Identify the Cause of the Clog
Start by examining the grinder and coffee grounds. If you notice a buildup of oily or stale grounds, or if the grinder motor sounds strained, these are signs of clogging. Also, check if the coffee beans are fresh and dry, as moisture and old beans increase the risk of jams. Confirm that your water filters are up to date, because impurities can cause blockages in the grinder mechanism.

Turn Off and Unplug the Machine
- Ensure the espresso machine is turned off and unplugged from the power outlet.
- Wait a few minutes to let internal components cool if recently used.
- Remove the bean hopper and the portafilter to access the grinder area safely.
Clean the Grinder and Burrs
- Use a soft brush or a dedicated grinder cleaning brush to gently remove loose coffee grounds from the burrs and chute.
- If your machine recommends cleaning tablets, consider using Breville BEC250 Espresso Machine Cleaning Tablets for thorough cleaning, following manufacturer instructions.
- Do not use water or liquids directly on the grinder parts to prevent damage.
Remove and Clear Any Obstructions
- Carefully remove the bean hopper and inspect the burr area for lodged grounds or debris.
- If you see a jam, gently dislodge it using a plastic or wooden tool—avoid metal tools to prevent scratching.
- Reassemble the hopper and run a small amount of coffee through the grinder to check flow and ensure smooth operation.
Replace Water Filters and Check Water Quality
Impurities from tap water can contribute to clogging. Replace your Breville charcoal filters or Possiave water filters if they are nearing the two-month replacement period. Use filtered water to reduce mineral buildup and oily residues that can clog the grinder over time.
Test and Maintain Regularly
After cleaning, run a few test grinds with fresh coffee beans. If the problem persists, repeat the cleaning process or consider replacing worn burrs. Regular maintenance, including using cleaning tablets like Breville BEC250, will keep your grinder and machine in optimal condition and prevent future clogs.
