Copy following link for error codes and Rheem-Paloma tankless troubleshoot.
http://waterheatertimer.org/Troubleshoot-Rheem-Tankless-water-heater.html#error
Add a comment and say if this is new installation.
Call Rheem and hear them tell you to call the tankless installer, or hire local service technician to check your tankless computer that heats water, and catch up on required monthly and yearly maintenance. For example cleaning burner and flame rod, or replacing bad flame rod, or installing correct gas line, or checking gas pressure etc.
Fix any tankless problem yourself, any brand tankless, same day for $385, by replacing 1 part: the whole thing:

Do not install tankless.

SOURCE: PALOMA PTG-74PVN-1 Code C8 12 my water heater

C8 is the last stop in the point of burner ignition and a total of eight error codes. Error code 12 is a supplemental code that means your LP gas supply is too low...have your LP tank service and try again.

HTH,

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.

Error Im getting is C8 82


Before calling service tech, copy following link for Rheem-Paloma troubleshoot resources:
http://waterheatertimer.org/Troubleshoot-Rheem-Tankless-water-heater.html
C8 is usually the PC board, or could be failed gas solenoid valve.
82 is gas-type-data-failure = program PCB for proper gas type, or proper altitude above sea level.

If this is new installation, Rheem-paloma might tell you to contact the installer.
If this is older tankless that worked before, then things point to failed PC board. Rheem-paloma may send you new PCB for free if unit still under warranty period for defect parts.

Rheem does not post service manuals, but will send instructions.
Hopefully the success rate for replacing your main PC control board will have better outcome than expected when replacing motherboard on your computer.
Perform regular maintenance to avoid some common error codes.

I have a paloma tankless water heater about 3 years old model PTG-74PVN and it works for 2 minutes and shuts off with error code C4 and 13 flashing. (City water pressure is fine)Can anyone help? Thanks...


I had the same problem with my Paloma a year and a half after installation...contacted Rheem customer service (800-432-8373) and they recommened a local installer in my area. The technican diagnosed the problem as the "flow control valve"; he managed to get Rheem/Paloma to cover the part under warranty...I only had to shell out the money for the install.

However, if you're fairly capable, they will email you a step-by-step process on how to solve the problem yourself. They'll provide assistance through the process over the phone as well.
