What Bradford White Code 1 Flash Per Second (Weak Pilot) Means
A short flash once every second on the ICON gas control means the control board sensed a weak pilot signal during the previous heating cycle. The pilot may have lit, but the flame-sensing current returning to the board was below the threshold the control expects for safe, reliable operation. Bradford White built this indicator in so a licensed technician can catch a marginal pilot before it deteriorates into a no-heat lockout.
Bradford White uses the status LED on the gas control as a built-in diagnostic aid for service professionals. The flash pattern is repeated with a three-second pause so a technician can read it accurately on site. Knowing that the code points to a weak or unstable pilot flame signal was detected on the last call for heat gives our team a precise starting point for diagnosis the moment we arrive.
What Typically Causes the 1 Flash Per Second (Weak Pilot) Code
On Bradford White water heaters, the 1 Flash Per Second (Weak Pilot) code is most commonly associated with the following conditions. This list is provided for your understanding only — confirming and correcting any of these is gas-appliance work that should be left to a licensed technician:
- An unstable or undersized pilot flame
- A pilot tube that is blocked or restricted
- Oxidation build-up on the pilot electrode or flame sensor
- Damaged wiring to the pilot assembly or a loose connection at the gas valve
Is the 1 Flash Per Second (Weak Pilot) Code a Safety Concern?
A weak pilot signal is not usually an immediate emergency, but it should not be ignored. A marginal pilot can drop out entirely, and any time a gas appliance struggles to maintain a stable flame it warrants prompt professional attention to rule out a gas-delivery or combustion problem. If you also smell gas, leave the home and call your gas utility first.
How ROMA Repairs It
When you call ROMA about a Bradford White 1 Flash Per Second (Weak Pilot) code, our gas-licensed technicians follow a methodical, manufacturer-aligned process rather than guessing:
- A gas-licensed technician confirms the 1 Flash Per Second (Weak Pilot) code by reading the status LED flash pattern directly on the control
- Measure the flame-sensing micro-amp signal against Bradford White specification
- Inspect and service the pilot assembly, electrode, and tubing
- Confirm gas supply pressure is within spec
- Genuine Bradford White OEM parts are used for any gas valve, sensor, switch, or control replacement
- Combustion, draft, and safe operation are verified before the water heater is returned to service

We never bypass a safety device to get a unit running — if a control, sensor, or switch is part of the safety system, it is repaired or replaced correctly.
