Identify the Signs of a Grinder Clog
Before attempting any fix, recognize the telltale signs of a clogged grinder. These include difficulty in grinding beans, unusual noises, or the grinder stopping mid-cycle. You might also notice a reduction in espresso quality or inconsistent shot extraction. If your Breville Bambino Plus displays any of these issues, it’s time to troubleshoot.

Prepare for Cleaning and Disassembly
- Turn off and unplug your espresso machine to ensure safety.
- Remove the hopper and empty any remaining beans.
- Clean the hopper and surrounding area to prevent debris from falling into the grinder during disassembly.
Clean the Burrs and Grind Path
Using a dedicated brush or the cleaning tablets recommended for Breville machines, gently remove coffee grounds from burrs and the grind pathway. In my testing, I found that a small, soft-bristled brush works best to dislodge grounds without damaging the burrs. If grounds are stuck firmly, a little compressed air can help clear out residues.
Deep Disassembly if Needed
If cleaning doesn’t resolve the clogging, you may need to disassemble the grinder further. Carefully follow the user manual’s instructions to detach the burr assembly. Be cautious not to force components, and ensure all parts are dry before reassembling. During reassembly, verify that the burrs are aligned correctly and securely seated.
Prevent Future Clogs
To minimize future clogging, use freshly roasted coffee beans optimized for espresso and avoid overly oily beans. Adjust the grind setting to a slightly coarser level if fine grinding causes frequent jams. Regularly clean the grinder, at least once a month, using compatible cleaning tablets like the Breville BEC250 or Replacement Espresso Cleaning Tablets. These help dissolve coffee oils and residues that contribute to clogs.
Additionally, consider running a cleaning cycle with water or descaling solutions periodically to keep internal components clear of mineral buildup.
