This post is where I expand on step 1 from my earlier post on how to fix a water heater.
You need a multimeter. You must be able to measure resistance somehow. I know, it’s futile. Just ignore the bellowing guard.
Here goes:
Check for a failed element
- Disconnect both wires from the heating element. Measure the resistance across the element (from one screw to the other). It should be a dozen ohms or so.
- Repeat for the other element.
- If either one is zero or a large number, that element is bad.

This is Alpha, the first-born, when he was 2YO.
This is Beta, the second-born, when he was about 2YO.
This is Gamma, the third-born, when he was about 18MO.
