Triangle Tube Condensate Fault: Condensate Drain Fault
What the Triangle Tube Condensate Fault 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
What the Triangle Tube Condensate Fault fault means
Condensing operation is being blocked because condensate cannot drain freely, so the boiler shuts down.
On Triangle Tube Prestige Solo and Prestige Excellence stainless condensing boilers, Condensate Fault is a condensate fault. 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
- Lockout, often after very cold weather
- Water pooling near the boiler
- Gurgling sounds from the trap
Common causes of Triangle Tube Condensate Fault
Why this is not a DIY fix
Condensing boilers produce acidic condensate that must drain freely. A blocked or frozen condensate trap/line backs water into the boiler and trips a safety lockout. Clearing and correctly re-routing or protecting the line is best done by a technician to prevent repeats.
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.
