We are remodeling the back few rooms of our house and I had to remove the water heater for the tile guys. Today I reinstalled it. I hooked up the two copper flex lines and hooked up the blow-off pipe. I then hooked the white house wire to red heater wire and black to black. I then turned the sink to hot water and let all the air out of the lines. I left for a few hours and when I got back, the water was barely warm. An hour or two later and it was even colder. I turned on the breaker before I bled the lines but surely I didn't burn up the elements in the 3-5 minutes it took to bleed of the air in the system? Anyway, seems like it heated for a tiny bit then failed. The main breaker is on and the subpanel breakers are not tripped. Odd: when I was unscrewing the little screws on the electrical cover plate, it was kind of dark and I could see tiny little sparks when the screw wiggled but it did not shock me to touch it. The top reset button was not tripped, I didn't check the bottom due to tight quarters. I do not have a voltmeter handy at the moment. Any ideas?
