@chanda you checked teh wiring going to your hot water heater? You checked the fuses to those lines? What is your household voltage 110V (North America) or 220/240 (Europe)? What make is your HW heater?

Check the wires running power from the top element to the bottom one. They sometimes burn out.

Be sure to check the reset button/limit switch located above or near the upper element.

I use this webpage to test my water heater:

New thermostats, new bottom element. Wiring checks out okay. 110 v to the lower red wired line but no voltage to the black wired line.

If each element is on a separate thermostat the one connected to that element may be bad or the element itself may be.

That's what we thought, and we changed all that to new, but with no luck.

@jrbryant so you have a water heater where the bottom element is not working? You checked the power? What make and model is our water heater? What else have you checked?

It's an AO Smith electric water heater, 40 gal I think. Less than 10 years old, no deposits found in tank, no corrosion on elements. Power checks okay, top element 220v. Lower element shows no voltage.

John Bryant, You really should have posted this as a new question, instead of a comment in an answer a year old to get answered by more ifixit volunteers. On a duel element residential water heater, both elements do not heat at the same time. The link below may be able to answer you issue.
