    Are you sure you have power to the unit?
    Are you sure you have plenty of water flowing through the heater?

    Looks like there are three(3) hi temp switches (one with manual reset), two(2) limit switches, and a water pressure switch (to ensure flow) that will hold it out. I'd try resetting the manual hi temp reset after you make sure there's plenty of water flow.
