How to relight a pilot light on a hot water heater A.O. Smith with an ignition button?

Relighting the pilot light on an A.O. Smith hot water heater with an ignition button is a relatively straightforward process, but it's essential to follow the steps carefully to ensure safety and successful ignition. The presence of an ignition button typically indicates an electronic ignition system, which simplifies the relighting process. Here are step-by-step instructions on how to relight the pilot light:

Important Safety Precautions:
* Before attempting to relight the pilot light, ensure there is no smell of gas in the area. If you detect a strong gas odor, turn off the gas supply to the water heater and ventilate the area immediately. Do not proceed until the gas odor has dissipated.
* Never use an open flame, such as a lighter or match, to check for gas leaks. Use a gas leak detection solution or soapy water to identify any potential gas leaks.
* If you are uncomfortable or unsure about any step in the process, it's best to contact a professional plumber or technician to relight the pilot light for you.

Steps to Relight the Pilot Light:
1. Turn the Temperature Dial to "Off": Locate the temperature control dial on the water heater, usually found near the bottom. Turn it to the "Off" or "Pilot" position to shut off the burner and prevent gas from flowing while you work on relighting the pilot.
2. Access the Control Panel: Open the access panel or door on the water heater. This panel is typically on the front and secured with screws. Use a screwdriver to remove the screws and access the interior.
3. Locate the Pilot Assembly: Inside the control panel, you should see the pilot assembly. It consists of a small tube leading to the pilot burner and a control knob or button.
4. Press and Hold the Ignition Button: The ignition button is typically a red or black button near the pilot assembly. Press and hold this button down. While holding it down, you'll also need to press the control knob or button on the pilot assembly.
5. Listen for Clicking or Sparking: While holding both buttons down, listen for a clicking or sparking sound. This is the electronic ignition system attempting to ignite the pilot.
6. Observe the Pilot Flame: Continue to hold down the buttons for about 30 seconds, even if you don't see the pilot flame initially. If the ignition is successful, the pilot flame will ignite and remain lit.
7. Release the Buttons: After about 30 seconds, release both the ignition button and the control knob or button on the pilot assembly. The pilot flame should continue to burn steadily.
8. Turn the Temperature Dial Back to Your Desired Setting: Once the pilot flame is stable, turn the temperature control dial back to your desired water temperature setting. This will allow the burner to operate and heat the water as needed.
9. Close the Access Panel: Close the access panel securely and reattach any screws that were removed to secure the panel.
10. Monitor the Water Heater: Keep an eye on the water heater to ensure it operates correctly. The pilot light should remain lit, and the main burner should ignite when hot water is needed.

Additional Tips:
* If the pilot light does not ignite after several attempts, or if it goes out shortly after ignition, it may indicate an issue with the thermocouple or other components. In such cases, it's advisable to contact a professional technician for further diagnosis and repair.
* Always refer to your specific A.O. Smith water heater's user manual for model-specific instructions and safety guidelines related to lighting the pilot light and maintenance.
* Regularly inspect and maintain your water heater to prevent issues with the pilot light. This includes checking for sediment buildup, ensuring proper ventilation, and replacing any worn-out components as needed.
* If you experience repeated pilot light issues or safety concerns, it's best to seek professional assistance to diagnose and address any underlying problems with your water heater.

Relighting the pilot light on an A.O. Smith hot water heater with an ignition button is a routine maintenance task that can help ensure your water heater operates efficiently and provides a reliable supply of hot water.
