Scott B Swampscott , MA December 15, 2019 Appliance: KitchenAid Undercounter Dishwasher KUDK03FTSS3 Kitchenaid Dishwasher Kudk03ftss3: Dishwasher was not cleaning the dishes properly. How to replace Circulation Motor. The first thing I checked was the food grinder to make sure it was not clogged and was still working. It was not obstructed and working properly so I narrowed it down to the motor and pump assembly. It was very easy to pull out the dishwasher and tip it up on its top to be able to get to the part. Make sure you have 1/4 inch drive set with a 6 inches extension because the one bolt that secures the motor is not easily accessible. It took about a half-hour to complete the repair. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
