In this guide, we’ll explore 12 signs that your Seattle water heater’s pilot light is acting up.

3 Main Signs Your Water Heater Has Pilot Light Issues

Flickering Pilot Light: A flickering pilot light can be caused by various issues, such as a dirty pilot tube, a faulty thermocouple, or a gas supply problem. If the pilot light is dirty or obstructed, it may not be able to stay lit consistently. A faulty thermocouple, which senses the pilot light’s heat and controls the gas valve, can also lead to intermittent operation. Additionally, a problem with the gas supply, such as low pressure or a blockage, can cause the pilot light to flicker or go out. If you notice your pilot light flickering, it’s essential to have a professional inspect and repair the issue to ensure safe and efficient operation of your water heater.

Weak or Yellow Flame: A weak or yellow flame in your water heater’s pilot light can indicate a combustion problem. The pilot light should have a strong, blue flame, indicating that the gas is burning efficiently. A weak or yellow flame could be caused by a dirty or clogged pilot orifice, which can disrupt the proper mixture of gas and air. This can lead to incomplete combustion, producing carbon monoxide, a colorless and odorless gas that can be dangerous if not vented properly.

If you notice a weak or yellow flame, it’s crucial to have a professional plumber inspect and clean the pilot assembly to ensure safe operation of your water heater.

Difficulty Igniting: Difficulty igniting the pilot light, or it taking multiple attempts to stay lit, can be indicative of several issues. It could be due to a problem with the ignition system, such as a faulty igniter or pilot control valve. It could also be due to a dirty or damaged thermocouple, which can prevent the pilot light from staying lit once ignited. Additionally, a gas supply problem, such as low pressure or a blockage, can cause issues with ignition. If you experience difficulty igniting your pilot light, it’s important to have a professional plumber diagnose and repair the problem to prevent further issues with your water heater.

Other Signs Your Water Heater Has Pilot Light Issues

Unusual Odors: If you notice unusual odors coming from your water heater, especially a rotten egg smell, it could indicate a gas leak. A malfunctioning pilot light can lead to gas leaks, which can be hazardous. If you detect any strange odors near your water heater, it’s important to turn off the gas supply immediately and contact a professional plumber.

Pilot Light Goes Out Frequently: A pilot light that goes out frequently is a clear sign of a problem. This could be due to issues with the thermocouple, a dirty pilot orifice, or a malfunctioning gas control valve. If your pilot light keeps going out, it’s essential to have a professional inspect and repair the issue to prevent further problems.

Soot Buildup: Excessive soot buildup around the pilot light or burner area can indicate a combustion problem. This can be caused by a dirty or clogged burner, improper air-to-fuel ratio, or other issues. Soot buildup can affect the efficiency of your water heater and should be addressed promptly by a professional.

Water Heater Not Providing Enough Hot Water: If your water heater is not providing enough hot water or the water temperature fluctuates, it could be a sign of a pilot light issue. A malfunctioning pilot light can lead to inconsistent heating, resulting in inadequate hot water supply. If you experience this issue, have a professional plumber inspect your water heater.

Water Heater Making Strange Noises: Unusual noises coming from your water heater, such as popping, banging, or rumbling sounds, can indicate sediment buildup or other issues affecting the pilot light. Sediment buildup can insulate the water from the heat source, leading to overheating and potentially damaging the tank. If you hear strange noises from your water heater, have it checked by a professional.

Visible Damage to Pilot Light Assembly: If you notice visible damage to the pilot light assembly, such as corrosion, rust, or physical damage, it’s a clear sign that something is wrong. Damaged components can lead to improper functioning of the pilot light and should be repaired or replaced by a professional plumber.

Fluctuating Flame: A pilot light flame that flickers or fluctuates in size can indicate a problem with the gas supply or combustion. This could be caused by a dirty or clogged pilot orifice, improper air-to-fuel ratio, or other issues. If you notice a fluctuating flame, have a professional inspect your water heater.

Pilot Light Flame Not Reaching Thermocouple: The pilot light flame should be directed towards the thermocouple. If the flame does not reach the thermocouple or is weak, it may not be able to heat the thermocouple properly, leading to issues with the gas control valve. If you notice this issue, have a professional plumber inspect your water heater.

Visible Water Leaks: If you notice water leaks around your water heater, it could be a sign of a pilot light problem. Water leaks can be caused by a variety of issues, including a faulty temperature and pressure relief valve or a damaged tank. If you see any signs of water leaks, have your water heater inspected by a professional plumber.
