A malfunctioning electric water heater element can leave you with cold showers and a frustrating plumbing problem. But before you call in a professional, there’s a simple way to diagnose the issue yourself: testing the element.
This guide will walk you through the process of how to test electric water heater element, empowering you to troubleshoot the problem and potentially save money on repairs. We’ll cover everything from safety precautions to troubleshooting steps, making you a confident DIY plumber in no time.
Safety First: Essential Precautions
Before you start testing your electric water heater element, it’s crucial to prioritize safety.
- Turn off the power: The most important step is to disconnect the power supply to the water heater. Locate the circuit breaker controlling the water heater and switch it to the “off” position.
- Allow the water heater to cool: Hot water heaters can retain heat for a considerable amount of time. Allow the water heater to cool down completely before you start working on it.
- Wear protective gear: Always wear safety goggles and gloves to protect your eyes and hands from potential burns or electrical shocks.
Identifying the Element: A Visual Inspection
To test the element, you need to locate it first.
- Locate the water heater: Most electric water heaters are cylindrical tanks with two or more heating elements located at the bottom.
- Access the element: The elements are typically accessed through a removable access panel on the side of the tank.
- Visual inspection: Once you’ve located the element, give it a visual inspection. Look for any signs of damage, corrosion, or mineral buildup. These signs could indicate a faulty element.
The Tools You’ll Need
Testing an electric water heater element requires a few basic tools:
- Multimeter: A multimeter is essential for testing continuity and voltage.
- Screwdrivers: You’ll need screwdrivers to remove the access panel and disconnect the element wires.
- Safety glasses: Protect your eyes from potential sparks or debris.
- Gloves: Protect your hands from potential burns or electrical shocks.
The Testing Process: Step-by-Step
Now that you have the necessary tools and safety precautions in place, let’s test the element:
1. Disconnect the element: Carefully disconnect the wires leading to the element. Make sure you note the wire connections; you’ll need to reconnect them later.
2. Set the multimeter: Set your multimeter to the “ohms” setting. This will allow you to test the resistance of the element.
3. Connect the multimeter: Touch the probes of the multimeter to the element’s terminals. The probes should be connected to the metal parts of the terminals.
4. Read the resistance: A healthy element should have a resistance reading between 10 and 20 ohms. If the reading is zero or infinite, the element is likely faulty.
Troubleshooting Faulty Elements
If your element test reveals a faulty element, here’s what you need to know:
- Replace the element: If the element is faulty, it needs to be replaced. You can purchase a replacement element from most hardware stores or online retailers.
- Check the wiring: Before installing a new element, ensure that the wiring to the element is in good condition. Look for any signs of damage, corrosion, or loose connections.
- Professional assistance: If you’re not comfortable replacing the element yourself, it’s best to call a qualified electrician or plumber.
Beyond the Element: Other Potential Issues
While a faulty element is a common cause of hot water problems, other issues might be at play:
- Thermostat malfunction: A faulty thermostat might not be sending the correct signal to the element, preventing it from heating the water.
- Sediment buildup: Mineral buildup can insulate the element, reducing its efficiency and causing it to overheat.
- Wiring problems: Loose connections or damaged wiring can prevent the element from receiving power.
Your Water Heater’s Second Life: Maintenance Tips
Regular maintenance can prevent premature element failure and keep your water heater running smoothly:
- Flush the tank: Flush the tank annually to remove sediment buildup.
- Inspect the anode rod: The anode rod helps prevent corrosion. Inspect it regularly and replace it as needed.
- Check the pressure relief valve: The pressure relief valve releases excess pressure, preventing the tank from exploding. Test it regularly and replace it if it’s not functioning properly.
Final Thoughts: A Hot Water Hero
Testing an electric water heater element is a simple process that can save you time and money. By understanding the testing procedure and troubleshooting steps, you can confidently diagnose and address common water heater issues.
Remember, safety should always be your top priority. If you’re not comfortable with the process, don’t hesitate to call a qualified professional.
Basics You Wanted To Know
Q: How often should I test my electric water heater element?
A: While you don’t need to test the element regularly, it’s a good idea to check it if you experience any problems with your hot water supply.
Q: Can I use a voltage tester instead of a multimeter?
A: A voltage tester can only tell you if there is power going to the element. It cannot determine if the element itself is faulty.
Q: What should I do if I find my element is faulty?
A: If you find your element is faulty, you should replace it as soon as possible.
Q: What is the best way to prevent my element from failing in the future?
A: Regular maintenance, including flushing the tank and inspecting the anode rod, can help prevent premature element failure.
