Whirlpool Corporation Washer drain pump (water pump) WPW10515399, Replaces W10422971, W10515399

Genuine OEM washer drain pump that removes water during the drain portion of the wash cycle.

Is This the Right Part?

Common Symptoms

• Standing water remains in the washer after drain or spin.
• Drain cycle times out or produces a drain-related error.
• The washer makes unusual humming, grinding, or rattling noises during draining.
• Water flow from the drain hose is weak despite an unobstructed hose and filter.

Check Before Replacing

• Disconnect power before servicing and check the drain hose, pump filter, pump inlet, and connected hoses for visible obstructions.
• Run the washer’s model-specific diagnostic or drain test and observe whether the pump operates and water exits the drain hose.
• With power disconnected, inspect the pump wiring and connectors for loose, damaged, or corroded connections.
• If the applicable service documentation specifies a pump resistance test, compare the measured resistance with that model’s specification; an open circuit can indicate a failed pump, but a normal reading does not by itself prove the pump is good.
• If the pump and hoses appear clear, verify harness continuity and control output according to the washer’s model-specific service documentation before replacing the pump.
