BoilerFaultCodesTechnical description
Maximum ignition time
What causes this fault?
This fault occurs when the boiler's internal computer tries to light the gas burner but cannot confirm a stable flame within the set safety time limit. It is usually caused by a worn ignition lead failing to create a spark or a layer of carbon buildup on the sensors preventing the boiler from 'seeing' the flame it has created.
This issue often surfaces during the first cold snap of autumn when the boiler is pushed to run at maximum power after being relatively idle over the summer.
Engineer required
This is a high severity fault. Stop using the boiler and call a Gas Safe registered engineer. Do not attempt gas-related repairs yourself.
