Tweeny Worn Bearings / Internal Mechanical Wear

Garbage disposal is very loud compared to when it was new, with a harsh grinding sound

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Aged motor bearings, Corroded grinding components, Long-term operation with imbalance, Water intrusion into motor

Safety First: Turn OFF and disconnect power before inspection.

Step 1 – Rule out foreign objects: Clear any debris from the chamber as described in noise troubleshooting.
Step 2 – Listen to motor alone: Briefly run the unit empty with water. A continuous growl or whine indicates bearing wear.
Step 3 – Check for wobble: Observe the unit while running; excessive movement suggests internal wear.

Worn bearings are not serviceable on most Tweeny models. Replacement of the disposal is recommended.
