Judy C Prescott , AZ November 04, 2019 Appliance: Whirlpool Undercounter Dishwasher DU1101XTPBA Whirlpool Dishwasher Du1101xtpba: Our appliance filled with water but was not spraying, it made a buzzing noise. How to replace Circulation Motor. We cleared debris and when that did not work we replaced the pump. The hardest part was finding the correct sized socket set. The video had a different size than what we needed. Extender required on the socket set. Tight space which made it difficult. The dishwasher works great now!
