Christopher D Endwell , NY April 21, 2020 Appliance: Whirlpool Dishwasher WDF760SADB2 Whirlpool Dishwasher Wdf760sadb2: Circulation pump would only work intermittently; no error codes. How to replace Drain Pump. Bought a new sump/motor assembly to make it an easy swap out instead of buying just the motor. Assembly also came with a new diverter motor so I won't have to worry about having to go back in there if that failed. I also purchased new turbidity sensor and drain pump (which I found out had a small leak in addition to starting to fail) since I was already in there. The machine works like it's brand new now. 5 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 1-2 hours
