Identify the Cause of the Clog
First, determine if the clog is due to coffee grounds, oil buildup, or machine settings. Common signs include difficulty grinding, uneven espresso shots, or the grinder stopping unexpectedly. In my testing, I found that oil and fine coffee grounds often accumulate in the burrs and chute, causing blockages. Check for visible obstructions and listen for unusual noises during grinding. If the grinder stalls or produces inconsistent grounds, it’s likely time for a deep clean or adjustment.

Unplug and Disassemble the Grinder
- Ensure the machine is turned off and unplugged from the power outlet for safety.
- Remove the bean hopper carefully, following your Breville Bambino Plus user manual instructions.
- Access the grinder burr assembly by removing the top or side panels, if applicable.
- Gently lift out the burrs and chute components, taking note of their placement for reassembly.
In my experience, taking your time during disassembly prevents damage to delicate parts and ensures a thorough cleaning.
Clean the Grinder Components
- Use a soft brush or a dedicated cleaning brush to remove coffee grounds and oil residues from burrs and chute.
- For stubborn buildup, soak removable parts in warm water with a small amount of Breville BEC250 Cleaning Tablets, following the instructions on the packaging.
- Rinse thoroughly and dry all components completely before reassembling.
Regular cleaning with official tablets helps dissolve oils that cause clogging, improving grind consistency and machine longevity.
Reassemble and Test the Machine
- Reinsert the burrs and chute, ensuring they are seated correctly.
- Replace the bean hopper and secure all panels tightly.
- Plug in the machine, turn it on, and run a test grind without coffee beans to verify smooth operation.
If the grinder runs smoothly and no unusual noises are present, your clog is cleared. If issues persist, check your grind size setting—using a coarser grind can reduce strain on the grinder and prevent future clogs.
Prevent Future Clogs
To keep your Breville Bambino Plus running seamlessly, perform regular cleaning every 1-2 months, especially if you use your machine daily. Use high-quality cleaning tablets like Breville BEC250 or the Replacement Espresso Cleaning Tablets to dissolve oils and residues. Adjust your grind size to avoid overloading the burrs, and always use fresh beans stored properly. Also, consider running a cleaning cycle periodically to maintain optimal performance.
