Have you opened the outside door to the hot water heater? There should be an on/off switch in that area. This is for electric use. If you have a gas option on it, that switch should be inside.
MAKE SURE THE TANK IS FULL WHEN YOU HIT THE ON SWITCH. If you turn the water heater on when empty, you will burn out the element. Always turn it off when done camping, just in case.
Also, when you winterize at the end of the season, make sure you release the pressure relief valve or you will get a nice shower.
