hi there. our boiler keeps going to lockout with an 01 fault. Our plumber has tested the ignition and says its ok. Thought may be electrical and changed main pcb (££££) and also replaced both NTC sensors. The boiler will stay on, from cold, for about an hour, then locksout. Any ideas??
Ps i'm new, posted this already, but not sure if I did it correctly first time. Sorry if you have read already.
Many thanks, Melanie
