Step 1: Unplug and Prepare Your Machine
- Ensure your Breville Bambino Plus is turned off and unplugged to avoid electrical hazards.
- Remove the bean hopper and empty any remaining beans.
- Clean the hopper and surrounding areas with a dry cloth to remove dust and residual coffee oils.
Step 2: Access the Grinder and Check for Obstructions
Remove the top cover of the grinder (refer to your user manual if needed). Inspect the burrs and grinding chamber for any jammed beans, coffee grounds, or debris.
If you notice a bean jam, carefully remove the obstruction with a soft brush or tweezers. Be gentle to avoid damaging the burrs.
Step 3: Clean the Grinder Components
- Use a soft brush or a vacuum designed for small appliances to remove coffee grounds and oil residues from the burrs and chamber.
- Run a cleaning cycle with Breville-approved cleaning tablets (such as BREVILLE BEC250) to dissolve oils and residues inside the grinder.
- Follow the tablet instructions for dissolution time, typically about 10-15 minutes, then run the grinder to flush out loosened residues.
Step 4: Adjust the Grind Size and Test
Set the grind size to a slightly coarser setting—this helps prevent future clogs. Reassemble the grinder, refill the hopper with fresh beans, and run a test grind.
If the machine still clogs, repeat the cleaning process or consider reducing the amount of beans loaded at once.
Step 5: Prevent Future Clogs with Proper Maintenance
- Regularly clean the grinder with appropriate cleaning tablets or brushes.
- Use fresh, high-quality coffee beans stored in an airtight container.
- Avoid overloading the hopper; grind smaller amounts if necessary.
- Perform routine descaling and filter replacement to maintain overall machine health.
