Understanding the Causes of Grinder Clogs
Grinder clogs in your Breville Bambino Plus or similar models often happen due to several factors. The most common cause is setting the grind too fine, which results in coffee grounds that are difficult to pass through the burrs. Oily or stale beans can also increase the likelihood of clogging because they produce sticky residues that build up in the grinder.
Additionally, insufficient cleaning can lead to the accumulation of coffee oils and residual grounds, further impeding grinding performance. Using beans that are not suitable for espresso or grinding in large quantities without cleaning can exacerbate these issues.
Understanding these root causes is essential for troubleshooting and preventing future clogs effectively.

Step-by-Step: How to Fix a Grinder Clog in Your Breville
- Turn off and unplug your machine. Safety first—never attempt to service your espresso machine while plugged in.
- Remove the bean hopper. Carefully lift the hopper out of the grinder, following your model’s instructions.
- Clear any visible blockages. Use a brush or a soft wooden pick to gently dislodge stuck grounds in the burrs or chute. Do not use metal tools that could damage the grinder.
- Clean the burrs and chute. Wipe with a dry cloth or use a dedicated grinder brush to remove residual grounds and oils.
- Run a cleaning cycle or grind without beans. Use a cleaning tablet (such as the Breville BEC250 or a compatible cleaning tablet) or grind some dry rice to absorb oils and clear the pathway.
- Reassemble and test. Replace the hopper, plug in the machine, and run a test grind to ensure smooth operation.
Preventing Future Grinder Clogs
- Use fresh, dry beans. Oily or stale beans are more likely to cause buildup and clogs.
- Adjust your grind setting. Avoid overly fine settings that strain the grinder and cause jams.
- Clean regularly. Use a dedicated brush or cleaning tablets every few weeks to remove oils and residues.
- Don’t grind large quantities at once. Break up your beans into smaller doses to prevent overload.
- Check for bean quality and moisture. Beans with high moisture content can cause more sticky residues.
Tips and Warnings for Safe Maintenance
Always ensure your espresso machine is unplugged before performing any cleaning or maintenance. Use only recommended cleaning products, such as Breville-approved tablets or safe methods like dry rice or grinder brushes. Avoid sharp tools or metal objects that could damage the burrs or chute.
If you are unsure about disassembling your grinder, consult the user manual or contact Breville customer support for guidance. Regular maintenance not only prevents clogs but also prolongs the life of your espresso machine and ensures consistently great coffee.
