Question about Whirlpool 24 in. GU1200XT Built-in Dishwasher

4 Answers

Whirlpool Dishwasher No Power: GU1200XT dishwasher thermal fuse in power up circuit blew & was replaced about two months ago. It has blown again. Both times it was after wash was finished but water was left in tub. Would appreciate suggestions on what may be causing the hi temp condition and how to verify.

    OK. Didn't see any obvious problem with wiring harness or connectors. Would it be worth replacing wiring harness first?

  • asander Sep 22, 2009

    Thank you. The wiring was not replaced--just the fuse in the plastic piece. Wouldn't the original problem that caused the fuse to blow still exist even with the fuse replaced properly? Mine isn't included in the recall.

Hi,

The thermal fuse protects the entire dishwasher circuit from overload. Not just the heater or motor, but everything. From the diagram in the tech sheet, you can see that this fuse is between the incoming line voltage and the door switch. This means it is controlling all power to the dishwasher. Any shorted component can open the fuse

You will get two new wires with the fuse kit.
You need to make sure you use the new wires in the kit with the new fuse.The old wires have a bad connection that create heat and blow the old fuse

If the tech who replaced the thermal fuse didn't replace the wiring that came with the new thermal that could be the problem,there was also a recall on certain models because the motor was getting too hot,you may want to check and see if yours was one of those. copy and paste the web link to see if yours may be included.But if you called Whirlpool when you need service they should have caught it.

    The thermal comes with two wires about four inches long with screw in terminals the wires are usually yellow if you don't have this then ask for a different company next time. check out this picture and see if it looks familiar.

Sometimes a wiring problem that happens only occasionally can blow the fuse. Have a look at connectors and wiring harness.Disconnect power first.
If the fuse in control panel keeps blowing, next step is replacing the electronic control (CNTRL-ELEC (USE WPL 8564543).

I have a Whirlpool ADP9000ix diswasher that will not power the front display/touch panel. Therefore cannot turn the dishwasher on. I have checked the circuit control panel. And power is getting to it....

If your Whirlpools over there are like the older ones here in the U.S., you may find that there is a thermal fuse mounted just above the circuit board. If there is one, turn off the power to the unit, pull off the 2 wires connected to it and check it for continuity with a multimeter. If that fuse is blown, nothing works as it controls all power to the unit. Replacement fuse kits (at least here in the U.S.) are readily available on ebay for a fraction of the price that an appliance parts store would want. By looking on ebay for "Whirlpool dishwasher fuse" you can see what the fuse assembly looks like, and if identical to yours, purchase one. If you do buy one, follow the installation instructions exactly by using the supplied wires on the new fuse and the screw terminal block to make the connections. If you don't use the new wiring and connection block and simply plug the new fuse to the old connectors, it will simply blow again in a short time.

No power. Will not turn on

It may have tripped the internal breaker, and or the house circuit breaker. Go tot the house fuse box and check that first.

Why thermal fuse is blown

If you have no power to your machine and the power is on it is the thermal fuse. If the fuse is blown you will get no power at all. To my understanding after talking to many people the thermal fuse is likely the first thing to go bad on a whirlpool dishwasher. A power surge to your unit would cause the fuse to blow or the control board to go bad.

Why isnt my dishwasher powering up

assuming the power circuit breaker is ok and you are getting power to the dishwasher itself, there are other factors that could lead to an outcome of dishwasher not appearing to be powering up.
The most likely cause is power supply inside dishwasher is faulty, the controller is faulty or simply the dishwasher display panel is faulty.
More likely the dishwasher has suffered a "thermal" trip. The thermal fuse located in the control panel on the door has blown. You may need to replace it. It is item 6 on this diagram

My 2yr old whirlpool dishwasher model# DU1145XTPBA, ser# FU3026019, 2.7 amps, type# 5750-0 has stopped turning on. I never had any trouble out of it and now it won't turn on. I thought maybe a fuse...

It is possible the thermal fuse located in the control panel has blown.
See item 5 in this diagram. You could attempt to replace it.

make sure the power is disconnected when you are working on the dishwasher.

Hope this helps.

Whirlpool Dishwasher acting as if there is no power to it

I had this problem just two days ago. For me it was the thermal fuse. On my dishwasher it is located on the main control board, at the top. It is white and has two wires going into to separate terminals. It says "Microtemp" on it. I used a small wire to short it and see if that was the case. Be careful though. There is also another fuse on the bottom of the dishwasher that looks like a little black cylinder with a silver cap, and two terminals coming out of it for wires. In our case that fuse was fine.
