Product review (1 stars): Kitchenaid - REALLY  Glad I bought the EXTENDED Warranty from abt electronics
I purchased my kitchenaid dishwasher in July of 2012. At first it was really great. Cleaned well and most importantly was VERY Quiet.
However, after about 7 months the wheels in the upper rack disintegrated; replaced under warranty. After another 7 months (now out of factory warranty) the same problem occurred. (Replaced under extended warranty.) The service rep at abt said this is a known problem!  Most recently the soap dispenser stopped accepting rinse fluid and the soap dispenser would open immediately upon starting instead of opening in a delayed manner. Needed a new electronic mother board and a new dispenser, again covered under the extended warranty.
I have owned this dishwasher for 19 months and have THREE Significant service calls.
Make your own judgement on this unit...but make sure you buy the extended warranty if you do purchase.
