Another possible reason is that the portafilter itself is not seated correctly. This can cause the water to spray out as well. Make sure that the portafilter is firmly seated in the espresso machines before you begin brewing.

Finally, it’s possible that the espresso machine is not set up correctly. If the water pressure is too high, it can cause the water to spray out of the portafilter. Check the settings on your espresso machine and make sure that the water pressure is set correctly.
