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.

Possible Causes

Worn circulation pump bearings, failing drain pump, misaligned pump housing

Safety first: Disconnect power.

Isolate noise: Listen carefully to determine if the noise occurs during wash (circulation pump) or drain (drain pump).
Inspect pumps: Access the pumps from underneath and check for signs of leakage or rust around the motor shafts, which indicate bearing failure.
Check mounting: Ensure pumps are securely mounted and not vibrating against the frame.

Repair action: Replace the noisy pump (circulation or drain) as bearings are not serviceable. Verify quiet operation after replacement.
