Should I have power at both elements all the time?


Push circuit breaker fully off and then fully ON
Test for 240 volt across top twp screws on upper thermostat.
If tank was not full of water when breaker was turned on, then upper element burned out.

Yes both elements will test for 120 volt to ground at all times... but it takes 240 volt to heat element

Brand new water heater not working


touch your volt meter to the element wires with power on to see if you get 240 that far. if you do your element is bad. they can test good and still be bad. if you dont get 240 to it then you have a bad reset switch

Not getting 240 volts to lower element- have replaced lower element and both thermostats. get 120 on each leg to ground but no 240


If your top element is bad the the lower element will never turn on be cause the top element completes the 240 circuit. It is like a resister in a circuit. Make sure top element measures out at 13 ohms.

Have sta kleen 805 , have power,240 v no hot water


If I understand correctly, your water heater circuit tested for 240 Volts.

1) If circuit has power on one leg of the 240V circuit, water heater can appear to have electricity, but won't turn on since 240V needs both legs to complete the 240V circuit. Solution: test for 240 across top two screws on upper thermostat.

2) ECO reset button tripped on upper thermostat. Solution, push in reset button. If reset will not reset, then replace upper thermostat. I usually replace both upper and lower thermostats at same time: cost $28. Buy parts from home center or hardware store. Be sure to put factory-insulation and covers back so thermostat is not exposed to cooler outside temperatures, that cause hotter water than set point.

3) If ECO reset button keeps tripping, then keep resetting until you can test water heater parts. Spend 30 minutes and do complete troubleshoot on tank.
Buy cheap multi-meter from home center. When test calls for checking voltage, rotate dial to 240-250-277 VAC. When test calls for checking continuity or elements, rotate dial to Ohms (upside down horseshoe is ohms).

The controls of electric water heaters are designed so that at no time are both the top and bottom heating elements energized. Nearly all electric water heaters of this capacity in the US & Canada (other places, too) operate on 240 Volts.

When the water in the tank is below the set point of the thermostat (in your case - 120 degrees), the top heating element is expected to be on - (unless there is an issue with the top thermostat or limit switch). The top most control is the "high temperature limit". It is identified by the reset button on it. Make sure this isn't tripped by depressing the button. If it clicks - it was tripped and should start to make hot water at this point. If not tripped, you should check for the presence of 240 Volts between the heating element terminal screws. Do not measure from ground to a terminal screw and believe 120 Volts is "good". To make heat, you need 240 Volts - not 120 Volts measured across the terminals - not to ground. The amount of heat created running at 120 Volts is only 1/4 of what it will do at the correct voltage.

If you don't measure 240 Volts on the top element, check the bottom element in the same manner described for the top element.

If unable to measure 240 volts on any element, either there is a problem with the power source (blown fuse or circuit breaker), high temp limit switch, or thermostat(s).

If 240 Volts is present on either heating element, and water is not warm / hot in 30 minutes or so, a defective heating element is suspect. You can change controls without draining a tank, but replacing elements will require draining the tank first. Do not power the water heater without first filling it.

You can read a very detailed "how to" article about checking water heaters here.

I hope this helps - and good luck!

Purchased "Reliance Lowboy electric water heater"


The water heater has two 4500 watt elements.
However both elements are not turned-ON at same time
So the water heater is 4500 Watts

Volts x Amps = watts
Amps =watts divided by volts
Amps = 4500 Watts divided by 240 Volts
Amps= 18.75

So that says a 20 amp breaker ... except for the 80% rule
80% rules says for safety, your Amp rating should be multiplied by 80%

20 amp breaker X 80% = 16 amps
20 amp breaker is actually safe for just 16 amps, and your water heater draws 18.75 amps.

The calculation shows you need a 30 Amp breaker.
30 Amp breaker requires 10 gauge wire.

Water heater electric


if its a 240 volt unit,then yes they are both 120 volts for each phase and the 240 volts for combined pair to each terminal on the units thermostats terminals,hope you have a white or green or both for a safety ground though just in case there;s plastic water lines between the supply and the unit

Not heating


un hook the incoming power lines, turn the breaker back on, and carefully measure power between the 2 hot wires, not the ground. You must have 220 to 240 volts between these 2 wires, if you dont either the breaker is bad, or the wire is broken somewhere. If you have 240 volts to the heater, with the power OFF unhook the wires from both elements and use an ohm meter to test the resistance on the elements, both should be around 30 ohms and about the same, if not one is bad. Test across the elements after re connecting them and turning the power on you must have 240 volts across the elements when they are on, if you have only 120 or 0 then the trouble is the breaker or the wire.

No hot water


If the water does not heat, then you have to troubleshoot to find the problem. With a voltmeter determine if 240VAC is actually getting to the water heater. Take care here - a defective circuit breaker can give a false 240 volt reading - check for the 240 volts across the upper element (i.e. when the 240 volts has a live load on it, not just an open circuit test).
Also, remember, the upper element has priority over the lower element, and if the water is cold, the upper element will try to turn on and this locks out the lower element (only one element is allowed to heat at any given time). The lower element comes on ONLY after the upper thermostat is satisfied. Therefore if the upper heating element is burned out you will never get any hot water. If you suspect this, TURN OFF THE POWER TO THE HEATER and take a resistance check of the upper element.
