What the 1 flash every 4 seconds (green) error code actually means

Your Bradford White water heater is working normally. The pilot light is on and the heater is either waiting for you to set the temperature dial, or the water in the tank is already hot enough and the burner does not need to run right now. No repairs are needed.

Questions people ask about 1 flash every 4 seconds (green)

What does 1 flash every 4 seconds (green) mean on a Bradford White water heater?
This slow green flash pattern means the pilot is lit, the gas valve is powered, and the main burner is currently off. The system is either in thermostat-satisfied standby because the water is already at the set temperature, or the setpoint knob has not been turned to a temperature setting. It is a normal operational status, not a fault.
Is it safe to continue using my water heater when it shows this green flash pattern?
Yes, this pattern is a sign of normal, safe operation. The pilot is confirmed lit and the control system is functioning correctly. There is no unsafe condition associated with this indicator.
How much does it cost to fix a Bradford White water heater showing 1 green flash every 4 seconds?
There is no cost associated with this indicator because it does not represent a fault or failure. Simply turning the setpoint knob to the desired water temperature is all that is required. If the burner still does not fire after setting the knob correctly, further diagnostics would be needed at that point.
Do I need to fix anything when I see 1 green flash every 4 seconds on my Bradford White water heater?
No repair is needed. This indicator pattern confirms the unit is healthy and ready. If you are not getting hot water, check that the setpoint knob is turned to your desired temperature. Once the knob is set and the tank temperature drops below the setpoint, the burner will fire automatically.
Will resetting my Bradford White water heater clear this green flash pattern?
Resetting the unit is not necessary and will not change the underlying condition. The pattern will continue as long as the thermostat is satisfied or the setpoint knob is not configured. Setting the knob to the correct temperature position is the appropriate action, not a reset.
