Pop-off operated suddenly on elec ops. Went to LP ops & same problem when water heats. Help!


What you are referring to as the "pop off" is the OVER-TEMP SAFETY DEVICE, which is designed to prevent the unit from overheating (and potentially exploding). It is infrequent that these fail but they sometimes fail. As a temporary measure, lower the temperature on the thermostat to a point below where the over-temp safety is triggered.

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:

Low voltage to eco from switch board will not hold valve open


That 12VDC voltage comes from battery and/or converter. Try unhooking battery while plugged in, and see if lights stay bright, as well as check voltage at screw terminals where fuses are in fuse/breaker panel. I f voltage low from converter, check the main fuses at converter. Be sure to check all fuses to circuits as well. You may have a bad or corroded connection from fuse panel to ECO as well. Remove wire from opposite side of ECO where it runs to gas valve, and see if voltage returns to acceptable range, indicating poor connection to valve, or valve drawing too much current.
Let me know what you find.

I have installed a new control valve assembly on my suburban water heater model SW6D and cannot get it to relight I have no power is there something I should be doing to reset this/


Check for 12 VDC at terminals on ECO and ( Therm)ostat. You should have power on both sides of each. ECO or thermostat may also have a reset pin in between spades that tripped as well, so push it in to be sure as well. If you have power on one side and not the other, replace it. If no power at all, start back at fuse panel, then to switch and out of switch.

The red button keeps poping causing the hot water heater to shut off. I have to constantly reset it.


The red reset button or ECO or energy cut off turns off power to electric water heater.
The ECO responds to temperatures in excess of 150 degrees F.

Preliminary work:
You can use thermometer to check water temperature immediately after ECO trips.
Compare water temperature against the thermostat setting.

There are 4 things that can cause ECO to trip:
1) Bad thermostat is sticking and letting element continue heating water, or ECO is reading incorrect temperature.
2) Factory installed insulation and cover missing from tank, and thermostat is exposed to cooler air and misreads tank temperature.
3) Element shorted to ground in center of element. This completes 120V circuit to ground which will cause element to continuously heat the water.
4) Loose wire near ECO causing high-heat electrical event.

Solution:
Check for missing insulation.
Check screw terminals for signs of high heat and burning >> tighten screws.
Replace both thermostats using detailed instructions given on link below.

If the problem continues after replacing thermostats, more troubleshooting is needed:

Atwood 10 gallon H2O heater- replaced thermal couple and electrode spark and sensor but heater comes on with switch, heats water for 10 to 15 mins then burner goes out. Can hear a couple of switching...


I'd check that ECO and thermostat discs are making contact properly with tank.Just peel back foam cover on outside of tank that has ECO and THERM marked on it. If they are installed correctly, replace them.
