Whirlpool Dishwasher Pump (W11087376)

The Whirlpool Dishwasher Pump moves water through the dishwasher during wash and rinse cycles. It sends water to the spray arms and helps maintain water circulation so detergent can dissolve and soil can rinse away. A working pump supports steady water flow and consistent cleaning performance.

Pump problems often start from wear on the motor and bearings, damage to the impeller, or debris getting past the filter area. Hard water buildup can add drag to moving parts. Leaks can also develop if the pump housing or seals degrade over time, or if the unit has been run with blocked circulation.

Common signs that point to a pump issue include:

• Dishes come out dirty or detergent remains in the dispenser because water is not circulating well
• Weak or uneven spray from the spray arms, or spray arms that do not turn
• Unusual grinding, humming, or rattling sounds during the wash portion of the cycle
• Cycle stalls or ends with poor washing results even though the unit fills with water
• Water leaks from the pump area underneath the dishwasher
• Intermittent washing performance that changes from cycle to cycle
