Possible Causes
Worn upper or lower motor bearings in Whirlaway motor, Misaligned motor shaft, Debris lodged near shaft seal, Overheating damage to bearing surfaces
How to Fix / Troubleshooting
Safety first: Turn OFF power at the breaker. Do not continue to run a disposal that is screeching.
- Step 1 – Check for jams: Ensure there is no foreign object in the grinding chamber causing the noise.
- Step 2 – Listen carefully: Briefly run the unit with water. If the noise is a continuous high-pitched squeal from the motor area, bearings are likely failing.
- Step 3 – Do not lubricate internally: Do not attempt to oil or grease the internal bearings; they are sealed and not accessible.
- Step 4 – Plan replacement: Bearing failure will worsen and can lead to motor seizure or leaks. Schedule replacement of the disposal.
- Step 5 – Remove unit: Disconnect power and plumbing, then install a new Whirlaway disposal per manufacturer instructions.
