Whirlpool Worn Pump Bearings or Motor

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 circulation pump bearings, Failing drain pump, Cavitation due to low water level

Safety First: Turn off power before accessing pumps.

Verify water level: Ensure the dishwasher is filling to the proper level; low water can cause pump cavitation and noise.
Isolate noise source: Listen during wash vs. drain to determine if the circulation or drain pump is noisy.
Inspect pumps: Access the noisy pump from below. If the impeller is intact but the motor is loud or rough, replace the pump assembly.
