Understanding the Causes of Grinder Clogs
Grinder clogs in your Breville Bambino Plus often stem from a few common issues. Coffee oils and residues can accumulate inside the burrs and chute over time, especially if the machine isn’t cleaned regularly. Stale or old coffee grounds tend to stick together and block airflow or movement, leading to a jam. Foreign objects like small stones or broken coffee beans can also cause sudden blockages.
Additionally, using beans with inconsistent grind sizes or attempting to grind large quantities at once can increase the risk of clogs. Recognizing these signs early helps in preventing more severe problems and keeps your espresso tasting perfect.

Signs Your Grinder Is Clogged
- Unusual grinding noises or a sudden silence during operation
- Inconsistent grind size or weak espresso flow
- Machine stops grinding or produces no coffee
- Excessive vibration or resistance when grinding
If you notice any of these signs, it’s time to inspect and clean your grinder to restore optimal performance.
Step-by-Step Guide to Fix a Grinder Clog
- Turn off and unplug the machine: Safety first. Ensure the machine is completely powered down before starting.
- Remove the bean hopper: Carefully lift off the hopper to access the burrs and chute.
- Clear any visible debris: Use a brush or a soft cloth to remove loose coffee grounds around the burrs and chute.
- Disassemble the burr assembly: Consult your Breville Bambino Plus manual for specific instructions on removing the burrs. Usually, you’ll need to unscrew or slide out the burrs carefully.
- Inspect and clean the burrs and chute: Use a small brush or compressed air to dislodge stubborn grounds. Wipe clean with a damp cloth if needed, avoiding water contact with motor parts.
- Reassemble the grinder: Carefully put the burrs and chute back, ensuring all parts are aligned and secured.
- Test the grinder: Plug in the machine, run a small amount of coffee, and observe for smooth operation.
If the clog persists after cleaning, consider replacing worn burrs or consulting a professional technician.
Tips for Preventing Future Clogs
- Use fresh, high-quality beans with consistent grind size.
- Avoid grinding large quantities at once; small batches help prevent buildup.
- Clean the burrs and chute regularly, ideally after every few uses.
- Store beans in an airtight container to prevent moisture and staling.
- Check for foreign objects before grinding beans.
Implementing these habits can significantly reduce the risk of clogs and ensure your espresso machine performs at its best.
Additional Maintenance Tips
Alongside clearing clogs, routine maintenance extends your machine’s lifespan. Use recommended cleaning products like the Breville BEC250 Espresso Machine Cleaning Tablets to remove oils and residues. Regular descaling with appropriate filters, such as Breville Charcoal Filters, can prevent mineral buildup. Always follow manufacturer guidelines for cleaning and maintenance to keep your espresso tasting fresh and your machine working efficiently.
