Hi, im having the same problem. the boiler lights and then extinguishes after a couple of seconds, does it three times and then the boiler lockout red light comes on. Heating isnt on, so its just when hot water.

Pressure was at 1 bar and we thought it might be low pressure, as it previously has dropped to less than one but fixed this, one of the valves was open so dad closed it. Increased pressure, now at 2bar and seems to be ok but is this too high? We are stumped now, please help
