Tweeny Dull Grinding Components / Reduced Grinding Efficiency

Garbage disposal runs but does not grind food effectively; food remains unprocessed

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

Worn grinding plate, Smoothed grind ring teeth, Stuck impeller lugs, Low motor torque due to aging

Safety First: Turn OFF and disconnect power before inspecting.

Step 1 – Inspect grinding surfaces: With a flashlight, look for smooth, worn grind ring teeth or heavily rounded lugs.
Step 2 – Free stuck lugs: Use a wooden tool to pivot each lug. Free any that are stuck with penetrating oil applied sparingly (avoid overspray).
Step 3 – Test with small load: Restore power, run water, and test with small soft food scraps.

If grinding remains poor, the internal components are worn. Replace the Tweeny disposal for proper performance.
