Possible Causes
Worn grinder motor bearings, Loose grinder mounting screws, Foreign object in grinder, Stripped plastic gears (if gear-reduced)
How to Fix / Troubleshooting
Safety first: Unplug the unit before inspection.
Steps to try:
- Check for foreign objects: Remove beans and inspect the grinder chamber for stones or metal pieces.
- Tighten mounts: Access the grinder assembly and tighten any loose mounting screws or brackets.
- Listen test: With the unit reassembled, run a short grind cycle and listen. Grinding noise only during operation is normal; loud screeching or grinding when idle indicates a mechanical fault.
If noise persists and is accompanied by vibration or burning smell, the grinder motor or gears may need replacement.
