The Dishwasher Circulation Motor is an OEM part for LG dishwashers. It plays a crucial role in the dishwasher's operation by pumping water through the spray arms during the wash cycle, ensuring that dishes are thoroughly cleaned. Over time, the circulation motor can fail due to normal wear and tear, electrical issues, or blockages caused by debris. A malfunctioning motor can lead to inefficient cleaning and increased noise levels. Regular maintenance and avoiding overloading the dishwasher can help extend the motor's lifespan. Symptoms of a bad circulation motor include: Dishes not being cleaned properly Unusual noises during the wash cycle The dishwasher not completing cycles Water not circulating within the dishwasher This OEM LG part is also compatible with Sears/Kenmore.Part Number 4681ED1004B (AP5325099) replaces 4681ED1004D, 2024578, 4681ED1004A, AH3579321, EA3579321, PS3579321.
