  • Electric Water Heater

    Had a electric water heater that was installed in 1987 and just stoped working. In an attemp to save money I replaced bothe elements. Still no hot or even luke warm water. Tested for power and got 120 volt on both legs at the main connection at the water heater. and at the elements. So I figured the thermostats were bad, went to M and bought a new heater, installed it, open the hot water faucets in the house and turned the water on to the heater until I had a steady stream of water ot the faucets with no air. Flipped the breaker, and waited and waited and I am still waiting for hot water 3 hours later. I am getting 120 on each leg of the supply but is possable the breaker went bad and I am not receiving the wattage?

    Re: Electric Water Heater

    Where and how are you checking for voltage?

    From one leg to ground or across both legs?

    Check it at the top element

    Can you check for amperage with your meter?

    Double check your wire connections

      Re: Electric Water Heater

      Wire connections are tight, twisted and covered with wire nuts
      Checking the voltage from each leg to ground at the connection from feed to heater
      Checed bottom element from each terminal to ground
      I cannot check amperage with my tester

        Check it at the top element. That's the one that's going to be energized first.

        It is a 240 volt heater right?

          Yes it is 240 volt
          if I have power at the top element then what do I do?

            Press your ear against the tank near the top element. You should hear a slight humm.

                The bid question is do you have 240v when testing both terminals?

                  When you check for voltage at each leg, was the feed wire disconnected from the heater?

                  If it is still connected while checking for voltage you may get an improper reading.

                  It's possible only one of the legs has 120v while the the other one is dead, and if you do a voltage check while the wires are still twisted with the heater wires, the live wire voltage would backfeed thru the element/thermostat and simulate 120v at the dead wire.

                  This happened to me before.

                    You need to measure Voltage between both hot wires. There should be close to 240 Volts. Try to do this at the heater. Shut off breaker, connect meter and then turn breaker back on. Measuring from ground to each hot doesn't tell if there's 240 Volts across the elements. Also measure Voltage across the terminals of both the upper and lower element. Use care not to short anything or you'll get a very nasty arc flash. Also be careful not to zap yourself. If you have a face shield, wear it. If not wear goggles or safety glasses.

                    Just in case somehow there's only 120 Volts at the element and they are rated for 240 Volts the element will just get warm. If you let it go overnight you would have a little warm water in the morning but would run out soon. You must have the Voltage the element(s) are rated at being supplied to the elements. With a cold tank the upper element is energized first. When the top of the tank is hot it shuts off and the lower one is powered.

                    If you can't get anywhere or don't understand this, please call an electrician to help. There may be improper wiring issues or the breaker may be bad.

                        No I tested the feed with them connected to the heater, when I tested accross the two feed I did not get any reading from the volt tester. Any good way to test a breaker, the breaker by the way is one that has only one reset knob.
                        Thanks everyone for all the help.

                          At this point you need to call an electrion.

                            I agree, sounds like one leg is down.
