Water Heater Repair, Part 2

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.
