Bradford White Water Heater Error Code Solid ON (green/red)

The Solid ON LED condition on a Bradford White water heater control indicates that the electronic control board has entered a deliberate shutdown or OFF state. This occurs when the setpoint knob is turned to the OFF position, which commands the control to cease all ignition activity and gas valve operation. The LED illuminating solid (either green or red depending on the control board version) is not an error in the traditional sense. It is a status indicator confirming the control has received and acknowledged the OFF command and is holding in a safe, non-operational state.

During this shutdown period, the control board completes an internal process before fully powering down the LED indicator. The board needs to cycle through its shutdown sequence, which includes closing the gas valve and confirming all burner activity has ceased. Attempting to relight the water heater or turning the setpoint knob before the LED extinguishes completely can interfere with this sequence and may result in a failed ignition attempt or a lockout condition.

This state is entirely normal following an intentional user action at the setpoint knob. The appropriate response is to wait for the LED to go fully dark before proceeding with any relighting procedure. No component failure is indicated, and no fault code is being communicated. If the LED remains illuminated for an extended period without extinguishing, or if the unit fails to relight after the LED goes out, further diagnostics of the gas valve, igniter, or control board may be warranted.
