Bradford White Water Heater Error Code 6 flashes (V1)

Six flashes on a Bradford White V1 gas control indicates that the chamber temperature sensor has returned a reading outside its acceptable specification, which can point to a sensor short or a failed sensor element. The gas control shuts down the burner when this fault is detected to prevent unsafe operation. Because the sensor is integrated into the gas control valve, the entire gas control assembly is the primary component involved in this fault.

Start by resetting the gas control valve according to the instructions on the unit. If the 6-flash code reappears, the gas control valve assembly must be replaced, as the chamber temperature sensor is not a separately serviceable part. Replacement of the gas control valve is typically a job for a licensed plumber or appliance technician due to gas line involvement.

Since the fix for a persistent 6-flash error is replacement of the gas control valve assembly, repair costs typically range from around $150 to $400 or more depending on the specific gas control model, labor rates in your area, and whether the unit is under warranty. Checking the remaining warranty on your water heater before purchasing parts is advisable, as gas control components may be covered.

Resetting the gas control is the recommended first step and may clear the code if the fault was intermittent. However, if the 6-flash code returns after the reset, the condition is persistent and the gas control valve assembly will need to be replaced. A reset alone will not correct an underlying sensor short or internal component failure.

No, the water heater should not be operated while displaying this fault code. The 6-flash error means the combustion chamber temperature sensor is not functioning correctly, which prevents the gas control from reliably monitoring burner conditions. Continuing to use the unit without a functioning sensor removes an important safety safeguard.
