Step 1: Turn Off and Unplug Your Machine
Before beginning any troubleshooting or cleaning, ensure your Breville Bambino Plus is turned off and unplugged. This prevents accidental activation or electrical hazards during maintenance.
Step 2: Remove and Clean the Portafilter and Grinder Components
- Detach the portafilter and empty any remaining coffee grounds.
- Remove the hopper and the burr grinder assembly following the manufacturer’s instructions in your user manual.
- Use a soft brush or a dedicated cleaning brush to sweep out residual coffee grounds from the burrs and chute.
- Wipe down all accessible parts with a damp cloth. Avoid using harsh chemicals.
- Reassemble the grinder components carefully, ensuring they are properly aligned.
Step 3: Clear Any Blockages in the Grind Path
If you notice a jam or resistance when grinding, use a small, non-metallic tool (like a plastic toothpick) to gently dislodge any stuck coffee grounds. Keep the grind pathway clear to prevent future clogs.
Step 4: Check and Adjust Your Grind Size
Fine grind settings are more prone to clogging. Adjust the grind to a slightly coarser setting and test the grinder. Proper grind size ensures smooth operation and prevents grounds from compacting and blocking the chute.
Step 5: Perform Regular Deep Cleaning and Descaling
- Use a cleaning tablet designed for Breville machines, such as the Breville BEC250 or the Replacement Espresso Cleaning Tablet, to remove oils and residues.
- Follow the cleaning tablet instructions carefully, running the cleaning cycle as recommended by the manufacturer.
- Descaling the machine periodically with appropriate descaling agents prevents mineral buildup that can contribute to clogging.
Tips and Warnings
- Tip: Always use fresh, high-quality coffee beans stored in airtight containers to minimize stale grounds that cause clogging.
- Warning: Never use metal tools inside the grinder, as they can damage burrs or internal parts.
- Make sure all components are dry and correctly reassembled before plugging in and turning on your machine.
- Follow the manufacturer’s instructions for cleaning and maintenance to avoid voiding warranties.
