Question about Rheem RTG-53PVN Indoor Natural Gas Tankless Water Heater for 1-2 Bathroom H
Remove power source from the unit. If remote control is installed; remove cover and lift the control wires on the terminal...can be accomplished from either end.
Restore power and see if unit functions normally.
Contact Paloma/Rheem customer (800-432-8373) support and notify them IF you are getting a code "76" error. Rheem has recently extended the warranty on the "Burner Control Assm."; which is your problem. The C4-C8 portion of the error code, is where the unit stops the ignition process...burner fails to light, or gives you intermittent hot water. In either case, contact customer support.
If this helps, please indicate so.

My RTG-74PVN tankless is 3 1/2 years old. It started giving me the "76" error code 1 day ago. I disconnected the Remote from the main unit and it's working. I then called Rheems tech support, they verified the problem was the circuit board in the main unit. They are sending a new circuit board to a local contractor for installation at no charge to me. I wasn't even put on hold. I am very pleased with the service. (not with the bad circuit board)

Unplug your controller and see if it happens. if it doesn't then you know its a bad connection between the tankless and the controller if not the PCV board could be having problems
