possible to check the doorknob of the dishwasher to see if it is fixed during the last part of the cycle. 

It’s a good idea to give the plug wires in the dishwasher a checkup now and then to make sure they don’t get damaged. The thermal switches need to be checked immediately by observing the multimeter. You can call for a service member to fix the dishwasher’s problem.

What Is The Best Way To Test A Dishwasher Fuse?

The most common problem which people face with their dishwasher is not being able to test whether the fuse is blown or still working. Here you will find out how to test a fuse manually or digitally, the safety tips you need to take while testing it, and most importantly, the fix of the problem.

If you read the manual, you should be able to figure out whether a fuse has blown off by watching the needle. When it moves, the fuse is blown. If the needle remains still, it means that the fuse is not blown.

You can also check if the fuse of the dishwasher is blown by merely using a voltmeter. It is a good idea to take a digital or analog voltmeter. To make the readings on the resistance dial zero, in the beginning, you have to use both of the voltmeters. 

It’s important to make sure that the device’s fuse has been removed. It is not a good idea to use a voltmeter on the dishwasher’s electrical system. Attach the probes of the voltmeter to the ends of the transformer. 

If the needle shows movement till zero on the attachment, then you can be certain that the fuse hasn’t blown yet. If the needle doesn’t show any movement or reflection, then it’s time to blow the fuse.

You can fix it by removing the glass case and taking out the melted wire if it is a thermal fuse. It’s possible to put in a fresh metal wire inside the thermal fuse to make it work again.

What Can I Do To Stop My Dishwasher From Blowing Fuses?

Do you have a problem with the electricity in your dishwasher? If yes, you shouldn’t worry as the following tips might work for you.
