What Solid ON red (V2) means on a Bradford White water heater
On Bradford White water heaters equipped with the V2 control board, a solid red LED that remains continuously illuminated does not indicate a fault condition. Instead, this steady red light signals that the control has been placed into OFF mode. The gas valve and ignition system are intentionally disabled while the unit is in this state, meaning no heating will occur and no pilot flame will be maintained.
The V2 control is a microprocessor-based gas valve controller that monitors system status and communicates operational states through LED blink patterns and solid illumination. When the control enters OFF mode, it holds this solid red indication until the operator takes action to restart the system. This is a normal, expected behavior built into the control logic as a safe shutdown indication rather than a diagnostic warning.
To return the unit to normal operation, the technician or user must initiate a proper restart sequence. Once the pilot is successfully lit and the control confirms flame presence, the solid red LED will extinguish and the control will resume standard operation. No components are faulty when this indication is present. The key distinction to confirm is that the LED is fully solid and not blinking, since blink patterns on V2 controls do correspond to actual fault codes requiring diagnosis.

Common causes of Solid ON red (V2)
- 01
Control manually placed in OFF mode
Wiring / connectionThe most common reason for this indication is that someone turned the control to the OFF position, either intentionally for maintenance, vacation, or shutdown purposes. Check the control knob or mode setting to confirm it was set to OFF.
- 02
Pilot outage triggering automatic shutdown
Wiring / connectionIf the pilot flame was lost during operation, the V2 control may have transitioned to OFF mode as part of its shutdown sequence. Inspect the pilot assembly and verify whether a flame is present before attempting a restart.
- 03
Recent power interruption or reset
Wiring / connectionA power interruption or a manual reset of the control can cause the unit to default to OFF mode upon restoration. This is a normal protective behavior that requires a fresh startup cycle.
- 04
Previous fault condition was cleared
Wiring / connectionIf the control was previously displaying a blink-code fault and was manually reset to clear it, the control may land in OFF mode before the restart cycle is completed. Review service history to determine if a prior fault was addressed.
