Possible Causes

Worn circulation pump bearings, Worn drain pump bearings, Cavitation due to low water level, Spray arm bushings worn

How to Fix / Troubleshooting

Safety First: Disconnect power before working under the unit.

  • 1. Verify water level: Ensure the dishwasher is filling properly; low water can cause pump cavitation noise.
  • 2. Localize the noise: Listen carefully to determine if the sound occurs during wash (circulation pump) or drain (drain pump).
  • 3. Inspect pumps: Access the pumps from below. Spin the impellers by hand; roughness or play indicates worn bearings.
  • 4. Replace noisy pump: Install a new Frigidaire circulation or drain pump as appropriate.

Ignoring bearing noise can lead to sudden pump failure and leaks.
