Morning.
I have a britony combi se boiler. when it tries to start I hear a fan start and that’s about it then after 5-10 seconds the non flame detected light comes on. when I reset it, it happens again. All gas bills are paid so I don’t think its feed. Could it be the ignitor? I don’t know much about boilers and the instructions are pretty useless any help?
Cheers
Ben

Do you have your Installation & Operating Instgructions. Page 12 tells you what's wrong when lights are flashing.

It could be the Air pressure Switch or Venturi, or if the sequence is going further before failing, gas control valve , ignition electrode HT Lead, or PCB

as you will see I have named just about every part on the Boiler.

You should call a Registered Gas Engineer who will carry out an intelligent diagnosis of the fault and change the component that is causing the fault
