Immergas Victrix fault 61

Air in circulator

Gas boiler

What it means

Air is detected inside the pump; the pump cannot work.

Likely causes

  1. Air trapped inside the pump/circulator
  2. Air in central heating circuit
  3. Low power supply voltage
  4. Rotor seized
  5. Electrical error in pump
  6. Lack of water in the appliance
  7. Little water circulation in the system
  8. Blocked pump
  9. Blocked pump (Par. 1.29)
  10. Boiler electronics not requesting pump ignition (normal, condition OK)
  11. Boiler electronics requesting pump ignition but pump not responding (faulty condition, probable disconnection of the PWM signal)
  12. Disconnected PWM signal wire (when boiler is requesting ignition but pump stays in stand-by)
  13. Disconnection of the PWM control signal between PCB and pump
  14. Long period of inactivity causing pump/rotor seizure

Where to start

  1. Vent the pump
  2. Vent the pump and the central heating circuit
  3. Check pump symbol 1 (red) status on the pump head

Safety: Isolate gas and power before you open the case. If you have been into the gas side, do a tightness test, and a combustion and flue check before you hand back. Gas Safe (UK) or RGI (Ireland) work only.
