Product review (1 stars): An Expensive Lesson
We bought this Kitchenaid dishwasher 11 months ago and it suddenly started to leak from the bottom.  Quite a bit of water got into the sub-flooring before we realized what was happening.  Some damage was done to the downstairs ceiling (water stains, soft spots, etc.)  Water also got into one of the light sockets and the bulb started sparking so we shut off the power to the area due to fire concerns.  Later, we noticed some water had seeped onto a shelving unit doing some damage to the items stored there.

After we shut off the water and power to the damaged areas, I removed the kick plate from the bottom of the Kitchenaid and had a look with a flashlight.  There was no leakage coming from the install points (water supply and drainage hoses) which told me this was not an installation problem.  However, I noticed squeeze type pressure clamps on two of the dishwasher's connection hoses.  These are not the types of clamps (in my opinion) that should be used where water is involved.  I would use quality clamps where the pressure could be set with a screwdriver.  I also noticed a part of the dishwasher (motor or pump I thought) sitting on the floor apparently detached.  It looks like this dishwasher may have some design flaws but clearly there have been some cheap parts used in its construction.  I was quite shocked.

Whirlpool was very supportive and apologetic on the phone but said we would still have to wait 2 weeks for service.  Because of our concerns about the poor build quality of this unit, we've decided to take the next 2 weeks while waiting for service (and doing dishes the old fashioned way) to look for a better machine.

Our biggest question right now is once the dishwasher is "fixed", will we be able to trust it?  What if it leaks again and we aren't home?  Being able to sleep at night is more important than the $1,000 or so we spent so we will consider this (and the cost to repair the damage to our home) the cost of tuition to learn about Whirlpool / Kitchenaid.  A lesson learned, albeit an expensive one.

Update - the service technician finally showed up today.  Here is his report - "11/27/13 11:30: RN there 27 WED, 11:07 to 11:25, Checked over unit.found clamp came off the motor and wet the motor shorting motor and control.ordered parts from marcone., ordrd 1 w10328224 (sump and motor assy) and 1 w10473198 (control), saved tckt [SdLink\'46491a.png] (via SDM)"  I asked him about the clamp coming off and he said it was a "common problem".  We are now waiting 10 business days for the new motor and control (and hopefully a better clamp?).  When it's back up and running, we'd like to sell it.  Anyone want to buy a 1-year old refurbished Kitchenaid dishwasher that couldn't possibly leak again?

Final Update - Decided to see if the dealer would help and sure enough they did.  We worked out a deal to our satisfaction and have just installed a new Miele Crystal.  I was impressed with the German engineering and the specs.  The Kitchenaid is gone so the bad news is it's not available for sale but the good news is we have peace of mind.
