Midea Pump or Motor Bearing Wear

Dishwasher makes a high-pitched squealing or whining noise during operation.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Worn bearings in Midea circulation pump, Worn bearings in drain pump, Cavitation due to low water level, Debris partially contacting impeller

Safety first: Disconnect power before accessing the base.

Verify water level: Ensure the dishwasher is filling to the correct level; low water can cause pump cavitation noise.
Inspect pumps: Access the base and run a brief test (with caution) to identify which pump is noisy.
Remove debris: Remove the noisy pump and check for debris rubbing the impeller.
Replace pump: If the noise is due to worn bearings, replace the affected Midea pump assembly.
