Key Takeaways
| Check for blockages | Clogged filters or shower screens can cause pressure issues. |
| Clean regularly | Using proper cleaning tablets prevents oil and residue buildup. |
| Inspect water filters | Impurities or clogged filters reduce water flow and pressure. |
| Descale your machine | Mineral deposits can block water pathways and affect pressure. |
| Ensure correct grind size | Too fine or coarse grind affects pressure during extraction. |
Step 1: Power Off and Unplug
Always turn off and unplug your Breville Bambino Plus before performing any maintenance or troubleshooting to ensure safety.
Step 2: Check and Clean the Shower Screen and Filter Basket
- Remove the portafilter and detach the filter basket.
- Inspect the shower screen for coffee oil or debris buildup.
- Clean the shower screen and filter basket with a damp cloth or soft brush.
- Reassemble and run a blank shot to see if pressure improves.
Step 3: Descale the Machine
Mineral buildup can restrict water flow. Use a descaling solution or the recommended cleaning tablets to descale your machine following the manufacturer’s instructions. Regular descaling maintains water pressure and machine performance.
Step 4: Check and Replace Water Filters
Impurities in the water filter can impede water flow. Remove the existing filter and replace it with a new one, such as the Breville Charcoal Filter or the Possiave Water Filter, ensuring proper fit and placement.
Step 5: Adjust Grind Size and Dose
Ensure your coffee grind isn’t too fine, which can cause high resistance and no pressure. Use a burr grinder to achieve a medium-fine consistency, and measure 19 grams for full flavor extraction.
