my boiler is not firing up. one day it was fine and the other it just stopped working altogether. it will not reset or fire back up. someone told me it could be a fault in the programmer. does anyone help?

My glow worm 40ff has just packed in , had a problem with it last year it was dry joints on the circuit board apparently it is a common problem with this board it was ok after i sorted the solder joints out but it has gone again so i have gone out and bought the update pcb for 105 quid this time.
