Energy smart system light flashing one time

The green light flashes and clicks,one time, for about 30 minutes different times of the day, the label on top shows that one flash means start up failure. We still have hot water, but we don't want it to quick working, and be without hot water. Thanks

If you still have a warranty, call the manufacturer and they will send you a new brain for FREE, You just half to pay the shipping. I just replaced one on my Mother-in-laws. They stated that there were problems with the brains. It is very simple to replace.Just make sure you have the breaker turned off.

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.

Replace thermistors.
Remove upper and lower covers, They are located under the foam insulation. Cut back insulation. Insulation must be put back when finished.
Call Whirlpool for parts, and they will also send instructions.

Water in basement in flood that covered the lower element. When power was turned back on, the green light on the top of the heater was blinking twice. When I hit the reset button, it is now blinking...


Yes sensor should be replaced along with lower element.

1) Manufacturer's say that flooded water heater should be replaced: Call homeowner's insurance company.
http://waterheatertimer.org/Flooded-water-heater.html

2) Brand of water heater is not known, but it could be the American or Craftmaster or Whirlpool energy-smart electric with control box.
http://waterheatertimer.org/Whirlpool-Energy-Smart-electric.html

3) With energy-smart:
1 flash is start-up failure, and 3 flashes is sensor failure.
The moisture probably shorted element and/or lower sensor.

4) The moisture inside tank will take long time to dry out, especially since the foam insulation is wrapped tight. To dry out element and sensor, you have to remove cover and insulation over element, but if you leave insulation off and run water heater, then the sensor is exposed to cool outside air and will not read temperature inside tank.
Plus a wet water heater is electric shock hazard.

You might be talking about Whirlpool energy smart electric.
The error diagnostic lights flash a code: the code decipher is printed on the diagnostic control box on top of heater.
Call Whirlpool: you need model number and serial number from label located on side of tank.

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.

The water heater does not react to lowering the temperature...water is above 130 degrees... This is a whirlpool energy smart residential water heater that was bought and installed in Mar of this year. It...


Product features show on link below
http://waterheatertimer.org/Whirlpool-Energy-Smart-electric.html

Energy smart manual shows troubleshooting chart on page 14
http://waterheatertimer.org/pdf/Whirlpool-energy-smart-electric-manual.pdf

Initially I would guess the temperature sensor is bad.
However indicator light would flash 3 times.
And since both elements have a temperature sensor, it's unlikely that both would go bad at same time.

That suggests the Self-diagnostic Control Box located on top of heater is defective.
Turn off power at the circuit breaker and see if unit resets correctly.

Manual shows 1-877-817-6750 number for Whirlpool parts and warranty.
Your unit is still under warranty, so control box and other parts should be free.

Keep in mind this water heater requires 10 gauge wire and 30 amp breaker.
If you are running smaller wire or smaller breaker, that could affect long term operation of electronics.
I guess this requirement is so voltage drop from element turning ON doesn't starve electronics in control box

On the control panel, the Red and Black wires connect to 240V from circuit breaker.
Wires appear to pull out of socket using needle nose pliers. It will be important to keep wires in same order.
Take photo of your wiring before disconnecting anything.

To order parts, you must give serial number located on label on side of tank.
Serial number will identify your specific heater to person answering phone at Whirlpool.
Installation part should come with instructions, but ask the person at Whirlpool what steps they took during training. Whirlpool rep might have helpful tip they learned during training.

Add a comment and let me know about your transaction with Whirlpool so I can pass it along.

Whirlpool Energy Smart Water heater - light is solid green then every now and then blink a couple of times then go solid again.What does this mean?


2 flashes = high water temperature (the water heater comes set at 120, and you can set it lower or higher)
3 flashes = sensor failure (temperature sensor similar to a thermostat on regular water heater)
4 flashes = upper element
5 flashes = lower element
Links below are for Whirlpool manuals
http://www.whirlpoolwaterheaters.com/support/Manuals.aspx
http://waterheatertimer.org/pdf/Whirlpool-energy-smart-electric-manual.pdf

The water heater is working right now.
If the elements go out, they are available at any hardware store.
The temperature sensor is easily replaced and can be ordered from Whirlpool.
You might want an extra temperature sensor on-hand so repairs are not delayed.
Link below shows the product in detail.
http://waterheatertimer.org/Whirlpool-Energy-Smart-electric.html
Let the water heater do its job until it fails.
