Hi - just looking for some advice. We've been having a regular fault with our boiler whereby the blue ignition light keeps failing. We reset the boiler, it starts up for 5 minutes or so then fails again. This fault is worse in the winter - particularly when windy or in heavy rain. We noticed that our flue terminal cover is missing - could this be the cause of the fault?
