A common issue with gas geysers, especially in Pakistan, is the pilot light going out. This can happen due to gas load shedding or a temporary interruption in the gas supply. Relighting the pilot can be done in different ways, depending on whether your water heater has an igniter, an electronic pilot, or requires manual lighting. Here’s a step-by-step guide covering various methods to help you get your geyser up and running again.
How to Relight a Pilot Light on a Water Heater with an Igniter
If your gas geyser has an igniter, relighting the pilot is relatively straightforward:
- Turn off the gas: Switch the gas valve to the “Off” position and wait for about 5 minutes to clear any remaining gas.
- Turn the valve to “Pilot”: Once the gas has cleared, turn the valve to the “Pilot” position.
- Press the igniter: While holding down the pilot button, press the igniter button (usually a red or black button) a few times until you hear a clicking sound and see the pilot light ignite.
- Hold for a few seconds: Keep holding the pilot button for about 30 seconds to ensure the pilot light stays lit.
- Switch to “On”: After the pilot light stays lit, turn the gas valve back to the “On” position.
How to Light a Gas Water Heater with an Electronic Pilot
Newer models of water heaters may have an electronic pilot system that automatically lights the pilot. Here’s how to activate it:
- Turn off the gas: Always start by switching off the gas valve and waiting for 5 minutes.
- Turn the thermostat to the lowest setting: Make sure the thermostat is turned all the way down.
- Switch to “Pilot” mode: Set the gas control knob to the “Pilot” position.
- Activate the electronic igniter: Press and hold the pilot button, then press the electronic ignition button (often labeled “Ignite” or similar). This should automatically light the pilot.
- Wait: Continue holding the button for about 30 seconds to make sure the pilot stays on.
- Set the thermostat: After the pilot is lit, set your thermostat to the desired temperature and switch the gas valve to “On.”
How to Reset the Water Heater Pilot Light
Sometimes the pilot light may need resetting. This is a quick fix when the pilot is on but isn’t heating the water effectively:
- Turn off the water heater: Switch the gas valve to “Off” and wait for 5-10 minutes.
- Turn to “Pilot” mode: Move the gas valve to the “Pilot” position.
- Press the reset button: Many gas water heaters have a reset button near the valve. Press and hold this button while attempting to light the pilot.
- Light the pilot: Use either the igniter or manual lighting method to relight the pilot.
- Switch to “On”: Once the pilot stays lit, turn the gas valve back to “On” and adjust the temperature setting.
How to Turn On a Water Heater Pilot Light
If your pilot light has gone out and you need to turn it back on, follow these general steps:
- Turn the gas off: Set the gas control valve to “Off” and allow gas to dissipate for about 5 minutes.
- Turn to “Pilot”: Move the valve to the “Pilot” position.
- Ignite the pilot: Depending on your model, either press the igniter button or light the pilot manually.
- Hold the button: Keep the pilot button pressed for at least 30 seconds to ensure the flame stays on.
- Turn to “On”: Once the pilot is stable, switch the valve to the “On” position.
How to Light a Pilot Light on a Gas Heater Manually
If your geyser doesn’t have an igniter, you can light the pilot manually with a match or lighter:
- Turn off the gas: Switch the gas valve to “Off” and wait for 5 minutes to clear out any gas.
- Locate the pilot: Find the pilot light opening, usually under the water heater.
- Turn the valve to “Pilot”: Move the gas control knob to “Pilot.”
- Light the pilot: Use a long lighter or match to reach the pilot and ignite it while holding down the pilot button.
- Hold the button: Keep pressing the pilot button for 30 seconds until the flame remains lit.
- Turn the gas to “On”: Once the pilot is steady, turn the valve to the “On” position.
What to Do if the Water Heater Pilot Won’t Light
If you’ve tried the above steps and the pilot light still won’t ignite, check the following:
- Gas supply: Ensure that your gas supply is working and the gas valve is open.
- Thermocouple: The thermocouple might be faulty, preventing the pilot from staying lit. You may need a professional to replace it.
- Air in gas line: If you recently installed the geyser or had repairs done, air could be trapped in the gas line, preventing ignition. You’ll need to keep trying to light the pilot until the air clears.
Water Heater Pilot Light Replacement
If your pilot light assembly is damaged or worn out, it might need replacing. Here’s how to proceed:
- Turn off the gas and water supply: Make sure both the gas and water lines are closed.
- Remove the access panel: Unscrew the access panel to expose the pilot assembly.
- Remove the old pilot light: Disconnect the gas line and thermocouple, then remove the pilot light assembly.
- Install the new assembly: Attach the new pilot light assembly in place, reconnect the gas line and thermocouple, and replace the access panel.
- Relight the pilot: Follow the steps above to light the new pilot and ensure it’s working correctly.
Relighting a gas geyser’s pilot light is a task most homeowners in Pakistan can handle, whether the water heater has an igniter, an electronic pilot, or requires manual ignition. However, if the pilot won’t stay lit or you suspect a part is faulty, it’s always best to contact a professional for repairs or replacement. Keeping your geyser in good working order, especially during the colder months, will ensure a reliable supply of hot water for your household.
