Most of the problems with a Rheem gas water heater will be related to the FVIR lockout. With most models your first step should be to press the TCO thermal reset button which is located on the front of the combustion door.

A shop vac with a custom extension or even compressed air can be used to clean the flame arrestor screen (intake). In order to access the intake you will usually need to remove the combustion door.

If the thermocouple shows a good reading you may need to replace the gas valve and FV sensor.
