BoilerFaultCodesWhat the manual says
Manufacturer manualAuto filling status monitor: 0: OFF, 1: ON
What causes this fault?
This code appears when the boiler detects that the system water pressure has dropped below the ideal level. It indicates that the internal intelligent filling link has activated to automatically pump fresh water into the central heating circuit. Once the system reaches the required pressure, the message will disappear and the boiler will return to normal operation.
This display is more common in autumn when homeowners first turn their heating back on, as air bubbles or minor leaks during the summer can cause the pressure to dip.
DIY fix possible
