Wattage is printed on end of each element.
If water heater has 2 elements, then it is 240volts
Only 1 element is ON at a time. Both elements are not ON at same time.
Example element is 4500 watts
So when water is ON, it is consuming 4500 watts
When water heater runs for 1 hour, it has consumed 4500 watt hours.
1000 watt hours = 1 kilowatt hour
So water heater running for 1 hour consumes 4.5 Kilowatt hours
http://waterheatertimer.org/How-to-install-electric-meter-on-240Volt-water-heater.html

How many hours per day does water heater run?
It depends on thermostat temperature, temperature of incoming cold water, amount of hot water consumed, if hot water is dripping at faucets, etc.
Modest-consuming 2 person household will consume 7.6 Kilowatt hours per day. Or 228.75 Kilowatt hours per month x $.14 per Kilowatt hour = $32 per month.
4 person household can consume twice as much hot water.

Most electric water heaters have 2 heaters - an upper and a lower, each with it's own thermostat. These are readily accessible by removing the screw covers on the side of the tank. Careful - the thermostats have 240VAC on the terminal screws (unless you have a small 120VAC heater) if the circuit breaker or fuses feeding the heater are still on - turn them off before proceeding. After removing the two screw covers and pulling back the insulation you will see temperature (screw) adjustments for the upper and lower thermostats, with a temperature indicating pointer attached to each screw. Set both thermostats to 125 degrees or so. Push the insulation back in place, replace the covers and turn the circuit breaker back on that feeds the water heater. You should have warm water within 15 minutes and hot water within a hour or so.

If the water still 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. 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.

How do I turn up the water temperature on a Marathon 85 gallon electric water heater? I don't see any visible temperature control settings.


The temperature is controlled on the thermostats in the tank. They are under the two covers you see on the outside of the tank. There is an upper and lower thermostat. Make sure you shut off the power before you begin. Remove the cover and peel back the insulation covering the thermostat. Use a flat head screwdriver to adjust temp. There should be a pointer showing the temp its on now. They are probably set at 120 degrees. WARNING--turning your hot water temp above this point can cause scalding and burning in less than 3 seconds. You may have a burnt out lower element. This link below should help you

This is the manual to your tank. Good luck.

The only Whirlpool electric heater I know with control board is Energy Smart electric:
Open following link to identify product and download sample manual:
http://waterheatertimer.org/Whirlpool-Energy-Smart-electric.html

First of all, the water heater is always full of water.
When you turn on hot water tap, hot leaves top of tank, and new cold water immediately enters bottom of tank through the dip tube. The tank never has air pockets as these would damage tank as explosive steam would fill that pocket ... remember they used to run locomotives with steam power.
So the tank is always full of water, and you know that since no air comes out of the hot water faucet.
http://waterheatertimer.org/How-it-works.html

You did not say if this is new heater, or if heater was working correctly and stopped functioning.

What you describe does not sound normal.
I suggest calling Whirlpool at 1-877-817-6750.
You need to have serial number and model number from label on side of tank so product can be fully identified by Whirlpool.

If control board is bad, they will know and will sell you new board.
Installation is easy, and wires are color coded.
Replacement comes with instructions.

The evidence points to a control malfunction.
Call Whirlpool for assistance: 1-877-817-6750
You will need your model number and serial number located on label on side of tank.
Serial number is required because models change as the technology evolves.

Open following link to read product details about the Energy Smart, and download typical manual.
http://waterheatertimer.org/Whirlpool-Energy-Smart-electric.html

Note: Energy Smart water heater requires 10 gauge wire and 30 amp breaker.

Typical energy smart manual shows: 1 flash is start-up error, which indicates 'Power ON with no water in tank.'
This is not possible because at least the upper element would burn out, if not both elements.
If upper element burns out, this water heater will not make any hot water, since it is wired for ordinary non-simultaneous operation.
There cannot be air inside the tank since your hot water faucet is not spewing air.
http://waterheatertimer.org/How-it-works.html

Also be aware that model numbers change.
Read following account of fellow who replaced control board on his 4-year-old energy smart, and how he discovered wires are reversed on newer control boards. Be sure to ask Whirlpool about this possibility, in the event they say control board is faulty and send you new board:

2 green flashes. hot water is blazing hot set at 120 degrees.have the energy smart unit model#ee2h50rd045v . what is wrong?


2 green flashes is 'High Water Temp.'
http://waterheatertimer.org/Whirlpool-Energy-Smart-electric.html

Typical energy smart manual:
http://waterheatertimer.org/pdf/Whirlpool-energy-smart-electric-manual.pdf

3 flashes is Temperature Sensor failure.
4 flashes is Upper element
5 flashes is Lower element

Troubleshoot section says:
1) Make sure access doors and insulation are installed.
2) Check elements for resistance of 5-25 ohms (if element has a short in center of element, it might not trip breaker)
http://waterheatertimer.org/How-to-test-water-heater-element.html
3) replace element and reset control system.
Buy ordinary 4500 Watt element from hardware store.
http://waterheatertimer.org/How-to-replace-water-heater-element.html

4) I also suspect the self-diagnostic control box.
Manual says: Repair parts may be ordered through your plumber,
local distributor, home improvement center, or by calling
1-877-817-6750.
You need serial number, product number and model number from label on side of tank.

Energy smart hot water heater not giving ample amount of hot water both elements ohm at 12.5


element-connection-450.jpg
For images and product information
For manual


You checked ohms, did you check for 240V across lower element when lower element is turned on?

Energy smart electric water heater
has a control box on top of unit. Water heater does not have typical thermostats that can be tested and replaced. Temperature sensors located above each element send information to control box through small black and red wires. Temperature sensor sells for about $40, but there is no test listed that shows how to determine when sensors fail.

Potential problems:
-Temperature sensor is not reading correct temp
-Control box not processing correct temperature information
-Selector on control box set to 2, 3 or 4
-Thermostat temp on control box set lower than 120 degrees F
-Sediment build-up starting to surround lower element so water doesn't circulate (see if drain valve runs full-open
