Due to the recent very wet weather and strong winds, my boiler has gone into fault with flashing red light, I have dried the boiler out, but when running both with hot water and heating the gas burners ignite, the go out after 10 to 20 seconds, this pattern repeats a few times then goes into flashing light over central heating control, the burner light on the boiler does not come on.

Thanks AWOL the fault after downloading fault finding from Worcester Bosch, and testing turned out to be PCB faulty, probably caused by water leaking into boiler.
