Identify the Cause of the Clog
The first step in fixing a grinder clog is diagnosing the cause. Common issues include using beans that are too oily or moist, which can clog the burrs and chute, or accumulated grounds from previous use. Check for signs like slow grinding, uneven grounds, or a jammed burr mechanism. If the grinder appears to be jammed or making unusual noises, it’s likely blocked by grounds or oil buildup. Identifying the cause helps determine whether cleaning, adjusting grind size, or replacing parts is necessary.

Disassemble and Clean the Grinder
- Unplug the machine and remove the bean hopper.
- Check for any visible grounds or oil residue around the burrs and chute.
- Use a soft brush or a dedicated cleaning tool to gently remove lodged grounds.
- If available, use Breville cleaning tablets (such as the BEC250) to dissolve oils and residues—follow tablet instructions for safe use.
- Reassemble the grinder carefully, ensuring all parts are correctly fitted.
Adjust Grind Settings and Beans
After cleaning, review your grind settings. A finer grind can cause clogging, especially with oily beans. Set the grind to a slightly coarser setting and use high-quality, dry beans to minimize oil and moisture. Experiment with small adjustments and test run to find the optimal setting that prevents clogging while maintaining espresso quality.
Perform Routine Maintenance
Regularly clean your machine’s water filters, shower screens, and filter baskets. Use appropriate cleaning tablets as part of your maintenance schedule—this prolongs the lifespan of your espresso machine and keeps the grinder functioning smoothly. Descaling the machine periodically also reduces mineral buildup that can impact grinding and extraction.
Prevent Future Clogs
To avoid recurring grinder issues, always use fresh, dry beans and avoid overpacking the hopper. Keep the bean container clean and free from dust or moisture. Adjust your grind size appropriately and run occasional cleaning cycles using recommended cleaning products. These practices will help your Breville Bambino Plus operate efficiently for years to come.
