F.22 is a low pressure fault. Repressure the boiler to around 1–1.5 bar using the filling loop. If the pressure keeps dropping back, there’s a leak somewhere in the system that needs finding.
F.28 means the boiler can’t detect gas at ignition. First check your gas meter is on and other gas appliances work. If they do, the fault is likely an internal gas valve issue — call us.
Repairs start from £85. We’ll give you a clear quote before starting any work.
