Disassemble the Grinder Area
- Turn off and unplug the espresso machine.
- Remove the bean hopper, following your model’s instructions, to access the burrs.
- Carefully detach the burrs using a small wrench or by hand, depending on your model.
- Inspect for any coffee grounds, oil buildup, or debris blocking the grinder pathway.
Be gentle during this process to avoid damaging the burrs or internal components. If your grinder has a removable tray or chute, clean it thoroughly.
Clean the Grinder Components
Use a soft brush or a cloth to remove coffee residue from the burrs and internal pathways. For stubborn buildup, soak the parts in warm water with a small amount of Breville cleaning tablets or use a dedicated espresso machine cleaning solution. Avoid using harsh chemicals that could damage the machine.
If the burrs are worn or damaged, consider replacing them with compatible parts to restore grinding efficiency.
Reassemble and Test the Machine
- Reattach the burrs securely and replace the bean hopper.
- Refill the hopper with fresh, dry coffee beans—preferably medium grind to avoid oily beans that cause clogging.
- Plug in the machine and run a test grind cycle without coffee to clear any residual debris.
- Observe if the grinder operates smoothly and without blockage.
If issues persist, repeat the cleaning process or consider replacing worn parts. Regular maintenance can prevent future clogging.
Prevent Future Clogging
To minimize clogging, use high-quality, dry coffee beans and grind only the amount needed for each shot. Schedule regular cleaning with espresso machine-specific tablets or cleaning cycles recommended by Breville. Avoid storing coffee beans in humid environments, as moisture can cause beans to become oily and clog the grinder.
Additionally, avoid overfilling the bean hopper and ensure the grind size is appropriate; too fine a grind can increase the risk of clogging.
