If your Breville Bambino Plus is not building pressure during extraction, it can lead to weak or under-extracted espresso. This issue often stems from blockages, worn parts, or improper maintenance. In this guide, you’ll find clear, safe steps to diagnose and fix the problem effectively.
Follow these instructions carefully to restore your machine’s pressure and enjoy café-quality espresso at home.
Key Takeaways
| Check for blockages | Clogged filters or shower screens can cause no pressure. |
| Clean regularly | Oily residues and mineral buildup impair pressure. |
| Inspect the portafilter and basket | Worn or damaged components can affect pressure. |
| Ensure proper grind size | Too coarse grind results in low pressure during extraction. |

1. Turn Off and Unplug the Machine
For safety, always turn off and unplug your Breville Bambino Plus before starting any troubleshooting or maintenance.
2. Check and Clean the Shower Screen and Filter Basket
- Remove the portafilter from the machine.
- Take out the filter basket and inspect it for coffee grounds or clogs.
- Soak the shower screen and filter basket in hot water or use a cleaning tablet (see recommended products).
- Use a soft brush to gently scrub away any residue.
3. Descale and Clean the Machine Internally
Mineral buildup can restrict water flow and pressure. Use a descaling solution or cleaning tablets suited for Breville machines, following manufacturer instructions. Regular cleaning extends your machine’s lifespan and ensures proper pressure.
4. Check the Portafilter and Grind Size
- Ensure you’re using the correct grind size—finer grind increases pressure.
- Inspect the portafilter for damage or worn components.
- Re-dose and tamp the coffee evenly.
5. Test and Adjust
Reassemble the machine, run a test shot, and observe the pressure gauge. If pressure remains low, repeat cleaning steps or consider replacing worn parts like the portafilter gasket.
