Most likely it will be a duff PCB. But check your polarity, earth continuity and see if the gas valve is opening and closing.

Listed below is from the manual.

F.61

Gas–valve control defective

Short circuit/earth (ground) leak in cable harness to gas valves, gas valve assembly defective (earth/ground leak from coils), electronic control system defective.

It’s very likely that’s the pcb it has something to do with the low voltage. If it’s intermittent then I would take a cup of tea and watch if temperature jumps quite rapidly. If that’s the case stick a new pcb in.
