Mend Ravenheat 820/20 Boiler Heating Breakdown

Has my Ravenheat 820/20 boiler broken down?

I came home this evening only to find the boiler making a strange pumping sound. I noticed water gushing out from the overflow pipe outside. I immediately turned off the water supply. Should I be worried?

I would be worried aswel if that was my boiler. It seems like a problem with expansion vessel.
