How to Fix / Troubleshooting

Safety: Unplug the machine before accessing the grinder.

  • Empty hopper: Remove all beans and vacuum out loose fragments.
  • Check for foreign objects: Inspect the grinder inlet for stones or hard debris and remove carefully.
  • Adjust grind: Move the grind setting slightly coarser to reduce load on the grinder.
  • Run without beans: Briefly run the grinder empty (if your model allows) to see if the noise persists. If it does, internal parts may be worn.

Persistent abnormal noise usually means the grinder assembly needs to be disassembled, cleaned, or replaced. This is best done by a technician.
