I am getting a C2 11 problem error on my Rheem tankless water heater, What that mean?


Just how much did you investigate this on the internet before asking here? I Googled " Rheem C2 tankless water heater" and found http://waterheatertimer.org/Troubleshoot-Rheem-Tankless-water-heater.html. Look under Error Codes. Code 11 refer to gas supply/ignition. If you don't know much about tankles water heaters or gas ignition, call a Rheem Tech.

Copy following link for Rheem tankless troubleshoot resources, including error codes, manuals, and general information for maintaining your tankless computer that heats water.
http://waterheatertimer.org/Troubleshoot-Rheem-Tankless-water-heater.html
Multiple error codes can indicate failed PC board. Rheem will send PC board... so your computer-that-heats-water might have failed motherboard.
Continual maintenance can help avoid common error codes, but some problems are insoluble and chronic.

I have a paloma PTG 74PVP-2, error codes C2 14 flashing?


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

Error 14 is low manifold pressure, cracked heat exchanger, restricted air flow.
C2 can be dirty combustion parts, bad gas solenoid valve, bad circuit board.

Combination of these two error codes implies possible PC board failure, which is similar to failed motherboard on computer.
Suggest that service technician perform the required yearly maintenance to see it that fixes error code.

Getting a error code C2 82 on PTG-42PVN / RTG2-42PVN Natural gas indoor


This error code will occur for two reasons:

1. The heater has lost its programming and you will need a new programming chip from Rheem. (866) 720-2076
2. The igniter module is located behind the Printed Circuit board and will need to be relocated.

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 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.

RTG 74-PVN-2 Rheem tankless water heater. Works fine for a month or so at a time, then I get C2 - 13 error code. Did I hear this model was recalled?


Before calling service technician, open following link for Rheem troubleshoot resources including error codes and typical manuals.
http://waterheatertimer.org/Troubleshoot-Rheem-Tankless-water-heater.html
Recall website:
http://www.tankless-recall.com/tanklessSearch.aspx
Error code C2 13 call Rheem.

Read manual cover-to-cover to make sure your tankless water heater receives yearly maintenance required for unit to continue working.
Tankless are maintenance heavy which can quickly eliminate any promised energy savings unless you de-lime and troubleshoot and read tips-and-tricks others have written and glean information from service technician who visits your house. Mostly glean how much tankless repairs and parts cost vrs buying whole new tank-type gas water heater at local box store, since all costs are energy.

I keep getting a C2 11 error code. Unit lights and immediatly goes out showing that error. At other times it operates fine. The problem seems to be occurring more frequently. It has been in service...


that error code means not enough gas.
however, there might be something going on with your venting. it could be sucking exhaust air back into the unit. this will cause the same error code.
if your problem is intermittent, then I would suspect the venting to be the issue.
