Bauknecht Worn Circulation Pump Bearings

Dishwasher makes a high-pitched whining or squealing noise 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

Aged circulation pump, Water ingress into pump motor, Misaligned pump mounting, Cavitation due to low water level

Safety first: Unplug the dishwasher.

Check water level: Ensure the dishwasher fills to the correct level; low water can cause cavitation noise.
Listen to pump: Identify the noise source; if it clearly comes from the circulation pump, bearings are likely worn.
Replace pump: Access and replace the circulation pump assembly with a compatible Bauknecht part.
