Homeowners often face the challenge of a malfunctioning water heater, but many are unaware that the solution can be a simple replacement heating element. The Efficiency Maine Trust, known for promoting energy conservation, emphasizes that a properly functioning heating element is crucial for optimal water heater performance and energy savings. A multimeter, a common tool in any plumber’s toolkit, is essential for diagnosing a faulty element before initiating any repairs. Selecting the correct replacement heating element for your Rheem or Kenmore water heater model ensures compatibility and efficient heating.
Replacing Your Water Heater Element: A Comprehensive DIY Guide
Replacing a faulty water heater element is a common homeowner task that, with the right guidance and a bit of confidence, you can tackle yourself. This guide will walk you through the process, focusing on safely and effectively replacing the replacement heating element.
1. Safety First: Preparation is Key
Before you even think about touching your water heater, safety needs to be your top priority. Mishandling electricity and hot water can be extremely dangerous.
- Turn off the Power: Locate the circuit breaker that controls your water heater and switch it off. Double-check that the power is indeed off using a non-contact voltage tester on the wires at the water heater. Don’t skip this!
- Turn off the Water Supply: Find the cold water inlet valve on top of the water heater and close it completely. This prevents more water from entering the tank while you’re working.
- Allow the Water to Cool: This is crucial. scalding water can cause serious injuries. Wait several hours, or even overnight, for the water in the tank to cool down.
-
Gather Your Tools & Materials: Having everything ready will streamline the process. You’ll need:
- New replacement heating element (make sure it’s the correct voltage and wattage for your water heater – check the existing element or your water heater’s manual).
- Element wrench (specifically designed for water heater elements).
- Multi-meter (for testing continuity and voltage).
- Screwdrivers (Phillips and flathead).
- Pliers.
- Bucket and hose.
- Towel or rags.
- Non-contact voltage tester.
2. Draining the Water Heater
Draining the water heater is necessary to access the replacement heating element.
- Attach a Hose: Connect a garden hose to the drain valve located near the bottom of the water heater.
- Position the Hose: Run the other end of the hose to a safe drainage point, such as a floor drain, outside, or a large sink. Be mindful of the volume of water that will be released.
- Open the Drain Valve: Slowly open the drain valve.
- Vent the Tank: To help the water drain faster, open a hot water faucet somewhere in your house. This allows air to enter the tank and prevents a vacuum from forming.
- Drain Completely (Almost): Drain the tank until the water level is below the replacement heating element you’ll be replacing. You don’t need to drain the entire tank, just enough to safely remove the element.
3. Accessing and Removing the Old Element
Now that the water is drained, you can get to the faulty element.
- Remove the Access Panel: Locate the access panel covering the element. Use a screwdriver to remove the screws holding it in place.
- Remove the Insulation: Carefully pull back the insulation behind the panel. You may need to peel back any tape holding it in place.
- Disconnect the Wires: Use pliers to disconnect the wires from the terminals of the replacement heating element. Note the position of each wire before disconnecting them; you’ll need to reconnect them in the same way.
- Remove the Element: This is where the element wrench comes in. Fit the wrench onto the element and turn it counterclockwise to loosen it. It might be tight, so apply steady pressure. Once loosened, unscrew the element completely by hand.
- Inspect the Old Element: Examine the removed element. Signs of damage, such as corrosion, mineral buildup, or a broken coil, indicate the element was faulty.
4. Installing the New Replacement Heating Element
With the old element removed, it’s time to install the new one.
| Step | Description |
|---|---|
| 1 | Prepare the New Element: Apply Teflon tape to the threads of the new element. |
| 2 | Insert the Element: Screw the new element into the tank by hand, turning it clockwise until it’s snug. |
| 3 | Tighten with Wrench: Use the element wrench to tighten the element securely. Don’t overtighten, but ensure it’s firmly in place to prevent leaks. |
| 4 | Reconnect the Wires: Reconnect the wires to the element terminals exactly as they were connected to the old element. Double-check your notes or photos. |
| 5 | Replace Insulation and Access Panel: Put the insulation back in place and reattach the access panel. |
5. Refilling and Testing the Water Heater
Almost there! Now, refill the tank and test your work.
- Close the Drain Valve: Make sure the drain valve is tightly closed.
- Open the Cold Water Inlet Valve: Slowly open the cold water inlet valve to refill the tank.
- Bleed the Air: Open a hot water faucet somewhere in the house to allow air to escape from the tank as it fills.
- Check for Leaks: Carefully inspect the replacement heating element for any leaks. If you see any, tighten the element slightly.
- Turn on the Power: Once the tank is full and you’ve checked for leaks, turn the circuit breaker back on.
- Test for Hot Water: Wait a few hours for the water to heat up. Then, test the hot water at a faucet. If the water heats up properly, you’ve successfully replaced the element! If not, retrace your steps to ensure everything is connected correctly.
This whole process revolves around properly installing a new replacement heating element, so make sure you’ve selected the right one for your system.
FAQs: Replace Water Heater Element
How do I know if my water heater element is bad?
Common signs include lukewarm water, no hot water at all, or a circuit breaker that trips frequently when the water heater is on. These issues can often indicate a failing or faulty replacement heating element.
What safety precautions should I take before starting?
Turn off the power to the water heater at the breaker box. Then, shut off the cold water supply valve to the tank. Always test the wiring with a non-contact voltage tester to ensure the power is truly off before touching any electrical connections.
What tools will I need for this replacement?
You’ll typically need a multimeter, a water heater element wrench (or socket), screwdrivers, pliers, a bucket, and a non-contact voltage tester. Having some rags handy is also a good idea. Ensure you have a new replacement heating element of the correct voltage and wattage.
Can I replace only one element if my water heater has two?
Yes, you can. However, it’s often recommended to replace both elements at the same time. This ensures consistent performance and prevents you from having to repeat the process soon after if the other replacement heating element fails.
So, there you have it! Replacing a water heater element might seem daunting, but with a little patience and this guide, you’ve got this. Remember to always prioritize safety and if you’re ever unsure, calling in a professional is the best bet. Now, go forth and conquer that faulty replacement heating element, and enjoy that hot shower!
