Technical description: Ignition: ignition is activated for 2.4 seconds while the gas valve is opened.
What causes this fault?
This fault occurs when the boiler tries to light the gas but can't confirm that a steady flame has been established. The most common reason is that the spark isn't strong enough to ignite the fuel, or the internal sensors are too dirty to 'see' the flame once it starts. In some cases, it may also be caused by an insufficient gas supply or a failing component that controls the gas flow.
