Question about Whirlpool DU943PWK - Multiple Color Built-in Dishwasher

Open Question

We have a Whirlpool DU943PWKT0 dishwasher which continues to blow the 'thermal fuse' periodically.

I have a previous post about this unit where a solution, i.e. replace thermal fuse fixed the situation. Now some 3/4 weeks later the unit has stopped again and it appears it is the thermal fuse again. We've used this unit in the same location for over a year now and 'why' would this unit begin to toast thermal fuses, given this is the current problem. I will follow up after finding time to inspect the unit again, but I'll bet it is the fuse again as the unit is stone cold dead in mid cycle as last time with the bottom standing full of water. It appears to go kaput during the rinse cycle... Thanks

It sounds like the thermal fuse in the control console has blown.
Turn power off to unit.
Remove the outer door panel and then the console.
Remove the black plastic cover from over the circuit board if it has one.
You should see the thermal fuse clipped to the circuit board housing.
If you have an ohm meter, check for continuity across it, it should read closed.
If you don't have a meter, unplug the wires from it and and hook them together.
Turn power back on to unit, hold door switches down and cancel cycle. The washer should drain the water.
If this doesn't work, check your door switches to make sure they are closing properly.

SOURCE: Dishwasher will not drain

Hello Tom,
Glad that you were able to find something out of place in the check valve ( like the gasket) which in turn was restricting the ball in that check valve from being in the right position. I'd be willing to bet that your problem is solved..
Regards,
Rick

SOURCE: Standing water in bottom of dishwasher...didn't drain.

hit the cancel drain cycle. Often times the dishwasher drain hose is not installed properly. It must be routed up as high as the dishwasher as soon as it comes out of the unit. May be also that there was a little regular soap or something that made it sudds up. vegetable oil poured into the dw tub will remove the sudds. Try to wash again after cleaning out the sudds and run it again. Thanks

SOURCE: My Whirlpool GU2400XTP dishwasher keeps blowing

Are you replacing the wires along with the fuse? It is important to change the wires too as they are usually the cause for the fuse blowing. Be sure and get the fuse kit that includes the wires.

Is your water too hot? Hot water is fine but too hot of water can cause the fuse to blow over time. The temp should be somewhere around 120 F. Anything over 130 F is way too hot. I personally don't use a long high steam final rinse or high heat because over time the steam and cause the electronics to short as steam and moisture can get into the keyboard and inside panel.

Whirlpool Point Voyager Dishwasher blows thermal fuse - pump motor draws 10A


Yes 10amp seems a lot of current being drawn by the pump motor. Not sure if it is safe to run dishwasher in this condition. One reason could be a leaky capacitor on the motor. Try to replace it. See item 26 on http://www.searspartsdirect.com/partsdirect/part-model/Whirlpool-Parts/Dishwasher-Parts/Model-GU1500XTLB0/1198/0130000/W0503069/00008

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.

Nothing will start and no lights are on and water won't drain from bottom on dishwasher.


Hello, welcome to FixYa.

I understand by reading your post which indicates it is a Whirlpool
dishwasher model #DU1055XTPS you appear to have a concern with no lights/power to the control, correct ?

The one thing I'd suggest is the thermal fuse, typically the symptom you've described is associated with a bad thermal fuse. (part #
W10258275).

Here's a helpful link below to a video from "repairclinic.com" to assist in changing (or simply checking it as shown in the second link) the fuse kit...it generalizes on most Whirlpool built dishwasher's such as yours, but if slightly different it is essentially the same.

Most Whirlpool manufactured dishwashers have a thermal fuse, located inside the operator console. When tripped, the dishwasher will not run. A power outage can cause the thermal fuse to trip. It cannot be reset and has to be replaced, if bad. Please post back with your COMPLETE MODEL NUMBER (located around the door opening) so I can determine the configuration of your dishwasher and explain how to access any potential fuses. -->

I have a Whirlpool Quiet Partner 3. It sat up for a few months because the control panel went out and it took a while to save up and order a new one. Now it blew the thermal fuse. I put a 15amp...


A 15amp automotive fuse is rated for a 12VDC system in an automobile, not a 125VAC houshold electrical system in an appliance. I don't think your automotive fuse can handle the start current being drawn by the main wash pump as the dishwasher starts. I would recommend you replace the thermal fuse in the dishwasher with an appropriate replacement BEFORE assuming you have a problem with anything else in the dishwasher.


Some Whirlppol manufactured dishwashers had a noted problem with the thermal fuse. The gauge wire used in the control panel would heat up and cause the thermal fuse to blow prematurely. The manufacture's answer was to provide a replacement kit that you were to splice in place that had a larger gauge wire. The thermal fuse replacement kit for Whirlpool dishwashers can be purchased at any of the following websites:

searspartsdirect.com
pcappliancerepair.com
appliancepartspros.com
repairclinic.com

The thermal fuse should be listed under the "Control Panel" parts listing. The average cost is usually about $15 or less.

If you have questions, please post back with your MODEL NUMBER and let me know.

Hi,

If you have power going to the dishwasher, meaning the breaker, switches, wiring and fuses in the home are okay, the most common cause for your symptoms is the thermal fuse.

The thermal fuse is a small disk shaped device that is behind the control panel on the right side it is snapped on to the electronic module. The part number for your model is W10258275

I have a kenmore elite dishwasher model#665. no power


Nearly all Kenmore dishwashers have a thermal fuse inside the operator console. If the fuse blows, it will exhibit the symptoms you describe. If you post back with a COMPLETE model number (located around the tub opening with the door open), I can verify, provide you with a part number, and explain to steps required to replace it.

NOTE: "665" is the manufacturer code, which identifies the manufacturer of your dishwasher as Whirlpool.

Power to dishwasher but no power to panel


Open your console and check the continuity of the thermal fuse (clipped to the electronic control unit [ECU]).
Post your model number if you're still having problems and I'll try to assist you further.
Good luck!
