Step 2: Clean and Inspect the Portafilter and Brew Head
- Remove the portafilter and detach the filter basket.
- Use a soft brush or cloth to remove coffee oils or residues.
- Check for any blockages in the brew head or shower screen; clean with a damp cloth.
Step 3: Descale the Machine
If you notice scaling or mineral buildup, descale your machine following the manufacturer’s instructions. Use approved descaling tablets or solutions.
Step 4: Check the Coffee Grind and Dose
- Ensure you’re using the right grind size — not too fine, which can cause overpressure, or too coarse, which can cause low pressure.
- Use approximately 19 grams of coffee in the 54mm portafilter for optimal extraction.
Additional Tips and Warnings
- Always turn off and unplug the machine before cleaning or inspecting internal parts.
- Use only recommended cleaning products to avoid damaging internal components.
