Bradford White Water Heater Error Code 1 flash

The 1 flash status code on a Bradford White water heater equipped with the Gas Control V1 system is a normal operational indicator rather than a fault condition. It signals one of two states: either the pilot flame has been successfully established and the gas control valve is powered but is waiting for the setpoint knob to be rotated to an active water temperature setting, or the water heater has reached its target temperature and is in a satisfied, standby condition. In both cases, the pilot is confirmed lit and the control board is functioning correctly.

The Gas Control V1 integrates the thermostat, gas valve, and ignition status monitoring into a single unit. The LED flash pattern is how this controller communicates system status. A single flash repeating indicates the system has confirmed pilot presence through the thermocouple or thermopile circuit and is operating within normal parameters. No active heating demand exists at the moment the code is displayed, either because the knob has not been set or because the stored water has already reached the desired temperature.

If the unit is not heating water despite the 1 flash code appearing, the most likely explanation is that the setpoint knob was left in the pilot position after lighting. Rotating the knob to the desired temperature setting should initiate normal burner operation. If the pilot will not remain lit after lighting attempts, the pilot assembly itself may be faulty and should be replaced. If replacing the pilot assembly does not resolve persistent pilot outage, the gas control valve assembly is the next component to evaluate and replace.
