Contact Paloma/Rheem 866-720-2076. Super nice! I just called regarding mine. Having same problem Rheem Paloma sending parts out tomorrow overnite. Try turn it on/ off by moving tiny switch under the unit that tells you the temperature. Run your fingers along the bottom to find it. That is a temporary fix. Below is a website with all the error codes, so you know what is wrong. Good luck and blessings!

Before calling service technician, open following links for Rheem troubleshooting resources, including generic error codes and contact information for Rheem and recent manuals:
http://waterheatertimer.org/Troubleshoot-Rheem-Tankless-water-heater.html
http://www.fixya.com/tags/rtg_74pvn

Error codes are start place for troubleshoot, and multiple error codes can indicate bad PC board.
Same error code on one machine can be different cause and solution than another machine.

Error 76 is usually communication problem with remote control.
Disconnect wires from machine, and clean terminals is a start point.
Wire between machine and remote might be bad, or remote control is bad, or PC board or wiring connections are bad.

The problem might be solved by having technician catch the machine up on yearly maintenance.

Manual for same-similar product shows maintenance and troubleshooting and a few error codes, but not 76:
For the most part, the manual recommends calling service technician instead of offering DIY details.

I have Model PTG2-42PVN it shuts off and the remote flashes C7 and 76. What does this mean???


Could be the remote control. Disconnect remote and see if tankless works fine.

Probably bad PC board. Rheem will send new board and you can install yourself.

Bad PC board is kind of like the motherboard on your computer, so expect same level of performance after replacing motherboard ... which usually means the computer's days are numbered before another major problem.

C4 76


76 is a bad connection between the controller and the unit. try unplugging the controller and running it, also check the wiring between the two units. if that is not it. it means that one of the control boards it shot
