That explains why you don't have a red warning - between 100 and 150 bar you get a white/blue warning, and below 100 it goes red (system shutdown). But 138 indicates the pump is indeed primed. So it points towards a leaky valve block or leaks somewhere else. I do hope pressurizing the tank fixes it. Keep us posted!

Thanks for pointing out the pressure it makes me retrace my steps.

I will figure out tomorrow how to pressurize the tank. Think I might just set my air compressor to one bar and use a fitting to connect to the tank. Or I will come up with something else
Thanks once again
