Check the Coffee Grind and Dose
- Ensure you are using the correct grind size — it should be fine but not powdery, similar to table salt.
- Use the recommended dose of coffee — typically 19 grams for the Bambino Plus — and evenly distribute it in the portafilter.
- Make sure the coffee is tamped firmly and evenly to ensure proper resistance and pressure build-up.

Inspect for Blockages and Clean the Group Head
- Turn off and unplug the machine before cleaning.
- Remove the portafilter and run hot water through the group head to clear any residual coffee grounds or blockages.
- Check the shower screen for clogs; clean it gently with a soft brush or cloth.
Descale and Clean the Machine
Build-up of mineral deposits can affect pressure. Use a descaling solution or Breville’s cleaning tablets to descale your machine regularly, following the manufacturer’s instructions.
For daily maintenance, run water through the system without coffee to flush residues.
Check the Water Filter and Water Quality
If your machine has a water filter, ensure it is not clogged. Replace charcoal filters or water filters as recommended—every 2 months or as needed.
Use good-quality, filtered water to prevent scale and impurities that can block water flow and pressure.
Test and Reset the Pressure System
- Power off the machine, then turn it back on to reset internal systems.
- If pressure issues persist, consult the user manual for specific reset procedures or contact support.
