Identify the Cause of the Grinder Clog
Before attempting to fix the clog, observe when the issue occurs. Common signs include the grinder stopping mid-cycle, unusual noises, or a persistent blockage with no grounds being dispensed. Check if the grind setting is too fine, which can cause grounds to stick or jam.
Additionally, accumulated coffee grounds or oil residues can clog the burrs or chute, leading to frequent jams. Recognizing whether the problem is due to grind size, coffee type, or buildup will help determine the right troubleshooting steps.

Step-by-Step Cleaning Procedure
- Turn off and unplug your Breville Bambino Plus to ensure safety.
- Remove the bean hopper and empty any remaining beans. Clean the hopper with a damp cloth and dry thoroughly.
- Access the burr grinder area by removing the top or side panel, following the user manual instructions.
- Use a soft brush or a dedicated cleaning tool to gently clear any coffee grounds or debris from the burrs and chute.
- For a deeper clean, run a cleaning cycle using Breville-approved cleaning tablets, such as the Breville BEC250, dissolved in the water reservoir.
- Reassemble the grinder parts carefully, ensuring all components are securely fitted.
- Run a few test grinds with plain coffee to verify if the clog is resolved.
Prevent Future Clogs
To keep your grinder running smoothly, use the correct grind size for espresso—usually a fine but not powdery consistency. Avoid overfilling the bean hopper; a full hopper can cause uneven grinding and jams.
Regularly clean the burrs and chute, ideally once a month, and use Breville cleaning tablets periodically to remove oil build-up. Also, switch to high-quality, fresh coffee beans to minimize oil and residue that contribute to clogging.
Tips and Warnings
- Tip: Always follow the manufacturer’s instructions when disassembling or cleaning your espresso machine.
- Warning: Do not use harsh chemicals or abrasive tools that could damage the burrs or internal components.
- Ensure the machine is unplugged during cleaning to prevent electrical hazards.
- Avoid grinding very oily beans frequently, as they can contribute to buildup and jams.
- Check for worn or damaged burrs, which may need replacing if clogging persists after cleaning.
When to Seek Professional Help
If cleaning and maintenance do not resolve the clog, or if you notice persistent grinding issues, it may be time to contact a certified repair technician. Internal component damage or worn burrs may require expert diagnosis and replacement.
Always use genuine replacement parts and accessories to ensure compatibility and safety.
