Identify the Cause of the Clog
Before attempting repairs, determine why your grinder is clogging. Common causes include using overly fine grind settings, stale beans, or accumulated oils and coffee residues inside the grinder mechanism. Check for visible blockages or jams by gently removing the bean hopper and inspecting the burrs and chute. If the grinder stalls or produces inconsistent grounds, these signs indicate a clog that needs cleaning or adjustment.

Turn Off and Unplug Your Machine
Safety first: always turn off and unplug your Breville Bambino Plus before conducting any maintenance. This prevents electrical hazards and ensures the grinder motor isn’t active during cleaning. Wait a few minutes after unplugging to allow internal components to cool down if recently used.
Remove and Clean the Grinder Components
- Remove the bean hopper by gently lifting it off. Empty any remaining beans.
- Use a soft brush or a vacuum cleaner with a narrow nozzle to remove loose coffee grounds and dust from the burrs and chute.
- Use a dedicated cleaning brush to dislodge stuck particles around the burrs.
- If your model allows, remove the burrs for a more thorough cleaning. Wash the burrs with warm water and dry completely before reassembling.
- For stubborn residues, consider using a coffee grinder cleaning tablet designed for espresso machines (see recommended products below).
Adjust the Grind Setting and Reload Beans
After cleaning, set the grind to a slightly coarser setting if it was very fine. Finer grinds are more prone to clogging, especially if beans are stale. Reload fresh, high-quality beans into the hopper, filling it no more than three-quarters full to prevent overloading and jamming. Reassemble the grinder components carefully, ensuring everything is securely in place.
Run a Cleaning Cycle and Test
Turn on your Breville Bambino Plus and run a few grind cycles without coffee to clear out any remaining debris. If your machine has a cleaning function, use it according to the manufacturer’s instructions. Afterward, test by brewing a shot to ensure the grinder operates smoothly and without blockage. Repeat cleaning if necessary, and consider performing this routine weekly to prevent future clogs.
