Understanding Common Causes of Grinder Clogs
Grinder clogs in your Breville Bambino Plus often occur due to a buildup of coffee oils, old grounds, or foreign debris. Coffee oils can become sticky over time, especially if you use oily or dark roast beans, causing grounds to stick to the burrs and chute. Additionally, using beans that are too oily or grinding too finely can lead to blockages. External debris like tiny stones or broken coffee beans can also jam the grinder.
Regular maintenance and awareness of your beans’ quality can significantly reduce the risk of clogs. Recognizing early signs of clogging helps prevent damage to the grinder motor and ensures consistent espresso quality.

Step-by-Step Guide to Clearing a Grinder Clog
- Turn Off and Unplug: Always disconnect your machine from power to ensure safety before attempting any maintenance.
- Remove the Bean Hopper: Gently lift the hopper off the grinder. Be careful not to damage the lid or the chute.
- Inspect and Clear Obstructions: Look inside the chute and burr area for any jammed grounds or debris. Use a small brush or a wooden toothpick to carefully dislodge any stuck particles.
- Clean the Burrs: Use a soft brush to clean around the burrs thoroughly. If your model allows, you can remove the burrs for a more detailed cleaning.
- Check the Grind Settings: Ensure the grind size is not set too fine, which can cause clogging. Adjust to a slightly coarser setting if needed.
- Reassemble and Test: Put everything back together, refill the bean hopper, and run a few test grinds to confirm the clog is cleared.
Always consult your Breville Bambino Plus user manual for model-specific instructions, especially when removing burrs or parts.
Maintenance Tips to Prevent Future Clogs
- Regular Cleaning: Use cleaning tablets like the Breville BEC250 or the Replacement Espresso Cleaning Tablet to remove oils and residues periodically.
- Use Fresh Beans: Avoid oily beans or grind just before brewing to minimize oil buildup.
- Avoid Overly Fine Settings: Keep the grind medium or slightly coarser if you experience frequent clogs.
- Check for Foreign Debris: Regularly inspect the chute and burrs for any small stones or foreign objects that might cause jams.
- Proper Storage: Store beans in a cool, dry place to prevent mold or oil rancidity that can contribute to buildup.
Following these habits will help keep your grinder functioning smoothly and extend the lifespan of your machine.
When to Seek Professional Help
If after following these troubleshooting steps your grinder still experiences issues, or if you notice unusual noises, motor overheating, or incomplete grinding, it’s best to contact a professional technician or Breville customer service. Persistent clogs might indicate a deeper mechanical problem or a need for part replacement.
Never attempt to repair or disassemble parts beyond basic cleaning, as this could void your warranty or cause further damage.
