Is This the Right Part?

✅ Cross Reference Information

Common Symptoms

• Poor or incomplete cleaning because the spray arms are not receiving adequate water flow.
• Little or no audible water movement during the wash portion of a cycle.
• Spray arms do not spin normally.
• Unusual pump-area noise during operation.
• Possible leakage from the motor or pump area.
• Standing water or poor draining may occur when the pump assembly is damaged, although other components can cause the same symptom.

Check Before Replacing

• With the dishwasher empty and operating normally, listen during the wash portion for sustained water-circulation sounds; absence of circulation does not by itself confirm pump failure.
• After disconnecting electrical power, inspect the pump-and-motor wiring connector for looseness, corrosion, or visible damage.
• After disconnecting electrical power and allowing the appliance to cool, inspect the accessible pump area for visible obstruction, damage, or evidence of leakage; do not disassemble the sealed assembly unless the model-specific service documentation permits it.
• Confirm that the dishwasher has filled with water and that the spray arms and filters are not visibly obstructed before attributing poor washing to the circulation assembly.
• Use the appliance's model-specific service diagnostics, if available, to check wash-pump operation; a pump-related symptom can also be caused by the door latch, wiring, control, water supply, filters, or excessive suds.

Pro Tip

Part Details

Key Features

• Genuine Whirlpool OEM dishwasher circulation pump and motor assembly.
• Moves water from the sump area upward through the spray arms.
• Assembly-level replacement for the circulation pump and motor rather than a generic standalone motor.
• Documented for select Whirlpool-family dishwasher applications; model verification remains required.

Installation Notes

• Disconnect electrical power to the dishwasher before accessing or replacing the assembly.
• Follow the installation procedure and parts diagram for the exact dishwasher model; the supplier listing does not provide universal installation instructions for W11178672.
• Inspect and reconnect the wiring and water connections carefully, and check the pump area for leaks after installation before returning the dishwasher to normal use.
• Do not substitute a drain pump or another visually similar pump assembly; verify the appliance model and exact part number first.
