I just installed a new electric water heater with dual high limit elements.I hooked up the red and black wire, just like the old one and set the limits to 125 and turned on breaker. we waited about 6hrs and did not have any hot water. How long does it take for the water to heat up. I checked voltage at both elements and had 240 on the top one, phase to phase, blue and yellow wire. The bottom one had a blue and yellow wire and I got O volts pahse to phase, but 120 phase to ground which tells me they were the same phase. That is not right , is it

Most water heaters heat the water on top first. This is because the warm water will rise to the top and the hot water is drawn off the top. When the upper thermostat turns the top element off then the bottom one comes on. It makes it sound like there is a problem with the top element. Disconnect electric, and read the resistance on the element terminal to terminal. If it shows open the you have a bad element. Did you make sure the heater was completely full before turning the electric? You must run the hot faucets to remove all the air from the top of the tank before turning on the electric. Elements will burn out quickly if out of the water.
