Step 1: Turn Off and Unplug Your Machine
Before starting any troubleshooting, ensure your Breville Bambino Plus is turned off and unplugged from the power source. This is essential for your safety and prevents any accidental damage during cleaning or inspection.
Allow the machine to cool down if recently used, especially around the grinder area, to avoid burns or injury.
Step 2: Remove and Empty the Bean Hopper
- Open the bean hopper lid and carefully remove the hopper from the machine.
- Empty any leftover beans, especially if they are stale or dried out, as these can cause clogging.
- Clean the hopper with a damp cloth to remove dust or oil residues.
- Ensure the hopper is completely dry before reattaching to prevent moisture from affecting the beans or grinder.
Step 3: Check and Adjust the Grind Size
One common cause of grinder clogging is using an excessively fine grind. Consult your Breville Bambino Plus manual to locate the grind size dial or setting.
Adjust the grind to a slightly coarser setting if it’s too fine. This helps prevent grounds from compacting and causing blockages.
Run a small amount of beans through the grinder to test if the clog persists after this adjustment.
Step 4: Clean the Grinder and Burrs
- Use a dedicated grinder cleaning tablet, such as the Breville BEC250 or similar, to remove oil buildup and coffee residues.
- Follow the tablet instructions—generally, you place the tablet in the hopper and run the grinder to dissolve and clean the burrs.
- Periodically, manually brush the burrs with a small, soft brush to dislodge any stuck grounds.
- Wipe the exterior and around the burr chamber with a dry cloth.
Regular cleaning reduces oil and residue buildup, which are major causes of clogging over time.
Step 5: Reassemble and Test the Machine
Once cleaning and adjustments are complete, reassemble the bean hopper, ensuring it is securely in place.
Plug the machine back in and run a test grind with fresh beans. Observe if the grinder operates smoothly without clogging.
If the problem persists, consider reducing the grind size further or inspecting the burrs for damage or misalignment.
Additional Tips and Warnings
- Use fresh beans to prevent stale grounds that can cause clogging.
- Always follow the manufacturer’s instructions for cleaning and maintenance.
- Avoid grinding excessively oily beans, which can clog the burrs and internal pathways.
- Do not use harsh chemicals or abrasive tools to clean the grinder.
- If you notice persistent mechanical issues, contact Breville customer support for professional assistance.
