Cuprajake Hi Cuprajake, not related with software as is working fine with the steam boiler cold. With steam boiler hot, even if you switch it off, the problem is the same. I serviced my machine, descaled it, took boilers apart, changed the whole piece… still happens. There is pressure comming from the service boiler getting into the brew circuit.
My machine does exactly the same but it gets stuck at the 2 bar mark. In the kautivo’s vesuvius it gets stuck at the 2,5 but his manometer shows 0,5 when iddle so… exactly the same “barrier”
