SERVICE PROCEDURE E32-I

Heating Element Testing

Testing For Open Or Burned Out Element.

Step 1. TURN OFF POWER TO WATER HEATER.

Step 2. Remove thermostat/element access cover(s) from front of water heater. Remove insulation and plastic cover from thermostat.

Step 3. Disconnect wires from heating element. Step 4. Set multi-meter to “ohms” setting.

Step 5. Touch probes of multi-meter to screw terminals of heating element

(see illustration 1).

Step 6. Reading should be 12.8 ohms (±6%) for a 240 volt, 4500 watt element, see table below:

Ohms = Volts2 Watts

WARNING

High voltage exposure. Be sure power is turned

OFF to water heater prior to performing this

procedure.

A reading outside the range using the formula above (±6%), indicates a bad element and the element must be replaced.

Testing For Heating Element Short Circuit To Ground.

Step 1. TURN OFF POWER TO WATER HEATER.

Step 2. Remove access cover(s) from front of water heater. Remove insulation and plastic cover from thermostat.

Step 3. Disconnect wires from heating element. Step 4. Set multi-meter to “ohms” setting.

Step 5. Touch one probe of multi-meter to either screw terminal of heating element and the other on the element flange (see illustration 2). There should be no reading on the ohm meter. Any reading indicates a grounded element and the element must be replaced. Repeat this step for the other screw terminal.
