Key Takeaways
| Consistent Grind Size | Use the correct grind setting to prevent clogging. |
| Fresh Coffee Beans | Always grind fresh, high-quality beans. |
| Regular Cleaning | Clean the grinder and machine components regularly. |
| Proper Dosage | Avoid overloading the grinder to prevent jams. |
Check and Adjust Your Grind Size
- Turn on your Breville Bambino Plus and access the grinder settings. Refer to your user manual for exact instructions, but typically, you can adjust the grind size via the control knob or digital interface.
- Set the grind to a coarser setting if you notice frequent clogs. A grind that’s too fine can cause excessive pressure buildup and blockages.
- Run a test grind with a small amount of coffee. Observe the flow; if the coffee is coming out too slowly or not at all, further coarsen the grind.
Use Fresh, Properly Roasted Coffee Beans
Stale or oily coffee beans are a common cause of grinder clogs. Old beans tend to produce more fines (tiny coffee particles) which can clog the grinder burrs or chute.
Always use fresh beans roasted within the last few weeks. Store beans in an airtight container away from light and humidity to maintain their quality. When grinding, avoid overfilling the hopper—this can increase the risk of jams and uneven grinding.
Regularly Clean the Grinder and Machine Components
- Unplug the machine before cleaning. Remove the bean hopper and any accessible burrs, following your user manual instructions.
- Use a soft brush or vacuum to clear out coffee grounds and fines from the chute and burr area.
- For deeper cleaning, consider using Breville BEC250 Espresso Machine Cleaning Tablets, designed to remove coffee oils and residues from your machine, which can contribute to clogging if buildup occurs over time.
Clear and Remove Any Blockages
If you suspect a jam, gently disassemble the grinder components. Carefully remove any stuck coffee grounds or debris using a non-metallic tool to avoid damaging burrs.
Reassemble the parts securely and run a few test grinds without coffee to ensure the pathway is clear and the grinder runs smoothly.
Prevent Future Clogs with Proper Usage and Maintenance
Implement routine cleaning, using fresh beans, and adjusting grind settings as needed. Avoid grinding excessively fine or overloading the hopper, which can strain the grinder.
Consider supplementing your maintenance with replacement water filters, such as Breville Charcoal Filters or Possiave Water Filters, to ensure water quality and prevent scale buildup that can affect overall machine performance.
