Bradford White Flame Loss: Flame Loss / Flame Failure
What the Bradford White Flame Loss fault means, what causes it, and why it's a job for a licensed BC gas technician — not a DIY reset.
Severity
High — needs prompt professional attention
Gas safety first
This fault involves gas, combustion or venting. If you smell gas (rotten-egg odour), hear hissing, or feel unwell, leave the building immediately and call 911 or FortisBC at 1-800-663-9911 from outside. Do not flip switches or relight anything. For all other cases, switch the boiler off and call a licensed gas technician.
What the Bradford White Flame Loss fault means
Flame was lost during operation, triggering a safety lockout.
On Bradford White Brute Elite condensing series, Flame Loss is a flame failure. It is a protective response — the boiler is telling you something needs attention, and the safe, lasting fix is a proper diagnosis rather than repeated resets.
Symptoms you may notice

Common causes of Bradford White Flame Loss
Why this is not a DIY fix
Loss-of-flame and false-flame faults point to the flame-rectification circuit, a dirty flame sensor, a failing gas valve, or unstable combustion. Confirming the cause needs live flame-current (microamp) readings and combustion analysis — instrumented gas work reserved for licensed technicians.
In British Columbia, gas work must be performed by a TSBC-licensed gas fitter. GasBoilers.ca — a CanroHeat division — sends Red Seal–certified, gas-licensed technicians who diagnose the true cause, repair it correctly, and verify safe operation before they leave.
