My boiler fires up ok then after 10mins starts rapid tripping. The pilot light doesn't go out but main burner keeps tripping. An engineer changed the pcb and pressure switch but still no joy!? He reckons I need a new boiler!
When I put hand pressure on the outer casing above the pilot window this stops the tripping and the burner stays on for longer. Must be something to do with the internal pressure. Casing gasket seems ok and tightly secured. Could it be a slow/faulty fan? Hope someone can help as I've just forked out and the problem still isn't fixed.
