how to check electric water heater element

In today's post, we will be discussing how to test a water heater element. A water heater is an essential appliance in many households, providing hot water for various purposes. However, over time, the heating element in a water heater may deteriorate or malfunction, resulting in inadequate hot water or none at all. Therefore, it is essential to learn how to test the heating element efficiently.

Testing a Water Heater Element

Before we begin with the testing process, it is crucial to ensure the safety of both yourself and your water heater. Make sure you follow all safety precautions and guidelines provided by the manufacturer.

Gather the Required Tools

Before you start testing, it is necessary to gather the following tools:

A multimeter
A screwdriver
An electrical tester

Step-by-Step Procedure

Follow these steps to test the heating element in your water heater:

Step 1: Turn Off Power Supply

Before working on any electrical appliance, it is essential to turn off its power supply. Locate the circuit breaker or fuse box and turn off the power to the water heater.

Step 2: Locate the Heating Element

The heating element is usually located behind a panel on the side of the water heater. Use a screwdriver to remove the panel and access the heating element.

Step 3: Test for Power

Using an electrical tester, check for power at the heating element. This step ensures that there is no electricity flowing to the heating element, eliminating any risks of electric shock during testing.

Step 4: Set Multimeter to Ohms

Set your multimeter to the ohms function. This setting allows you to measure the resistance of the heating element accurately.

Step 5: Remove Wires

Before testing the heating element, you must remove the wires connected to it. This step ensures accurate readings during testing. Using a screwdriver, carefully disconnect the wires from the heating element.

Step 6: Test the Heating Element

Place the multimeter probes onto the heating element terminals. The reading displayed on the multimeter will indicate the resistance of the heating element. A functioning heating element will typically have a reading between 10 and 20 ohms.

Step 7: Compare Readings

Compare the reading from the multimeter to the expected resistance range provided by the manufacturer. If the reading is within this range, the heating element is functionally proper. However, if the reading is significantly higher or lower, it indicates a faulty or worn-out heating element that needs replacement.

Step 8: Replace the Heating Element

If the heating element is defective, you will need to replace it with a new one. Ensure you purchase a heating element suitable for your water heater model and follow the manufacturer's instructions for proper installation.

Remember, water heater repairs can be dangerous if not performed correctly. It is always recommended to consult a professional plumber or electrician if you are unsure or uncomfortable conducting these tests yourself.

In conclusion

Testing a water heater element is a straightforward process that can help diagnose and resolve issues with your hot water supply. By following the step-by-step procedure outlined in this post, you can determine if your heating element is functioning correctly or needs replacement. Remember to prioritize safety and consult professionals if necessary.
