Viessmann vitodens 200 wb2 11-44 boiler problems

in THE MAIN WALL

hello all I am having a problem where the boiler starts ,lights up,and shuts down right away

This will happen a few times and then it will light

There are no codes but viessmann manual says this symptom is due to flue gas system leaking

I have cleaned out in between radial heat exchanger with tool and flushed thoroughly with water

There is not a glue gas smell

Any help would be appreciated

Thanks

Brett

    follow up on my viessmann

    Turned out to be the gas valve

    Fortunately I bought a complete used boiler for $550 and had the spare part

    Thanks for the help
