Reasons why espresso flows over the edge of the portafilter
- Portafilter is not inserted in the group head properly. Make sure the portafilter is completely inserted and rotated until the handle is aligned to the lock icon.
- There are coffee grounds around the rim of the filter basket. Swipe any excess coffee to ensure a proper seal in the group head.
- Too much coffee in the filter basket. Use a lower dose of coffee.
