Inspect and Clean the Filter and Shower Screen
- Remove the portafilter and check for coffee grounds or blockages in the filter basket.
- Remove the shower screen and clean it thoroughly with a soft brush and warm water to remove coffee oils and residues.
- Reassemble and run a blank shot (without coffee) to flush out the system.
Descale the Machine
If you notice scale buildup or mineral deposits, descale your machine following the manufacturer’s instructions. Using appropriate descaling tablets or solutions can help restore pressure and improve performance.
Adjust Grind Size and Dose
- Use a slightly coarser grind if your coffee is too dense or slow to extract.
- Ensure you’re dosing around 19 grams in the 54mm portafilter for optimal pressure and flavor.
- Distribute and tamp the coffee evenly to avoid channeling and pressure loss.
Test and Monitor Performance
Run a test shot after completing cleaning and adjustments. Observe the pressure gauge and extraction time. Consistent pressure indicates proper functioning.
If issues persist, consider professional servicing or replacing worn components.
