If it is generating pressure, then that eliminates the vacuum relief valve, as that would never let the machine generate pressure to begin with.
I’d say the next step would be to see at what pressure the steam starts to leak, and see if you can identify from where. Since the pressure relief operates somewhat violently I’d recommend removing the top and sides to expose the boilers, and placing the machine somewhere safe like outside. Then I would turn on the steam boiler (while being cautious of live wires) and watch the gauge. Be sure to keep away from the relief valve while testing. If the pressure gets up to 1.5-2 bar and the pressure relief suddenly goes off then it is most likely to be the pressure stat needs to be adjusted or replaced. May as well try adjusting it first since replacing them is known to often be a trickier task then expected. It would also be worth disconnecting the pressurestat and verifying that there are no shorts in the wiring with a multimeter. If the pressure does not get up to 1.5-2 bar before the pressure relief valve goes off, then the relief valve has failed and should be replaced (unless it is the style that can be adjusted but most are not). If steam leaks the whole time identify where it is leaking from and make sure connections are snug. It’s possible something has corroded or gotten loose in the past 8 years and is the cause of the issue.
