Hello All,
I have have a gas halstead combi boiler 30/90.
My water pressure went down to 0.3 bar and my boiler stopped working. I got the water pressure back to 1.5bar, but now it will not ignite or even spark. It is not the air fan switch. Could this be the thermocouple or a overheat stat switch? If so how can I check this or is there anything else it could be?
Thanking you all in advance,
Malcolm
