Customer Questions and Answers for Circulation Pump And Motor (Dishwasher) by Whirlpool

This dishwasher circulation pump and motor drives wash water through the spray arms for effective cleaning. Replacing a failed wash motor restores strong spray pressure and consistent cleaning performance throughout the cycle.

• Circulates water through the spray arms to wash and rinse dishes
• Maintains proper flow and pressure from the sump to all spray arms
• Direct replacement for a seized, noisy, or non-running wash motor
• Common symptoms: poor cleaning, no spray action, or humming/buzzing during wash

• Disconnect power at the breaker and shut off water supply before servicing.
• Access is from the bottom/front; many models require removing the toe panel and/or sliding the dishwasher out.
• Connect the wiring, seat the pump seal fully in the sump, and lock the assembly in place per your model's procedure.
• After reassembly, run a brief fill-and-wash to check for leaks and proper spray action.
