SOURCE: tankless water heater error code 11

I was having the same problem untill I reallized it was my venting system. Test the water heater with no vent on top. Disconnect the vent pipe from the water heater and try turning on the hot water. the water heater needs a special adapter to vent the direct vent water heater. One other thing you can check is the gas pressure in your home. You have to have between 7 and 8 WC (water Column) for the tankless water heaters. You can call your gas supplier to find out what you have.

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.

I have a paloma tankless water heater ptg-74pvn-2 that gives me the error code c2 11. looks like everybody has a problem with this. what can i do to fix it, surely enough they should have some easy way of...


Easy solutions for C2 11:

Rheem is one of the big manufacturers but has disproportionate number of questions at fixya since they try to funnel problems through service techs instead of posting do-it-yourself service bulletins. People want do-it-yourself service bulletins, as appear on the Bosch site for their products. Easy-fix in this sense would be to buy Bosch, and read service manuals aforehand to see if you have testing skills and equipment to maintain and repair tankless water heater.

Easy solution for C2 11 Rheem problem is don't install gas tankless water heater, since all costs are energy and tankless are expensive to install, maintain, repair, and replace for the mere savings of 1-8 per month.

Third solution for C2 11 no-ignition is to clean burner and combustion parts, and sand carbon off the igniter, on a yearly basis, as recommended in manual.

Fourth solution is to call a qualified service technician each year as recommended in manual, and have technician fix problem and catch water heater up on recommended service. This person can check other causes for C2 11 such as bad igniter, bad gas solenoid, low gas pressure, air in gas line, improper unit grounding, bad wiring, bad sensors, etc.
This check-up can also make sure vent drain is working properly and that acidic water vapor and other resulting combustion by-product are going into the household drain and eventually out to sea instead of dripping down into the heat exchanger causing rust and premature failure of exchanger.

Next solution will not solve C2 11 error code, but can address other error codes before they happen: Maintain water heater on yearly and monthly basis as recommended in manual. This is good for folks who like projects.

I have a Rheem rtg-74pvn-2 tankless water heater installed in 03/09. Intermittently the hot water stops when only the hot water tap is on. No error codes appear. Bill W.


Before calling service technician, open following links for resources including Rheem chat and possible manual:
http://waterheatertimer.org/Troubleshoot-Rheem-Tankless-water-heater.html
http://waterheatertimer.org/pdf/No-Error-Code.pdf
http://waterheatertimer.org/Crossover.html

Typical tankless manual says to have yearly service which includes checking household plumbing, gas supply, vent and condensation, check sensors for loose wires, clean and inspect burner parts and ignition factors etc.

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)

No hot water. Constant beeping at the tank. Tempature gauge flashing 11.


Before calling service technician, open following links for Rheem troubleshoot resources including Rheem chat and typical service manual and typical product manual.
http://waterheatertimer.org/Troubleshoot-Rheem-Tankless-water-heater.html

Error codes are start place for troubleshooting:
Error 11 is 'gas is inadequate' or 'ignition failure'
Open gas valve so handle is parallel with gas line.
Bleed air from gas lines.
Check that appliance is grounded.
Check igniter wires and harness for damage.
Check that vertical vent length does not exceed limit.
Other causes: Gas inlet solenoid valve, bad igniter, solenoid valve, flame rod.

C2 11 code


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

Error code C2 11 is '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 paloma tankless gas has a error code c2 11 c4 12 why


Open following link for useful troubleshooting information:
http://waterheatertimer.org/Troubleshoot-Rheem-Tankless-water-heater.html

Error code 11 is 'No ignition'
http://waterheatertimer.org/pdf/Paloma-Tankless-Error-Codes.pdf

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.

Error code 12 is 'Flame Failure'
Ensure you have gas to the appliance.
Ensure gas type and pressure are correct.
Bleed all air from gas lines.
Ensure flame rod wire is connected.
Check flame rod for carbon build-up.
Ensure gas line, meter, and regulator are sized properly.
Ensure appliance is properly grounded.
Check gas solenoid valves for open or short circuits.
Check power supply for loose connections.
Check power supply for proper voltage and voltage drops.
Disconnect remote control.
Disconnect and re-connect all wiring harnesses on unit and PC board.
Ensure proper venting material was installed.
Ensure condensation collar was installed properly.
Ensure maximum vertical vent length does not exceed allowable limits.
Ensure maximimum horizontal vent length does not exceed allowable limits.

Range of causes are part failure, gas pressure loss, air in gas line, improper installation of gas line or vent, 120V power to unit is disrupted or unit not grounded, circuit problems, venting problems, remote control, wiring to PC board, board failure, carbon build-up on flame rod, short circuits on gas valve solenoids.
The fact that you have error code tends to eliminate your plumbing as culprit, the error code does not mention air supply, otherwise it looks like every possible cause is on the table.

Add a comment with your experience so other with same-similar problem can benefit.

Also take advantage of fixya expert assistance live.
For a price, expert works with you while you work on water heater or any do-it-yourself project.
Fixya is always less expensive than a service call.

I have error codes "C2"


Open following error-code link in downloadable pdf for your files:
http://waterheatertimer.org/pdf/Paloma-Tankless-Error-Codes.pdf

Error code 11 has to do with ignition/gas/gas pressure/electrical grounding.
This can be caused by internal part failure or combination of internal or external factors.
I suggest reading pdf, and then calling service technician who specializes in your brand.

Open typical manual to review required regular maintenance for tankless on page 29
The word maintenance is used throughout manual, indicating that tankless are a yearly budget nuisance
