A common problem with electric water heater installation is turning the power on before the tank is completely full of water. After the plumbing connections are complete, but before connecting electric power, open a hot water faucet all the way until the “hot” water runs FULL STREAM for three minutes. When first opened, you may only get air out of the faucet, then spurts of water. Wait until the water runs full and let the water run full for three minutes. If the tank is not completely full when power is turned on, the upper heating element will burn out and you’ll have no hot water (until the upper element is replaced). Note – You will also need a circuit tester or volt meter to check for electric power.
