Product review (1 stars): Absolutely horrible dishwasher
Absolutely horrible dishwasher.  We replaced it with a new LG unit after 1 1/2 years of usage.  After spending $1400 for the KitchenAid dishwasher, I was surprised as to how low quality it (and probably all other KitchenAid dishwashers) was built.  The first part that went bad, around a year into using the dishwasher was the upper rack posts that support the rolling wheels started breaking 1 by 1.  I looked at it and the post itself was made from cheap plastic, whereas all other dishwashers I looked at when got the replacement dishwasher had a metal post there, hence no breakage.  Once it breaks, Sears and all other suppliers I found on the net charge at lease $30 for the part.  Having 4 roller posts on the upper rack, be prepared to spend $120 to replace the parts (this is if you are a handyman and actually know how to replace the part).  I'm pretty handy but I could not figure out how to remove the broken post contraction from the rack, so I just used my own screws and washers to build a new support contraption for the upper rack.  It did not roll, but at lease we can wash dishes once again.  Then right after this happened, the computer circuit board went bad and the wash cycles did not drain at all.  We ended up having to do 2 cycles per load, the first load washes with soap, then manually called the drain cycle, and run a second wash cycle with no soap to rinse the dishes.  Maybe this is a lemon unit per for circuit board, but the construction of the rack posts and the price they charge for replacement gives me every indication there is no quality built into in these dishwashers at all.  They probably count on these parts breaking so people will have to pay an arm and a leg for replacements for profitability.  Before you buy these and any other KitchenAid units, make sure to take a close look at how they are built and compare to other dishwashers.
