Do you have a Ohm meter?
Your checks should be between power lead and neutral, then Power lead to ground, and ground to neutral.
Get those real quick, I will see what mine are and at least we can get a comparison for you.
Now, in my experience, I hate GFI's, and have chased more then my fair share of problems just to find out the GFI was at fault.
Sorry, Welcome to FTE!!!!

Between hot and neutral is what you should be most concerned with, Neutral and ground/ground and hot, you want nothing.
I would suggest inspection of your cable, but yes, sounds like the heater is shot.

No problem!!
Now if you would, go out and do you ohm checks with a new heater, this will give you a reference latter on down the line.. Sort of a Predictive Maintenance thing.
