John S St Louis , MO November 07, 2014 Appliance: Whirlpool Undercounter Dishwasher WDF780SLYB0 Whirlpool Dishwasher Wdf780slyb0: Dishwasher was silently leaking from motor. How to replace Diverter Motor. Looked up schematics on several sites, viewed YouTube video on similar situation.. ordered more parts than needed, as I hadn't inspected the problem completely due to its "hidden" location under the tub. However, after studying the schematics, swapping out the part was only slightly difficult.. had to lift the power scrub nozzle out of its inlet and then twist the water inlet tubes counter-clockwise to expose the plastic disc that came with the motor. Two (2) Torx screws released the motor from the bottom of the dishwasher, and the electrical connection was easily made with the snap in fittings. I was able to return the part I didn't use. Pleased that we dodged a service call or two. 37 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 1-2 hours
