Product review (5 stars): Good thermostat that fit perfectly. NOTE - Tip in review to explain RESETTING Your Dishwasher Control Panel
Purchased & swapped out the one in my dishwasher after the element burned out thinking this might be the problem... I was wrong! BUT that was my fault.

This part works perfectly and I have since found out that if your element burns out the control board can essentially 'shut down'. Maybe this is to protect the board... or maybe this is to protect the Whirlpool repairman's bank account - dunno!

So... if your dishwasher burned out the element or you replaced this and it still doesn't heat the water or dry the dishes then TRY THIS (it's free!):

On some new model dishwashers after the heating element has burnt out you must perform a control board 'reset' to get the heater to turn back on. See the picture with this review. Basically you look at your control panel and select the first three buttons starting at the left before 'Start/Run'. In my case this is the 'Select Cycle' (1), 'Select Heat' (2) & 'Select Timer' (3) functions. (Your dishwasher may have a different panel.)

Press the buttons quickly in order 1,2,3, 1,2,3, 1,2,3 . You should see the panel lights come on together (or most of them) after which the unit will begin a short 'test & reset' run that takes about ten minutes. When that cycle is complete and the unit is finished... pop open the door and you should feel the heat escaping from the element! (Don't grab it... ok? Just enjoy that waft of steamy heat and dishwashery goodness!)
