Identify the Cause of the Clog
Before attempting repairs, determine whether the clog is due to residual coffee oils, grounds buildup, or a mechanical jam. Common signs include difficulty grinding, unusual noises, or the grinder stopping mid-operation. Check for visible blockages or coffee grounds lodged in the burrs or chute. If the grinder stalls or produces inconsistent grounds, it’s likely a clog issue.
Understanding the root cause helps you choose the appropriate cleaning or repair method, ensuring a safe and effective fix.

Unplug and Disassemble the Grinder
- Ensure the machine is turned off and unplugged to prevent electrical hazards.
- Remove the bean hopper carefully, following your Breville Bambino Plus manual instructions.
- Open the grinder compartment by removing the top cover or burr assembly, depending on your model.
- Inspect the burrs, chute, and surrounding areas for coffee grounds or oil residue.
Use a soft brush or a cleaning cloth to clear loose grounds. Avoid using water directly on the grinder parts, as moisture can cause damage.
Clean the Grinder Thoroughly
- Use a dedicated espresso machine cleaning tablet, such as the Breville BEC250, to dissolve coffee oils and residues. Follow the instructions for dissolution time and application.
- For mechanical cleaning, gently brush the burrs, chute, and surrounding components to remove stubborn grounds.
- Use a dry cloth or compressed air to remove loose debris and ensure no blockages remain.
Regular cleaning with suitable tablets helps prevent oils from becoming sticky, which can cause clogs over time.
Check and Adjust the Grind Size
If your grind is too fine, it can increase the likelihood of clogging. Adjust the grind setting to a slightly coarser level according to your machine’s manual. Test by grinding a small amount of beans and observe if the flow improves.
Remember, the ideal grind should allow grounds to flow freely without excessive resistance. Proper grind size reduces strain on the grinder and minimizes clogs.
Reassemble and Test the Machine
- Reassemble the burrs, chute, and bean hopper securely.
- Plug in your machine and run a short grind cycle without beans to clear out any residual debris.
- Insert fresh beans and run a test shot. Check for smooth grinding and consistent ground flow.
If the clog persists, repeat the cleaning process or consider replacing worn burrs or seals as recommended by your machine’s manual.
Prevent Future Clogs with Routine Maintenance
To keep your Breville Bambino Plus running smoothly, establish a regular cleaning schedule using approved cleaning tablets like the Breville BEC250 or the Replacement Espresso Cleaning Tablet. Clean the grinder and burrs every few weeks, especially if you notice changes in grind consistency or noise.
Additionally, use fresh, dry coffee beans and avoid overfilling the hopper. Proper grind size and routine descaling help prevent oil and grounds buildup that cause clogging.
