I recently bought a Kitchenaid KDC21A dishwasher from someone doing a remodel. I had had one in the past and liked it better than the newer Kitchenaid dishwasher I had used for the past ten years. I was told it worked, but when I got it home, it wouldn't do anything. I found this site and read what stevet wrote to someone with a similar problem about the little tab on the upper corner of the tub that activates the door interlock. I looked tonight and there wasn't one on the machine I had. Using his instructions, we figured out that was why it wasn't working. I haven't tried rigging up the 6/32 screw yet, but that's the next step since I don't have the part. I am also missing the brackets and whatever else held the machine to the underside of the countertop. Can someone tell me what works best to replace those connectors?
