How to Fix / Troubleshooting

Safety first: Unplug before accessing grinder internals.

Cleaning:

  • Clean the grinder and chute thoroughly with a brush and vacuum.
  • Ensure no grounds are caked around the burrs or chute.

Adjustments:

  • Verify the strength setting and ensure it changes the grind duration (listen for longer or shorter grinder run).
  • Store beans in a dry, cool place to avoid clumping.

If burrs are dull or chipped, replace the burr set to restore consistent grinding.
