Identify the Cause of the Grinder Clog
- Start by inspecting the grinder chamber and chute for visible blockages. Remove the bean hopper and look for stuck grounds or debris.
- Check if the grind size is set too fine, which can cause grounds to compact and clog.
- Ensure you’re using high-quality, fresh beans with low oil content, as oils can clog grinders over time.
- If the machine’s noise or grinding feels irregular, it may be a sign of internal buildup or worn burrs.

Clean the Grinder and Chute Thoroughly
- Turn off and unplug the machine before cleaning.
- Remove the bean hopper and empty any remaining beans.
- Use a soft brush or a dedicated grinder cleaning brush to clear out grounds from the burrs and chute.
- If your machine supports it, run a cleaning cycle with grinder cleaning tablets, such as the Breville BEC250 or the Replacement Espresso Cleaning Tablet, to dissolve oil and residues.
- Reassemble the hopper and run a test grind to check if the clog persists.
Adjust Grind Settings and Use Fresh Beans
After cleaning, set the grind size to a slightly coarser setting to prevent grounds from compacting. Avoid overly fine settings that can cause jams.
Use fresh, low-oil beans for grinding. Oily beans tend to clog grinders more often and can cause buildup that leads to frequent jams.
Perform Regular Maintenance
- Schedule weekly cleaning of the grinder with a soft brush and occasional use of cleaning tablets.
- Replace water filters periodically, such as the Breville Charcoal Filters, to ensure water quality and reduce mineral buildup that may affect grinding.
- Use the recommended cleaning tablets regularly, like the Breville BEC250, to keep internal components clean and functioning well.
Troubleshooting Persistent Clogs
If clogging persists after cleaning and adjusting settings, inspect the burrs for wear. Worn burrs can cause uneven grinding and jams. Replacing burrs or consulting a professional technician may be necessary.
Ensure the machine’s internal pathways are free of debris and that the grinder motor is functioning smoothly. Overloading the hopper or forcing the grinder can also cause jams, so operate within recommended bean quantities.
