How to Light the Pilot on Your Water Heater: A Step-by-Step Guide

Lighting the pilot light on your water heater may seem intimidating at first, but with the right guidance, it can be a simple and safe process. Whether you're dealing with a sudden loss of hot water or you're doing routine maintenance, this guide will help you get your water heater up and running. Follow these practical steps, and you'll have hot water flowing in no time.

Safety First: What You Need to Know

Before attempting to light the pilot:

• Ensure Safety:
  • Turn off the gas supply to prevent any accidental leaks.
  • Make sure the area is well-ventilated to avoid the accumulation of gas.
• Gather Necessary Tools:
  • Long lighter or matchstick
  • Flashlight

Finding the Pilot Light Assembly

Identify Your Water Heater Type

Water heaters generally fall into two categories: older models with a manual ignition and newer models with a piezo igniter.

• Older Models: Require using a matchstick or lighter to ignite the pilot.
• Newer Models: Have a button to ignite the pilot, making the process more straightforward.

Step-by-Step Pilot Lighting Instructions

Step 1: Locate the Gas Control Valve

The gas control valve is usually located on the outside of the water heater. It's typically labeled and easy to find.

Step 2: Turn the Control Knob

• Turn the knob to the "Off" position and wait for 5 minutes. This ensures any built-up gas dissipates.

Step 3: Access the Pilot Light

• Identify and expose the access panel to reach the pilot light assembly. This may involve removing a small cover.

Step 4: Light the Pilot

• For Older Models:

  • Turn the control knob to "Pilot."
  • Hold down the reset or pilot button.
  • Using a lighter or matchstick, bring the flame to the opening where the pilot is located while holding down the button.
  • Once lit, keep holding the button for 30 seconds to ensure the flame remains stable.

• For Newer Models:

  • Turn the control knob to "Pilot."
  • Push and hold the pilot button.
  • Press the igniter button. You may need to press it several times until the pilot ignites.
  • Hold the pilot button for 30 seconds after ignition.

Step 5: Confirm the Pilot is Lit

Visually confirm that the pilot is lit. The flame should be steady and blue. If it’s not lit, repeat the process ensuring you're following the exact steps.

Step 6: Turn the Gas Control Knob to "On"

After confirming the pilot is lit and stable, turn the gas control knob to the "On" position. This will allow the water heater to start heating water again.

Troubleshooting Tips

• Pilot Won't Stay Lit:

  • Ensure you're holding the pilot button for at least 30 seconds after ignition.
  • Check if the thermocouple is functioning. It might need cleaning or replacement.

• No Ignition Spark (Piezo Igniter):

  • Ensure the igniter wiring is intact.
  • The igniter might need a replacement if no clicking sound is heard upon pressing.

When to Call a Professional

If you've followed these steps and are still having trouble, it might be time to call a professional. Issues could indicate a faulty thermocouple, a clogged pilot orifice, or a more complex problem requiring expert handling.

Taking the time to light your water heater's pilot correctly can save you from unnecessary frustration and expenses. With this guide, you should feel confident in handling the task safely and efficiently. Enjoy your revitalized hot water supply!
