Whirlpool Washer Pump (W11458345)

The Whirlpool Washer Pump moves water out of the washer tub and through the drain hose during drain and spin cycles. It helps the control complete cycle steps by clearing water at the right time. If the pump cannot move water as designed, the washer may stop mid-cycle or leave water in the tub.

Common causes of failure include coins, lint, or small items lodged in the pump or inlet, which can jam the impeller. The pump can also wear over time, leading to weak flow, louder operation, or leaks at the pump housing or seals. Electrical issues in the pump motor can prevent it from starting or can cause it to run intermittently.

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

Washer will not drain, or drains slowly

Water left in the tub at the end of the cycle

Humming or grinding sound during drain, with little or no water movement

Cycle stops, pauses, or will not advance when it should drain

Water leaking from the pump area during or after draining

Error codes related to draining or long drain times, depending on model
