Kitchenaid Dishwasher blows thermal fuse

5 posts in this topic

My dishwasher is 2 yr old and has blown out the thermal fuse again.  This started once out of warranty and has been replaced 3 times.  Obviously a bigger problem involved.  Model number is KUDR01TJBL1 (saw another post for a KUD01TJBL which needed an updated circuit board, not sure about this model though).

Any help is surely appreciated.

Doesn't seem to be much interest so let me ask some questions.  Everything is completely dead once the fuse is blown.  A new fuse has fixed the d/w for a couple of months.  It seems likely that its a short in the heating element.  Where should I start looking for the problem?

Hmmm, curious now b/c someone else has this problem.  The thermal fuse block is behind the control panel.  Just remove the top screws (inside the door) and the first few on each side near the top, also loosen the screws holding the panel on so you can slip the control panel off.  It's the white one inch peice of plastic with two wires coming in at each side.  It's molded with a small clip on it so it'll clip onto the black control panel (not the board).  Let me know if you want more detail b/c I'll have to take mine off anyway and can snap a photo for you if you'd like.

Hope this helps.  BTW, the first time, we were able to limp by for several months before it blew again.  The second time it only lasted about 5 weeks.  Also you can pull the part # directly off the part and goto  I looked locally but couldn't find anyone who had one in stock.  Guess they're not that popular.

Good luck,
