Hello: Let’s eliminate assumptions and start over, just to be sure. Turn off power and unhook one wire from each element. Test using ohms times one thousand (or two thousand) between each screw on the element and ground. You should get no continuity. If there is ANY, the element is leaking to ground and needs to be replaced. Next set the meter to one ohm and test between screws, on the element. You should see the needle swing most of the way over, suggesting good continuity. This tells you the element is still intact. If the needle moves only a little or not at all in ohms times one setting, the element is burned out.
If both elements are good, check the dip tube next… or thermostats, but best to be sure about the electrical side of things first 😉
