Hopefully your supplier used a portafilter pressure gauge and set the OPV to 9 bar at the group. This is a component of our bench test .
The pressure gauge on your machine is a system pressure gauge and will typically read up to 1.0-1.5 bar higher than group pressure (with a blind filter in place).
If it wasnt set, you might ask your supplier to do the job so that you have an accurate indication. ;)
