Dennis W Manhattan Beach , CA July 11, 2023 Appliance: KitchenAid Undercounter Dishwasher KUDI02IRBS2 Kitchenaid Dishwasher Kudi02irbs2: Whining noise during wash cycle drain cycle normal. How to replace Circulation Motor. First I tried diagnosing the problem by reading the forum stories. I had previously replaced the chopper unit so it had to be the circulation motor. Then I watched the video specific to replacing the motor and decided I had the tools and know-how to complete the repair. I ordered the motor that arrived the next day (California). Not mentioned in the video was to be sure to remove the baseboard plates and retract the leveling legs in the front in order to extract the unit from the cabinet. Also, there is plenty of residual water in the sump, so get towels. The video clearly detailed changing out the motor, which was the easiest part of the process. The dishwasher is 16+ years old and now runs like new. Do-It-Yourself Rating: Repair Time Estimate: 2+ hours
