Understanding the Causes of Grinder Clogs
Grinder clogs in your Breville Bambino Plus typically happen due to several common reasons. Stale coffee beans can produce more oily residues, which tend to stick and cause blockages. Over-tamping the coffee grounds can also restrict the flow of grounds, leading to pressure build-up and clogging. Additionally, accumulated coffee debris and oils inside the grinder or burrs can cause blockages over time if not cleaned regularly.
Identifying the root cause is essential before attempting repairs. Regularly inspecting your beans, tamping pressure, and cleaning schedule can prevent many clogging issues.

Step-by-Step Guide to Clear a Grinder Clog
- Remove the hopper and grind burrs following your machine’s user manual instructions.
- Inspect the burrs and grind chamber for any stuck coffee grounds or debris.
- If grounds are stuck, gently tap or brush them out, avoiding force that could damage the burrs.
- Use a soft brush or a cleaning cloth to clean residue from the burrs and grinding chamber thoroughly.
- Reassemble the burrs and hopper securely.

Tips to Prevent Future Clogs

- Clean the grinder regularly, ideally weekly, especially if you grind frequently.
- Consider using cleaning tablets periodically to dissolve oils and residues.
- Inspect and replace charcoal filters if water impurities are causing buildup.
When to Seek Professional Help
If you’ve followed all cleaning and troubleshooting steps and the grinder still clogs, it might be time to contact a professional or authorized service center. Persistent clogs could indicate a mechanical issue or worn burrs that require expert attention.
