I discovered a major leak at the bottom of the dishwasher near the diverter motor. The leak was so significant that water dripped onto my basement floor. The dishwasher is 7 years old. I read a number of articles suggesting that the problem would be the gasket on the diverter motor. I ordered one and that wasn’t the problem. I removed the dishwasher from the cabinet and disassembled the sump and motor assembly. After doing so I could clearly see that the leak was coming from the sealed gasket that goes around the assembly and attaches to the inside of the dishwasher. I probably could have just purchased the sump assembly without the drain and diverter motor and saved around $200. Since the dishwasher was 7 years old and I had it apart I decided to replace everything. It came assembled as one unit. That being said I didn't need the special sized clamps that I ordered for the drain motor. I paid for next-day shipping and I received the part the next day and completed the repair. I really can’t see a way to make this repair without removing the unit from the cabinet space. There are 3 sump mount bolts that need to be removed as well as a number of electrical connections and a few of these connections weren’t visible until the unit was removed and flipped onto its back. As most people have stated the hardest part of the repair was removing the dishwasher from the cabinet space.
