Washing instructions What are the three receptacles found in the drawer on the left side of the washing machine?

My book says for the Axxis WFL 2050/WFL 2060 : from the left while looking at it from the front: detergent for wash, stain remover, middle: fabric softener, fabric conditioner, right one: detergent for soaking agent. (Do not use chlorice bleach in this wasking machine).

Thats where you put the detergent and fabric softener, etc..
