Bought Maytag Quiet Series 300 at Home Depot. Worked okay (takes MUCH more time to go through the cycle than others I've had) but in the past 2 months it hasn't been washing all the dishes. The dishes on top and bottom rack in the FRONT are not clean. The back seems to be clean. I've tried everything, short of calling a repair man. And of course the warranty expired 3 months ago... ironic timing.
