Follow these instructions carefully to restore your machine’s pressure and enjoy café-quality espresso at home.

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.
