Whirlpool Recirculation Pump with Sensor (W11542867)

The Whirlpool Recirculation Pump with Sensor circulates water through the dishwasher during the wash cycle. It pulls water from the sump and pushes it to the spray arms to maintain spray pressure and water movement. The sensor monitors water conditions used by the control to adjust the cycle, such as how long to wash and when to drain.

Common failures include a worn motor, a seized impeller, or damage from debris that enters the pump housing. Electrical faults can also occur, such as a failed sensor, a shorted motor winding, or moisture intrusion into the pump’s wiring connection. Over time, heat and vibration can weaken internal components and cause the pump to run intermittently or stop.

These symptoms can help you decide if this part is the source of the problem:

Dishwasher fills and drains but spray arms do not rotate or water does not circulate

Dishes come out with soil left behind because wash pressure is weak

Humming or grinding sounds during the wash portion of the cycle

Wash cycle stops mid-cycle or runs abnormally long due to sensing errors

Intermittent washing where circulation starts and stops during a cycle
