Adjust Grind Size and Tamping Technique
- Use a consistent grind size—slightly finer if pressure is too low, coarser if too high.
- Tamp the coffee evenly with firm, consistent pressure (about 30 lbs of force).
- Ensure the coffee bed is level before brewing.
Check Water Reservoir and Filters
- Make sure the water reservoir is filled and properly seated.
- Inspect the water filter (if installed) and replace it if clogged or expired.
- Clean or replace the charcoal filters regularly to prevent impurities from affecting pressure.
Descale and Remove Mineral Buildup
If you notice a decrease in pressure over time, mineral buildup may be the cause. Use descaling tablets or a descaling solution following the manufacturer instructions. Regular descaling prolongs machine life and maintains optimal pressure.
Perform Routine Maintenance and Troubleshooting
- Clean all removable parts regularly.
- Ensure the machine heats up fully before use.
- If issues persist, consult the user manual or contact Breville support.
