Water heater still won't heat after replacing thermostat and elements
With your volt meter check the voltage at both terminal screws at the same time (screw to screw ) the voltage should be about 230 volts. If it is not 230 volts then you probably have one leg of the 230 volt line open or not energized. Try shutting off the circuit breaker for the water heater and turning back on. If no change you may have a bad circuit breaker or broken wire.
