Is your water heater’s pilot light constantly going out, leaving you with cold water? Understanding why this happens is crucial to ensuring your water heater operates efficiently. In Seattle, where chilly weather can exacerbate such issues, it’s important to know the potential causes. At Einstein Plumbing, we’re here to help you understand why your Seattle water heater’s pilot light keeps going out.

A pilot light that frequently goes out can be a frustrating issue, especially during the colder months. It can disrupt your daily routine and leave you without hot water when you need it most. However, by understanding the reasons behind this problem, you can take the necessary steps to address it. In this guide, we’ll explore common causes and solutions, helping you keep your water heater running smoothly throughout the year.

3 Main Reasons Why Your Water Heater Has Pilot Light Issues

When your Seattle water heater’s pilot light keeps going out, several factors could be at play. Here are three main causes to consider:

  1. Thermocouple Issues: The thermocouple is a safety device that detects if the pilot light is on. If it malfunctions, it may shut off the gas supply to the pilot light, causing it to go out. This could be due to a faulty thermocouple or a loose connection.

  2. Dirty Pilot Tube: A dirty pilot tube can cause the pilot light to flicker or go out. 

Dust, dirt, or debris can accumulate over time, blocking the flow of gas to the pilot light. Cleaning the pilot tube can often resolve this issue.

  1. Gas Supply Problems: Issues with the gas supply, such as low gas pressure or a faulty gas valve, can also cause the pilot light to go out. It’s essential to ensure that the gas valve is fully open and that there are no obstructions in the gas line.

It’s important to address these issues promptly to avoid further problems with your water heater. If you’re unsure how to troubleshoot or fix these problems, it’s best to contact a professional plumber for assistance.

Other Reasons Why Your Water Heater Has Pilot Light Issues

  1. Faulty Gas Valve: A faulty gas valve can prevent the proper flow of gas to the pilot light, leading to it going out. This can happen due to wear and tear over time or internal components malfunctioning. Replacing the gas valve is typically the solution, as it restores the proper gas flow and ensures the pilot light stays lit.

  2. Thermostat Issues: Problems with the thermostat can cause the pilot light to go out intermittently or fail to ignite. If the thermostat is not functioning correctly, it may not signal the gas valve to stay open, leading to the pilot light going out. Replacing or repairing the thermostat can resolve this issue.

  3. Drafts: Drafts near the water heater can disrupt the flame of the pilot light, causing it to go out. Ensuring that the area around the water heater is draft-free can help prevent this issue. Installing a draft hood or ensuring proper ventilation can also help mitigate the impact of drafts.

  4. Dirty Burner: A dirty burner can cause the pilot light to go out due to blockages that prevent proper ignition. Dirt and debris can accumulate on the burner, disrupting the flame. Regular cleaning and maintenance of the burner can prevent this issue, ensuring the pilot light stays lit.

  5. Flame Sensor Issues: The flame sensor is responsible for detecting the presence of the pilot light. If the flame sensor is faulty or dirty, it may not detect the pilot light, causing the gas valve to close and the pilot light to go out. Cleaning or replacing the flame sensor can resolve this issue.

  6. High Gas Pressure: Excessive gas pressure can cause the pilot light to go out. Ensuring that the gas pressure is within the recommended range can prevent this issue. Installing a pressure regulator can help regulate the gas pressure and prevent fluctuations that could lead to the pilot light going out.

  7. Improper Ventilation: Poor ventilation can cause the pilot light to go out due to incomplete combustion. If the area around the water heater is not properly ventilated, it can lead to a buildup of gases that disrupt the flame. Ensuring proper ventilation around the water heater can prevent this issue.

  8. Thermal Couple Issues: The thermal couple is a safety device that detects whether the pilot light is on. If the thermal couple is faulty or misaligned, it may shut off the gas supply to the pilot light, causing it to go out. Replacing or realigning the thermal couple can resolve this issue.

  9. Gas Supply Issues: Problems with the gas supply, such as low gas pressure or a gas leak, can cause the pilot light to go out. Ensuring that the gas supply is uninterrupted and that there are no leaks can prevent this issue. Regular inspection of the gas supply line and connections can help identify and resolve any issues.

FAQs on The Causes of Pilot Light Issues in Your Water Heater

Why does my Seattle water heater’s pilot light keep going out? Several factors can cause your water heater’s pilot light to go out frequently. It could be due to a faulty thermocouple, which is responsible for detecting the pilot light’s presence and shutting off the gas supply if it’s not lit. Another common issue is a dirty or clogged pilot light, which can prevent it from staying lit. Insufficient gas supply or a draft in the area where your water heater is located can also cause the pilot light to go out.

How can I fix a pilot light that keeps going out? Fixing a pilot light that keeps going out depends on the cause. If the thermocouple is faulty, it may need to be replaced. Cleaning the pilot light and the surrounding area to remove any dirt or debris can help if the issue is related to a dirty or clogged pilot light. Checking for drafts and ensuring the gas supply is sufficient are also important steps. If you’re unsure how to fix the issue, it’s best to contact a professional plumber for assistance.

Is it safe to relight the pilot light on my water heater myself? Relighting the pilot light on your water heater can be done safely if you follow the manufacturer’s instructions carefully. However, if you’re unsure or uncomfortable with the process, it’s always best to contact a professional plumber to relight the pilot light for you. They can ensure that the pilot light is lit correctly and that there are no underlying issues causing it to go out.

How often should I have my water heater serviced to prevent the pilot light from going out? It’s recommended to have your water heater serviced annually to ensure it’s running efficiently and to catch any potential issues before they become major problems. During a service, a plumber can check the pilot light and other components of your water heater to ensure they’re in good working order. Regular maintenance can help prevent the pilot light from going out frequently and extend the life of your water heater.

Can a malfunctioning pilot light cause other issues with my water heater? Yes, a malfunctioning pilot light can cause other issues with your water heater. If the pilot light isn’t working properly, it can prevent your water heater from heating water efficiently or at all. This can lead to issues such as lukewarm or cold water, which can be inconvenient and uncomfortable. Additionally, a malfunctioning pilot light can put added strain on other components of your water heater, potentially leading to further damage if not addressed promptly.
