1.    Complete Preparing for the Test before you 

proceed.

2.  Measure the element’s resistance by placing a 

probe on each terminal.  (See graphic at right.) 

3.  Compare your result with the following:

A.  If the resistance is between 10 and 25 Ohms, 

the element is good.  Proceed to Completing 
the Test.

B.  If the meter shows no continuity, the element 

should be replaced (p. 24).  Proceed to 
Completing the Test. 

C.  If the meter measures more than 25 Ohms, 

proceed to Testing for a Grounded Element.   

1.    Complete Preparing for the Test before you 

proceed.

2.  Check for resistance as follows:

A.  Place a probe on one of the element terminals 

and the other probe on the element fl ange or 
tank shell. Ensure a good ground connection.

B.  Repeat the test for the other element terminal.

C.  If both tests show infi nite resistance, the 

element is not grounded.  If either test shows 
less than infi nite resistance, the element is 
defective and should be replaced (p. 24).

D. Proceed to 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 

A.  Open a hot water faucet.

B. Once water fl ows 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.

1.  Press the power button on the User Interface 

Module.

1.  Turn off power to the water heater at the breaker 

or disconnect switch serving the water heater.

2.  Verify there is no power at the incoming power 

connections to the water heater with an AC volt 
meter.

3.  Remove the cover panel(s), then move the 

insulation away from the element.  Do not 
damage the insulation.

4.  Remove the thermostat cover(s).

5.  Disconnect the wires from the element terminals.
