how to test water heater element with multimeter

Are you wondering how to test your water heater element with a multimeter? Well, you’ve come to the right place! In this blog post, we’ll show you how to do just that. We’ll also provide some tips on troubleshooting your water heater if the element is not working properly. So without further ado, let’s get started!


A water heater element is a vital part of your home’s plumbing. It is responsible for heating up the water that flows through your pipes and into your faucets. Over time, these elements can corrode and break down, which can cause your water heater to stop working properly.

If you think that your water heater element may be failing, you can use a multimeter to test it. This device will allow you to measure the electrical resistance of the element and determine whether or not it is still functioning properly.

Here is a step-by-step guide on how to test a water heater element with a multimeter:

1) Shut off the power to your water heater. Before you do anything, you will need to shut off the power supply to your water heater. This will prevent you from electrocuting yourself when you are testing the element.

2) Remove the access panel. Once the power is shut off, you will need to remove the access panel from your water heater in order to get to the element. Be careful not to touch any of the wires inside of the panel as they may still be live.

3) Locate the element. Once you have removed the access panel, you should be able to see the element inside of thewater heater. It will be attached to two exposed wires.

4) Test for continuity. Using your multimeter, touch one of the probes to one of the terminals on theelement. Then touch the other probe to the other terminal on the element. If there is continuity betweenthe two terminals, then the element is still good and does not need to be replaced. However, if there isno continuity between the two terminals, then this means thatthe element is bad and needs to be replaced.

What You’ll Need

-A multimeter
-A non-contact voltage tester

Testing the Water Heater Element

If your water heater isn’t heating water properly, it may be due to a faulty element. You can test the element with a multimeter to see if it is functioning correctly.

1. Turn off the power to the water heater.
2. Disconnect the wires from the element.
3. Test for continuity with the multimeter. The meter should read zero ohms if the element is working properly.
4. If the meter reads infinite ohms, or there is no reading at all, the element is most likely faulty and will need to be replaced.


After testing the water heater element with a multimeter, it is concluded that the element is bad and needs to be replaced.
