Possible Causes
Metal utensil or screw inside chamber, Broken impeller lug, Loose screw from Franke grind ring, Warped grinding plate
How to Fix / Troubleshooting
Safety first: Turn OFF power at the switch and breaker before inspecting.
- Inspect chamber: Shine a flashlight into the sink opening and use tongs to remove any foreign objects (spoons, bottle caps, screws).
- Check impeller lugs: Gently move the turntable with a wooden stick to inspect the impeller lugs. If one is broken or loose, the grinding assembly is damaged.
- Test noise: Restore power, run water, and briefly test. If loud screeching persists with no foreign objects, internal components are likely bent or worn.
- Replace grinding assembly: Replace the Franke grinding plate and impeller assembly or the entire disposer if parts are not separately available.
