Hi,
Noticed i have an intermittent problem with my boiler. It's approx a 1998 model.
Firstly when it lights it struggles to keep lit, with a spark and banging noise. When i watch the pilot it stays lit for a second or two then goes out, due to the bang, (which i assume is the gas valve shutting off), then repeats several times, about 10 times then stays lit. During full burn it randomly cuts out and does the same. Sometimes it lights fine.
I'm not sure how long it's been like it because it's in the garage.
I've watched the tell tail pcb lights, when this happens number 4 'pilot pcb proven' goes out.
Can anyone point me in the right direction? Wondering if it's a lack of Gas flow which then cuts it off, a dirty injector/nozzle etc or a pcb fault?
Thanks.
