Identify and Clear the Clog
- Turn off and unplug your Breville Bambino Plus to ensure safety.
- Access the grinder compartment by removing the bean hopper according to the user manual.
- Look inside the grinding chamber for any visible blockages or coffee grounds stuck in the burrs.
- If you see a clog, gently tap or brush away loose grounds using a small brush or toothbrush.
If grounds are hardened or stuck, proceed with cleaning to prevent future issues.
Clean the Grinder Components
Regular cleaning helps prevent buildup that causes clogging. Follow these steps:
- Remove the burrs carefully if your model allows, following the manual instructions.
- Use a soft brush or cloth to remove residual coffee grounds from the burrs and chamber.
- Place the burrs back securely, ensuring they are aligned correctly.
- Run a cleaning cycle using Breville cleaning tablets (like the BEC250) to dissolve oils and residues inside the grinder.
Using official cleaning tablets ensures thorough cleaning without damaging internal parts.
Adjust Grind Size and Beans
Sometimes, a clog occurs because the grind size is too fine or the beans are stale. To prevent this:
- Set the grinder to a slightly coarser setting—avoiding extremely fine grounds which can jam the grinder.
- Use fresh, high-quality coffee beans, preferably roasted within the last few weeks.
- Avoid overfilling the hopper; grind smaller amounts at a time.
Consistent, proper grind size reduces the risk of clogging and improves espresso quality.
Reassemble and Test the Machine
Once cleaned and adjusted:
- Reassemble all parts securely, ensuring burrs and hopper are properly installed.
- Plug in the machine, turn it on, and run a test grind.
- Observe if the grind is smooth and if the machine operates without jamming.
If the problem persists, repeat cleaning or consider replacing worn burrs or components.
Prevent Future Clogs
To keep your Breville Bambino Plus running smoothly:
- Clean the grinder regularly—ideally after every few uses.
- Use fresh beans and avoid grinding excessively fine grounds.
- Perform routine maintenance as recommended in the user manual.
Consistent care will extend your machine’s lifespan and ensure consistent coffee quality.
