Routine Cleaning and Care
- Ensure the machine is unplugged and cooled down before cleaning.
- Remove the portafilter and rinse it with warm water to clear coffee residues.
- Use Breville BEC250 Cleaning Tablets by placing one in the portafilter and running a cleaning cycle as outlined in the manual. This removes coffee oils and residues, keeping the brew quality high.
- Clean the steam wand with a damp cloth after each use to prevent milk residue buildup.
- Wipe the exterior with a soft, damp cloth regularly to keep it looking new.
For thorough cleaning, descale your Bambino Plus every 2-3 months or as needed, especially if you notice a decline in performance or taste.
Descaling and Mineral Buildup Prevention
Mineral deposits from hard water can impair the heating system and water flow, affecting espresso quality. Regular descaling is essential for maintaining efficiency.
- Fill the water reservoir with a descaling solution or equal parts of water and white vinegar.
- Run the descaling process through the machine following the manufacturer’s instructions.
- Rinse the reservoir thoroughly and run fresh water through the system to remove any descaling residues.
- Repeat every 2-3 months or more frequently if you have hard water.
Using charcoal filters can also reduce mineral buildup and improve water taste, which is crucial for optimal espresso extraction.
Troubleshooting Common Issues
- No water flow: Check if the water reservoir is full and properly seated. Clear any blockages in the water outlet or steam wand.
- Machine not heating: Verify power connection. If the ThermoJet heating system is not activating, reset the machine by unplugging it for 30 seconds, then plugging it back in.
- Uneven espresso extraction: Ensure the coffee dose is correct (19 grams), and the grind size is appropriate. Clean the shower screen and filter basket regularly.
- Leaking water: Inspect the water reservoir and seals for cracks or misalignment. Replace if necessary.
Replacing Charcoal Filters
To ensure pure water and optimal taste, replace the charcoal filters every two months or after 50 uses.
- Turn off and unplug the machine.
- Open the water reservoir lid and lift out the old filter.
- Insert the new filter, ensuring it is securely seated.
- Refill the reservoir with fresh water and run a rinse cycle if recommended.
Regular filter replacement prevents impurities from affecting the flavor of your espresso and prolongs the life of your machine.
