How to Test a Water Heater Element: A Complete Guide

Introduction

Welcome to this comprehensive guide on how to test a water heater element! A water heater is an essential home appliance that provides hot water for various purposes, including bathing, cooking, and cleaning. However, like any other appliance, your water heater may malfunction, and one of the most common issues is a faulty heating element. Testing your water heater element is crucial in diagnosing the problem and finding a suitable solution. In this article, we will guide you through the process of testing a water heater element step by step.

Before we dive into the details, it’s essential to understand how a water heater heats the water. A water heater consists of a tank filled with cold water, and two heating elements located at the top and bottom of the tank. When you turn on the heater, the upper element heats the water first, and when it reaches a certain temperature, the lower element takes over. This cycle continues until the water in the tank reaches the desired temperature.

Now, let’s get started and learn how to test a water heater element!

How to Test a Water Heater Element

Testing a water heater element is a simple process that you can do yourself. Here is a step-by-step guide:

Step 1: Safety First

Always make sure to turn off the power supply to the water heater and shut off the water supply to the tank before testing the element. This is crucial for your safety and to prevent any damage to the heater.

Step 2: Locate the Heating Element

The heating elements are usually located behind panels on the side of the water heater tank. You may need to use a screwdriver or pliers to remove the panels and access the elements.

Step 3: Check for Power

Use a voltage tester to check for power before touching any wires. If the tester shows a voltage reading, turn off the power supply to the water heater and try again. If there is still voltage, call an electrician to check the wiring.

Step 4: Test the Upper Element

Remove the wires from the upper heating element and test it using an ohm meter. Set the meter to the resistance setting and touch the meter leads to the element terminals. The reading should be between 10 and 20 ohms. If it’s outside this range, the element is faulty and needs to be replaced.

Step 5: Test the Lower Element

Repeat the same process for the lower heating element, but this time, remove the wires from the lower element and test it using the ohm meter. The reading should be between 10 and 20 ohms. If it’s outside this range, the element is faulty and needs to be replaced.

Step 6: Check for Continuity

If the reading on the ohm meter is zero or infinite, it means there is no continuity, and the element is faulty. A good element should have continuity, which means the circuit is complete and electricity can flow through it.

Step 7: Replace the Element

If you find that one or both of the elements are faulty, it’s time to replace them. You can do this yourself if you’re comfortable with the process, or you can call a professional plumber to do it for you.

Frequently Asked Questions

1. How often should I test my water heater element?

You should test your water heater element at least once a year to ensure it’s working correctly.

2. Can I test my water heater element myself?

Yes, you can test your water heater element yourself if you’re comfortable working with electricity and following safety protocols.

3. How do I know if my water heater element is faulty?

If your water heater isn’t producing enough hot water or the water isn’t heating up as quickly as it used to, it may be a sign that the heating element is faulty.

4. Can a faulty water heater element cause a fire?

Yes, a faulty water heater element can cause a fire if it overheats and ignites the insulation surrounding the tank.

5. How long does it take to test a water heater element?

Testing a water heater element usually takes about 30 minutes, depending on the accessibility of the heating elements.

6. How much does it cost to replace a water heater element?

The cost of replacing a water heater element depends on the type of heater and the level of damage to the element. On average, it costs between $150 and $300.

7. What should I do if I’m not comfortable testing my water heater element?

If you’re not comfortable testing your water heater element, you can call a professional plumber or electrician to do it for you.

8. Can I test my water heater element if the tank is full?

It’s not recommended to test your water heater element if the tank is full, as water and electricity don’t mix well. Drain the tank before testing the element.

9. Does testing a water heater element affect the warranty?

Testing a water heater element doesn’t affect the warranty, as long as you follow the manufacturer’s guidelines and safety protocols.

10. How can I tell if my water heater element is the problem?

If you’re experiencing a lack of hot water or slow heating, testing the water heater element is the first step in diagnosing the problem.

11. Can I test my water heater element without a voltage tester?

No, it’s essential to use a voltage tester to ensure there’s no power running to the water heater before testing the element.

12. What can I do to prevent my water heater element from failing?

You can prevent your water heater element from failing by maintaining it regularly, draining the tank periodically, and avoiding using harsh chemicals in the water.

13. Should I replace both heating elements at once?

If one heating element is faulty, it’s not necessary to replace both. However, it’s recommended to replace both elements if the heater is more than ten years old or if you have a history of problems with the elements.
