How can fix Zanussi FJ1214 water pouring from dispenser drawer?

I have removed, cleaned and replaced the rubber trap connector from drawer to top of drum casing. (Very skimpy spaces for rubber and clips to fix easily) The first time I filled with water OK but water still dribbling from somewhere. The trap pulled off easily in my hand so I went through process all over again. Also checked every possible connection for leaks. Filled with water and very quickly the drawer was not clearing the water fast enough and once more flooding out the drawer casing at the front. Any ideas? I will check that I haven't distorted the rubber trap and obstructed the flow.
ANY OTHER IDEAS?
