Step 2: Check for Blockages in the Portafilter and Group Head
- Remove the portafilter and inspect the filter basket and shower screen for coffee grounds or debris.
- Clean these parts thoroughly with a brush and warm water.
- Ensure the portafilter is seated properly when reattaching.
Step 3: Descale the Machine
Mineral buildup can impede water flow and pressure. Use a descaling solution or the recommended cleaning tablets, such as the Breville BEC250 or the Replacement Espresso Cleaning Tablets.
- Follow the manufacturer’s instructions for descaling your Bambino Plus.
- Run the descaling cycle to remove scale deposits.
Step 4: Replace or Clean Water Filters
If your machine uses charcoal filters, check if they are clogged. Replace with new filters like the Breville Charcoal Filters or the Possiave Water Filters.
- Remove the old filter from the water reservoir.
- Insert a new filter and ensure it’s securely in place.
Step 5: Verify and Adjust Grind and Dose
A grind that’s too fine or too much coffee can cause excessive backpressure, leading to no pressure during extraction. Use a consistent dose with the 54mm porta-filter and aim for a balanced grind size.
- Adjust grind size if necessary, making it slightly coarser.
- Use 19 grams of coffee for optimal extraction.
