Wesley T Rexford , NY February 20, 2019 Appliance: Whirlpool Undercounter Dishwasher WDT790SAYB2 Whirlpool Dishwasher Wdt790sayb2 / : Leaking through the diverter. How to replace Diverter Motor. Replaced the diverter and sump. Be careful of the clamps for the sump drain hose. Ours was one used and I needed to purchase new clamps as well after replacing the sump. Actually, right now, they are help on by cable ties until my new clamps come in. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
