Am I correct that during extraction I should getting around 9 Bars (currently geting 3.5 bars)
Is there an easy way to check the opv pressure?

Is the opv on this machine set up like a bypass? It may be your pump - have you tried measuring the raw pump pressure?

Put in a blind if the machine comes with one OR choke it with a fine grind and heavy tamp and see what the gauge reads...

With no flow it should give you an indication on the gauge as to what it thinks it is.

Gauges are not always super accurate but if it comes in at around 10 +/- 1 bar ya OPV is more than likely doing what it is required to do..

If ya shots still at 3 or 4, then it is a good chance that is you and your beans/dose method etc...
