Hi gents, i've recently encountered a problem with my combi boiler and was wondering if any of you kind gentlemen would be able to point me in the right direction. The problem appears to be that when i engage either the c/h or the h/w the burner initially comes in but then after several seconds cuts out, then back in again and then out again and so on resulting in neither the h/w or the c/h reaching the required temperature, any ideas please.
