Rheem, Richmond, Ruud, and Paloma are all the same manufacturer. After about 9 months, my tankless RTG-74PVN started giving me error code 11 and cold water!. I fixed it by cleaning the burner, as shown in this video:

Error code c7 and 12 on an ecosense natural gas water heater


Before calling service technician, copy following link for ecosense tankless troubleshooting resources.
C7 is communication failure with remote, and C12 is flame failure.
Multiple error codes could mean bad circuit board, loose wire, low gas pressure, or simple communication problem with remote control.
