Firstly hello to everyone out there - I hope someone can help me.
As per subject, my boiler has suddenly decided to stop working. The pilot is sparking, but is not lighting. One thing I noted was that the boiler is trying to light (sparking) even though I am not calling for heat ie. CH & HW are both off at the programmer - I don't know if this is normal. I have also tried lighting with heat on demand & no difference noted.
Now I have read up on some similar occurrences on this forum but none exactly matched my scenario.
I have neons 1, 2 & 3 lit but not 4 so some sort of injection/firing problem (so I am reading from the manual). The fan is running when trying to ignite.
I have dismantled & checked the pilot injector for blockage but the 2 very fine holes are present & not blocked.
I have put the flame from a lighter on the pilot electrode & when I get it exactly in the right place I can get the sparking to stop & you can hear what I assume is/are the solenoid/s clicking but neither the pilot nor the main burner light.
To me, it appears that there is no gas to the pilot & possibly the main burner - wouldn't the main injector light when putting a flame at the pilot to achieve flame recognition ie. when the spark stops ? I assume checking the actual gas supply to the boiler is strictly for a qualified professional ?
Thats about as much as I know - other than the boiler must be about 10 years old & has certainly not been serviced for at least the last 6-7 years
Thanks in advance for any help offered & sorry for the long post.
