Question about Rheem Tankless Hot Water Heater Rtg-74pvp-2 7.4 Gpm

1 Answer

74pvp-2 7.4 Gpm has a continuous flashing 13 error code even when remote is off! It only goes off when i shut the power off. I checked the burners but they are clean and i think the vent may have allowed water condensation into the machine. Anyone have any experience with this?

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:

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.
