SOURCE: how to correct error code C-7 on my RTG-74PVN Rheem Pronto

I had the same problem and called the manufacturer. The error code C-8 was followed by the number 76. They told me to disconnect the thermostat/digital display from the main unit. This was fairly simple to do by removing the front panel. The unit works steady now without shutting down after a few minutes. The help desk told me that the main circuit board needs to be replaced for the unit to work with the display and that they would mail me one asap. At least we have hot water again.

SOURCE: Rheem water heater turns off by its self

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.

SOURCE: Rheem Pronto RTG-74 error code C4

Error code 13 is "oxygen depletion sensor" activated.
The first number is a sequence indicator.
If you need the training manual I have it and can send it to you.
I got Rheem to send it to me a while back and it is a big help when working with these units.
It covers th RTG-42, 53, 66 and 74.

SOURCE: Error code 13 (air flow) tankless H20 Rheem

Have 2 of these Rheem units in my house. Both had this same error code within 30 days of each other. And my neighbor has 2 units as well - and guess what - 2 months after mine stopped working because of the code - so did theirs. It is not something that can be fixed. It is a manufacturer's defect - and it looks like Rheem has yet another class action on their hands (like the one for the RTG - 74 PVN). They need to do a recall to repace these units.

Rheem rtg-53pvn will not turn on and heat water when hot water is turned on - no error code - remote just goes off like the power is off


Before calling service technician, open following link for Rheem troubleshooting resources including Rheem chat:
Rheem will suggest you catch up on required yearly maintenance which would cover most causes for common error codes, and cover cause of no error code including plumbing problem or loose wire or PC board failure. Combination of problems can also cause failure and these issues would be covered by general maintenance.

Check that appliance is grounded.
Check igniter wires and harness for damage.

Other causes: Gas inlet solenoid valve, bad igniter, solenoid valve, flame rod.
