Compartment 3 is for fabric conditioner (which is the furthest right as you look at the machine from the front), you were right ... it does have a flower type imprint on it.
Good luck with your machine, you will need it ... I have had several problems with mine! although I have sorted them all out myself, so if you get a problem with it feel free to ask me .. I might know the answer !!
