Customer Questions and Answers for Impeller Assembly (Wash Pump) by Whirlpool

This impeller assembly replaces a worn or damaged wash-pump impeller to help restore water circulation and spray pressure for better cleaning. Commonly used in compatible Whirlpool wash pumps to address weak wash performance. What it does:

• Spins inside the wash pump to move water through spray arms; damaged fins reduce spray force and cleaning.
• Restores proper flow during wash cycles — symptoms of failure include weak or uneven cleaning.
• Reduces abnormal pump noise and motor strain when the impeller is intact; cracked or missing fins can cause humming or grinding.
• Works with the pump housing and seals to route water; a failed impeller can allow internal leakage or cavitation.

• Always disconnect power (and water, if applicable) before servicing the appliance.
• Inspect pump seals, gaskets, and surrounding components; replace any damaged parts to prevent leaks.
