BoilerFaultCodesTechnical description
Ignition sequence (hot water operation)
What causes this fault?
This code appears when the boiler begins its internal sequence to heat the water for your taps or cylinder. It is triggered by the system's sensors detecting a demand for hot water, signaling the fan to start and the gas valve to prepare for ignition. This is a standard part of the boiler's operation and does not indicate a breakdown.
DIY fix possible
No action required; this is a normal status code.Wait for the boiler to complete its ignition sequence.Check that your hot water taps are running if you expect the boiler to be on.
