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

Water heater heats water and then cuts off. I replaced the lower element with a guaranteed for life element. It still heats up and cuts off. There is a control box on top that allows for an easy reset. ...


1) Bad thermostat or thermistor depending on model.
Whirlpool/Craftmaster/American energy smart has control box on top, and you can order parts from Whirlpool.

2) Copy following links to help identify product.
http://waterheatertimer.org/How-to-troubleshoot-electric-problems-with-water-heater.html
http://waterheatertimer.org/Whirlpool-Energy-Smart-electric.html

3) Add a comment with more detailed information:
You have electric water heater.
Unknown brand, possibly energy-smart.
Unknown control box.
Cut off? Do you mean 'reset' is tripped?

4) Whirlpool energy smart requires 10 gauge wire and 30 amp breaker.
Control panel may not function with undersized electric supply.
Control panel has blinking-light errors ... if no error code then maybe the control box is bad.

Troubleshooting whirlpool ee2h50rd045v water heater


1) Copy following links for whirlpool energy smart resources:
http://waterheatertimer.org/pdf/Energy-Smart-troubleshooting-guide.pdf
http://waterheatertimer.org/Whirlpool-Energy-Smart-electric.html

2) Control box is probably bad.
There are 2 types of control boxes for older-style energy smart water heaters.
You will need model number and serial number from label on side of tank to order from Whirlpool.

3) This older-type energy smart water heater is probably discontinued by AO-Smith, American, State, Craftmaster, Reliance water heater group that makes Whirlpool and Kenmore water heaters.
New generation energy smart offers interface with home automation and/or non-existent smart grid.
Older energy smart only offered potential interface with non-existent smart grid.

Can I run the hot water heater with a generator


Yes.
Ordinary electric water heater can run on any voltage from any direction (excluding volt/amp ratings below what can heat element coil).

Voltages include single-phase, split phase, and 3-phase residential/commercial voltages with either 50 or 60 Hz.
http://waterheatertimer.org/How-to-wire-water-heater-for-120-Volt.html
http://waterheatertimer.org/How-to-wire-water-heater-thermostats.html#3-phase

Install line fuse.
30 amp fuse would be required to prevent wires from overheating, and eliminate fire hazard.

This information does NOT apply to energy-smart electric water heater with box on top of heater, or newer energy smart with electronics, or to hybrid water heaters, or heat pump water heaters with delicate electronic circuitry.

Why it works like this:
Ordinary electric water heater thermostats are mechanical bi-metal switches and respond to tank temperature, and are not operated by electricity.
Ordinary generic elecrtic water heater thermostats switch electricity on-off using mechanical bi-metal switch.
Heat elements are simple coil of thermal wire that gets hot when voltage is applied.
The element will get hot when power is applied.

Whirlpool 40 gallon energy smart elecrtic water heater. The control board binks once, by the panel means system start up failure,but we still have hot water,but every time we use the hot water it starts...


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:

Our water heater is doing the same thing. . Before I replaced the board I checked the elements, both were about 13.5 ohms, after checking I made sure to replace all insulation and closed the access covers...


1) You have given good diagnostic information ... except brand and model number of water heater are missing.
Locate this information on label on side of tank.

2) 2 flashes for high temperature indicate you have Whirlpool or Craftmaster Energy Smart.
You have dual element 240V tank-type electric water heater with electronic control board and temperatures sensors.
Sensors can be ordered separately for $30 each.
Sensors seem like best suspect since elements test out and you have new control board.

3) Did you test elements for short to ground through center of element?
http://waterheatertimer.org/How-to-test-water-heater-element.html

4) Energy smart requires 10 gauge wire and 30 amp breaker. If wire or breaker are undersized, then I would expect chronic problems with electronics. I believe the requirement is so element draw or other factors don't starve electronic control board.

5) How it works: Energy smart is non-simultaneous water heater. Non-simultaneous means upper element turns on first. When upper temperature sensor is satisfied, control board cuts power to upper element and sends power to lower temperature sensor and element. So both elements are never ON at same time. Lower element runs until lower temperature sensor is satisfied. I do not know decision tree for how microchip processes the information.

6) I have examined this water heater and read the manual. I wrote following page, but have not conducted electrical testing on unit simply because it is controlled by micro-chip.
http://waterheatertimer.org/Whirlpool-Energy-Smart-electric.html

7) Sample Energy Smart manual:
Manual does not show how to test temperature sensors, but manufacturer might have more information. Manufacturer might have information how changing meter can affect their electronics.
I would guess undersized wiring would have greater impact than electricity turning off for 1 minute.
http://waterheatertimer.org/pdf/Whirlpool-energy-smart-electric-manual.pdf
Whirlpool 1-877-817-6750

8) 4500 Watt elements should test 12.3 ohms, so your elements check out fine.
Be sure to test for short to ground by setting multimeter to ohms, remove wires from element, and test each screw to bare metal part of heater and to metal base of element.
http://waterheatertimer.org/images/ohm-reading-for-emements.jpg
http://waterheatertimer.org/How-to-test-water-heater-element.html

9) The water heater industry changes very fast, so current manual is best place to start troubleshooting.
If you have different brand than shown above, then open following link to identify manufacturer's website:

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.

Whirlpool energy smart water heater


Two flashes means that the high limit temperature has been reached. Once this happens, the temperature control system will shut off. Make sure that all element access doors are in place. Push the "Push to Reset" button to restart the temperature control system. The water heater will self test for ten minutes before it will start to heat. If you get the 2 flashes again then you may need to replace one or both elements. Each element should measure 5-25 ohms.

The "thermostat" is the knob marked "Temperature Control". Make sure that the operating mode is set to 1,2 or 3.
