Common Viessmann Faults We Repair in Mission
Viessmann reports problems through fault codes shown on the Vitotronic control display. These are the faults our technicians diagnose most often on Mission service calls:
- Ignition / Flame Faults
The burner fails to establish or hold flame — typically a worn ionization electrode, igniter wear, or combustion drift. Vitodens units log the fault on the Vitotronic display, which guides our diagnosis.
- Burner Lockout on Overtemperature
Restricted system flow — air-locked loops, a failing circulator, or closed zones — drives the supply temperature beyond limits and locks the burner out.
- Condensate Drainage Faults
Blocked traps or frozen exterior condensate lines shut the boiler down during Lower Mainland cold snaps.
- Fan and Venting Faults
The variable-speed fan must hit target speed before ignition; bearing wear or vent restrictions trigger lockouts.
- Sensor Drift
Aging supply/return sensors feed the control bad data, causing erratic modulation and nuisance lockouts.
