Jacob R Parker , CO December 18, 2016 Appliance: Whirlpool Undercounter Dishwasher WDT770PAYM0 Whirlpool Dishwasher Wdt770paym0: Diverter motor and grommet leak. How to replace Diverter Motor. Saw leak from diverter motor while machine was running. After removing and reading others same issue, purchased new grommet (accessed from inside machine tub as key cause of leak) and diverter motor (from under machine, had one corroded connection upon inspection so decided to replace since machine was already out). Reassembled, and problem solved. Was not as difficult as I thought, and for less than $100 total cost, was more economical than buying a new dishwasher! Diagram on appliance pros website was perfect. Parts arrived quickly. 2 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 1-2 hours
