Frontloaders...
Spatz:
Two things that you have to be careful of:
I see that there is a dirty mark on the door seal; this means that either there is insufficient detergent, or incorrect detergent, or possibly iron content in the water. Frontloaders require a hot maintenance cycle to be run, with a quality powder, to wash away any residues (dirt, stale detergent, etc).
Secondly, liquid detergents: if placed into the drawer, they have a tendency to run straight into the tub, then down into the sump, where they are not used for washing. In the UK, washer manufacturers usually recommend use of a dosing ball, placed on top of the clothes, in the drum.
