Check Elements (Continuity) — Testing the Heating Element (Electric Water Heaters)
Part of project
Troubleshooting No Hot Water: Fixing Your Water Heater · Step 3 of 3
In this video
To check the water heater elements, you can use continuity or an ohms test. For continuity, set the multimeter to the continuity setting. Disconnect the wires from the element. Touch the multimeter probes to both terminals on the element. A beep indicates a complete circuit, but this only confirms there is a path, not the quality of the element.
Goal: Verify Element continuity with multimeter
- Always disconnect power to the water heater before disconnecting any wires to ensure electrical safety.
- When disconnecting wires, take a photo or make a diagram to help with reassembly.

FAQs
Why is turning off both the power and water supply the very first step in troubleshooting?
This is crucial for your safety. Turning off the power prevents electric shock, while shutting off the water supply prevents scalding and potential flooding if a component needs to be removed or replaced. Always confirm both are off before touching any part of the water heater.
Do I absolutely need a multimeter like the Pro'sKit Digital Multimeter MT-1280 for this project?
Yes, a multimeter is essential for accurately testing the resistance of electric heating elements. Without it, you cannot reliably determine if an element is faulty, which is a key diagnostic step for electric water heaters. It helps avoid unnecessary part replacements.
How difficult is this water heater troubleshooting for a beginner, and is the 2-hour estimated time realistic?
This project is rated beginner-friendly because it focuses on clear, step-by-step diagnostics. The 2-hour estimate is realistic for diagnosing the problem, assuming no immediate parts replacement is needed. If a heating element needs to be replaced, it might take a bit longer.
What if my water heater is gas, not electric? Are these troubleshooting steps still applicable?
These specific steps, particularly testing heating elements, apply to electric water heaters only. Gas water heaters require different troubleshooting, typically focusing on the pilot light, thermocouple, or gas valve, and should not attempt electric element tests.
