Customer Questions and Answers for Dishwasher Pump And Motor Assembly by Whirlpool

Hello JStross. Remove the bolt securing the wash motor and drip shield in place on the pump assembly. Once the bolt and drip shield are removed, turn the wash motor counter-clockwise until it stops (approximately ¼ turn). Pull the motor straight back from the sump assembly. Some effort may be necessary to dislodge the motor WPW10780877. 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. With the wash motor removed, the separation screen can be removed from the sump base. The thermistor can be removed from the sump by turning it ¼ turn counterclockwise and pulling it out. The thermistor can be removed without removing the sump assembly from the tub. NOTE: Make sure water is completely drained from sump. Access to the thermistor can be gained by removing the access and toe panels while the unit is in its installed position. Hope this helps.
