Error code C4 76

Error 76 is communication fault with remote control, or bad PCB board.

Copy following link for Rheem tankless troubleshoot:
http://waterheatertimer.org/Troubleshoot-Rheem-Tankless-water-heater.html

Call Rheem, and they will recommend service technician.
800-432-8373

Make sure your unit is serviced yearly to prevent common error codes. Which defeats the robust $100 expected yearly savings from owning a tankless water heater.

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.

I have a poloma model/ pt62-42pvn its flashing error code c4 76 i have had no hot water for six days now need help

1) Before calling service technician who can test parts, open following link for Rheem resources including error codes, Rheem chat and phone number, possible manual:
If local technician cannot solve problem, Rheem can probably recommend a person.
http://waterheatertimer.org/Troubleshoot-Rheem-Tankless-water-heater.html

2) Error codes are start-point for troubleshooting.

3) Multiple error codes can indicate PC board failure.
If your computer motherboard fails, most people feel the computer is compromised even after motherboard replacement.

4) Error code C7-76 is communication error with remote, and can include bad remote, bad wire to remote, loose wire, or bad PC board.
http://waterheatertimer.org/pdf/Rheem-error-code-C7-76.pdf

5) Error C4-13 can include part failure, vent problem, oxygen depletion, and can also include PC board failure.
http://waterheatertimer.org/pdf/Error-code-13.pdf

6) Tankless routine maintenance manual:
http://waterheatertimer.org/pdf/Tankless-maintenance.pdf

7) Some posts about tankless concede that qualified technician was unable to repair unit.
Solve most tankless problems yourself, same day, for about $350.

We have enjoyed a Rheem Thermostat and a Paloma Eco Sense tankless gas water heater #RTG-74XN-2 for 2 and 1/2 years, but now there are error codes flashing and resetting the thermostat doesn't hold. ...

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.

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!

Communication Fault with Remote Control Check remote control wiring for loose or damaged connections. Bypass remote control cable by connection remote directly to remote control terminals on PCB (replace cable if found to be faulty). Replace remote control. Replace PCB
