    What was the flame current just before it shut down. Was the O2 verified ?

    These are the original symptoms before the re-assembly and after with the new parts. Also this runs occasionally for days without fault for DHW requests.

    I measured volts and amps at the gas valve during this diagnosis. The amps I did not show in this video. I can check the micro amps and try to see if I can catch it faulting.

    How do I verify the O2?

    That tool costs to much for me art this time.

    After doing the 8000 hours service nothing had changed but it was needed and glad I did it. The only thing left that I narrowed down the issue to was the gas valve. As I showed in the video you can see it open and close multiple times upon a request. When I replaced the valve I noticed that the O-ring on the old one was in very bad shape. This could have been the source of failure causing extra air to enter into the combustion process, not sure. With the new gas valve installed and over a month of data everything is working fine.

    Thanks everyone for your assistance.
