Understanding Pilot Light Issues in Water Heaters
If you’re dealing with a water heater pilot light that won’t stay lit, you’re not alone. This common issue can disrupt your hot water supply and cause inconvenience for your household. Understanding why your water heater pilot light won’t stay lit is the first step to solving the problem efficiently. At Flow Pro Plumbing, we provide expert water heater repair services in Brentwood, CA, and surrounding areas including Byron, Antioch, Bay Point, Bethel Island, and Oakley.
Common Reasons Your Water Heater Pilot Light Won’t Stay Lit
Several factors can cause the pilot light to fail repeatedly:
- Dirty or Clogged Pilot Tube: Dust and debris can block the pilot tube, preventing the flame from staying steady.
- Faulty Thermocouple: This safety device detects the flame and signals the gas valve to stay open. A worn or defective thermocouple can shut off gas flow, causing the pilot light to go out.
- Gas Supply Issues: Low gas pressure or interrupted supply can extinguish the pilot light.
- Drafts or Airflow Problems: Strong drafts near the water heater can blow out the pilot flame.
- Faulty Gas Control Valve: If the valve malfunctions, it may not supply gas properly to keep the pilot light lit.
Why Fixing Your Pilot Light Matters
A water heater pilot light that won’t stay lit means your water heater won’t produce hot water reliably. This can lead to discomfort, increased energy bills, and even potential safety hazards like gas leaks.

FAQs
What to do when the water heater pilot light won’t stay lit?
If your water heater pilot light won’t stay lit, it could be due to a faulty thermocouple, dirty pilot tube, or issues with the gas supply. First, try checking for debris or dirt that might be blocking the pilot light orifice. Sometimes, the pilot light sensor may also fail, causing it to shut off automatically. If basic troubleshooting doesn’t fix the problem, it’s best to have a professional plumber inspect your water heater for gas leaks or faulty components.
Why does my pilot light go out as soon as I release the pilot button?
A pilot light that goes out immediately after releasing the pilot button usually indicates a malfunctioning thermocouple. The thermocouple detects whether the pilot light is lit and signals the gas valve to stay open. If it’s dirty, damaged, or misaligned, it can’t sense the flame properly, shutting off the gas supply. Other possible causes include a weak gas flow or a faulty gas control valve.
How to clean a thermocouple on a water heater?
Cleaning a thermocouple involves turning off the gas supply, removing the thermocouple, and gently wiping it with fine sandpaper or steel wool to remove corrosion and soot buildup. This can help restore proper heat sensing function. However, if the thermocouple is severely damaged or worn out, replacement is recommended for safety and optimal water heater performance.
Why won’t my pilot light stay lit even with a new thermocouple?
If the pilot light still won’t stay lit after replacing the thermocouple, the issue might be related to the gas valve, pilot assembly, or a clogged pilot orifice. Additionally, insufficient gas pressure or airflow problems can cause the pilot to go out. A licensed plumber can diagnose these more complex issues using specialized equipment to ensure your water heater operates safely and efficiently.
How do I know if my thermocouple is bad on my water heater?
Signs of a bad thermocouple include the pilot light frequently going out, the water heater not heating properly, or the smell of gas near the appliance. A simple test involves using a multimeter to check the thermocouple’s voltage output. If the readings are below manufacturer specifications, the thermocouple likely needs replacement to prevent gas flow interruptions and maintain safe operation.
