Whirlpool Dishwasher Circulation Pump & Motor Assembly W11462455 (Replaces W11048807, CPF25-502)

Is This the Part You Need?

This is the circulation pump and motor assembly — the primary cleaning component in your dishwasher. It pressurizes water and forces it through the spray arms at high velocity to blast food off your dishes. When this pump fails, the dishwasher fills with water normally but produces no spray action. Dishes come out just as dirty as they went in. If your dishwasher fills, drains, but won’t actually wash — this is almost certainly the problem.

Symptoms of a Failed Dishwasher Circulation Pump

• Dishwasher fills with water but makes no sound during the wash cycle (motor dead)
• Loud humming or buzzing without water movement (motor seized or impeller jammed)
• Dishes come out dirty after a full cycle
• Weak or no spray arm pressure
• Water leaking from the bottom of the dishwasher (failed shaft seal)
• Grinding or rattling noises during the wash cycle (damaged impeller or bearings)
• Dishwasher runs through all cycles but dishes remain dirty
• Spray arms not spinning — no water pressure to drive them
• Burning smell from dishwasher bottom (motor burnout)
• Dishwasher trips breaker (motor short circuit)
