Hi all:

So I have an oddly burned out control board for my dishwasher. It failed during a wash cycle or right at the end, possibly at pump out, with a complete shutdown (no life in the panel) and a burning smell.

My hope was that it was just the bimetal fuse - which is in fact blown - but the damage to board was more extensive than I would have expected and leads me to believe that I may have a stalled pump or something else that will just burn out the replacement board.

Here is what the board looks like:

And here is a closeup without the connector:

As you can see the L1 PILOT connector got completely roasted and the whole connector will need to be replaced in addition to the fuse and board. I don't see how this line directly takes a load from the motor or other high volt area so I clearly don't understand the circuit - thus my fear that there is something worse going on that caused the overload.

Anyone seen something similar? What should I check before just blinding replacing everything and hope it doesn't blow again? Should I try to run the motor somehow directly or check for a stall some other way? Is it possible it was the heating element that shorted when it died (haven't tested the resistance in it yet, don't know if it's in the circuit)? What could it be?

Parts will be in Friday Jan 13 so any advice by then would be much appreciated!

Thanks
Mike

Looks like your too late though: The claims deadline for KitchenAid and Whirlpool-brand Dishwashers is now closed.

The last day for class members to postmark or submit claims for cash rebates for replacement dishwashers or for past overheating events is June 27, 2016.

It turns out if you call KitchenAid and use the keyword "fire" they'll transfer you to a special risk management department who will then arrange for a no-cost technical evaluation. They're coming tomorrow so I don't know what will be covered once they look at it but I figure if they're willing to cover the cost of a diagnostic visit they'll cover the repair if it fits the parameters of the original failure type. We'll see.
