how do I fix my saunier duval 620f?

Hi, Ive just fitted a new pump to my saunier duval boiler. Within 30 mins of it starting up, water seemed to be pouring out the base of the combi unit. It was still running, I killed the electric, switched of the gas, and thought what now....
Ive opened the bleed valve and drained the system, has any one an idea on what it could be, even a starting point would be of great assistance.. many thanks

The information is vague. Was it leaking before changing the pump, where can you see the leak. Is it coming from the safety valve, middle connection on the jig.
