Isn't there a flow switch somewhere in a combi boiler set up?

Either flow switch,diverter valve or heat exchanger,and if its the heat ex,maybe cheaper in the long run to scrap the boiler,especially if its an old one. :y

If its a combi then its probably the pressure diapram in the flow switch

Got someone coming out tomorow.  Hope there in the Christmas spirit & settle for a mince pie & a few cans. Had to get a new washing machine a couple of weeks ago. Everything seems to go wrong this time of year.
