    Boiler Key snapped Worcester 281 Junior combi

    I have a Worcester 281 Junior combi and the white key that I turn for topping up the pressure has snapped and I think it might be in the open position. If I turn the boiler on to heat the radiators will I be causing any damage to the boiler as I am unable to remove the inserted half of the key.

    worcester 28i junior boiler

    I cannot get the boiler to fire up. I have followed the instructions in the manual, but they don't help. The boiler appears to try to fire up, but ignition light does not come on, and I have no heating, and no hot water. Any help would be appreciated.

    Worcester junior

    Called out to boiler repair , found water inside boiler due to wind & rain I suspect as boiler is 6 years old , the fan had water on it's pcb , so I presume it's that as I have 240 going to it , do think the the main pcb would be affected , the quick blow fuses are all ok
