Identify the Signs of Grinder Clogging
Before attempting fixes, recognize the signs of a grinder clogging. Common symptoms include the grinder not turning, unusual noises, or inconsistent grind size. You might also notice that beans are not being fed properly into the burrs, causing the machine to halt or produce weak espresso.
If you observe these issues, it’s time to perform a thorough cleaning and inspection of the grinder components.
Step 1: Turn Off and Unplug Your Machine
- Ensure the espresso machine is turned off and unplugged from the power outlet.
- Allow the machine to cool down for at least 15 minutes to avoid burns or damage.
- Remove the bean hopper carefully, following your user manual instructions.
Step 2: Remove and Clean the Burr Grinder
- Gently remove the burr grinder assembly as per your machine’s manual.
- Inspect for bean debris, oily residues, or blockages.
- Use a small brush or the cleaning brush included with your machine to clear out residual coffee grounds.
- For more thorough cleaning, consider using official Breville cleaning tablets, like the Breville BEC250 or the Replacement Espresso Cleaning Tablet, to dissolve oils and residues.
Step 3: Use Cleaning Tablets for Deep Cleaning
Place one cleaning tablet into the grinder chamber and run a cleaning cycle if your machine supports it. Alternatively, follow the instructions for manual cleaning with tablets to dissolve oils inside the burrs.
This process helps remove oily buildup that often causes clogging, especially with oily or old beans.
Step 4: Reassemble and Test
- Carefully reassemble the burr grinder, ensuring all parts are aligned correctly.
- Refill the bean hopper with fresh, dry beans—preferably medium roast, non-oily beans for better grinding performance.
- Turn the machine on, run a test grind cycle, and observe if the issue persists.
Tips and Warnings for Preventing Future Clogs
- Use high-quality, fresh beans—oily beans are more prone to causing clogs.
- Regularly clean your grinder with recommended tablets or brushes, ideally every 1-2 months.
- Avoid overfilling the bean hopper beyond the recommended level.
- Follow the manufacturer’s maintenance schedule to keep your machine in optimal condition.
Warning: Never force open or disassemble parts that are not designed for user maintenance. Doing so may void your warranty or cause damage.
