Good Afternoon,
Thank you to everyone who gives your time & effort to run this site. You have previously helped me with repairs to my 25 year old Kenmore direct drive Washing Machine. It still runs great!

My Whirlpool Dishwasher Thermal Fuse blew. The dishes were clean & water was left in the bottom of the tub. Air dry is selected. I installed a new Thermal Fuse & ran a cycle. The fuse blew & left water in the bottom of the tub again.

I removed the dishwasher from the counter & examined all wires & connections in the door & under the unit. All connections were solid and no wires seemed brittle. No insulation was off of the wires.

I hooked up the dishwasher to run in the open. I jumped the fuse and sat with the dishwasher while it ran through a cycle. The water temperature was 110. It ran full cycle without any problems.

What procedures do I need to follow to determine what the issue is?
Thank you so much for your help.

Hi,

Thanks, we love to hear that.(y)

For the thermal fuse in the control panel, did you also install the new wiring that came with the new thermal fuse? If not, that's why it keeps blowing out.

Thermal Fuse 675813


Here's the video that shows you how:



Let us know how it goes.

I did not install the new wires. The old wires were both pliable and did not test with any extra resistance. I will replace the wires and try a new fuse. Is there a reason that the fuse would blow out at that same point in the wash cycle both times?
Thank you.

Not that I'm aware of, all I know is these wires that come with it have to be installed or it will keep blowing that thermal fuse out.

Jake, Once again, you are 100% correct. The long wire was easy to replace. The short wire in the multiple wire connection plug would not come out. (Watched video, worked 90 minutes, used different sized paperclips...) I ended up cutting the short wire 1 inch from the plug and solder splicing the new short wire into place. I just ran a full cycle. The tub emptied and the fuse did not blow. (It is strange that these 2 wires would inhibit the repair of the dishwasher. Also, the replacement wires were a larger gauge wire than what came with the dishwasher. It would seem that these smaller wire would enable the fuse to blow more often.) Please mark as repaired.
 
Excellent Sabot, good job.(y)

Thanks for the update!

Jake
