Product review (4 stars): Perfect Fix for Old Kitchenaid
Our Kitchenaid dishwasher has been giving trouble for a couple of months (clean light blinks 7 times and you can't run a cycle until you reset the controller).  Internet research indicated it was a likely heating element problem.  That fit since it often wouldn't run the drying cycle at the end and the dishes would come out clean, but cold and damp.  With a little more research, I figured out this was the correct replacement part.  Originally thought of just replacing the heating element, but saw several postings saying the controller and element should be replaced together.

Replacement took a bit more than an hour. I ohmed out the heating element. Not clear it was bad.  It had a resistance of 13.5 ohms; open or short indicate bad, from what I could read.  But after I replaced the element and controller, it works like new.  Maybe it was actually the controller that was bad.

Primary improvement would be if it included some basic instructions, particularly for accessing/replacing these parts.  I found some advice on the Internet, but I did some unnecessary fussing around figuring it out.  It did include a basic schematic, which could be useful for troubleshooting, but it worked perfectly when I fired it up.
