- Reassemble the parts securely and run a rinse cycle to see if water flows properly.
Persistent flow issues might indicate a need for descaling or professional servicing.
Cleaning and Descaling Your Machine
Regular cleaning extends the life of your Breville Bambino Plus. Use official Breville BEC250 Espresso Machine Cleaning Tablets for thorough cleaning of coffee oils and residues. To descale your machine:
- Mix the descaling solution as per manufacturer instructions.
- Run the descaling cycle following the machine’s user guide.
- Rinse thoroughly by running clean water cycles afterward.
Descaling should be done every 2-3 months, depending on water hardness and usage frequency.
Replacing Water Filters and Maintaining Water Quality
To keep your espresso tasting fresh and to protect internal components, replace the charcoal water filters regularly. For the Bambino Plus, Breville recommends changing filters every 2 months. Use compatible filters like the Breville Charcoal Filters (asin=B000VX44OO) or the Possiave 12-Pack Charcoal Water Filters (asin=B089R7ZRBG).
To replace:
- Turn off and unplug the machine.
- Remove the water reservoir.
- Lift out the old filter and insert a new one, ensuring it’s seated correctly.
- Refill the reservoir and resume use.
Handling Common Error Messages and Alerts
The Bambino Plus may display error messages such as ‘Water Shortage’ or ‘Temperature Error.’ Refer to the user manual for specific troubleshooting steps for each alert.
Generally, ensure the water reservoir is filled and properly seated. If overheating or temperature issues persist, allow the machine to cool down and check for scale buildup that might impede heat transfer. If errors continue, contact Breville support for professional assistance.
