Product review (5 stars): I love it!
I have an earlier model and I feel compelled to write a review after reading many of the comments on here.  My DD603 is a 2002 purchase. I love it!!! There is a learning curve on how to load but once you figure it out, it is fantastic. One word of advice though, is to rotate your usage between drawers so one drawer doesn't wear out before the other. I do not treat my dishwasher like a garbage disposal and always rinse my dishes before placing in the dishwasher. Secondly, once a quarter, I dump a gallon of vinegar in the washer and run it on hot. I live in Houston where hard water is an issue. The vinegar cleans the appliance beautifully. I dread the day when it no longer works!  This is my favorite appliance and I own a Subzero fridge and Dacor ovens and cooktop.
