I have done two repairs, and both times PartSelect.com came to the rescue! The first repair was a few years ago when the dishwasher would run but nothing got wet. It made all the right noises except the sound of water being thrown around, because no water was being pumped! This resulted from a cheap plastic "chopper" assembly that stripped and wouldn't drive the impeller. PartSelect sold me a solid metal replacement part for under $10 and that fixed the problem for several years.

Recently, we had a different problem where the dishwasher completely haulted and the wash motor wouldn't run. This was caused by a faulty impeller, another cheap plastic part. The wash impeller fragmented around the drive shaft to where it sat uneven and thus created too much resistance for the motor to drive it. I removed the impeller, superglued the plastic parts together so that I could then wrap them in copper wire (about 1mm diameter), and then I hot-glued over the copper wrapping to secure the entire thing and to help keep water out of it. I did this so that we could wash dishes while we waited for the new impeller. Well the new impeller came several days early and so far I have just been too lazy to go remove the makeshift part. I figure it will fail sooner or later and then I will install my new part which should give me at least 9 more years of trouble free washing!
