Quick and easy: how to determine if your hot water heater element needs replacement

A faulty hot water heater element can leave you with cold showers and frustration. Fortunately, checking the element is a relatively simple task that you can do yourself. Here’s a comprehensive guide to help you determine if your hot water heater element needs replacing:

Signs of a Faulty Hot Water Heater Element

• No hot water: The most obvious sign of a faulty element is a lack of hot water.
• Cold water at the top of the tank: If the water at the top of the tank is cold while the bottom is hot, it indicates a problem with the element.
• Inconsistent water temperature: Fluctuating water temperatures can be a sign of a failing element.
• Buzzing or humming noises: As the element heats the water, it may produce a slight buzzing or humming sound. However, if the noise is excessive, it could indicate a problem.
• Rust or corrosion on the element: Over time, the element can become corroded or rusted, affecting its performance.

Tools and Materials You’ll Need

• Multimeter
• Screwdriver
• Wrench
• Gloves
• Safety glasses

Step-by-Step Instructions

1. Safety First: Before you begin, turn off the power to the hot water heater at the circuit breaker or fuse box.

2. Drain the Tank: To access the element, you need to drain the water from the tank. Turn off the cold water supply and open a hot water faucet to release the pressure. Then, attach a garden hose to the drain valve at the bottom of the tank and drain the water into a bucket or sink.

3. Remove the Access Panel: Locate the access panel on the side of the hot water heater and remove the screws holding it in place.

4. Disconnect the Element: Use a wrench to disconnect the wires connected to the element. Be careful not to touch any exposed wires.

5. Remove the Element: Use a screwdriver to unscrew the element from the tank. Be gentle to avoid damaging the threads.

6. Inspect the Element: Examine the element for any signs of corrosion, rust, or damage. If the element is visibly damaged, it needs to be replaced.

7. Test the Element with a Multimeter: To confirm if the element is faulty, use a multimeter to test its resistance. Set the multimeter to the ohms setting and touch the probes to the element’s terminals. A reading of infinity indicates a broken element.

8. Replace the Element: If the element is faulty, purchase a new one of the same size and wattage. Screw the new element into the tank and tighten it securely.

9. Reconnect the Element: Connect the wires to the new element and tighten the screws.

10. Refill the Tank: Close the drain valve and turn on the cold water supply. Open the hot water faucet to allow the tank to fill.

11. Restore Power: Turn on the power to the hot water heater at the circuit breaker or fuse box.

Resetting the Hot Water Heater

After replacing the element, you may need to reset the hot water heater. Locate the reset button on the side of the tank and press it. The heater will automatically start heating the water.

Troubleshooting Tips

• If you’re still not getting hot water after replacing the element, check the thermostat or the heating coils.
• If the element keeps burning out, it could be due to a problem with the wiring or the tank itself.
• If you’re not comfortable working on electrical appliances, call a qualified electrician for assistance.
