Element Test (Continuity Tester)

I. Preparing for the Test

1.Press the power button on the User Interface Module (UIM).

2.Turn off power to the water heater at the breaker or disconnect switch serving the water heater.

3.Verify there is no power at the incoming power connections to the water heater with an AC Volt meter.

4.Remove the cover panel(s), then move the insulation away from the element. Do not damage the insulation.

5.Remove the thermostat cover(s).

6.Disconnect the wires from the element terminals.

IIA. Testing for a Burned Out Element

1.Complete Preparing for the Test before you proceed.

2.Place one test probe on each of the element terminals.

3.If there is no continuity, replace the element

(p. 24). If there is continuity, proceed to Testing for a Grounded Element.

IIB. Testing for a Grounded Element

1.Complete Preparing for the Test before you proceed.

2.Check for continuity as follows:

A.Place a test probe on one of the element terminals and the other test probe on the element flange or tank shell. Ensure a good ground connection.

B.Repeat the test for the other element terminal.

C.If either test shows continuity, the element is

defective and should be replaced (p. 24).

D.Proceed to Completing the Test.

III.Completing the Test

1.Replace the element(s) if necessary (p. 24).

2.Reconnect the terminal wires.

3.Reinstall the thermostat cover(s), put the insulation back in place, then reinstall the cover panel(s).

4.Make sure that the tank is full of water before reconnecting power.

A.Open a hot water faucet.

B.Once water flows smoothly from the hot water side of the faucet, all air has been purged from the tank and it is safe to energize the elements.

C.Reconnect power to the water heater.
