Step 2: Check and Clean the Portafilter and Basket
- Remove the portafilter from the group head.
- Discard any used coffee grounds and rinse the basket thoroughly.
- Ensure the basket isn’t clogged or obstructed.
- Reattach the portafilter securely.
This helps prevent blockages that can cause low or no pressure during extraction.
Step 3: Descale the Machine
- Fill the water reservoir with a mixture of water and Breville cleaning tablets (or use a descaling solution).
- Run a descale cycle following your machine’s manual instructions.
- Rinse thoroughly by running clean water through the system.
Descaling removes mineral buildup that can restrict water flow and pressure.
Step 4: Check the Water Filter and Reservoir
Remove the water filter (if installed) and inspect it for clogs or impurities. Replace with a new Breville Charcoal Filter or compatible filter if necessary. Also, ensure the water reservoir is clean and properly seated.
Step 5: Inspect the Pump and Valves
Listen for the pump’s operation during a shot. If you hear no sound or irregular noises, the pump might be faulty. Check for any stuck or damaged valves that could block water flow. If unsure, consult a technician for further diagnosis.
