How to Restart Hot Water Heater Pilot Light?
The pilot light is a crucial component of your hot water heater, responsible for igniting the burner that heats the water. When the pilot light goes out, it can leave you without hot water until it’s restarted. Don’t worry, restarting the pilot light is a relatively simple process. In this article, we’ll guide you through the steps to restart your hot water heater pilot light.
What is a Pilot Light?
Before we dive into the process of restarting the pilot light, let’s take a quick look at what it is. The pilot light is a small flame that is used to ignite the burner in your hot water heater. The burner is responsible for heating the water, and the pilot light is what ignites it. The pilot light is usually located at the bottom of the water heater and is typically about 1/4 inch in diameter.
Causes of Pilot Light Failure
Before we get into the steps to restart the pilot light, it’s important to understand why it might have gone out in the first place. Some common causes of pilot light failure include:
- Incorrect Gas Pressure: If the gas pressure is too low, the pilot light may not stay lit.
- Clogged or Dirty Burner: If the burner is clogged or dirty, it can prevent the pilot light from staying lit.
- Faulty Thermocouple: The thermocouple is a sensor that helps to maintain the pilot light. If it’s faulty, the pilot light may not stay lit.
- Drafty or Unstable Pilot Light: If the pilot light is too close to a drafty area or is not stable, it may not stay lit.
Step-by-Step Guide to Restarting the Pilot Light
Restarting the pilot light is a relatively simple process. Here’s a step-by-step guide to help you get started:

- 6 **Step 6: Adjust the Pilot Light**
- 7 **Step 7: Turn On the Gas Supply**
- 8 **Step 8: Check the Pilot Light**
**Step 1: Turn Off the Gas Supply**
The first step is to turn off the gas supply to the water heater. This is usually done by locating the gas shut-off valve and turning it clockwise. Make sure to turn it off completely to prevent any gas leaks.
**Step 2: Remove the Pilot Light Assembly**
Next, you’ll need to remove the pilot light assembly. This is usually done by unscrewing the pilot light assembly cap or by removing the screw that holds it in place. Be careful not to touch any of the electrical components while you’re doing this.
**Step 3: Clean the Pilot Light Assembly**
Once the pilot light assembly is removed, use a small brush or a toothbrush to clean out any debris or sediment that may be accumulated. Make sure to clean the area around the pilot light hole as well.
**Step 4: Check the Thermocouple**
Next, check the thermocouple to make sure it’s not faulty. The thermocouple is a sensor that helps to maintain the pilot light. If it’s faulty, you may need to replace it.
**Step 5: Light the Pilot Light**
Once the pilot light assembly is clean and the thermocouple is checked, you can light the pilot light. You can use a lighter or a match to light the pilot light. Hold the flame to the pilot light hole until it ignites.
**Step 6: Adjust the Pilot Light**
Once the pilot light is lit, you may need to adjust it to ensure it’s burning correctly. Make sure the flame is about 1/4 inch high and is centered over the pilot light hole.
**Step 7: Turn On the Gas Supply**
Once the pilot light is adjusted, you can turn on the gas supply. Make sure to turn it on slowly to prevent any gas leaks.
**Step 8: Check the Pilot Light**
Finally, check the pilot light to make sure it’s staying lit. If it’s not, you may need to adjust it again or check for any leaks in the gas supply.
Troubleshooting Tips
If you’re having trouble restarting the pilot light, here are some troubleshooting tips to help you:
- Check the gas pressure: Make sure the gas pressure is at the correct level. If it’s too low, the pilot light may not stay lit.
- Check the burner: Make sure the burner is clean and free of debris. If it’s clogged, it can prevent the pilot light from staying lit.
- Check the thermocouple: Make sure the thermocouple is not faulty. If it’s faulty, you may need to replace it.
- Check for drafts: Make sure the pilot light is not too close to a drafty area. If it is, it may not stay lit.
Conclusion
Restarting the pilot light on your hot water heater is a relatively simple process. By following the steps outlined above, you should be able to get your hot water heater up and running again. Remember to always turn off the gas supply before attempting to restart the pilot light, and to check for any leaks in the gas supply after you’re finished. With a little practice, you should be able to restart the pilot light like a pro.
