Rheem/Ecosense, ECO-180DVP, tankless water heater,flashing code 11


Unknown if this is new installation.
New installation, you may need more gas to the unit.
Call the propane dealer.
The dip switches for selecting LP or NG may be set incorrectly.

If this installation worked before and stopped working:
Before calling service technician, copy following link for troubleshooting resources:
http://waterheatertimer.org/Troubleshoot-Rheem-Tankless-water-heater.html

Error code 11 is ignition failure.
Keeping up with regular maintenance can eliminate a lot of common error codes, but the cost is greater than expected savings from owning a tankless.
Regular maintenance such as cleaning combustion parts, checking gas pressure, testing solenoid gas valve, sanding carbon off the igniter, checking igniter wiring harness, etc.

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:
http://waterheatertimer.org/How-to-adjust-temperature-on-water-heater.html#intelli
http://waterheatertimer.org/pdf/Intellivent-service-manual.pdf

Richmond 3360 gas water heater pilot won't stay on


Open following links for pilot and troubleshooting resources:
Problem could be bad thermocouple, thermocouple not sitting in pilot flame, pilot orifice needs to be cleaned, water heater needs more air, dirty air intake, hot attic environment, backdraft blowing out pilot, or bad gas control valve.
If you get flame, then ECO is not tripped.

Model #22v30FN serial# rhu08898u6983 mfg date 20 aug 2009 waterheater won,t light (installed sept 2009)


Gas water heaters are a huge field:
More information is needed for correct do-it-yourself answer. Add a comment and include what steps you have taken and what you observed at the pilot light. Include description of gas control valve.
The combustion parts may need to be cleaned, the thermoscouple could be bad, misaligned thermocouple, the system locked out from FV flammable vapor event, or overheating caused ECO energy-cut-off to trip, or air in gas line, low gas pressure, or dirty air intake, bad venting, improper venting, bad gas control valve, negative pressure, tight house, lack of combustion air, hot attic, exposure to chemicals in air, rusted parts, etc.

Add a comment any time.
Or contact Rheem at 1-800-432-8373

Can u tell where the reset switch is located i this model or the g91-200


The reset is the ECO.
I can get you started but have not worked on this water heater.

Open following generic manual for Rheem commercial gas water heater:
http://waterheatertimer.org/pdf/Rheem-Commercial-Gas-ECO.pdf
http://waterheatertimer.org/pdf/Rheem-Commercial-Gas-Universal.pdf

Troubleshoot tree on page 20 shows series of tests and actions to restore ECO or determine if gas control valve is bad.
Maintenance steps start page 11. Gas water heaters today should receive yearly maintenance.
