Product review (1 stars): Buyer Beware
I recently purchased a Kitchenaid dishwasher to replace a Kitchenaid that operated faithfully and problem-free for over 15 years.  The plastic covering on the inside of the door rotted out, so I decided to replace it with a new Kitchenaid, the KUDS30IX6TI.

What a mistake!

The man who installed it had years of experience installing dishwashers.  He installed the drain in exactly the same fashion as the previous machine, since it worked well for 15 years.

When I used the new unit, it made so much noise I thought it was haunted.  And the cycles lasted for two to three hours.  Finally, after 8 months of strange noises and super-long cycles, I called for warranty service.  Technician from Dan Marc diagnosed the problem without even pulling out the unit to see how it was setup to drain.  He said it was installed improperly and that there was no loop to break the vacuum and the machine was draining prematurely.  End of story, and out the door he walks--said he couldn't do a thing if it was installed improperly.

Back on the phone to Kitchenaid and the scheduling of another warranty inspection from another company.  I pulled the machine out before he came and discovered that Kitchenaid has a loop (which is what the tech said I needed in the first instance).  This tech said that I had to have another loop and an air or vacuum break in the line besides the loop supplied by the factory.  Said he couldn't do a thing for me because it was installed improperly.  Out the door after telling me I would be billed for the call--even though the machine is still under warranty.

Lessons Learned:
Never again buy a Kitchenaid appliance.
If you must,make sure the installer is aware of the myriad of hoses he must install and the Rube Goldberg way in which he must install them.
Read the warranty before you buy.
To reiterate, never again buy a Kitchenaid appliance.
