That's what happened. Two wires went to the wrong place. Thanks for the help. After I read your reply, I checked my wiring again.

How can an element show 0 ohms? Infinite ohms, sure. But 0? What am I missing?

once an element burns out, its like a cut wire, it will show no ohms or no resistance...

When an element burns out the ohms will be extremely high, not zero.

only if the burned out coil makes contact with the outer shell of the heating element, otherwise its like holding the 2 leads on the ohm meter 2 inches apart and not touching, there is no reading because the coil is broken in 2...if you had a 3 ft piece of copper and you had the ohm meter on both ends you would read continuity on the ohm meter, now have someone cut the wire in half, no more reading..thats what happens when the coil wire burns out and breaks in the heating element..

How to Determine Which Water Heater Element Is Bad?

by Robert Korpella Turning on the faucets for a relaxing shower only to find tepid or icy water makes for a frustrating experience. When an electric hot water heater’s elements short out or burn through, cool water is the result. Typically, the lower element goes first, but that’s not always the case. Fortunately, a few quick electrical tests reveal which element you must replace in order to restore hot water to your home.




1

Turn off the power to the electric hot water heater. Some units are wired to plug into a wall socket, and power is shut off simply by unplugging them. Most units are hard wired directly into the home’s circuitry, so turn the breaker for the hot water heater to “OFF” at the home’s main electrical panel.

2

Remove the two wires connected to the water heater element and push them aside. Unscrew the mounting hardware with a screwdriver, slip the wires out and bend them out of your way.

3

Set the multitester to measure ohms, or resistance. The ohm key is typically written in green and identified with an omega sign on the tester. Set the scale to the lowest readings, usually “RX1K” or “RX1.”

4

Touch a probe on the multitester to each screw on the element. If you get no reading, or a maximum reading, the element is bad. Elements do have some resistance, so a reading of 10-16 ohms is normal, with higher ohm readings for 3,500 watt elements and lower readings for 5,500 watt elements. The wattage of your element is printed on the plastic block between the two screws where the wires were attached.

5

Touch one probe to a screw on the element and the other probe to bare metal on the water heater. Any ohm reading or slight movement of the multitester’s needle indicates an element that has shorted out. Check each screw on both elements.

6

Touch one probe to the element screw and the other to the metal frame of the element (but not to the other screw). Any needle movement or reading indicates an element that has shorted out. Check each screw on both elements in the same manner.

Maximum reading would be the infinite as Toli said or open line as my ohm meter reads

So in a residential service call for 'no hot water', do you guys replace just {1} element?

And if one of the t-stats is determined to be bad, same question. Do you just replace {1} t-stat?
