I recently had a pipe break that submerged my boiler under 3ft water. I was able to quickly remove water and dry most components. I replaced the two stage gas valve with a new one. Boiler fires up , runs for a minute or two then (I think when attempting to high fire ?) Trips the new GFCI..

    If the boiler was submerged by all rights you need to replace the whole thing.

    Not quite strong enough, there, @kcopp - at least in these parts if a fuel burning appliance has gone under water, it must be replaced. No ifs, ands, or buts.

    Big brother mandates replacement of that boiler.

    DONT ATTEMPT TO USE OR REPAIR IT!

    Your insurance should cover it.

    Sorry to say but it has to go.

    No safety control can be trusted once water hits it
