Possible Causes

Worn circulation pump bearings, Debris in pump, Cavitation from low water level, Failing drain pump

Safety: Disconnect power before accessing pumps.

Verify water level: Ensure the dishwasher is filling properly; low water can cause pump cavitation and noise.
Isolate the source: Listen to determine if the noise occurs during wash (circulation pump) or drain (drain pump).
Inspect pump for debris: Remove and inspect the noisy pump for obstructions.
Replace noisy pump: If bearings are worn or the motor squeals even when clean, replace the affected pump assembly.
