My Rheem water heater is giving a ECO failure, How can I fix this?


Question posted under Rheem water heater.
Model number and gas valve are unknown. Add a comment.

Following information applies to typical tank-type gas water heater, and does not apply to tankless water heaters, boilers, indirect heaters, solar water heaters, etc or for electric water heater.

Electric water heater ECO is located on upper thermostat.
Open top cover and ECO can be reset by pushing in red reset button,
Or ECO can be replaced by replacing thermostat. Add a comment.

Open following link to see typical tank-type gas water heater ECOs:
http://waterheatertimer.org/images/Intellivent-ECO-900.jpg
http://waterheatertimer.org/images/Typical-gas-valve-500.jpg

The ECO will trip at 180-200 degrees F.
This happens when the thermostat fails, then the burner stays on, and the water will continue heating.

With most water heaters, the ECO is one-time use device and the gas control valve is replaced.
Some water heaters have resettable ECO, but the overheating problem has to be solved.
Each water heater is different.
Contact Rheem or read manual for correct procedure.

If you have intellivent gas control valve, open following links for typical service manual:

RHEEM 50 GALLON WATER HEATER,4 BLINKS THEN 2 BLINKS ,ECO FAILURE,UNPLUGGED HEATER STARTS UP AGAIN THEN FAILURE OCCURS AGAIN.


That is a power vent failure code.
Rheem is aware of this problem and are changing systems as we speak. Call your Rheem dealer and demand the updated system.

What is eco failure


E.C.O. is Emergency Cut Out, or some say emergency cut off, whatever. It is a safety item that will cut out, in case the thermostat malfunctions.Basically same as a high limit switch, cuts off power if temperature gets too high.

Light flashing - lockout condition - ECO failure


The ECO is designed to shut off the water heater in case of the water heater overheating. This is to prevent the water heater from exploding. I assume that you have a newer style residental water heater or a commerical boiler. The ECO is a fuseable link that is built into the control and located at the thermostat probe. If the water heater overheats then this link will melt cutting the circuit on the millivolt system(residential) or 24volt system(commercial boiler). If you look under the water heater control(where the temp adjustment is) there are usuall two wires that go from the control to the water heater. These are the ECO wires. Verify the wires have not been cut or damaged. If these wires are cut or damaged then the ECO circuit will be incomplete and you will get the ECO lockout failure. Also make sure that the flame lock-out switch is not tripped. It will be located at the burner compartment cover and have two wires going to it. Most have a little button in the center. These are to sense high heat and one might have tripped closing the circuit. You can push this little button to re-set the switch. If you feel a little "click" then the switch was probably tripped. If it does not have any button then it might be "self resetting". To test that switch use a continuity tester and the circuit should be closed. If these switches are working then the fusable link for the ECO is probably bad from the water heater temp getting too high or was defective and failed. This will require you to remove the water heater control valve and replace the fusable link. If you do not have experience with this I suggest you call a licensed plumber to make the repairs. If this repair is improperly done it could void the warranty on the water heater and/or cause property/personal damage or injury. There is a possiblilty that your water heater thermostat had failed causing the ECO to trip. If that is the case then the ECO safety did it's job.

My Superflue water heater is flashing Eco failure. What is this? What do I do?


Hi,
The ECO is short for emergency cut off.
The ECO is either tripped or it went bad. You may be able to reset it or you will have to contact a rep the sells your heater to get a new part. Some are resetable and some are not... not sure which you may have. The reset ones will have a little red button to push in the center.
The next rpoblem is to figure why the ECO went or tripprd in the first place. There is probably a reason or a cause. When you refire it make surte you donot have flame roll out and proper venting. Also make sure the the thermostat works and is not letting it get too hot.

I hope that this will help you to solve your problem!

Thanks for using Fixya!!

ECO failure. Replaced the gas control thermostat & vapor sensor


It sounds like your gas/air mixture needs to be adjusted. The flame should have just the slightest amount of white, at the very tip. The rest should be evenly blue. There is an air vent adjustment in the line to the burner, right after the gas input.

I dont know what ECO failure means or how to fix it.


This water heater is equipped with a control which has a built inE.C.O. (Energy Cut-Off). The E.C.O. will shut the gas off,
should the outlet water temperature exceed 200 F. If the
E.C.O. has tripped, the entire gas control must be replaced.
For gas control replacement, contact your local gas utility, or a
qualified service technician. The replacement control must be
an identical model to the control which has been removed.
