Flashing code 76 is lost communication between the remote and the burner control assembly CCA (circuit card assembly). The CCA is still under warranty if purchased within the last 3 yrs. Contact Rheem customer service and have your Mod. and S/N available....explain to the agent you are recieving - flashing code 76...they'll walk you through the process.

    Contact Paloma/Rheem customer (800-432-8373) support and notify them you are getting a code "76" error. Rheem has recently extended the warranty on the "Burner Control Assm."; which is your problem.

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.

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.

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.

Can you tell me why my heater turns off when I turn on my washer and the kitchen sink and its not just when Im washing its also when I shower.. and the error code is C76 or Double 00


No I don't know why it turns off and gives error code 76.
Those two things seem unrelated.
Before calling service technician, open following link for Rheem troubleshooting resources.
http://waterheatertimer.org/Troubleshoot-Rheem-Tankless-water-heater.html

My tankless indoor water heater has an error code C4 76


Error code 76 indicates a communication error with the electronic board and the unit. Call Paloma/Rheem with the serial number and model number of your unit and they will, in most cases, send you a new board with instructions on how to easily replace the board.
