Identifying the Cause of Your Grinder Clog
Before attempting to fix a grinder clog, it’s important to determine the root cause. Common signs include inconsistent grind size, difficulty in grinding, or a complete halt in coffee production. Check if your beans are stale or if you’ve overfilled the hopper, as these factors can lead to blockages.
Additionally, inspect the grinder burrs for buildup of coffee grounds or debris. If you notice any unusual noises or grinding resistance, it indicates a clog or mechanical issue that needs addressing.

Step-by-Step Guide to Clearing a Grinder Clog
- Turn Off and Unplug Your Machine: Safety first. Always disconnect your espresso machine from power to prevent accidents.
- Remove the Bean Hopper: Carefully lift off the hopper, empty any remaining beans, and set aside.
- Access the Burrs: Follow your Breville model’s manual to remove the top burr or grinder components. Usually, this involves unscrewing or unlatching parts.
- Clear Blockages: Use a small brush or a soft cloth to remove coffee grounds and debris from the burrs and chute. Avoid using water or liquids that could damage internal components.
- Check for Damage: Inspect the burrs and other parts for wear or damage. Replace if necessary.
- Reassemble and Test: Carefully reattach all parts, refill the hopper with fresh beans, and plug in your machine. Run a test grind to ensure smooth operation.
Preventing Future Grinder Clogs
Prevention is key to maintaining optimal performance. Regularly clean your grinder components, ideally once a month, using a brush or grinder cleaning tablets designed for Breville machines. Always use fresh, high-quality beans and avoid overfilling the hopper, as this can cause jams.
Adjust your grind size to a slightly coarser setting if you notice frequent clogs. Fine grinds are more prone to blockage, especially with stale or oily beans.
Additional Tips & Safety Warnings
- Use Proper Tools: Always use the recommended tools, such as a small brush, and avoid sharp objects that could damage burrs.
- Handle Parts Carefully: Burrs are sharp and can cause injury. Wear protective gloves if necessary.
- Disconnect Power: Never work on your machine while it is plugged in to prevent electrical hazards.
- Consult the Manual: Refer to your Breville Bambino Plus user manual for specific disassembly instructions.
- Seek Professional Help: If you’re uncomfortable performing these steps, contact a qualified technician to avoid damaging your machine.
