Waste Maid Worn Bearings / Hardened Mounts / Thin Sink

Garbage disposal is unusually loud compared to previous operation (without obvious grinding of foreign objects)

Possible Causes

Worn motor bearings, Hardened or missing rubber mounting gasket, Loose sink flange transmitting vibration, Thin stainless sink amplifying noise

How to Fix / Troubleshooting

Safety First: Turn OFF the disposal before inspecting mounts.

  • Check for foreign objects: First confirm there are no utensils or debris causing noise by inspecting the chamber with a flashlight.
  • Inspect mounting gasket: Under the sink, verify the rubber mounting gasket is intact and not compressed to the point of metal-to-metal contact.
  • Tighten sink flange: Ensure the mounting ring and sink flange are snug and evenly tightened.
  • Noise pads: For very thin sinks, consider adding sound-dampening pads or a support bracket to reduce resonance.
  • Replace if bearings are noisy: A growling or roaring sound from the motor area indicates bearing wear; replace the disposal.
