AO Smith Water Heater Vapor Sensor

I have a GPVL 40 200 gas hot water tank. I'm not getting hot water and the code "7" is blinking which means the Flammable Vapor Sensor Lockout is activated. A couple of questions, is there a reset, or is there a natural gas leak or is the sensor malfunctioning. The unit is 5 years old.

Thanks Rick
