Pilot light won't stay lit.
Got home from work (11:30pm) to find that I have no hot water. So I pop the two doors off the water heater to find that the pilot light is out. So I follow the steps to relight it. It stays lit until I turn the dial to warm then goes out. Relit it three times and the same thing each time. IT will stay lit but as soon as I turn the Dial half way to HOT the flames from the burner come out past the pilot light up the side of the water heater, with the inner door in place, then goes out. Any ideas?
