Triangle Tube fault codes can vary by model and series. Use this as a guide — the same code can have more than one cause. Our Technical Safety BC–licensed technicians read the code, confirm it against your unit's manual, and diagnose the true cause before any repair.
Likely causes of Triangle Tube error E02
- Gas supply shut off or insufficient gas pressure
- Dirty, cracked, or misaligned ignition/flame sensor electrode
- Faulty ignition control module or igniter
- Air trapped in the gas line (recently serviced gas)
- Gas valve fault or wiring connection issue
What you can safely check
- Confirm the gas is on by checking that another gas appliance (stove, water heater) works
- Make sure the boiler's outdoor vent terminal is clear of snow, leaves, or debris
Beyond these checks, do not open the unit or touch gas/electrical parts — BC law requires a licensed gas fitter. Call us for a proper diagnosis.
Error E02 usually leaves you without heat or hot water and can indicate a safety-related fault. Don't keep resetting it — call for priority after-hours Triangle Tube repair.
