If the water heater element is shorted, it will trip the pedestal breaker as soon as power is connected . You indicated that the power occasionally works.

Any time a pedestal breaker trios, I check both ends of my power cord and the breaker for heat. Hold you hand near each one to see if it is running hot. That is a sign of a bad connection at that point.


I actually use a handheld IR thermometer, since I carry it to check tire temperatures at each stop.

When the water heater shorts, it is no longer active and no electricity is flowing thru the element. Just like a blown fuse.
