Whirlpool Dishwasher Pump Diverter Motor W10843811, Replaces W10380170, W10849447

Is This the Right Part?

✅ Cross Reference Information

Common Symptoms

• Uneven spray-arm operation or inconsistent water distribution
• Poor cleaning in one or more spray-arm zones
• Clicking, grinding, humming, or abnormal diverter-motor noise
• Diverter-related diagnostic errors or failure to find the diverter position
• Leakage near the diverter-motor shaft or seal area

Check Before Replacing

• Disconnect electrical power before inspecting the diverter-motor circuit, wiring, or connectors.
• Run the dishwasher’s manufacturer diagnostic cycle only as specified for the appliance model; listen for the diverter operating and observe shaft movement indirectly where access permits.
• Inspect the diverter-motor harness and connectors for loose connections, corrosion, overheating, or visible damage.
• With power disconnected and using the applicable service documentation, check diverter-motor resistance; one Whirlpool service manual specifies approximately 600–1800 ohms for the diverter-motor circuit.
• If the motor hums or vibrates but rotation is limited, inspect for mechanical binding of the diverter shaft or disk and inspect the associated seal; these checks do not by themselves confirm motor failure.

Installation Notes

• Disconnect electrical power before servicing.
• Access is from the underside of the dishwasher; remove only the panels and components required by the appliance-specific service instructions.
• Inspect the diverter shaft, disk, and seal during replacement because mechanical binding or seal damage can affect the new motor.
• Reconnect the motor harness securely and perform the appliance diagnostic or verification cycle specified for the model before returning the dishwasher to service.
• Do not apply grease to the diverter motor or diverter-motor seal unless the model-specific service documentation explicitly calls for it.
