How To Check Your Hot Water Heater Element In 5 Easy Steps!
What To Know
- The heating element in a hot water heater is responsible for transferring electricity into heat, which warms the water.
- A leaking element can cause water to drip from the bottom of the hot water heater.
- Set the multimeter to the ohms range and touch the probes to the terminals on the element.
Hot water heaters are an essential part of our daily lives, providing us with warm showers, comfortable baths, and clean dishes. However, when the water heater element fails, it can be a major inconvenience. This blog post will provide a step-by-step guide on how to check a hot water heater element, empowering you to diagnose and fix the issue yourself.
Understanding the Hot Water Heater Element
The heating element in a hot water heater is responsible for transferring electricity into heat, which warms the water. Over time, the element can become corroded or burnt out, leading to reduced water temperature or complete failure.
Signs of a Faulty Hot Water Heater Element
- Lukewarm or cold water: The most common sign of a faulty element is a decrease in water temperature.
- No hot water: If there is no hot water at all, the element may have burnt out completely.
- Leaking water: A leaking element can cause water to drip from the bottom of the hot water heater.
- Buzzing or humming noises: A faulty element may produce unusual noises when the heater is turned on.
Safety Precautions
Before checking the hot water heater element, it is crucial to take the following safety precautions:
- Turn off the power: Shut off the electricity to the water heater at the breaker box.
- Turn off the gas: If you have a gas water heater, turn off the gas supply valve.
- Drain the water: Allow the water to cool completely and then drain it from the tank using the drain valve.
How to Check a Hot Water Heater Element
1. Remove the Access Panel
Locate the access panel on the side or bottom of the hot water heater. Remove the panel using a screwdriver or wrench.
2. Disconnect the Wires
Carefully disconnect the wires connected to the heating element. Note the position of the wires for reassembly.
3. Remove the Element
Unscrew the nuts or bolts holding the heating element in place and pull it out of the tank.
4. Inspect the Element
Examine the element for any signs of corrosion, burn marks, or breaks. If the element is visibly damaged, it needs to be replaced.
5. Test the Element with a Multimeter
If the element does not show any visible damage, use a multimeter to test its continuity. Set the multimeter to the ohms range and touch the probes to the terminals on the element. A reading of zero or close to zero indicates continuity, while an infinite reading indicates a break in the element.
6. Replace the Element
If the element is faulty, replace it with a new one of the same wattage and size. Tighten the nuts or bolts securely and reconnect the wires.
7. Reassemble the Water Heater
Reinstall the access panel and turn on the power and gas (if applicable). Open a hot water faucet to allow air to escape from the lines.
Troubleshooting Common Issues
- No continuity in the element: Replace the element.
- Continuity in the element but no hot water: Check the thermostat, wiring, or other components.
- Water leaking from the element: Replace the element and ensure the seal is tight.
- Element burns out quickly: Check for sediment buildup in the tank, which can cause the element to overheat.
Wrap-Up: Maintaining a Healthy Hot Water Heater
By following these steps, you can effectively check and replace a hot water heater element, ensuring a reliable supply of hot water for your home. Regular maintenance, including periodic inspections and sediment removal, can help extend the life of your water heater and prevent future problems.
