Bradford White Water Heater Error Code 1 flash (V1)

The 1 flash code indicates that the pilot flame is detected and the gas control is powered, but the unit is either waiting for the setpoint knob to be turned to a water temperature setting or the water has already reached the target temperature and the heater is in a satisfied standby state. This is a normal status indication, not a fault or error. No service action is required beyond confirming the setpoint knob is properly positioned.

No, the 1 flash code is not a safety warning. It confirms that the pilot flame is present and the control system is powered and functioning. The code indicates normal standby or satisfied operation, meaning the safety and ignition systems are working as intended.

There is no repair cost associated with the 1 flash code because it is not a fault condition. The only action needed is turning the setpoint knob to the desired temperature setting, which requires no parts and no technician visit. If you observe this code alongside an actual lack of hot water or other symptoms, a service call to diagnose an underlying issue could range from $75 to $200 or more depending on your location and what is found.

In most cases, no repair is needed. Simply turn the setpoint knob to your desired water temperature setting if it is currently in a standby or pilot position. If the knob is already set to a temperature and hot water is being delivered normally, the heater is operating correctly and the code reflects a satisfied state. Monitor the unit through one full heating cycle to confirm normal operation.

A reset is not necessary to clear this code. Because the 1 flash status reflects normal operation rather than a lockout or fault condition, the display will automatically change once the setpoint knob is turned to an active temperature setting and the burner fires in response to a heating demand. Resetting the control would require relighting the pilot and would not resolve anything.
