How to Replace an Electric Water Heater Heating Element · Step 5 of 7
In this video
The access panel for the lower heating element is removed using a screwdriver. The insulation behind the panel is pulled back to expose the element's terminals and wiring. A multimeter is then used to test for any live voltage between the two terminals (line-to-line) and between each terminal and the ground screw (line-to-ground). The reading of zero volts confirms that the power is safely off. The two wires are then disconnected from the element by loosening the terminal screws.
Goal: Access the element and verify power is off
- Do not skip the step of testing for voltage with a multimeter, even if you are sure you flipped the correct breaker.

FAQs
What are the most critical safety precautions I must take when replacing a water heater heating element?
The most critical step is ensuring the power to the water heater is completely OFF at your home's main electrical panel or breaker box before touching any wires. Also, turn off the cold water supply valve to the heater. Safely draining the tank of hot water is also essential to prevent burns.
Is a special tool required for removing the heating element, or can I use a standard wrench?
While some might attempt it with a large socket or pipe wrench, a specialized heating element wrench (like the 'Rheem PROTECH Dual Head Element Wrench' mentioned) is highly recommended. This tool is designed to fit the element's hex head perfectly, minimizing the risk of stripping it and making removal and tightening much easier.
How long should I expect this project to take, especially considering the draining process?
The estimated time for this project is 3 hours, but beginners should budget closer to 4 hours. Draining the water heater tank can take anywhere from 30 minutes to over an hour, depending on your tank's size and the drainage rate. Don't rush the process, especially during safety-critical steps.
What's a common mistake beginners make during installation, and how can I prevent leaks around the new element?
A common mistake is not properly seating the new heating element's gasket or not tightening the element sufficiently. To prevent leaks, ensure the new gasket is clean and properly aligned on the element before insertion. Tighten the element firmly with your specialized wrench, but avoid over-tightening which can damage the tank or element.
