In that picture, the water heater is set to "on" and your water heater would be operating on Electric, if you are hooked up to shore power or the generator is running. Flipping the switch down, turns off the electric to the water heater. Since the gas is also turned off, your water heater would not be operating.
The ceiling light switch is on, and all the other switches are in the off position....including the water pump. Hope this helps.
