problem with electric water heater-Fixed but new problem

I do think it must the heating element. It is under an extended warranty. So they can fix it at no cost to me.
Also, I did check the bypass valve. It was not leaking. The gas comes on when I throw the switch, and heats up the water nice and hot.

By the way, I appreciate the video submitted by bob on how to take off the heating element. It is real easy and the guy who made the video aught to be commended.
