REPLACING THE SPARK IGNITOR WOULD BE MY FIRST GUESS .

The water heater is locked out. The following process should reset it.
1. Reapply power to the water heater and wait for 3 seconds for the system self-diagnostic check.
2. Within the first 30 seconds, the temperature dial must be rotated back and forth crossing the 120
degree mark at least six (6) times. This will reset the control and display a normal flash code
(slow blinking).

Sounds like a bad thermocouple. This part sends a millivolt signal to keep the gas valve open but shuts it off when it cools - or if something goes wrong with the ignighter - to prevent fires. It's easy to replace and not super expensive. See your local Rheem dealer.

That is a power vent failure code.
Rheem is aware of this problem and are changing systems as we speak. Call your Rheem dealer and demand the updated system.

There are many things to check. The single most important test is for 24V at the gas valve after the ignitor is supposed tp be on. 19 V or less and there is either a bad ground or the ingition control board has failed. (Wire ground problems are a high probablilty) PROBLEM #1 - HOT SURFACE IGNITOR DOES NOT GLOW RED (Remember to wait for purge time, 17/34 seconds, on models so equipped). Possible causes A. No main power B. Faulty transformer C. Faulty thermostat D. Faulty limit switch E. Faulty blower interlock switch F. Faulty hot surface ignitor G. Faulty ignition control Solution Step #1 Perform normal system checks of main power, transformer, thermostat, limit switch, blower interlock switch, and replace faulty component. Step #2 With power on and thermostat set at its highest position, check voltage between "TH" and "TR" on HS780 ignition control. If 24 volts is not present check output at transformer. If no, replace transformer. If transformer checks out OK look at other controls in the 24 volt circuit I.E.: thermostat, limit switch, blower interlock switch. Check for 120 volts between "neut" (L2) and "120" (L1). Check for 120 volts at the ignitor across "IGN" and "IGN" terminals on the HS780 ignition module. If 120 volts is present, PROBLEM #2 - IGNITOR GLOWS RED BUT MAIN BURNER WOULDN'T LIGHT Possible causes A. Improper ignitor alignment B. Faulty ignition control C. Faulty gas valve D. High inlet gas pressure E. Polarity reversed F. No earth ground Solution Step #1 Check for availability of gas at gas valve. Make sure the manual valve upstream of the gas valve and the gas valve are in the full on position. Also make sure gas is being supplied to the system at the proper pressure, too high will lock-up the valve. Step #2 Check proper polarity of "NEUT" and "120" on the ignition control by reversing the wires, if reversed gas valve will not open. If this does not solve the problem, replace wires as they were. Step #3 Check for proper ignitor position. Step #4 Check for a good earth ground by using a meter connected between L1 and furnace chassis. Should read 120 volts, if no, check and/or repair ignition Step #5 Check for 24 volts at the gas valve terminals; "1" and "2" on a 7200 series, "M" and "C" on a 7100 series, "TH" and "TR" on a 7000 series. If yes, check wire integrity or change the gas valve. If no, change the 780 series
Here is what the book says:
replace ignitor. If no, replace the 780 series module
ground wire or ignition control mounting screws.
CAUTION POLARITY MUST BE OBSERVED
ignition module.
That is pretty much all of the troubleshooting required.
