FAILED ELEMENT TEST - AMPERAGE METHOD

Amperage Check: Measures the flow of current through a wire.

Failed Element Test – using “clamp type” Amperage Meter. Many multi-meters

could be used to conduct this test but be certain that possible amperage will not exceed

the multi-meter’s limit.

Complaint: No hot water. Check for proper voltage across ECO terminals 2 & 4. If

voltage is not detected press the red reset button to activate power and re-check.

Watts divided by volts = Amps Example: 4500W / 240V = 18.75 Amps

Conditions: Power on. Thermostat is calling for heat (water in tank is cold).

TEST: CLAMP METER AROUND EACH WIRE TO THE ELEMENT(S). IF THE WATER

HEATER HAS TWO ELEMENTS, THE TOP THERMOSTAT MUST BE SATISFIED BEFORE

POWER WILL BE SENT TO THE LOWER ELEMENT.

If Amperage is not detected the element must be replaced. (See also: Grounded

Element Check with Multi-meter) If partial amperage is noted, the element may be

grounded and must be replaced.
