Underneath the lower condenser housing is the chassis of the machine in which there is a recess which was filling up with water but only after a few uses.
It turns out that when the pump was engaged,water would be forced out of the rear right fixing of the pump screw,filling this cavity up and once full would then leak onto the floor.
As anyone who has worked on these will know,you can’t look for leaks when the back is on,so I cheated,I filled up the water chamber by hand and then engaged the pump and VOILA!!Water water everywhere.
