Thought I would finish off this thread. :D The pilot light died completly although the ignitor was still working. Suspecting a blockage I removed the injector and pipe both were clear. Giving up at this point I called in the professionals. After second visit the ignition lead and sensor was...

I did take your advice but found it very difficult to get in with the probes to measure the voltage across the valve although I did check the resistance with the pcb removed. The term flame rectification was not mentioned only rectification. If I did undersand the system I would not be on...

If the electrode gap wasnt right surely the pilot would not light. it seems to be the next bit thats not working, that is the main burner wont light because the gas valve wont open for whatever reason. Would go ahead and just put in a new ignition board but worried it might not be the cause...

thanks Tony, tried to check the readings earlier but very difficult to get in. Spoke to ravenheat but they were unwilling to discuss fully as I am not corgi registered but said that the gas valve was not getting rectification. I take it by this that one of the diodes is blown. If this is the...

Thanks for help guys. as someone suggested it turned out to be a loose pressure pipe on the pressure switch. Fixed that and the igniter works and pilot now lights. Now the main boiler wont light! acording to the fault finding chart its either the ignition board or the gas valve. It says check...

Thanks Mickeyboy will try them tomorrow.

Have looked at the fault finding chart, it points to condensing trap sensor but that doesnt seem to be problem as there is continuity through it. Just wondered if it might have been a common fault. Dont want to start forking out on parts on trial and error.

The pilot igniter seems to have failed there is no spark even if I disconnect the wire and try jummping it on to earth. Pump and fan are running and I have continuity on igniter wire back to ignition board. Is it likely to be the board or is there anything else I can check first?
