Water heater elements replaced?

You replaced the elements, but you don't say if you replaced the tstats.
Get new upper and lower tstats with the exact same number and layout of screws (does not have to be same brand) and exchange the wires individually from the old to the new one at a time.
Can't go wrong.
Good Luck!

Your first mistake was replacing the elements before you checked them to see if they were even the original problem. You will compound the error if you replace the thermostats without check them also. Having 110/120 volts to ground tells you nothing about the heater operation, thermostats, or elements. First you have to check if the elements SHOULD be heating then check them to see if they ARE heating.

And, of course, the most important question - did you completely fill the tank with water before energizing the elements, letting the air out? If you didn't, you fried them.
