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

1 Answer

Error code c7 12 with red light on circuit board. The unit has worked great for 2 years and is getting plenty of propane. I burns for 5-10 seconds and goes out. The blinking red light on the circuit board is on whether the unit is running or not.

Tip

Get hot water from your Rheem tankless during a code 76 error


This doesn't always work, but on the Rheem tankless Gas/Propane water heater, if you're experiencing a code 76 error; disconnect the remote control unit (either from the water heater or the remote) by lifting the wires for the remote connection. Typically you'll get a C1-C8 error code, followed by a code 76; if you're getting a straight code 76 and nothing else, this procedure probably won't work.
Code 76 is a total power supply failure on the printed circuit board (PCB) assembly, which is the communication/power supply for the remote control unit. But, if you're getting a supplemental code (C1-C8) this procedure will most likely supply you with hot water until the replacement PCB arrives.

Code 73 on a noritz tankless propane water heater


73 code is a circuit board error. It typically occurs if you connect or disconnect anything in the heater with power on. Try disconnecting electricity for 20 seconds to reset the unit. If the problem continues, you may need to replace your circuit board.

Remove power source from the unit. If remote control2.gif 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 support2.gif.

If this helps, please indicate so.

After a few minutes of burner heating the water, gas shuts off.


A couple of things to check:

If possible, remove the pilot gas assembly and clean the gas jet and thermocouple - they can get carboned up and stop working properly. Make sure the pilot flame and deflector is aimed properly and making the thermocouple glow red hot. If the problem persists, you may want to replace the thermocouple and also check the propane regulator.
