There is the breaker, the power switch, the high limit switch, the thermostat, the heating element in the circuit.  Any one of these items can be bad.  With the power off and disconnected from the Casita you can check continuity using a multimeter on the ohms setting all the way to the heating element and you will measure a short from the breaker.  The heater element is 1440 watts so the resistance across the heating element on a good one is around 10 ohms. There is a reset button on the hi-limit switch that may be tripped too.  If power was applied to the hot water tank that had no water in it then the heating element is probably bad and will measure infinite ohms with a multimeter...Hope this helps!!

Under that black rubber cover on the outside of the water heater, there are not only those two reset buttons, but if you remove the black rubber cover, (WITH THE TRAILER UNPLUGGED!) you can check the fusible links that live under that rubber cover as well.  Bear in mind, if you remove that rubber cover, there are some exposed 120 VAC electrical components behind it, so make sure the trailer is unplugged, but you need to visually and electrically check them to tell if they are intact or have blown. They sometimes blow, (fuse,) and would need to be checked out to see if they have opened. If they have, then they would need to be replaced. Just one more thing on your check list to troubleshoot.
