Understanding the Causes of Grinder Clogs
Grinder clogs in your Breville Bambino Plus typically result from a few common issues. The most frequent cause is grinding beans too finely or using beans that are old and stale, which can lead to buildup and blockage. Additionally, using too much coffee at once can overload the grinder, causing residual coffee grounds to jam the mechanism.
Other factors include infrequent cleaning, which allows coffee oils and residues to accumulate and harden, impeding the grinding process. Over time, these residues can cause a significant clog, reducing grind consistency and machine performance.
Understanding these causes helps you prevent future clogs and maintain optimal espresso quality. Regular maintenance and proper bean selection are key to avoiding these issues.

Step-by-Step Fix for Grinder Clogs
- Turn off and unplug the machine. Always disconnect your Breville Bambino Plus before performing maintenance.
- Remove the bean hopper and grind chute. Carefully detach these parts following your user manual to access the grinder.
- Clear out residual coffee grounds. Use a small brush or a soft cloth to sweep away any loose grounds or blockages in the grinder chamber.
- Perform a cleaning cycle with tablets. Use official Breville cleaning tablets (e.g., BEC250) or a safe descaling product. Follow the instructions for dissolution and run the cleaning cycle as directed.
- Inspect and clear the burrs. Check the burrs for any stuck grounds or debris. Gently remove any obstructions using a brush or soft tool.
- Reassemble the grinder parts. Ensure everything is dry and correctly fitted, then reassemble the chute and hopper.
- Test the grinder. Run a small amount of coffee to verify that the grind is now smooth and the machine functions properly.
Preventative Tips for Ongoing Maintenance
- Use the right grind setting. Avoid overly fine settings that can cause jams, especially with less oily beans.
- Grind in smaller batches. Do not overload the grinder; small, consistent doses help prevent blockages.
- Clean regularly. Use cleaning tablets monthly and wipe down the burrs and chute weekly.
- Choose fresh beans. Stale beans tend to produce more residue, increasing clog risk.
- Replace water filters periodically. Proper water quality reduces mineral buildup that can compound clogging issues.
