Product review (3 stars): These dish drawers are very nice for a couple but seem too inefficient/small for a ...
I'm starting this review over as we had a DD-603 (2003 model).  Now we bought a used DD24DCTX6V2 (2011), very similar to the one being sold here.  First, the whole inside of both drawers had a thick white scum. This is from using way too much detergent. We only fill the large detergent side 1/2 full or less, none in the smaller pre-wash side. So we scrubbed this used machine as clean as possible and then let it start washing and poured in white vinegar. Ran it several cycles with vinegar. This machine was given up on because the lower drawer would not empty. This was because the lower rotor was missing petals on the lower part which is the water pump. The part is $79. We have ordered the new rotor and expect it next week. The machine is very quiet and has lots of features. Our Family room shares space with the Kitchen and right now, the upper drawer is running. It's just a light hum as it merely cleans our dishes. So here's another must-do. We rinse of our dishes before putting them in the dish drawer. These machines get light soil off of the dishes but in no way can handle lots of food debris. We had an old KitchenAid that would grind up food.  We could take any bones off the plates and throw in the dishes as-is. This is not possible with the Fisher & Paykel.  The machine will die early. The only design issue I can see with these machines is the lid. The lid motors lower the lid over each tub before washing starts. If one lid motor fails, then the machine will leak. This will eventually post an "F1" error code (leak). The detergent in the leaked water can do lots of damage such as take out a lower lid motor if it was the upper drawer that leaked in the first place. It can also destroy the power distribution board in the bottom of the machine. So what F&P should have done is had optical or mechanical limit sensors that make sure the lids are really closed. As it is, it's a bad design. If you buy one of these, you must have a good mechanical background so you can fix it yourself. They cost too much to have repaired. We are opposite to many here. We are on our 2nd F&P Dish Drawer and our 3rd F&P Washer and Dryer.
