Watch the ignighter while your wife throws the switch. Are you getting spark? I'm not sure, maybe there is a reset if the tank gets too hot.
it has what seemed like two reset buttons ,it didn't work.what ignites he gas and how does it know when to ignite?
The gas is ignited by a spark generated by the control board when the thermostat says the water is cool. The control first opens the electric gas valve then generates the spark. It then monitors the flame (via thermocouple) to insure it has lit. If it has not, it will shut off the gas valve.
