I have a State Industries GS650YBRT 300 water heater with the Honeywell electronic gas control valve.
This hot water heater will not light.
I am able to get the pilot light to light and after a short delay, the indicator light on the control valve LED status light begins to flash normally.
At this point, the pilot button should be able to be released and the pilot light remains lit in order to select an operating temperature on the control knob. However, as soon as the pilot button is released, the pilot light extinguishes, regardless of how long it is held in after the pilot light initially ignites.
Obviously the system is sensing the pilot light being lit in order to cause the control valve LED status light to flash. The status light flashes once every 3 or 4 seconds and does not indicate any faults, so why will the pilot light not remain lit?
