What 8 flashes (V1) means on a Bradford White water heater
The 8 flashes (V1) error code on a Bradford White water heater indicates that the control circuit has detected a standing pilot flame while the setpoint knob is positioned in the OFF setting. Under normal operation, turning the knob to OFF should close the pilot valve and extinguish the pilot flame entirely. When the control board detects a thermocouple or flame sensor signal indicating an active pilot despite the OFF command, it registers this fault condition and begins the 8-flash sequence.
The root cause is almost always a pilot valve that has become stuck in the open position within the gas control valve assembly. The pilot valve is an internal component of the gas control unit, not a separately serviceable part in the field. A stuck-open pilot valve allows gas to continue flowing to the pilot burner regardless of knob position, creating both a fault condition and a potential safety concern. Contamination, corrosion, or mechanical wear of the valve seat or solenoid internals can all cause this type of failure.
Because the pilot valve is integrated into the gas control assembly, the corrective action is replacement of the entire gas control unit. There is no field-level repair for a stuck pilot valve. Attempting to operate the water heater while this fault is active is not recommended, as the gas control is not responding correctly to operator input.

Common causes of 8 flashes (V1)
- 01
Pilot valve stuck open inside gas control
Part replacementThe pilot valve solenoid or seat within the gas control assembly has failed in the open position, allowing gas to flow to the pilot burner even with the knob set to OFF. This is the primary cause of this fault and requires gas control replacement.
- 02
Contamination or debris in pilot valve seat
Part replacementSediment, corrosion byproducts, or debris can lodge in the pilot valve seat and prevent it from seating fully when commanded to close. The valve remains partially or fully open as a result.
- 03
Internal corrosion of gas control assembly
Part replacementMoisture intrusion or long-term corrosion inside the gas control can compromise the mechanical components of the pilot valve, causing it to bind in the open position.
- 04
Failed gas control solenoid
Part replacementThe electrical solenoid that actuates the pilot valve may have failed in an energized or mechanically locked state, preventing the valve from closing when the knob is moved to OFF.
