Not sure about a fuse, but if the back of the water heater is accessible, put an multi-meter set to ac volts on the two terminals of the heating element. Should read 110 volts with the switch on.
If it does, than problem is probably the heating element. Turn the switch off, (better yet, unplug your coach from shore power), remove both wires, put the multi-meter set to ohms and check the continuity between the two terminals. Not sure what it should read, but what you are looking for is a direct open, ie; no continuity, or a burnt out element. If you read an open, than bad element, replace, attach wires, and you should be in business.
If no voltage at element, than problem is wiring, switch, or that circuit breaker or fuse that you are looking for!
P.S. it COULD also be the temperature sensor is bad, but less likely . . .
