Dodgy flow switch membrane. If your allowed to take the case off boiler see what the flow switch is doing. That's the brass manifold with 4 stainless screws on it, left hand side. It's got a spindle in the middle that pushes on a micro switch to commence ignition sequence.
F.F.S........for fannys sake don't touch the gas pipes or the combustion chamber..........don't go killing yourself
