Step 2: Remove the Bean Hopper and Burrs

  1. Open the bean hopper lid and carefully lift out the hopper.
  2. Use a brush or a soft cloth to remove any loose grounds from the burrs.
  3. Disassemble the grinder to access the burrs, following your user manual’s instructions.

Step 3: Clear and Clean the Grinder

  • Use a small brush or a dedicated cleaning tool to dislodge stuck grounds from the burrs and chute.
  • For stubborn blockages, gently tap or shake the burr assembly to loosen debris.
  • If available, use a cleaning brush or cloth soaked lightly in a mild cleaner; avoid harsh chemicals.

Step 4: Reassemble and Test

Reinstall the burrs and bean hopper securely. Plug in the machine, run a small amount of coffee or a cleaning cycle, and observe if the grinding process is smooth.

Tips and Warnings

  • Regularly clean your grinder to prevent buildup that causes jams.
  • Use the correct grind size recommended for espresso—usually fine but not so fine that it stalls the grinder.
  • Never force parts or use metal tools that could damage the burrs.
  • If issues persist, consult the user manual or contact Breville customer support.
