The hot water heater lights the first time it is turned on but one it goes out will not relight. I do here a humming noise from the control box. I guess bthat could be my issue. Any other suggestions?Re: Hot water heaterI did not think to even check how hot the water was getting when it heat up. once i could tell it was getting hot i turned it off.Hot water heaterI went camping last weekend and had an issue with hot water heater. It fired up fine when i first turned it on, but after a few hours the DIS light would be on. If i turned it off and on again, it would heat up again, but would never kick back on. Any ideas on what would cause this . Thermostat Sensors maybe. ❚ Did you see the "Announcement : ★★READ BEFORE POSTING HERE★★" at the top?
