This sounds like to me possibly the heating element on the water heater is burnt or shorted.

What I would do is disconnect the wiring to the heating element on the water heater and then see if the breaker blows, one side of the water heater will always have AC voltage even with the switch off, when the switch is turned on for the electric a relay allows the AC voltage to complete the circuit, if the element is shorted out it can certainly trip the breaker.

Sounds like you have a Dometic/Atwood if you have the dual switches. Sometimes when you inspect these elements you might find the wiring burned out on them as well.

Beyond that hard to say what is going on, everything on that breaker circuit would need to be isolated.
