Blows the fuse or trips out an AC breaker? On LP gas mode or AC electric mode? Make and model of your water heater would be helpful here.

That usually indicates that the heating element is burned out. Check that with an ohm meter.

trips is 660 watts. Wouldn't the thermal fuse blow first?

No thermal fuse on the AC portion.

What about the heating element? I think you may find it is burned out. Ohm it out and see.
