Bradford White Water Heater Error Code 5 flash

The 5-flash code means the control system has detected a pilot flame signal when the pilot should be off, indicating the pilot valve is stuck in the open position. This is classified as an undesired or false flame condition. The heater will lock out to prevent uncontrolled gas flow until the issue is resolved. Replacing the gas control assembly is the required fix.

Yes, this fault involves a pilot valve that is stuck open, meaning gas may be flowing through the pilot circuit without being commanded to do so. The control system locks out the heater when it detects this condition, which is a protective response. Until the gas control is replaced, you should treat the situation seriously and consider shutting off the gas supply to the water heater if you smell gas or have any concerns about safety.

The cost to repair this fault depends on the specific model and labor rates in your area, but gas control valve assemblies for Bradford White water heaters typically range from roughly 150 to 350 dollars for the part alone. With professional labor, total repair costs generally fall in the range of 250 to 600 dollars. Getting a quote from a licensed technician before proceeding is recommended, especially since an older unit near the end of its service life may be a candidate for replacement instead.

The repair requires replacing the gas control valve assembly, which involves working directly with the gas supply line and should only be performed by a qualified technician licensed to work on gas appliances. A knowledgeable DIYer with gas appliance experience may be able to perform the swap, but local codes in many areas require a licensed plumber or gas technician for gas valve work. Do not attempt this repair without proper knowledge of gas line safety procedures.

Resetting the unit will not resolve the 5-flash fault because the underlying cause is a mechanical failure of the pilot valve inside the gas control assembly. The stuck valve will continue to allow gas flow regardless of a reset, and the control system will detect the undesired flame condition again and return to lockout. A permanent fix requires replacing the gas control assembly.
