Where is the reset button on an A.O. Smith control valve?

A.O. Smith water heaters typically have a reset button associated with the control valve, especially in gas models. The reset button is a critical safety feature that allows you to reset the water heater's control system in case it encounters specific issues or errors. The location of the reset button on the control valve can vary depending on the specific A.O. Smith water heater model and series. Below, I'll provide a general guide on where to look for and how to use the reset button:

Gas Water Heaters with Electronic Ignition:
For gas water heaters with electronic ignition systems, the reset button is often located near or on the control valve or gas control thermostat. These models typically use electronic ignition systems to light the pilot and main burner, and the reset button is associated with this control system. Here's how to locate and use the reset button:

1. Access the Control Valve Area: The control valve area is usually located on the front of the gas water heater, behind an access panel or door. This panel or door is secured with screws.
2. Remove the Access Door: To access the control valve and reset button, use a screwdriver or an appropriate tool to remove the screws securing the access door. Once the screws are removed, open the door to access the interior components.
3. Locate the Control Valve and Reset Button: Inside the access panel, you should find the gas control valve, which is responsible for regulating the gas supply to the water heater. Near the control valve, you may find the reset button. The reset button is often a small red or black button labeled as "Reset" or "Reignite."
4. Press the Reset Button: If you encounter an issue with your gas water heater and believe that resetting it may resolve the problem, press and hold the reset button. Typically, you would press and hold the reset button for a few seconds to initiate the reset process. Follow the specific instructions provided in your water heater's user manual or any labels on or near the reset button.
5. Monitor the Water Heater: After resetting the water heater, monitor its operation to ensure it functions correctly. The reset process is often used to address minor issues or to reinitiate the ignition sequence if the pilot light has gone out.
Important Safety Considerations:
* Always prioritize safety when working with gas appliances. Before attempting to reset the gas water heater, ensure that the gas supply is turned off, and follow recommended safety procedures.
* Consult your specific A.O. Smith water heater's user manual or documentation for detailed instructions and safety guidelines related to the reset button and troubleshooting procedures.
* If the problem persists or if you are unsure about any aspect of the reset procedure, it is advisable to contact a professional plumber or technician to diagnose and fix the issue correctly and safely.

Please note that the exact location and appearance of the reset button on your A.O. Smith gas water heater may vary depending on the model and year of manufacture. Therefore, always refer to the specific user manual or documentation provided with your water heater for precise instructions and safety precautions related to the reset button and troubleshooting procedures. Safety should always be a top priority when working with gas appliances, and professional assistance is recommended if you are uncertain about any aspect of your water heater's operation or if the issue persists after resetting.
