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

Is This the Right Part?

✅ Cross Reference Information

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.
