conditioner doesn't drain into washing machine.?Beko WMA 620W?

We've noticed that after the machine finishes its wash the draw is still full of conditioner and water; we have cleaned the drawer and tested it outside the machine.
If filled with water it will often drain away;but once placed back in the machine with conditioner in the drawer, we have the same problem, the drawer is holding some water in the conditioner section and hasn't run into the washing machine.
