What the Short flash once per second error code actually means

This flashing light is not a warning or problem. It simply means your water heater is working normally and currently heating the water in the tank because the temperature dropped below your selected setting. Once the water reaches the right temperature, the heating will stop and the flash pattern will change.

Questions people ask about Short flash once per second

What does Short flash once per second mean on a Bradford White water heater?
A short flash once per second from the status LED on a Bradford White water heater indicates that the gas control valve is calling for heat. The thermostat has detected that the tank water temperature is below the selected setpoint and the unit is actively in a heating cycle. This is a normal operating status, not a fault code.
Is it safe to use my water heater while this light is flashing?
Yes, this flash pattern confirms the heater is in a normal heating cycle and is completely safe to operate. There is no fault condition associated with this status. You can continue using hot water as normal.
How much does it cost to repair this issue on a Bradford White water heater?
No repair or parts are needed for this condition since it represents normal operation. If a technician visit is requested to confirm the unit is working correctly, expect a standard diagnostic service call fee, which typically ranges from $75 to $150 depending on your location and provider.
Do I need to fix anything when I see this flash pattern?
No repair is needed when the once-per-second short flash is displayed. The unit is operating as designed. If the burner does not appear to be running while this pattern is active, or if the water never heats up after a prolonged period, then further diagnostics on the gas supply, ignition system, or gas control valve would be warranted.
Will resetting the water heater clear this flash pattern?
Resetting the unit is unnecessary and will not change the underlying condition. The flash pattern will only change once the water temperature reaches the thermostat setpoint and the call for heat ends. Resetting during an active heating cycle would simply restart the sequence.
