Possible Causes
Aging motor bearings, Corrosion inside motor housing, Long-term imbalance from grinding hard objects, Water intrusion into motor
How to Fix / Troubleshooting
Safety first: Turn off power before inspecting. Do not disassemble the sealed motor housing.
- Rule out loose mount: Confirm the Quick Lock® mount and discharge piping are tight and not rattling.
- Check for foreign objects: Inspect the grind chamber and remove any debris that could cause noise.
- Listen to motor: If the loud roaring or growling persists with an empty chamber and secure mount, the motor bearings are likely worn.
- Plan replacement: InSinkErator motors are not field-serviceable. Replace the disposal with a new unit of similar or upgraded model.
