Leaking water at motor Trevor B. • Columbus, OH • June 01, 2014 Appliance: Whirlpool Undercounter Dishwasher WDT790SAYM0 My Repair & Advice Changed sump to replace diverter motor washer. Appliance parts pros made finding the repair part I needed very simple and easy. I ordered the part I needed on Tuesday and had it in my hands on Wednesday and that was with the cheapest shipping! I hope I dont need to come back to this website soon, but when another appliance breaks it will be my first stop! Was this review helpful to you?
