Understanding Why Your Grinder Clogs

Grinder clogging in your Breville Bambino Plus typically results from factors like residual coffee oils, stale beans, or improper grind settings. Over time, coffee oils and fine particles can accumulate inside the burrs and grind pathway, leading to blockages that restrict coffee flow. Additionally, using beans that are too oily or grinding too fine can increase the likelihood of jams. Recognizing these causes helps in preventing future clogs and maintaining optimal performance.

Prevention Tips to Minimize Clogging

  • Use Fresh Coffee Beans: Old or stale beans tend to produce more oils and fines that lead to buildup.
  • Adjust Grind Size: Avoid grinding too fine; a medium to slightly coarse setting can reduce jams.
  • Regular Cleaning: Clean the burrs and grind pathway weekly with a brush or cleaning tablets.
  • Store Beans Properly: Keep beans in an airtight container away from moisture and heat.

Step-by-Step Guide to Clear a Grinder Clog

  1. Turn Off & Unplug: Always disconnect your machine before cleaning to ensure safety.
  2. Remove the Bean Hopper: Carefully lift out the hopper, empty any remaining beans, and clean the area.
  3. Access the Burrs: Remove the upper burr holder following your machine’s manual instructions.
  4. Clear Obstructions: Use a small brush or a dedicated cleaning tool to dislodge any coffee grounds or oils.
  5. Clean with Tablets (Optional): Use a Breville coffee machine cleaning tablet, following the instructions, to dissolve residue inside the grinder.
  6. Reassemble & Test: Put everything back together, fill with fresh beans, and run a test grind to verify smooth operation.

Additional Tips & Warnings

Avoid Forcing Parts: Do not force burrs or other components, as this can cause damage. Follow proper disassembly instructions.

Use Proper Cleaning Products: Only use cleaning tablets made for espresso machines, such as Breville BEC250, to avoid corrosion or damage.

Frequency of Cleaning: Regularly clean your grinder every 1-2 weeks, depending on usage, to prevent buildup.

Warning: Always unplug the machine before cleaning. Avoid using water directly on internal parts to prevent electrical issues.
