Possible cause
Spray arm or feed pipe is distorted ->
spray arm is hitting the basket, the docking
site or the zeolite blower cap.
The drain pump is jammed
Dirty water runs back into the appliance -->
tableware becomes dirty again
Tall narrow receptacles in corners don't get
adequately rinsed.
Detergent dispenser cover is blocked by
utensils (cover does not open fully)
Detergent dispenser cover is blocked by a
tab
Tabs were used in the Quick Wash or
Short programme -> the detergent does
not have time to dissolve in the selected
short programme
Detergent residues in the rinse cycle; de-
tergent transfer
Detergent is extremely lumpy, its cleaning
effect and ability to dissolve are reduced
after prolonged storage
It is physically impossible to prevent
droplets forming on plastic surfaces. Plas-
tics do not retain heat. After drying, sub-
stances that were dissolved in the water
become visible

Troubleshooting
► Checking the components
► Replace defective components
► Checking the drain pump (see IM, Resolving faults yourself)
► Check the action of the drain pump, check that the drain check valve is tight
► Advise customer:
Don't position tall narrow receptacles too obliquely, and don't put them in the
corners.

DosageAssist unit
► Loading the appliance correctly (Page 72)

programme

► Advise customer:
Use fresh new detergent and discard the old
► Advise customer:
Use a more powerful programme (change water more often) (see IM, Programme
