Why Does Water Heater Pilot Go Out?
A water heater pilot is a small flame that is used to ignite the burner in a water heater. It is an essential component of the water heater’s ignition system, and its purpose is to ensure that the burner ignites properly and maintains a consistent flame. However, like any other mechanical device, the pilot can malfunction and go out. But why does this happen? In this article, we will explore the common reasons why a water heater pilot goes out and what can be done to prevent or fix the issue.
Common Reasons Why a Water Heater Pilot Goes Out
There are several reasons why a water heater pilot might go out. Here are some of the most common causes:
- Dirty or Clogged Pilot Orifice: The pilot orifice is a small opening where the pilot flame emerges from the burner. If this opening becomes clogged or dirty, it can cause the pilot to go out. Regular cleaning and maintenance of the pilot orifice can help prevent this issue.
- Faulty Thermocouple: The thermocouple is a sensor that measures the temperature of the water heater and sends a signal to the pilot to keep the flame burning. If the thermocouple is faulty, it can prevent the pilot from staying lit. Replacing the thermocouple may be necessary in this case.
- Incorrect Pilot Settings: If the pilot is not adjusted correctly, it can cause the flame to go out. Consult the user manual or contact a professional to adjust the pilot settings.
- Leaks in the Water Heater: Leaks in the water heater can cause the pilot to go out. Check for leaks and repair them as soon as possible to prevent further damage.
- Low Water Pressure: Low water pressure can cause the pilot to go out. Check the water pressure and consider installing a water pressure booster pump if necessary.
- Malfunctioning Igniter: The igniter is responsible for igniting the pilot flame. If it is malfunctioning, it can prevent the pilot from staying lit. Replacing the igniter may be necessary in this case.
How to Prevent the Pilot from Going Out
Preventing the pilot from going out can save you from the hassle and expense of repairing or replacing it. Here are some tips to help you prevent pilot issues:
- Regular Maintenance: Regular maintenance can help prevent pilot issues. Check and clean the pilot orifice and thermocouple regularly, and adjust the pilot settings as needed.
- Check for Leaks: Regularly check for leaks in the water heater and repair them as soon as possible to prevent further damage.
- Monitor Water Pressure: Keep an eye on the water pressure and consider installing a water pressure booster pump if necessary.
- Avoid Overheating: Avoid overheating the water heater, as this can cause the pilot to go out. Check the thermostat and adjust it if necessary.
What to Do If the Pilot Goes Out
If the pilot goes out, it is essential to troubleshoot the issue and fix it as soon as possible to prevent further damage to the water heater. Here are some steps to follow:
- Turn Off the Power: Turn off the power to the water heater to prevent any further damage.
- Check the Pilot orifice: Check the pilot orifice for any blockages or debris. Clean or replace it if necessary.
- Check the Thermocouple: Check the thermocouple for any signs of damage or malfunction. Replace it if necessary.
- Adjust the Pilot Settings: Adjust the pilot settings as needed to ensure the pilot stays lit.
- Call a Professional: If you are not comfortable troubleshooting or repairing the issue yourself, call a professional to assist you.
Conclusion
In conclusion, a water heater pilot going out is a common issue that can be caused by a variety of factors. By understanding the common causes of this issue and taking steps to prevent it, you can ensure that your water heater remains in good working condition and continues to provide you with hot water. Remember to perform regular maintenance, check for leaks, monitor water pressure, and avoid overheating the water heater to prevent pilot issues. If the pilot does go out, troubleshoot the issue and fix it as soon as possible to prevent further damage.
