What 8 flashes means on a Bradford White water heater

The 8-flash error code on a Bradford White water heater indicates a fault condition designated as Gas Control V1. Specifically, the control board has detected that the standing pilot flame remains active even though the setpoint knob has been turned to the OFF position. Under normal operation, rotating the knob to OFF should close the pilot valve completely, extinguishing the pilot flame. When the control detects that the pilot signal persists despite the OFF command, it logs this fault to alert the technician that the pilot valve is not responding correctly to the control signal.

The root cause is a pilot valve that has become stuck in the open position. The pilot valve is an internal component of the gas control valve assembly. When this valve fails mechanically, it can no longer fully close, allowing gas to continue flowing to the pilot burner regardless of knob position. This is not a wiring or thermocouple fault. The failure is internal to the gas control valve itself, meaning individual sub-components cannot be serviced or replaced separately.

Because the pilot valve is integrated into the gas control assembly, the correct corrective action is full replacement of the gas control valve. Continuing to operate the water heater with this fault present means gas is flowing to the pilot circuit in an uncontrolled manner relative to the knob position, which represents both a gas waste concern and a potential safety issue. Technicians should not attempt to disassemble or repair the gas control internally. Replace the entire gas control valve to resolve the 8-flash condition.

Common causes of 8 flashes

  1. 01

    Pilot valve stuck open inside the gas control

    Part replacement

    The pilot valve inside the gas control assembly has mechanically failed and can no longer close when commanded by the knob position. This is the primary cause of the 8-flash code and cannot be repaired without replacing the entire gas control valve.

  2. 02

    Internal gas control valve wear or debris

    Part replacement

    Over time, sediment, corrosion, or internal wear can prevent the pilot valve seat from seating properly, keeping the valve in a partially or fully open state even when the control knob is set to OFF.

  3. 03

    Gas control valve manufacturing defect

    Part replacement

    In some cases, a gas control valve may develop an internal failure prematurely due to a defect in the valve mechanism. If the unit is relatively new and this fault appears, the gas control may be covered under the unit's warranty.

Frequently asked questions about 8 flashes

What does 8 flashes mean on a Bradford White water_heater?
Eight flashes on a Bradford White water heater indicate a Gas Control V1 fault, meaning the standing pilot flame is staying on even when the setpoint knob is in the OFF position. This points to a pilot valve that is stuck in the open position inside the gas control assembly. The gas control valve must be replaced to clear this fault.
Can I fix the 8-flash error myself on a Bradford White water heater?
The 8-flash fault requires replacement of the gas control valve, which is not a DIY repair for most homeowners. The repair involves disconnecting gas lines and properly sealing new connections, which requires the appropriate tools, skills, and knowledge of local gas codes. A licensed plumber or appliance technician should perform this repair.
Is it safe to use my Bradford White water heater when it shows 8 flashes?
The 8-flash code indicates the pilot valve is stuck open, meaning gas is flowing to the pilot circuit even when the knob is set to OFF. This represents an uncontrolled gas flow condition and should be taken seriously. It is advisable to shut off the gas supply to the unit and contact a qualified technician promptly rather than continuing to operate the water heater.
Will resetting the water heater clear the 8-flash error code?
No, resetting the unit will not clear the 8-flash error. The fault is caused by a mechanically failed pilot valve inside the gas control assembly, not a transient electrical or sensor error. The fault condition will persist and return immediately because the underlying hardware failure remains present until the gas control valve is replaced.
How much does it cost to fix the 8-flash error on a Bradford White water heater?
The cost to repair the 8-flash fault typically ranges from around $200 to $600 or more, depending on the specific gas control valve required for the model, local labor rates, and whether any additional parts or permits are needed. If the water heater is still within its warranty period, the gas control valve may be covered, potentially reducing out-of-pocket costs to labor only.
