Common Causes of Grinder Clogs in Breville Bambino Plus
Grinder clogs in your Breville Bambino Plus can occur due to several reasons. The most common cause is buildup of coffee oils and residue from frequent use, which can harden and block the burrs or chute. Moisture from stale or improperly stored beans can also cause the coffee grounds to clump together, leading to jams. Additionally, using beans that are too oily or grinding excessively fine can put extra strain on the grinder, increasing the likelihood of clogging.
Other contributing factors include poor maintenance routines, such as neglecting to clean the burrs and chute, and infrequent descaling, which can lead to mineral deposits interfering with the grinding process. Identifying these causes helps target the specific issue and avoid future clogs.

Step-by-Step: How to Unclog Your Breville Bambino Plus Grinder
- Turn off and unplug the machine. Safety first—ensure the grinder is completely powered down before starting any cleaning or maintenance.
- Remove the bean hopper. Carefully lift out the hopper and empty any remaining beans. Check for bean fragments or stuck grounds.
- Inspect the burrs and chute. Look for any hardened coffee residues or blockages. Use a soft brush or a dedicated grinder cleaning brush to gently remove debris.
- Use cleaning tablets if needed. For stubborn buildup, dissolve a Breville BEC250 cleaning tablet in warm water and run it through the grinder as if grinding beans. This helps dissolve oils and residues.
- Perform a thorough cleaning. Wipe down all accessible parts with a dry cloth. Avoid using water directly on the motor or electrical components.
- Reassemble the grinder and test. Reinstall the hopper, add fresh beans, and run a test grind. Adjust grind settings if necessary.
If clogging persists, repeat the cleaning process or consider replacing worn burrs.
Tips for Preventing Future Clogs
- Use high-quality, dry beans. Store beans in a cool, dry place to prevent moisture absorption.
- Adjust grind size appropriately. Avoid grinding too fine, which can increase strain on the grinder and cause blockages.
- Clean regularly. Schedule monthly cleanings to remove oil buildup and coffee residue.
- Use cleaning tablets periodically. Incorporate a cleaning routine with tablets like Breville BEC250 to maintain optimal performance.
- Inspect and replace burrs as needed. Worn burrs can cause inconsistent grinding and increase clog risk.
Safety Warnings and Best Practices
Always unplug your Breville Bambino Plus before performing any cleaning or maintenance. Use only recommended cleaning products and tools to avoid damage. Be cautious with sharp burrs—handle them carefully to prevent injury. Do not immerse electrical components in water or use harsh chemicals that could corrode parts.
