I have Ravenheat CSI Primary boiler which the pilot light failed to light, there was a clunk of the gas valve and the ignition system would spark but there was no flame. Traced the problem to a blocked jet on the pilot light...thanks to this forum.
Now the next problem is that the main burner does come on. The ignition system sparks, the pilot light comes on but you can hear the ignition system continuing to spark but no life on the main burner. Any ideas? The fault finding flow diagram in the handbook suggests that it is the gas valve but welcome some views before I spend £200+ on a new valve.
The resistance measured on both solenoids of the gas valve is the same....I have had a gas valve failure before.
