Product review (1 stars): even the service person said they were bad units
Purchased at lowes. Delivery was prompt and setup was great. The unit worked fine for almost 1 week and then the troubles started. 1st service call the rinse aid tank/door was replaced. The 2nd call was to replace the same parts and a door gasket. The 3rd was to replace the "brain" as it would randomly pop on and wash with no one near it. Next the soap dispenser door fell off during the cycle. Then the leak started again. Fast forward to a week after the warranty ran out and the soap door falls off again, the rollers for the upper rack break off and it doesn't clean anything like it used to. Twice when the repair service came out I was told that most of the newer Kitchenaid units were problematic and they were often called out to work on them.

 I will limp this out until I have to replace it but after buying an $800.00 dishwasher and it spending over 90% of its life functioning well below 100% I know what brand I won't purchase.

Before looking for a new dishwasher I would recommend calling your local service company and just see if they will give a recommendation of what to get...or at least what not to get.

Update:3/12/13 (basically a year later) just over 2 yrs into the purchase and to add to it we have had to replace the upper rack adjusters (3 times), the rear slide adjuster and another gasket.  Time to replace. $800.00/2 years = 400/year. The last dishwasher I purchased cost $300.00. That was 9 years ago and it's still in that house, still working great. Too bad there are no negative stars.
