My Rheem tankless water heater model RTG-95DV will not ignite, my remote gives a error code 11. I checked the gas valve it is opened all the way, I can also hear the igniter clicking. Looking at the circuit board there is a LED light it will start flashing when I try to start the heater it continues to flash after the heater is shut down, what is this light for?
