Thermal Fuse malfunction frequent occurrence. Dishwasher worked for a couple of weeks after purchase then the Thermal Fuse blew. Replaced it and that fuse worked for a couple of weeks then blew. Replaced that fuse with but didn't direct wire dishwasher to the house opting for a plug and used without problems for a few months thinking we had a good fuse directed wired the washer to the house. Thermal fuse blew after a couple of washes. The previous dishwasher blew it's thermal fuse it was a maytag which was recalled due to a problem with the rinse agent leaking into the wiring. Now either we have the worse luck purchasing bad new dishwashers or something is possibly wrong with our household wiring and circuit breaker.

Shouldn't the circuit breaker trip before a Thermal fuse would be needed? And couldn't the problem be in the house wiring and the circuit breaker not the dishwasher itself? Should we bring in an electrician to change out the house hold wiring and circuit breaker to the dishwasher? The house is 32 years old and the wiring hasn't been updated since construction.

First off we are unpaid technicians offering free advice on our time to help you out. If you have not received a response it may be that we are unsure of the cause of the problem and don't want to give out wrong advice or information. My question to you is this. If you just purchased the dishwasher and the thermal fuse is blowing, why are you repairing it as it should be under manufacturers warranty. I would have called for service while it was under warranty.

Did call them they still charge you a $85 service fee. And they did replace the fuse twice. I am just frustrated at the inconvenience and expense. I simply think that my house breaker should flip off before a thermal fuse would trip. Or has whirlpool and other manufactures made thermal fuses so sensitive that they trip way too easily.

Dishwasher is out of warranty and I am still having the same problem. I can't afford to replace a dishwashers every year and half and pay for a bunch of service calls. Considering this is the 2nd dishwasher which has had thermal fuse problems.

I would check the amperage that the circut breaker is drawing without the dishwasher running . Example if you have 15 amp breaker and its drawing 12 amps before you run the dishwasher the fuse would blow first to protect the dishwasher . In most older house's wiring is sometimes inadequet for newer appliances.Here are some easy ways to find out how much amps you are drawing.

1. Shut the circut breaker

2. Make a list of all appliances that are on that line fridge toaster what ever .
3.Check your manufactures specks on their amp draw these are listed in your owners manual for these appliances.

Hope this helps you out
