Welcome to our guide on how to test water heater element. Water heaters are an essential part of our daily lives, providing hot water for showers, washing dishes, and laundry. However, they can break down, and one of the most common problems is a malfunctioning heating element. Testing your water heater element can save you time and money in the long run, and this guide will provide you with everything you need to know.
Before diving into the details of how to test your water heater element, let’s first understand what it is and how it works. Water heater elements are responsible for heating the water inside the tank. They are usually made of metal and are located at the bottom and top of the tank. When the thermostat signals that the water temperature is too low, the heating element turns on, and the water is heated to the desired temperature.
Now that you have a basic understanding of how water heater elements work, let’s discuss why testing them is essential.
Why Testing Your Water Heater Element is Essential
Testing your water heater element is crucial for several reasons:
🟢 Save money: A malfunctioning water heater element can cause your energy bill to skyrocket. By testing your element, you can identify problems early and avoid costly repairs or replacements.
🟢 Save time: If your water heater element stops working, you will have to call a technician to fix it, which can take days. By testing it, you can identify the problem sooner and prevent downtime.
🟢 Optimize performance: A faulty element can reduce the efficiency of your water heater, making it harder to heat your water to the desired temperature. Testing it can help you ensure that your water heater is functioning at its best.
🟢 Extend lifespan: Regularly testing your water heater element can help you extend its lifespan, saving you money in the long run.
Now that you understand the importance of testing your water heater element, let’s dive into how to do it.
How to Test Water Heater Element
Step 1: Turn off the Power Supply
The first step is to turn off the power supply to your water heater. You can do this by turning off the circuit breaker or fuse that controls the heater.
Step 2: Turn Off the Water Supply
The next step is to turn off the water supply to your heater. You can do this by closing the valve that supplies water to your heater.
Step 3: Drain the Water Heater Tank
You will need to drain the water heater tank before testing the element. Connect a hose to the drain valve located at the bottom of the tank and let the water run out into a bucket or drain. Be careful, as the water will be hot!
Step 4: Remove the Cover Plate
Once the tank is empty, remove the cover plate from the element. This is usually located near the bottom of the tank.
Step 5: Disconnect the Wires from the Element
Before testing the element, you need to disconnect the wires connected to it. Take a photo or label the wires to ensure that you can reconnect them correctly later.
Step 6: Test the Element with a Multimeter
Set your multimeter to the resistance setting and touch the probes to the screws on the element. If the reading is between 10 and 20 ohms, the element is okay. If the reading is zero or infinite, the element needs to be replaced.
Step 7: Reconnect the Wires and Cover Plate
If the element is okay, reconnect the wires and cover plate. Remember to tighten the screws and ensure that the wires are correctly connected.
