Understanding the Causes of Grinder Clogs
Grinder clogs in your Breville Bambino Plus typically result from a few common issues. Stale beans or beans with excess oils can cause residues to stick inside the burrs, leading to blockages. Additionally, grinding too many beans at once or using beans that are too hard can exert excessive pressure, causing jams.
Over time, coffee residues and oils build up inside the grinder, especially if the machine isn’t cleaned regularly. This buildup can reduce the clearance between burrs, impeding the grinding process and eventually causing a clog. Lastly, using incompatible or old cleaning accessories may contribute to improper cleaning, increasing the risk of blockages.

- Clear the burrs: Use a plastic or wooden tool to gently dislodge any stuck coffee grounds or residues. Never use metal tools that could damage the burrs.
- Clean the burrs and chute: Use a brush or a specific cleaning brush to sweep away residual coffee grounds. If you have access to cleaning tablets like the Breville BEC250, dissolve and run a cleaning cycle as per instructions.

- Grind in smaller batches: Avoid overloading the hopper to reduce pressure on the burrs.
- Clean regularly: Use appropriate brushes and cleaning tablets designed for Breville machines.
