My Kitchen Aid Dishwasher has been down for a couple years because I'm too stingy to pay the OUTRAGEOUS prices for parts locally and on the web. It is a high end unit.
We'll, recently, Mrs T finally emerged from the crawlspace through all the KFC buckets and pizza boxes, She demanded I fix it.
I found this http://www.partselect.com/. I Picked the parts (which was basically everything) and rebuilt the dishwasher. This dishwasher is locked under a granite countertop, and trust me, it ain't coming out.
I was out the door for under $200 with shipping. I basically replaced every moving part and rubber.
They even have links to repair instruction videos.
Fix it yourself with http://www.partselect.com/
I'm not affiliated with this outfit in any way.
