Common Burnham Boiler Problems
Burnham builds reliable, high-efficiency boilers, but no gas appliance is immune to faults over a long BC heating season. Below are the problem areas we most commonly diagnose on Burnham Alta, Aspen and Independence series, what they tend to look like, and — importantly — why each one is work for a licensed gas technician rather than a DIY fix.
Most common Burnham fault areas
Burnham controls report faults across several systems. These are the categories we see most often, drawn from Burnham's own diagnostic codes:
- Ignition fault — typical signs: no heat or no hot water. Example Burnham codes: Ignition Lockout.
- Flame failure — typical signs: boiler fires briefly then shuts down. Example Burnham codes: Flame Loss.
- Over-temperature / high-limit — typical signs: boiler locks out under load. Example Burnham codes: High Limit.
- Combustion-fan fault — typical signs: no heat or hot water. Example Burnham codes: Fan Fault.
- Air-pressure / venting fault — typical signs: lockout, often worse in wind, rain or cold snaps. Example Burnham codes: APS Fault.
- System water-pressure fault — typical signs: pressure gauge reading low (or very high). Example Burnham codes: Low Water Pressure.
- Temperature-sensor fault — typical signs: erratic heating or hot-water temperature. Example Burnham codes: Supply Sensor Fault.
- Condensate fault — typical signs: lockout, often after very cold weather. Example Burnham codes: Condensate Fault.
Symptoms you might notice first
- No heat — often ignition, flame-sensing, circulation or a sensor fault.
- No hot water (combi models) — frequently the plate heat exchanger, flow sensor or a DHW fault.
- Leaking or dropping pressure — a seal, the expansion tank, or the relief valve.
- Banging, gurgling or "kettling" noises — usually air or scale, sometimes circulation.
- Lockouts that return after a reset — a genuine fault the boiler is protecting against.
Why Burnham faults are not a DIY fix
Every one of these areas touches the sealed gas circuit, combustion, or safety controls. In British Columbia, diagnosing and repairing them legally requires a licensed gas fitter, and proper diagnosis needs combustion analysis and manometer gas-pressure testing. Repeatedly resetting a locked-out boiler can be dangerous — the fault code exists to protect you. The right move is to read the code, attempt at most one reset, and call a technician if it returns.
Burnham common problems — FAQ
What are the most common problems with Burnham boilers?
Across Greater Vancouver, the Burnham faults we see most are ignition and flame-sensing issues, air-pressure/venting faults (often worse in cold or windy weather), circulation and overheat lockouts, and pressure loss. The exact cause is confirmed with proper diagnosis, not guesswork.
Why does my Burnham boiler keep locking out?
A repeating lockout means the underlying condition — ignition, flame, venting, pressure or temperature — is still present. The reset clears the code but not the cause. If your Burnham boiler locks out again after one reset, switch it off and book a diagnosis.
Can I fix a Burnham fault code myself?
You can safely read the code and reset once. Beyond that, Burnham faults involve gas, combustion or safety systems that BC law reserves for licensed gas fitters — and DIY attempts can void your warranty and create a hazard.
