I have a KitchenAid KUDP01ILBS6 dishwasher that blew it's thermal fuse.

I replaced the fuse and wire harness with this one:
8193762 Dishwasher Fuse Kit


I also too everything apart around the lower spray arm (not sure what it's all called, but there was some sort of macerator and a few filters) and found some broken glass and other debris I thought might be jamming something.

The new fuse lasted for close to one cycle before blowing again.

Any idea on what's happening? I've read it could be loose wires. Is the next step to check each connection?

That thermal fuse can only blow with too much heat build-up.

Did you hear the water splashing in the tub when the pump was running? Was the heating element extremely hot?

Oh, that's interesting.

I know it's called a thermal fuse, but thought it was measuring temperature generated by current in the wire it was attached to. It didn't make much sense...

Anyhow, for clarity; this is a fuse that's located behind the panel at the top of the door, which seems like a strange place to measure temperature. Does it get really hot in there?

I didn't listen to whether the water was splashing and didn't do anything to assess how hot the heating element was.

Maybe I'll throw another fuse in and pay more attention?

Yes it does.

When you opened the door was it extremely hot inside?

I didn't notice if it was extremely hot inside. There was no lava, for sure, so we know it wasn't that hot.
I think I'll get another fuse, make sure it's installed correctly (I remember the new harness installation being kind of weird) and try it again. I'll stop it if it sounds like there's no splashing when the pump is running or if it seems to be getting hot.

Yes, exactly.

I replaced the fuse and ran a 'normal' cycle. The arms are spinning around (I can see that when I open the door and I can hear splashing) but I'm not sure if it's too hot or not. A bunch of steam comes out when I open the door and it seems pretty hot, but I don't know if it's too hot. Any other suggestions?

 

[sinepsnatas]

So, I think we've eliminated the arms not spinning as an overheat cause. Is there a reason the heating element would be too hot (if that's what's wrong).

 

[Jake]

If the heating element is staying ON at all times.

If not, you'd need to replace that control board too.

Here's the control board for your model: WP8564543

Buts its been discontinued. 🙁

Probably time to dishwasher shopping.
