ford ka - window washer not spraying but water coming into car when used?

when i use my window washer there is no spray to the window, but i noticed that the water is dripping into the car footwell instead.
I assume the hose that transmits the water from the pump has come off the nozzle thing that sprays the window and will need clipping back on...but there seems to be a plastic box cover under the bonnet and i dont know how to access the nozzle without taking this off. before i take it to a garage and incur expense is there an easier way to do this or indeed have i identified the problem correctly?
