Question about Rheem RTG-53PVN Indoor Natural Gas Tankless Water Heater for 1-2 Bathroom H

Open Question

My Rheem tankless water heater model RTG-95DV will not ignite, my remote gives a error code 11. I checked the gas valve it is opened all the way, I can also hear the igniter clicking. Looking at the circuit board there is a LED light it will start flashing when I try to start the heater it continues to flash after the heater is shut down, what is this light for?

SOURCE: Rheem water heater turns off by its self

Flashing code 76 is lost communication between the remote and the burner control assembly CCA (circuit card assembly). The CCA is still under warranty if purchased within the last 3 yrs. Contact Rheem customer service and have your Mod. and S/N available....explain to the agent you are recieving - flashing code 76...they'll walk you through the process.

SOURCE: How do I delete the stored error codes on my Rheem

Some error codes cannot be reset...Example would be P/S failure on the PCB. Any other error, if you remove power for approx. 2 min - error should clear. - if not you need to contact Paloma/Rheem customer (800-432-8373) support

Rheem Integrity 20 not always lighting. Showing code C2 11

http://waterheatertimer.org/pdf/No-Error-Code.pdf

C2 11 is no ignition.
Clean combustion parts yearly as recommended in manual is first step.
Other causes can be loose wiring, bas gas valve, dirty air intake, bad venting, bad sensors etc.
Test these parts using service manual. Call Rheem since Rheem does not post service manuals.

I am getting a C2 11 code on my eco sense tankless water heater. There is also a flashing 24, any ideas? Thanks


Multiple error codes can mean PC board failure.
C2 11 is no ignition.
Error 24 is malfunction of operational switch: "press max or mim button on PC board, or replace PC board." On some models, max and mim button can be located just above dip switches, and rotates with screwdriver. See diagram in manual.

Code 11


Before calling service technician, open following links for Rheem troubleshooting resources including error codes.
Error codes are considered start-point for troubleshooting.
http://waterheatertimer.org/Troubleshoot-Rheem-Tankless-water-heater.html
http://waterheatertimer.org/pdf/ErrorcodeTroubleshooting.pdf

Error 11 is no ignition.
This problem can probably be solved by routine yearly maintenance shown in instruction manual which recommends: Yearly cleaning, adjustment and inspection of burner and combustion parts.
The yearly maintenance would check incoming gas supply, venting, wiring and grounding, and burner and ignition parts.
All gas water heaters today require same maintenance: tankless require yearly, and tank-type require periodic (1-3 years)

Remote flashing Code 11


Before calling service technician, open following link for Rheem troubleshooting resources:
http://waterheatertimer.org/Troubleshoot-Rheem-Tankless-water-heater.html

C2 11 is: "inadequate gas.
Open the gas shutoff valve all the way"

Another source for error 11 shows: "no ignition"
"Ensure you have gas to the appliance.
Ensure gas type and pressure are correct.
Bleed all air from gas lines.
Ensure gas line, meter, and regulator are sized properly.
Ensure appliance is properly grounded.
Check gas solenoid valves for open or short circuits.
Ensure igniter is operational.
Check igniter wiring harness for damage."

There is no service bulletin covering how to perform these actions.
Rheem will ask that you call qualified service technician, who can give you tips and tricks for keeping the unit working, including opportunity for yearly service that will eliminate the expected $1-8 monthly savings from owning tankless.
Read manual for yearly maintenance needed to keep unit working at prime efficiency.

My new tankless WH stopped working. It gives hot water for about 15 sec, then starts flashing C7 12 or C2 11. How can I fix this, We had it for a month now & it worked before.


11 The Gas Shutoff Valve is not opened
completely.

12 Gas Service has been interrupted.
LP Gas is running low. (LP models only)

I think C7 is where the startup sequence ended...and then you get the error code

If less than a month old...contact your customer support
