Before disconnecting anything, visually inspect the element for any obvious signs of damage such as corrosion, cracks, or mineral buildup. Heavy mineral buildup can also hinder the element’s performance.
4. Performing the Electric Water Heater Element Test
With the element exposed and the power completely off, it’s time to use your multimeter.
4.1 Setting the Multimeter
Set your multimeter to the ohms (Ω) setting. Select a range that’s appropriate for the expected resistance of your electric water heater element. Consult your water heater’s manual; most home elements should show a reading between 10 and 20 ohms. A reading outside of this range suggests a potential problem.
4.2 Measuring the Resistance
Carefully disconnect the wires from the element terminals. using your multimeter, touch the probes to each terminal. The multimeter will display the resistance in ohms.
4.3 Interpreting the Results
- Low Resistance (Close to Zero): This indicates a short circuit, meaning the element is faulty and needs replacement.
- Infinite Resistance (OL): This indicates an open circuit, signifying a broken element that also requires replacement.
- Resistance within the Normal Range (10-20 ohms typically): This suggests the element is functioning correctly. Note: this range can vary depending on the model, so check your manual for the specific range for your element.
5. Troubleshooting: Beyond the Element
Even if the element tests good, there could be other issues causing your hot water problems. Consider these:
- Thermal Cut-off Switch: This safety device shuts off power if the water gets too hot. Test its continuity with your multimeter.
- Thermostat: A faulty thermostat won’t send power to the heating element. Testing this requires more advanced knowledge and may be better left to a professional.
- Sediment Buildup: Mineral deposits can insulate the element, reducing efficiency. Flushing the tank might resolve the issue.
- Insufficient Power Supply: Check that the breaker is the correct amperage for your water heater.
6. Replacing the Electric Water Heater Element (If Necessary)
If your electric water heater element testing reveals a faulty element, replacing it is often a straightforward DIY repair.
6.1 Sourcing a Replacement Element
Find a replacement element that matches the specifications of your current element. You can find these online (e.g., Amazon, Home Depot) or at a local plumbing supply store.
6.2 Installation
Follow the manufacturer’s instructions carefully when installing the new element. Ensure a proper seal to prevent leaks.
7. When to Call a Professional
While testing an electric water heater element is a manageable DIY task, some situations warrant professional help:
- Extensive Electrical Knowledge is Lacking: If you are uncomfortable working with electricity, it’s best to call a professional.
- Complex Issues: If the problem extends beyond a simple element replacement (multiple issues), a licensed plumber or electrician should assess the situation.
- Safety Concerns: Never hesitate to call a professional if you have any safety concerns during the testing or repair process.
