2) Press down on the reset button, also on the control panel. It should be marked, or it will have a red-colored cap. Hold this button down.
3) Reach into the opening and hold the match to the thermocouple pilot. You may need to keep the pilot light button depressed for up to a minute until the thermocouple warms and keeps the pilot lit.
Be careful with the match so as not to burn your fingers. If the pilot will not light or stay lit you may need to replace the thermocouple. Gas Water Heater Won’t Heat
