Common Causes of Grinder Clogs in Breville Bambino Plus
Understanding why your grinder gets clogged is the first step to fixing it. The most common causes include using old or stale coffee beans which can gum up the burrs, grinding too fine which causes buildup and jams, and insufficient cleaning which allows coffee oils and residues to accumulate. Additionally, a sudden change in grind size or using inconsistent beans can contribute to blockages. Recognizing these causes helps you take proactive steps to prevent future clogs and maintain optimal espresso quality.

Preparing to Fix the Grinder Clog
- Turn off and unplug your Breville Bambino Plus to ensure safety during cleaning and troubleshooting.
- Remove the water tank and drip tray to access the grinder area more easily.
- Gather necessary tools: a small brush, cleaning cloth, and the recommended cleaning tablets if needed.
Having all tools ready before starting makes the process smoother and reduces the risk of damaging internal parts.
Step-by-Step Guide to Clearing a Grinder Clog
- Remove the bean hopper: twist and lift to access the burr chamber.
- Inspect the burrs for any stuck coffee grounds or debris. Use a small brush to gently dislodge blockages.
- If grounds are jammed, carefully tap or gently shake the burr assembly to loosen stuck particles.
- For stubborn clogs, you can run a cleaning tablet (such as Breville BEC250 or the Replacement Espresso Cleaning Tablet) through the grinder following the manufacturer’s instructions.
- Reassemble the grinder: ensure all parts are properly seated and secure.
- Run a test grind with fresh coffee beans to check if the clog has cleared.
If the grinder still jams, repeat the cleaning process or consider contacting Breville customer support for advanced troubleshooting.
Tips for Preventing Future Grinder Clogs
- Use fresh, high-quality coffee beans to avoid oily residues that cause buildup.
- Adjust the grind size to slightly coarser if you notice frequent jams, especially with oily beans.
- Clean your grinder regularly—at least once a month—to remove coffee oils and residues.
- Run a cleaning cycle with cleaning tablets periodically to maintain internal cleanliness.
- Store beans in a sealed container away from moisture and air to maintain freshness.
Consistent maintenance and proper bean storage are key to preventing clogs and ensuring your espresso machine delivers the best flavor every time.
Safety Tips and Warnings
- Always unplug your machine before disassembling or cleaning to avoid electrical hazards.
- Handle burrs and internal parts carefully to prevent damage or injury.
- Use only manufacturer-approved cleaning products and tablets to avoid corrosion or damage.
- Do not force parts apart; if they resist, consult the user manual or contact Breville support.
Following safety precautions ensures a safe, effective cleaning process that prolongs your machine’s lifespan.
