Understanding the Causes of Grinder Clogs
Grinder clogs in your Breville Bambino Plus can occur for several reasons. The most common cause is the accumulation of coffee oils and residues that harden over time, especially if the machine isn’t cleaned regularly. Stale coffee grounds can also compact and jam the burrs, preventing proper grinding. Additionally, debris such as small coffee beans or foreign objects accidentally entering the grinder can cause blockages.
Mineral buildup from tap water, if not descaled periodically, can contribute to the clogging of internal components, including the grinder mechanism. Understanding these causes helps in implementing preventive measures like regular cleaning, descaling, and using fresh coffee beans.

Preparing for the Fix: Safety and Tools
Before attempting any fixes, safety is paramount. Always unplug your Breville Bambino Plus to avoid electrical shock or accidental activation during maintenance. Gather necessary tools such as a soft brush, a microfiber cloth, and if available, the cleaning tablets recommended for Breville machines.
Consult your user manual for specific disassembly instructions and ensure you are working on a clean, flat surface. If your machine is still under warranty or you’re unsure about opening it, consider contacting a professional technician.
Step-by-Step Guide to Clearing a Grinder Clog
- Unplug the machine and remove the bean hopper to access the burrs.
- Inspect the burrs and grinder chamber for visible blockages or debris.
- Gently remove any stuck coffee grounds using a soft brush or a small vacuum designed for electronics.

- Reassemble the grinder and run a cleaning cycle with fresh beans or cleaning tablets if recommended.
- Test the grinder by running a small amount of coffee through to ensure smooth operation.
- Perform regular maintenance to prevent future clogs, including descaling and cleaning.
Tips for Preventing Future Grinder Clogs
- Use fresh, high-quality coffee beans and avoid oily beans that can cause buildup.
- Clean the burrs and grinder chamber every 1-2 months, especially if you notice inconsistent grinding.
- Descale your machine regularly with recommended descaling tablets to prevent mineral deposits.

When to Seek Professional Help
If you’ve followed all troubleshooting steps and your grinder remains clogged or the machine exhibits persistent issues, it is advisable to consult a professional technician. Persistent clogs may indicate deeper mechanical problems or damage that requires specialized repair. Avoid forcing parts or using excessive force during cleaning, as this can cause further damage.
