Bradford White Water Heater Error Code 1 flash

One flash on a Bradford White water heater with Gas Control V1 is a normal status indicator, not a fault code. It means the pilot flame is lit and the gas control is powered, and the unit is either waiting for the setpoint knob to be turned to a temperature setting or the water is already at the target temperature. No corrective action is needed if the unit is otherwise heating water normally.

No, the 1 flash code is not a safety warning. It confirms that the pilot is lit and the control system is powered and functioning. The only time you should take action is if the pilot will not remain lit, in which case you should follow the lighting and diagnostic steps before continuing to operate the unit.

If the pilot assembly needs replacement, parts typically range from around $15 to $50 depending on the specific assembly required. A gas control valve replacement is more involved, with parts generally ranging from $80 to $200 or more, plus labor if a technician is hired. Costs vary by region and the specific model of the water heater.

In most cases, no fix is required since 1 flash indicates normal operation. If the water heater is not producing hot water, turn the setpoint knob from the pilot position to your desired temperature setting. If the pilot will not stay lit, replace the pilot assembly first. If the problem continues after replacing the pilot assembly, the gas control valve should be replaced.

A reset is not necessary to clear the 1 flash code because it is a normal status indication rather than a fault. The code will change automatically once a heating cycle begins after you set the temperature knob, or it will continue to display during normal satisfied standby. Resetting does not address any underlying pilot or gas control issue if one exists.
