How to Reset Water Heater Pilot: A Step-by-Step Guide
Having a functioning water heater pilot is essential for a consistent and warm water supply. However, sometimes the pilot light may go out due to various reasons such as faulty thermocouple, worn-out igniter, or improper installation. Fortunately, resetting the water heater pilot is a relatively straightforward process that can be done by a homeowner with minimal plumbing knowledge. In this article, we will guide you through the steps on how to reset water heater pilot.
Why Do You Need to Reset Water Heater Pilot?
Resetting the water heater pilot is necessary when the light goes out due to:
• Faulty Thermocouple: The thermocouple is responsible for sensing the pilot light flame and shutting off the gas supply when the flame goes out. If the thermocouple is faulty, it may not shut off the gas supply, leading to a buildup of gas that can cause a fire.
• Worn-out Igniter: The igniter is responsible for lighting the pilot light. Over time, the igniter may wear out, preventing the pilot light from lighting.
• Improper Installation: Improper installation of the water heater can cause the pilot light to go out.
What You Need to Reset Water Heater Pilot
Before attempting to reset the water heater pilot, make sure you have the following:
• Owner’s Manual: The owner’s manual is essential in understanding the specific instructions for your water heater model.
• Tools: You may need a screwdriver, wrench, or pliers to perform the reset process.
• Safety Precautions: Always turn off the gas supply to the water heater before attempting to reset the pilot light.
Step-by-Step Instructions to Reset Water Heater Pilot
Step 1: Turn Off the Gas Supply
- Locate the gas shut-off valve for your water heater.
- Turn the valve clockwise to shut off the gas supply. Make sure the gas supply is completely shut off before proceeding.
**Step 2: Remove the Igniter Cap**
- Locate the igniter cap on top of the water heater. It may be held in place by a screw or clip.
- Remove the cap by unscrewing or unclipping it. Be careful not to touch any of the internal components.
Step 3: Access the Pilot Light
- Locate the pilot light on the water heater. It may be located at the bottom or side of the unit.
- Use a screwdriver or wrench to remove any screws or clips holding the pilot light cover in place.
- Carefully lift the cover and access the pilot light assembly.
Step 4: Relight the Pilot Light
- Use a match or lighter to light the pilot light. Hold the flame to the pilot light for about 30 seconds to 1 minute to ensure the light is stable.
- Once the pilot light is lit, release the knob or button to allow gas to flow to the main burner.
Step 5: Check for Leak
- Turn the gas supply back on and wait for the water heater to heat up.
- Check for any leaks around the pilot light assembly by running the water heater for about 10-15 minutes.
Tips and Precautions
- Make sure you have a clear understanding of the steps before attempting to reset the pilot light.
- Turn off the gas supply before starting the reset process to prevent any accidents.
- Be careful not to touch any of the internal components to avoid damage or electrical shock.
- If you are unsure or uncomfortable with the reset process, it is recommended to call a professional plumber.
Common Mistakes to Avoid
• Not turning off the gas supply: Failure to turn off the gas supply can cause a buildup of gas that can lead to a fire.
• Not allowing the pilot light to stabilize: Not allowing the pilot light to stabilize can cause it to go out again.
• Not checking for leaks: Failing to check for leaks can cause water damage or electrical shock.
