    I presume you have done the basics and also checked the combustion readings after replacing electrodes?

    We deal with boiler faults every day.

    There can be several causes of ignition lockout.

    But we don't give DIY advice on gas/combustion issues.

    All you can do is check the condensate drain is free flowing and if so then call a competent engineer.

    I have tested and checked everything on the boiler that could have anything to do with ignition lockout even worcester tech could not think of anything I have not done
    Gas supply pressure is 20Mbar working
    CO levels are spot on
    I'm getting -9Mbar at the fan test point so no blockage

    I think it may be the control board but worcester say not

    Just as well we did not give you DIY gas advice when you are hell bent on fixing it yourself.

    Have Worcester seen you boiler to tell you that its not the PCB?

    Have you tried an FGA?

    So what are you going to do now?

    Hi Tony

    No worcester have not seen the boiler

    I don't want DIY advice I would just like to know if anyone has had anything like this before and if so what was the problem.

    Anything you can suggest would be good

    How can you test the CO2 levels without a FLUE GAS ANALYSER?

    May be I'm posting on the wrong site, but I have seen the answers given on this site and thought I would give it a go.

    Thanks

    You will not get any advice here you are obviously incompetant and changing electrodes without checking with a FGA is ridiculous.

    But you ARE asking for DIY advice!

    You are a DIYer and asking for information on faults.

    Worse you are clearly prepared to do which well beyond the capabilities of a DIYer!

    If anyone did give you advice it would be deleted as the rules don't allow it.

    I expect that I have seen most boiler faults. But how could that help you?

    Call an RGI !
