Why Pilot Light Goes Out on Water Heater?
A faulty pilot light on your water heater can be a real nuisance, leaving you with no hot water for baths, showers, and household chores. But don’t worry, we’ve got you covered. In this article, we’ll delve into the common reasons why the pilot light goes out on your water heater, and provide you with tips on how to troubleshoot and fix the issue.
Why Pilot Light Goes Out on Water Heater?
The pilot light is a small flame that ignites the main burner of your water heater, producing the heat needed to warm the water. However, like any other appliance, water heaters can develop issues that cause the pilot light to go out. Here are some common reasons why the pilot light goes out on your water heater:
• Faulty Thermocouple: The thermocouple is a crucial component that helps to ensure the pilot light stays lit. If it’s damaged or faulty, the pilot light may go out.
• Clogged Burner: Lint, sediment, and other debris can accumulate in the burner assembly, preventing the pilot light from staying lit.
• Low Gas Supply: If the gas supply line is clogged or malfunctioning, the pilot light may not receive the necessary gas to stay lit.
• Faulty Pressure Relief Valve: A malfunctioning pressure relief valve can cause the pilot light to go out due to changes in water pressure.
• Faulty Water Level: If the water level in the tank is too low, the pilot light may go out.
• Clogged Water Inlet: Debris, sediment, or mineral buildup can clog the water inlet, preventing the pilot light from staying lit.
Symptoms of a Pilot Light That’s Gone Out
Before we dive into the troubleshooting process, let’s take a look at some common symptoms of a pilot light that’s gone out:
• No Heat: The most obvious symptom is the lack of hot water.
• Odd Noises: If your water heater is making strange noises, such as clicking, whistling, or banging, it may be a sign that the pilot light has gone out.
• Unusual Flues: If the flues are not venting correctly, it can cause issues with the pilot light staying lit.
Troubleshooting and Fixing the Issue
Now that we’ve covered the common reasons why the pilot light goes out on your water heater, let’s move on to the troubleshooting and fixing process.
Step 1: Check the Pilot Light Assembly
Before you start troubleshooting, make sure the pilot light assembly is clear of any debris or sediment. Use a vacuum cleaner or a soft-bristled brush to gently clean the area.
Step 2: Check the Thermocouple
As mentioned earlier, a faulty thermocouple can cause the pilot light to go out. Check the thermocouple for any signs of damage or malfunction. If it’s damaged, you may need to replace it.
Step 3: Check the Gas Supply
Check the gas supply line for any blockages or leaks. If the line is clogged or malfunctioning, the pilot light may not receive the necessary gas to stay lit.
Step 4: Check the Water Level
Check the water level in the tank to ensure it’s at the correct level. If the level is too low, adjust the water level according to the manufacturer’s instructions.
Step 5: Check the Pressure Relief Valve
Check the pressure relief valve to ensure it’s functioning correctly. If it’s malfunctioning, adjust or replace it according to the manufacturer’s instructions.
Step 6: Check the Burner
Check the burner assembly for any signs of clogging or damage. If the burner is clogged, clean it according to the manufacturer’s instructions.
Step 7: Relight the Pilot Light
If you’ve checked and cleared all the issues above, you can try relighting the pilot light. Make sure to follow the manufacturer’s instructions for relighting the pilot light.
Conclusion
A pilot light that’s gone out on your water heater can be frustrating, but by following the troubleshooting and fixing process outlined above, you should be able to get your water heater up and running again. Remember to always follow the manufacturer’s instructions when troubleshooting and repairing your water heater, and if you’re not comfortable with DIY repairs, consider hiring a professional plumber.
