How to Start a Pilot Light on a Water Heater
Introduction: A pilot light is a small flame that ignites the main burner of a water heater to produce hot water. Without a functioning pilot light, your water heater may not work properly, resulting in cold showers and laundry woes. In this article, we will guide you on how to start a pilot light on a water heater.
How to Start a Pilot Light on a Water Heater?
Before you begin, make sure you have taken the necessary safety precautions. Turn off the main gas supply and let the water heater cool down if it has been running for a while. Wear gloves and safety goggles to protect yourself from burns and debris.

Step 1: Locate the Pilot Light and Controls
- Find the pilot light assembly, usually located on the side or top of the water heater.
- Identify the pilot light button, reset button, and igniter.
- Make a note of the type of pilot light control system your water heater has. Common types include electric ignition, manual ignition, and piezo ignition.
Step 2: Prepare the Pilot Light for Ignition
- Check the pilot light orifice for blockages and clean it if necessary. You can use a toothpick or a small brush to remove any debris.
- Check the thermocouple for proper positioning and secure it if loose.
- Verify that the pilot light button is in the "pilot" position. If your water heater has an electric ignition, this may not apply.
Step 3: Light the Pilot Light
- Hold a long, flame-resistant lighter or matches near the pilot light opening.
- Light the pilot light and keep the flame steady until it ignites the thermocouple.
- Once the pilot light is lit, release the igniter and let it settle for a few seconds.
- Check the pilot light to ensure it remains lit.
Step 4: Reset the Pilot Light Control
- Press the pilot light button to reset the pilot light control.
- Hold the button for 10-15 seconds to ensure the control is reset correctly.
- Verify the pilot light is still lit and the thermocouple is still functional.
Common Problems and Solutions
- Pilot light won’t light:
- Check for blockages in the pilot light orifice.
- Verify the thermocouple is properly positioned and secure.
- Ensure the pilot light button is in the correct position.
- Pilot light keeps going out:
- Check for a blocked thermocouple or improper positioning.
- Ensure the pilot light button is in the correct position.
- Verify the orifice is clean and clear of debris.
- Main burner won’t light:
- Ensure the pilot light is lit and functioning correctly.
- Check for blockages in the burner orifice.
- Verify the thermostat is set correctly.
Prevention is the Best Medicine
To prevent future pilot light issues, perform regular maintenance on your water heater. Clean the pilot light orifice regularly to prevent blockages. Check the thermocouple periodically to ensure proper positioning. Replace the pilot light and thermocouple every 5-10 years or as recommended by the manufacturer.
Table: Pilot Light Maintenance Schedule
| Task | Frequency |
|---|---|
| Clean pilot light orifice | Every 3-6 months |
| Check thermocouple positioning | Every 6 months |
| Replace pilot light and thermocouple | Every 5-10 years |
By following these steps and performing regular maintenance, you can ensure your pilot light remains functional and your water heater runs smoothly. Remember to always turn off the main gas supply and let the water heater cool down before attempting to start the pilot light. Happy DIY-ing!
