Find and remove the metal panel(s) attached to the side of your water heater. During testing, make sure that the water in the tank is not above the lukewarm level. Here are the steps to follow when using a digital multimeter to check the resistance in the heater elements.

Or set your multimeter on ohm testing or diodes testing. Remove the cover plates to get to the element ends and the thermostats. A dial usually does this on the tool;

If your meter doesnt show any reading then you. Remove the upper access panel screws first on the electric water heater with a screwdriver. Remove the insulation and disconnect the electrical wire at the terminal and use your multimeter to test the electrical flow.

How to find your water heater elements: Locate the hot water heaters circuit breaker in your electrical panel and turn it off. Now let us get started with the following steps on how to test a water heater with multimeter.

If the multimeter registers any reading then your element is working properly. Water heater elements have a relatively short lifespan. Switch off the breaker supplying power to the water heater.

If it is, you will have a reading of 240v on terminals 1 and 3. Measuring continuity of an electric water heater using a digital multimeter. Below are the steps to follow:

The multimeter should read at or near zero. To use the multimeter and test your water heater element, you will need to set the multimeter to the lowest setting for ohms resistance. But if there is no reading, check its power source.

Open the water tap, and let the water flow till its cold. Locate the hot water heaters circuit breaker in your electrical panel and turn it off. A good element should have a resistance of between 10 and 16 ohms.

An electric water heater has two elements, an upper and a lower. Use a vom, dmm, or ohmmeter or multimeter set to read resistance or ohms as follows: Now remove the water heater element form the water heater thermostat and then set your multi meter knob on connectivity testing.

Locate and remove one or two panels on the side of the water heater. There may be some insulation that needs to be pushed back out of the way. Now touch one of the screws of the heating element to one of the probes and touch the other screw with the other probe.

Remove the plastic safety cover from the element face exposing the screw terminals.
