The Circulation Motor is an OEM part for Whirlpool dishwashers. It is responsible for pumping water through the spray arms to ensure thorough cleaning of dishes during the wash cycle. This motor helps maintain consistent water pressure and flow, crucial for effective dishwashing performance.

Over time, the circulation motor can fail due to factors such as motor wear, electrical issues, or blockages that cause the motor to overheat or become damaged. Regular use and the buildup of debris or hard water deposits can also contribute to motor failure.

Symptoms of a bad circulation motor include:

• Poor cleaning results
• Unusual noises during the wash cycle
• Water not circulating properly
• Dishwasher not completing cycles

This OEM part is also compatible with Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper, and Kenmore models.

This run capacitor helps start and keep the motor running smoothly by providing the necessary phase shift and torque boost. A weak capacitor can cause hard starting, humming, or intermittent motor operation.

• Supplies continuous phase shift to maintain motor rotation
• Helps the motor start reliably under load
• Symptoms can include humming, slow or no start, or overheating shutdown
• Restores normal operation when the original capacitor has weakened

• Disconnect power before servicing; discharge the old capacitor safely
• Note wire locations and transfer leads to the new capacitor one-by-one
• Mount securely in the original bracket or location to prevent vibration
• If the motor still won't start, further diagnosis of the motor or start device may be required
