Bradford White Water Heater Error Code 5 flashes

Five flashes on a Bradford White water heater indicates a Gas Control V1 temperature sensor fault. This means the gas control valve has detected that its internal temperature sensor is damaged or reading a resistance value outside of the acceptable range. The gas control valve is the component that requires replacement to resolve this fault.

A 5 flashes fault means the water heater's temperature sensor is not functioning correctly, which may prevent the unit from regulating water temperature safely. It is not recommended to continue using the water heater until the fault is diagnosed and the gas control valve is replaced. Operating the unit with a faulty temperature sensor could lead to uncontrolled heating or burner shutdown.

The cost to resolve a 5 flashes fault typically involves the price of a replacement gas control valve plus labor. Gas control valves generally range from $100 to $300 or more depending on the model, and professional labor can add another $100 to $250 depending on your location and the technician's rates. Total repair costs commonly fall in the range of $200 to $550.

The repair for this fault requires replacing the gas control valve, which involves working with gas supply lines and connections. This work should be performed by a licensed plumber or qualified appliance technician. Attempting a gas valve replacement without proper training and tools can create a serious safety hazard.

Resetting the water heater will not permanently clear the 5 flashes error if the gas control valve's temperature sensor is genuinely out of range or damaged. The fault is hardware-based and will return after any reset as long as the underlying component failure exists. Replacement of the gas control valve is the required corrective action.
