Unlock the secrets: why your water heater keeps breaking down and how to fix it
What To Know
- If the thermostat malfunctions, it may not accurately sense the water temperature or may fail to turn the heating element on or off at the correct time.
- Loose connections, faulty wiring, or a malfunctioning circuit breaker can disrupt the power supply to the water heater, leading to a loss of hot water.
- To flush the tank, turn off the water supply to the water heater, open a hot water faucet to release pressure, and then connect a hose to the drain valve at the bottom of the tank.
Water heaters are indispensable appliances in our homes, providing us with warm and comforting showers, baths, and dishwashing. However, when a water heater starts malfunctioning repeatedly, it can be a major inconvenience and cause frustration. If you’re constantly asking yourself, “Why does my water heater keep going out?”, this blog post will delve into the possible causes and offer solutions to help you restore hot water to your home.
Common Causes of Water Heater Failure
1. Sediment Buildup
Over time, sediment and debris from the water supply can accumulate at the bottom of the water heater tank. This buildup acts as an insulator, preventing the heating element from effectively transferring heat to the water. As a result, the water heater may struggle to maintain the desired temperature or may overheat and shut down prematurely.
2. Faulty Heating Element
The heating element is responsible for generating heat within the water heater tank. If the heating element becomes damaged or fails, it will no longer be able to heat the water adequately. This can lead to lukewarm water or even complete loss of hot water.
3. Thermostat Malfunction
The thermostat controls the temperature of the water heater. If the thermostat malfunctions, it may not accurately sense the water temperature or may fail to turn the heating element on or off at the correct time. This can lead to overheating, premature shutdown, or insufficient heating.
4. Pressure Relief Valve Failure
The pressure relief valve is a safety feature designed to release excess pressure from the water heater tank. If the pressure relief valve fails or becomes clogged, it can prevent the release of pressure, which can lead to a potentially dangerous explosion.
5. Leaking Tank
A leaking water heater tank can be a major problem. Leaks can occur due to corrosion, rust, or damage to the tank. A leaking tank can waste water, increase your energy bills, and eventually lead to the complete failure of the water heater.
6. Electrical Faults
Electrical faults can also cause water heater problems. Loose connections, faulty wiring, or a malfunctioning circuit breaker can disrupt the power supply to the water heater, leading to a loss of hot water.
7. Overheating
Overheating is a common cause of water heater failure. This can occur due to a faulty thermostat, a clogged heating element, or a buildup of sediment. Overheating can damage the water heater tank and its internal components, leading to premature failure.
Troubleshooting and Solutions
1. Flush the Water Heater Tank
Regularly flushing the water heater tank can help remove sediment buildup and prevent premature failure. To flush the tank, turn off the water supply to the water heater, open a hot water faucet to release pressure, and then connect a hose to the drain valve at the bottom of the tank. Open the drain valve and allow the water to drain until it runs clear.
2. Inspect and Replace the Heating Element
If you suspect a faulty heating element, turn off the power to the water heater and remove the access panel. Inspect the heating element for damage or corrosion. If the heating element is damaged, it will need to be replaced.
3. Check the Thermostat
To check the thermostat, turn off the power to the water heater and remove the access panel. Use a multimeter to test the continuity of the thermostat. If the thermostat is not working properly, it will need to be replaced.
4. Inspect the Pressure Relief Valve
Visually inspect the pressure relief valve for any signs of leakage or clogging. If the valve is leaking or clogged, it will need to be replaced.
5. Repair or Replace the Water Heater Tank
If the water heater tank is leaking, it may be possible to repair the leak with a sealant or epoxy. However, if the leak is severe or the tank is badly damaged, it will need to be replaced.
6. Check Electrical Connections
Loose or faulty electrical connections can disrupt the power supply to the water heater. Inspect all electrical connections and ensure they are tight and secure. If necessary, tighten any loose connections or replace damaged wires.
7. Reset the Circuit Breaker
If the water heater is not receiving power, check the circuit breaker panel. The circuit breaker for the water heater may have tripped due to an electrical fault or an overload. Reset the circuit breaker by flipping it to the “off” position and then back to the “on” position.
Why is My Water Heater Going Out So Often?
There are several factors that can contribute to frequent water heater failures, including:
- Hard water: Hard water contains high levels of minerals, which can form scale buildup inside the water heater tank and heating element. This buildup can reduce the efficiency of the water heater and lead to premature failure.
- Poor maintenance: Regular maintenance, such as flushing the water heater tank and inspecting the heating element, can help prevent problems and extend the life of the water heater.
- Overuse: Using the water heater excessively or for extended periods can put strain on the appliance and increase the risk of failure.
- Old age: Water heaters typically have a lifespan of 8-12 years. As the water heater ages, it becomes more susceptible to problems and may require more frequent repairs or replacement.
Final Thoughts
If your water heater keeps going out, it’s important to identify the underlying cause and take appropriate action to resolve the issue. By following the troubleshooting steps outlined in this blog post, you can help diagnose and fix common water heater problems. If the problem persists or if you’re uncomfortable performing repairs yourself, it’s best to contact a qualified plumber for professional assistance.
Remember, regular maintenance and timely repairs can help keep your water heater functioning properly and provide you with years of reliable hot water.
Frequently Discussed Topics
Q: Why does my water heater keep tripping the circuit breaker?
A: The circuit breaker may trip if the water heater is drawing too much power. This can be caused by a faulty heating element, a leaking tank, or a short circuit.
Q: How often should I flush my water heater tank?
A: It’s recommended to flush your water heater tank at least once a year to remove sediment buildup.
Q: Can I replace the heating element myself?
A: Yes, it’s possible to replace the heating element yourself if you have basic electrical knowledge and tools. However, if you’re uncomfortable doing so, it’s best to contact a plumber.
