[Carl n Susan]

Not exactly Jim. The red light in the rocker switch illuminates when the switch is turned on and 12V is flowing to the water heater (i.e. it is turned ON). The red LED just to the right of the rocker switch illuminates while the WH is trying to ignite the propane burner. Once the burner lights, the LED goes out. The WH will make three tries to light before giving up and leaving the LED lit.

If the rocker switch is not illuminated I would check for 12V current to it. If the rocker is lit and the LED is not, then the WH should be running. I am at a loss to explain what is wrong if it isn't working.
