how can I find out how my servis rainwave 900 washer drier works?

I have just bought a flat with a service rainwave 900 washer drier and would like to know how to operate it. I want to clean the powder dispenser drawer but don't know how to remove it. Also sitting on top of the machine is a plastic thing that looks like an elongated funnel and looks like it might fit in the dispenser drawer. Does it? What is it for? Is there anywhere I can get an instruction manual? Please help.
