Check the Water Level and Flow
- Ensure the water reservoir is filled to the recommended level and properly seated in the machine.
- Inspect for any kinks or blockages in the water intake tube.
- Run a brief water cycle without coffee to verify water flow is unobstructed.
Clean the Shower Screen and Filter Basket
- Remove the portafilter and detach the filter basket.
- Clean the shower screen with a soft brush or cloth to remove coffee oil buildup.
- Soak the filter basket in hot water or use cleaning tablets periodically.
Check and Adjust Grind Size and Tamping
- Use a medium-fine grind suitable for espresso—too coarse reduces pressure.
- Distribute the coffee evenly in the portafilter and tamp with firm, consistent pressure.
- Avoid over-tamping, which can block water flow.
Perform Regular Maintenance and Descaling
- Use recommended cleaning tablets to clean the machine’s internal components.
- Follow descaling procedures regularly, especially if using hard water.
- Replace charcoal water filters every 2 months for optimal water quality.
Troubleshoot Common Mechanical Issues
If pressure problems persist, check for worn seals or gaskets and replace if necessary. Consult a professional technician if internal parts appear damaged or if the machine still shows pressure errors after cleaning and adjustments.
