SOURCE: Rheem RTG 53 PVN with fault codes C4 or C7

I had the same problem with my tankless waterheater (flashing c4 76 alternately). I called Rheem
tech support and they had me 1 power down the remotepanel 2 unplug the unit from the wall 3 remove the cover 4 remove the wires for the remote panel from the circuit board and pull the twisted pair that goes to the remote out from the bottom of the unit. 5 reinstall the cover 6 plug the unit back
into the wall and turn on the hot water see if it works. It did in my case and they are sending me a new remote panel. I hope it helps.........

SOURCE: No hot water from tankless water heater. Bliniking Readout

http://www.rheemtankless.com/content/tankless/rheem/help.shtml

This is there website.Above.
Use the live chat to ask them, the code you listed does not seem to correspond to there code list, the only code that does is code 76,
which is a problem with the remote control not talking to the unit.
So your best bet is to tell them the error.

SOURCE: Paloma PTG 74PVN Tankless Water Heater

did you check the filters on the the water valves, i am not exactly sure about your codes that are shoeing but if you could read it and post them, i know on some of the units 76 means there is low water pressure and the filters are behind 2 caps one on each side above the shut off valve take off the caps and remove the screens, clean them and replace them ,, make sure you turn off the water on both side first or you will get wet

Tip

Get hot water from your Rheem tankless during a code 76 error


This doesn't always work, but on the Rheem tankless Gas/Propane water heater, if you're experiencing a code 76 error; disconnect the remote control unit (either from the water heater or the remote) by lifting the wires for the remote connection. Typically you'll get a C1-C8 error code, followed by a code 76; if you're getting a straight code 76 and nothing else, this procedure probably won't work.
Code 76 is a total power supply failure on the printed circuit board (PCB) assembly, which is the communication/power supply for the remote control unit. But, if you're getting a supplemental code (C1-C8) this procedure will most likely supply you with hot water until the replacement PCB arrives.

C4 76 error code on richland waterheater


Richland tankless is made by Rheem.
C7-76 is communication fault with remote.
Turn off power at remote and wait 5 minutes, turn power back on at remote, and see if problem clears.
If problem continues, read below:

Before calling service technician, open following links for troubleshoot resources including error codes, Rheem chat, typical maintenance manual:
http://waterheatertimer.org/pdf/Rheem-error-code-C7-76.pdf
http://waterheatertimer.org/Troubleshoot-Rheem-Tankless-water-heater.html

Tankless water heater, more than any other type of heater, need to be maintained.
Maintaining tankless will probably not affect C7 76 fault code, but can prevent many other common error codes.
