Check the following:
See if your heater has a pilot gas adjustment valve. It should be on the gas control valve somewhere. Not all heaters have these. It will be a screw on the valve that can be turned.
Make sure the thermocouple sensing bulb is squarely in the pilot flame and also check that the fitting where the other end of the thermocouple connects to the main gas valve is tight.
Check the pilot gas orifice (where the pilot gas comes out) for carbon build up - you may need to remove the pilot gas line and thermocouple assembly to get to this. This problem is pretty common.
Check the gas pressure to the heater. Run the hot water in the dwelling until the hot water heater starts. Check the flame on the main burner and see what color it is - it should be blue with possibly some yellow-tipped flames. If not, there could be a problem with the gas pressure at the heater or venting. If the heater has a gas pressure regulator, it may be out of adjustment or defective.
Finally, and this isn't very common, the pilot light can be extinguished if there is a draft problem, usually associated with an issue with the flue pipe venting system for the heater or another nearby gas consuming appliance.

SOURCE: need reset code for richmond
I am poting this here hopefully it will help someone else. I have a richmond 40 gallon power vent water heater and it was not working. It was flashing 2-3 on the LED. I used this procedure and it started up..
you can reset the control by unplugging the blower during start up, leave unplugged for at least 5 seconds, plug back in and within 30 seconds cycle temp control from hot to low 6 times.
