How to Replace an Electric Water Heater Heating Element · Step 7 of 10
In this video
Before testing the heating element, it is crucial to ensure your safety. Locate the circuit breaker that controls the water heater and switch it to the 'off' position. After turning off the breaker, disconnect the power wires that are attached to the two screw terminals on the heating element. You cannot get an accurate reading with the wires still attached.
Goal: Safely prepare element for testing
- Always use a voltage tester to verify that there is no power going to the element before you touch any wires or terminals.
Used in this video
- Screwdriver (Screwdriver_Type: Phillips) — To loosen the screws on the terminals and remove the power wires.
- Voltage Tester (Voltage Tester: Non-contact) · optional — To confirm that the power to the water heater is completely off before starting work.

FAQs
What are the most critical safety steps I must take before replacing an electric water heater heating element?
Always start by turning off the power to your water heater at the circuit breaker and verifying it's off with a non-contact voltage tester. Next, shut off the cold water supply to the heater and drain the tank completely. Failing to do so can result in serious electrical shock or water damage.
Can I use a regular socket wrench to remove the heating element, or do I really need a specialized element wrench?
While a standard socket might fit, a specialized heating element wrench (like the Rheem PROTECH Dual Head Element Wrench listed) is highly recommended. It's designed for a snug fit, reducing the risk of stripping the element's hex head, which can make removal significantly more difficult.
The project is listed as 'beginner' and '4 hours' – is this realistic for someone with no plumbing experience?
Yes, it's beginner-friendly as long as you follow all safety procedures and instructions carefully. The 4-hour estimate accounts for the time-consuming process of fully draining and then refilling the water heater tank, along with potential delays like a stubborn element.
What's the most common mistake new DIYers make when replacing a heating element, and how can I prevent leaks?
A common mistake is not fully draining the tank or not properly seating the new element's O-ring/gasket. To prevent leaks, ensure the O-ring is perfectly positioned before tightening the new element firmly, but not excessively, and carefully monitor for drips after refilling.
