The hard grey hose inside the flexible one is not aligned up right so it will fit in the slot at the bottom where the flexible hose clicks in by the red tab. Remove the whole piece by pushing the red tab and then move the wand around untill it fits through the bottom then place it back on the machine. If this is not aligned right the hard wand hose pipe will not go down enough and so the wand will not go all the way down and snap.into.place.
