Customer Questions and Answers for Drain Pump Motor Assembly (Impeller Included) by Whirlpool

Joe, It's a lot easier if you remove the pump assembly and work on the assembly outside the machine. Here's some help : "Removing the Pump Assembly The entire pump assembly can be removed from inside the dishwasher tub. 1. Remove the access and toe panels from underneath the dishwasher door by removing the two (2) screws securing it to the dishwasher frame. 2. Disconnect the wiring harness connectors (and label them) from the drive motor and pump motor terminals, the soil sensor and the thermistor. 3. Disconnect the drain hose from the drain hose connector on the pump outlet. 4. Remove the pump motor (if you wish).5. Remove the three (3) white, sump tabs that secure the sump assembly to the dishwasher tub. 6. From inside the tub, lift the front of the sump up approximately ½ inch. Push the assembly back and then lift it out. NOTE: When reinstalling the sump assembly, align the locator key with the corresponding slot in the tub opening. Removing the Wash Motor 1. Remove the bolt securing the wash motor and drip shield in place on the pump assembly. 2. Once the bolt and drip shield are removed,turn the wash motor until it stops (approximately ¼ turn).3. Pull the motor straight back from the sump assembly. Some effort may be necessary to dislodge the motor. The volute will remain attached to the motor. NOTE: When reinstalling the wash motor and volute, do not pinch the volute seal between the volute and sump. Use a small amount of rinse aid on the volute seal to help installation." Thanks and Good Luck
