Question about Rheem 50 Gallon FVR NATGAS Water Heater 6YR 22V50F1

PVS50 rheem power vent water heater do not reignite/restart/kick

I have 3 year old Rheem PVS50. It works fine once plugged in to power supply. After it reaches the desired temperature it shuts off also. But it does not restart/ reignite/ kick back once water is consumed and it is again below desired temperature set in thermostate. I need to remove power supply and reconnect it. then it starts again and problem repeats.
The small red LED shows "two blinks and off for a while" signal when it is not working. The LED constantly blinks when working good.

I actually just installed one of these the other day, I found that the ignitor wires were straped to the gas inlet and they were shorting out,, I wraped them with electric tape and the unit came on and stayed as for the thermostat make sure your flue is clear of all obstuctions even outside, make sure on the vent on the top back of the unit is clean and no lint or dust has built up on it, you can take a small soft brush and just sweep it across it

The indicator light stays on our PVS50 water heater.

You have the Robershaw wiper gas control valve.
Here are error codes and troubleshoot table for that gas control.
Here is general service manual for power vent water heaters.
Here is general parts list for that water heater, 2009:

Rheem model 41vrp40n flashes twice and stops working

Error code means that you have electronic gas control valve.

Copy following link to identify gas control valve, read error code meanings for each, and download service manual relevant to each gas control, but not specifically Rheem since rheem does not post service manuals.

The fact that water heater restarts, means that water heater is getting gas, getting sufficient air for combustion, thermister is ok, gas pressure is good, etc.
The fact that you unplug and replug water heater and it works, shows that you have power vent model.
Since water heater worked correctly before, 2 flashes with Rheem power vent model could mean that pressure switch has failed.

I too have an issue where our Rheem power vent water heater will not stay lit. I cannot see that it has a thermocouple though. I can only see the "glowplug" with two wires. The glow plug is fine....

You do not have thermocouple on your unit, you have a sensor. Rheem power vent water heaters ir very sensitive to any pressure changes. There are several things you can do to trouble shoot your water heater. Make sure the flue vent is fully open all the way out of the house. Unplug the unit from its electrical power source for 3 minutes, and then rest the heater. Make sure you have an adequate fuel supply, you may need to contact your local utility for a free inspection.

Rheem power vent motor doesn't shut off

There could be blockage in your water heaters venting on the outside of the home. It sound like the high limit switch has been tripped. Try unplugging the tank and plugging it back in. this will reset the tank. if the problem persists you will want to call your provider for service.

Rheem powervent ignites then goes out, electronic ignition.

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.
