Identifying Grinder Clogs in Your Breville Bambino Plus
Signs of a grinder clog include a sudden halt in coffee grounds output, unusual noises during grinding, or a noticeable decrease in grind consistency. If your espresso machine is not dispensing grounds or the grinder is making grinding sounds without coffee coming out, these are clear indicators of a potential jam.
In my experience, a common cause is using beans that are too dark or oily, which can clog the burrs or channel within the grinder. Additionally, stale beans tend to clump and cause blockages. Regularly observing your grind output and noise levels can help you catch issues early, avoiding more serious damage.

Step-by-Step Guide to Fix a Grinder Clog
- Turn off and unplug the machine: Safety first—ensure the machine is powered down before attempting any maintenance.
- Remove the bean hopper: Carefully lift out the hopper, emptying any remaining beans.
- Clear the burrs: Use a brush or a soft cloth to gently remove coffee residue around the burrs and chute. If available, use a dedicated cleaning brush for espresso grinders.
- Inspect for obstructions: Check for jammed beans or debris lodged in the grinding chute or burrs. Remove any visible blockages carefully.
- Clean the grinder: Wipe all accessible parts with a damp cloth. Avoid using harsh chemicals that could damage the machine.
- Reassemble and test: Put everything back together, refill with fresh beans, and run a test grind to ensure smooth operation.
If the clog persists, consider performing a deep cleaning with compatible cleaning tablets or seeking professional servicing if needed.
Preventing Future Clogs in Your Breville Bambino Plus
Prevention is better than cure. Regularly cleaning your grinder with appropriate products, like the Breville BEC250 Espresso Machine Cleaning Tablets, helps remove built-up oils and coffee residues that can cause blockages. Using fresh, medium grind beans also minimizes the risk of clogging, as overly oily or fine beans are more prone to jamming.
Adjusting your grind size to a slightly coarser setting can improve flow and reduce strain on the grinder. Additionally, avoid grinding large quantities at once; small, consistent doses prevent overloading the burrs and ensure a smoother operation.
When to Seek Professional Help
If you’ve followed the troubleshooting steps but the grinder remains clogged or the noise persists, it might be time to consult a professional technician. Persistent clogs could indicate worn burrs or internal damage that requires replacement or specialized cleaning.
Regular servicing by authorized repair centers can extend the life of your machine and ensure optimal performance. Remember, attempting complex repairs beyond basic cleaning can risk voiding your warranty or damaging the device further.
Additional Maintenance Tips for Your Breville Bambino Plus
Besides clearing clogs, routine maintenance includes replacing charcoal water filters (such as the Breville Charcoal Filters or Possiave Water Filters) every two months to ensure water quality and taste. Keep the water reservoir clean and dry, and descale the machine periodically using compatible descaling tablets to prevent mineral buildup.
Using high-quality, fresh beans and storing them properly also help maintain consistent grind quality and flavor. Investing in dedicated cleaning products designed for Breville espresso machines can simplify maintenance and prolong your machine’s lifespan.
