Identify the Signs of a Grinder Clog
Before attempting repairs, recognize if your Breville Bambino Plus is experiencing a grinder clog. Common signs include difficulty in grinding beans, unusually loud noises during operation, or the machine stopping abruptly. Sometimes, you may notice that the coffee isn’t extracting properly, or the grinder motor stalls. These symptoms point toward a blockage that needs addressing.
In my experience, frequent clogs often result from oily coffee grounds or stale beans, which can gum up the grinder burrs and chute. If your machine is showing these signs, it’s time to clean and clear the grinder pathway.

Step 1: Turn Off and Unplug the Machine
- Ensure your Breville Bambino Plus is completely powered off and unplugged from the electrical outlet. This is vital for your safety before performing any maintenance or cleaning.
- Remove the water reservoir and drip tray to access the grinder area. If your model has a bean hopper, carefully remove it as well.
Step 2: Clear Out Loose Grounds
Using a soft brush or a small vacuum attachment, gently remove any loose coffee grounds from the bean hopper, chute, and grinder burrs. This initial cleanup can often resolve minor blockages.
Be cautious not to damage sensitive components. If grounds are stuck tightly, proceed to the next step for a more thorough cleaning.
Step 3: Use Cleaning Tablets for Deep Cleaning
- Take a Breville BEC250 Espresso Machine Cleaning Tablet or the Replacement Espresso Cleaning Tablet, designed for Breville models.
- Follow the instructions on the package: typically, you place the tablet in the grinder or designated cleaning slot and run a cleaning cycle. This dissolves coffee oils and residues that contribute to clogging.
- Repeat the cleaning process as recommended, usually every 1-2 months, to prevent buildup.
Step 4: Manually Clean the Grinder Burrs and Chute
After using cleaning tablets, inspect the burrs and chute. Use a brush or cloth to wipe away any remaining debris or oily residue. For stubborn buildup, a small amount of warm water with a mild detergent can be used, but ensure all parts are completely dry before reassembling.
In my testing, thorough manual cleaning significantly reduces clogging incidents and improves grind consistency.
Step 5: Reassemble and Test
- Once everything is dry and clean, reassemble the bean hopper, water reservoir, and any other removed parts.
- Plug in your machine and run a test grind, observing for smooth operation and absence of unusual noises.
- If issues persist, consider descaling your machine or replacing water filters to prevent mineral buildup that can contribute to clogging.
