Immergas Victrix fault DL

What it means

Function to correctly perform deaeration of new central heating systems, particularly important for floor/underfloor systems. Cyclically activates the pump and 3-way valve to purge air from the system.

Likely causes

1. Lack of water in the appliance
2. Little water circulation in the system
3. Blocked pump
4. No gas
5. Condensate drain clogged
6. Disconnected PWM signal wire (when boiler is requesting ignition but pump stays in stand-by)
7. Disconnection of the PWM control signal between PCB and pump
8. Boiler electronics not requesting pump ignition (normal, condition OK)
9. Boiler electronics requesting pump ignition but pump not responding (faulty condition, probable disconnection of the PWM signal)
10. Blocked pump (Par. 1.29)
11. Wear or degradation of manifold seals over time
12. Manifold opened for maintenance requiring seal replacement
