Use only with power disconnected and connectors dry before restart.
The Whirlpool dishwasher circulation pump, also called the wash pump motor, moves water through the spray arms. If the dishwasher fills and drains but dishes stay dirty, the wash pump is one of the first parts to test.
Do not order a pump until you know the dishwasher is filling to the right level and the spray arms are not blocked.
| Symptom | Likely cause |
|---|---|
| Fills but no spray sound | Failed circulation motor or no power |
| Loud hum during wash | Jammed or failing pump motor |
| Weak spray from arms | Clogged filter, pump wear, low water |
| Leaks under center of tub | Sump seal or pump housing issue |
| Wash motor runs intermittently | Harness, control, or motor thermal fault |
Call service if the pump wiring is burned, the dishwasher leaks after reassembly, or live-voltage testing is needed. Always shut off power and water before pump access.
A bad circulation pump may hum without spraying, spray weakly, stop mid-wash, or leave dishes dirty while the dishwasher still fills and drains normally.
That depends on the model and leak condition. Replace only the motor if the sump is sound and serviceable. Use the full pump and sump assembly if seals, housing, or chopper area are damaged.
Check the filter, spray arms, float, wiring connector, and voltage to the motor. A blocked filter or dead control output can mimic a failed circulation pump.
