Imagine turning on the shower after a long day only to find the water cold. If this happens, it might mean there’s a problem with your water heater.
One of the most common issues is a burned-out heating element. But how can you tell if the element has burned out? Here’s a simple guide to help you check and fix a faulty water heater element.

How Does a Water Heater Element Work?
An electric water heater uses a heating element to heats up the water by converting electricity into heat. As electricity flows through the element’s insulator, resistance creates heat that heats up the surrounding water.
Modern heating elements come in three main types:
- Metal Elements: Made from nickel and chrome alloys with high resistance for effective heating.
- PTC Elements: Use ceramic discs to control heat and reduce fire risks safely.
- Composite Elements: Combine metals and ceramics for balanced performance.
These elements endure high heat but can burn out over time, stopping them from heating the water effectively. Most water heaters have two elements, one at the top and one at the bottom, that can develop different issues based on their position.
Overheating can result from sediment buildup, thermostat malfunctions, or worn heating elements. NOTE: Regular water heater maintenance can help avoid these problems and keep your water heater running efficiently.
Common Signs Your Water Heater Element Is Burned Out
Recognizing the signs of a burned-out water heating element is the first step in fixing the problem. Here are common symptoms to watch for:
- Fluctuating Water Temperature
The heating element may fail if the water suddenly shifts from hot to cold or only reaches lukewarm temperatures, regardless of the thermostat setting.
- Hot Water Runs Out Quickly
Running out of hot water faster than usual can indicate a problem. A working element keeps the water hot consistently, while a faulty one cannot maintain the temperature.
- No Hot Water at All
If there’s no hot water, the element might be completely burned out, leaving the water cold.
- Unusual Noises
Hissing, crackling, or popping sounds can mean mineral buildup around the element, making it less effective and more likely to fail.
- Circuit Breaker Keeps Tripping
If the water heater frequently trips the circuit breaker, it may signal that the element has a short-circuited.
If you notice any of these issues, test your water heater element to see if it needs replacement.
Testing Your Water Heater Element
If you’ve noticed signs of a burned-out water heater element, the next step is to test it. This process is straightforward and only requires a multimeter and basic caution.
- Safety first
Turn off the water heater power at the circuit breaker. Never skip this step, water and electricity can be dangerous.
- Locate the Elements
Most home water heaters have two heating elements, one near the top and one at the bottom. These are behind access panels on the heater’s side. Remove the panels and insulation to reach the elements.
- Testing the Element
Set your multimeter to the lowest setting for ohms resistance. Place one probe on one element’s terminals and the other on the second.
- If the multimeter shows a reading above zero, the element is working.
- If there’s no reading, the element is burned out and should be replaced.
Testing your water heater element can confirm if it’s the source of the problem.
Steps to Replace a Water Heater Element
- Safety first
Turn off the power at the main electrical panel. Use a non-contact tester to ensure no power is running to the element.
Shut off the water heater’s circuit breaker. Let the water cool, and then check a hot water tap to confirm.
Remove the heater’s access panel, fold back the insulation, and use a circuit tester. If there is no power, remove the screws and disconnect the wires.
Use a multimeter. A reading of 0 means it needs replacing; any reading suggests the other element may be the issue.
Turn off the cold water supply. Attach a garden hose to the drain valve and drain the water until it’s below the element.
Use a wrench to turn the element counterclockwise. For a flange type, remove screws and gasket, then pull out the element.
Clean the tank’s gasket area, attach the new element, and secure it.
Close the drain, open the water inlet, and let the water run through a nearby faucet for a few minutes.
Secure wires to the terminals, reassemble the cover, turn on the power, and test.

The Importance of Regular water heater Maintenance
While replacing a burned-out water heater element can solve an immediate problem, regular maintenance helps prevent issues from starting. Consistent care, keeps your water heater efficient and extends its lifespan. Many issues with heating elements come from mineral buildup, especially in hard water areas. Over time, sediment collects around the component, making heating less effective and increasing burnout risks.
Flushing your water heater once a year helps clear out sediment. It’s a simple but often overlooked task that involves draining the tank to remove minerals and inspecting heating elements for wear. A yearly check-up with one of our professional technician can further prevent issues, ensuring all parts are in good shape.
