33 Performing an Ohms Test on the Heating Element
1. Perform the steps in “Shutting Down the Water
Heater” on page 32.
2. Set your multi-meter to the Ohms resistance setting.
3. Locate the relay access cover and remove.
I
If you do not see a relay access cover, the relay is at
the rear of the Water Heater and the element is in a
plastic box at the rear of the Water Heater.
4. Disconnect the two wires going to the heating
element from the relay.
5. Attach the leads to the terminals of the heating
element. The reading should be between 9–11Ohms.
I
Consult the operating manual for your multi-meter
for specific device function.
If the readings fall outside of the specification, it
indicates a faulty heating element.
