Clear the Grinder Clog
- Open the bean hopper lid and carefully remove the beans. If beans are oily or sticky, wipe the hopper with a dry cloth.
- Inspect the burrs and grinder chamber for visible blockages or grounds jammed inside.
- Gently use a small brush or the cleaning tool provided with your machine to dislodge stuck grounds.
- If grounds are stubborn, turn the grinder manually (if possible) or gently tap the machine to loosen debris. Do not use metal tools to avoid damage.
Clean and Maintain the Grinder
Regular cleaning prevents future clogs. Use a manufacturer-approved cleaning tablet such as the Breville BEC250 Espresso Machine Cleaning Tablets, which are designed to remove coffee oils and residues safely.
After clearing the clog, run a cleaning cycle with the tablet following the manufacturer’s instructions. This helps dissolve any oily buildup that can cause grinding issues.
Adjust Grind Settings and Coffee Selection
- Ensure your grind size is set appropriately—generally medium to slightly coarse for espresso machines like the Bambino Plus.
- A grind that’s too fine increases resistance, leading to clogging. Adjust the grind to a slightly coarser setting if frequent jams occur.
- Use fresh, dry coffee beans. Oily beans can stick and cause blockages, so consider switching to a different roast if problems persist.
Reassemble and Test
Once cleaned and adjusted, reassemble the hopper and any removed parts. Plug in the machine, fill the water tank, and run a test espresso cycle.
Observe the grinder during operation. If it runs smoothly without jamming, your fix was successful. If issues continue, repeat cleaning or consider replacing worn burrs or consulting a professional.
