Help... water heater won't light

Nice call Charlie!

If the WH shuts down after 10 minutes, does not try to reignite, but fires up an hour later it sounds like all is working fine. I'm wondering if the WH is really heating properly and satisfying the thermostat but the WH bypass valves are set improperly giving you the impression the water is not hot. If you're plugged into 30A the electric side of the WH should work fine and you should get HOT water.

Indeed. Actual troubleshooting based on the symptoms, isolating the point of failure, devising a test to narrow it down. Textbook. (as opposed to the usual "guess-change-guess-change" cycle)

Bingo! Forgot to close the middle bypass valve so cold was mixing with the hot, thermostat keeps it from lighting and the random light isn't when the tank drops below temp. Thanks! I can take a shower now!

Glad you found the problem. I was running out of ideas. When something stops working I always ask two questions: What changed and could it be a short between the headphones? Camp on!

Thanks me too! This problem was a combination of both... Something changed and user error. Or in my profession we have the picnic error... Problem In Chair Not In Computer.
