How to Light the Hot Water Heater Pilot Light?

Water Heater Pilot Light

The water heater pilot light is a tiny flame that has an immense impact on the water heater’s functioning. Despite its importance, it’s common for pilot lights to go out unexpectedly. You may ask, why do pilot lights go out on water heaters? There are various reasons, including the gradual buildup of dirt or debris that snuffs out the flame, a faulty thermocouple or gas valve that fails to keep the pilot light ignited, a storm of wind,  and a momentary disruption in the gas supply.

Regardless of the cause, the water heater pilot light going out signifies that homeowners must take immediate action. This blog will discuss how to light a hot water heater pilot light if it goes out.

How To Light A Hot Water Heater Pilot Light?

Here are the steps to safely light the pilot light on a water heater:

Turn Off Gas Supply:

Locate the gas valve on your water heater and turn it to the “off” position. This ensures that no gas flows while you work on relighting the pilot light.

Access the Pilot Light:

Remove your water heater’s access panel or cover to expose the pilot light assembly. This panel is usually located near the bottom of the water heater.

Locate Pilot Light Assembly:

You’ll see the assembly once the panel is removed. It typically consists of a small gas valve, a thermocouple, and the pilot light.

Find Pilot Light Control Knob:

Locate the control knob near the pilot light assembly. It should have settings for “off,” “pilot,” and “on.”

Set Knob to Pilot Position:

Turn the control knob to the “pilot” position. Hold the knob in this position to allow gas to flow to the pilot light.

Press and Hold Down Knob:

While holding the control knob in the “pilot” position, locate the ignition button or spark igniter. Press and hold it down to ignite the pilot light.

Observe Pilot Light:

Continue holding down the control knob for about 30 seconds after the pilot light ignites. This allows the thermocouple to heat up and establish a stable flame.

Release Control Knob:

After about 30 seconds, release the control knob. The pilot light should remain lit. If it doesn’t, repeat the process, ensuring that you’re holding the knob down long enough to allow the thermocouple to heat up.

Set Control Knob to On:

Once the pilot light is lit and stable, turn the control knob to the “on” position. This allows gas to flow to the main burner, heating the water in the tank.

Replace Access Panel:

Once the pilot light is lit and the control knob is set to the “on” position, replace the access panel or cover on your water heater.

Turn On Gas Supply:

Finally, turn the gas supply back on at the main valve. This restores gas flow to the water heater, allowing it to heat water as needed.

Verify Operation:

Test the hot water faucets in your home to ensure that hot water is flowing correctly. If everything is functioning as it should, it means, you’ve successfully lit the pilot light on the water heater.

Following these steps carefully is crucial to ensuring that the pilot light is lit safely and securely without any potential hazards. If you face any difficulties or the pilot light refuses to stay lit, it may be a sign of a more significant problem. You can contact Spot-On’s professional plumber for assistance.
