Garbage disposal emits a metallic ringing or bell-like sound during operation.

Safety first: Turn off power before inspecting.

• Step 1 – Inspect for foreign objects: Remove any visible debris from the chamber using tongs.
• Step 2 – Rotate impeller: Manually rotate the impeller plate with a wooden tool and listen/feel for scraping or contact points.
• Step 3 – Brief test: Restore power and run the unit with water. If the ringing persists and no debris is present, the impeller or bearings may be worn.
• Step 4 – Replace disposal: Internal alignment issues are not user-serviceable; replace the unit if the sound is persistent and bothersome.
