No I arnt gas safe, and the pcb board was a reconditioned one from a friend, and the little screen doesn't work, well I have ordered a element detection probe so will swap that over to see if it makes any difference!
I am a plumber with experience just never done much with boilers but I know the basics
Boiler is igniting then lighting, but just not staying lit, also it does not display error codes as we had the pcb board changed 2 years ago.
Any help will be greatly appreciated!
Thanks Frazer
