Worcester 28i boiler pcb fault

Help

My worcester 28i rsf combi boiler flame is going on & off, when you drop down the plastic case holding the printed circuit board it works ok, I've looked at the pcb but there are no obvious signs of burning or faulty components, does anyone know what could be causing this?

Its perhaps more likely to be a wire or connection but in reality it could be anything!

Without being there we cannot tell you what it is.
