Identify the Cause of the Grinder Clog

The first step is to determine whether the clog is caused by stale beans, improper grind size, or leftover coffee oils. Signs include unusual noises during grinding, uneven coffee grounds, or the grinder stopping mid-process. Check the bean freshness—use high-quality, fresh beans for optimal grinding. Also, observe if the grind setting is too fine, which can overload the grinder and cause jams. Regularly inspecting and cleaning the burrs can help identify if buildup is causing the issue.

Disassemble and Clear the Grinder

  1. Turn off and unplug your Breville Bambino Plus to ensure safety.
  2. Remove the bean hopper by gently lifting it off the machine.
  3. Locate the burr grinder assembly and carefully remove any visible coffee grounds or blockages.
  4. Use a small brush or a soft cloth to clean around the burrs and inside the grinder chamber.
  5. If needed, gently tap the burrs to dislodge stubborn grounds, but avoid using metal tools that could damage the burrs.

Clean and Maintain the Grinder

Regular cleaning prevents oil and coffee residue buildup that can cause clogs. Use a dedicated espresso machine cleaning tablet, such as the Breville BEC250, designed to dissolve and remove oils from the grinder and other parts. Follow the manufacturer’s instructions for cleaning tablets—usually, you run the tablet through the grinder as if it were beans, which helps break down stubborn residues and oils.

Additionally, inspect the burrs for wear and replace if necessary. Always ensure the grinder is dry before reassembling.

Adjust Grind Size and Usage Habits

Fine grind settings are more prone to clogging, especially if beans are stale or oily. Adjust the grind to a slightly coarser setting and see if that alleviates the issue. Avoid overloading the hopper—use the recommended amount of beans for each grind cycle. Also, switch to fresh beans regularly, ideally within a month of opening, to ensure consistent grinding performance.

Reassemble and Test Your Machine

  1. Replace the burrs carefully and reattach the hopper securely.
  2. Run a test grind without coffee to ensure the grinder turns smoothly.
  3. Check for any unusual noises or jams.
  4. Make a small espresso shot to verify proper operation and grind consistency.

If the clog persists, repeat the cleaning process or consider replacing worn burrs or the grinder assembly if necessary.
