Danby Worn Circulation Pump Bearings / Motor Noise

Dishwasher emits a high-pitched squeal or whine during wash.

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

Aging circulation pump, Dry or worn motor bearings, Cavitation due to low water level, Obstructed pump inlet

Safety first: Turn off power before accessing the base.

Verify water level: After filling, open the door and check that water covers the filter area adequately. If low, investigate inlet issues.
Clean filters and sump: Ensure no obstructions are restricting water flow to the pump.
Listen closely: If the noise clearly comes from the pump area and persists, the circulation pump is likely worn and should be replaced.
