Element Test

OHMS Resistance Check**

Test Conditions:

This test uses the multimeter's battery as the electrical

supply.

Power to the water heater is "OFF".

Multimeter set to OHMS scale testing.

Black lead "Common" port.

Red lead in "Ω" or " OHMS" port.

Dial indicator set to scale above expected indication.

Note: Volts divided by amps = OHMS

Disconnect wires from the element terminals.

Test probe on each terminal of an element

See OHMS Resistance Table – Page 45

If … … then

proper resistance (+7.5%) is

present

continue testing.

meter reads "0"
