tab
► Advise customer:

Tabs were used in the Quick Wash or
Short programme -> the detergent does
not have time to dissolve in the selected
short programme
► Advise customer:
Tabs take too long to dissolve; use a powder detergent or select a more intensive
programme
Detergent residues in the rinse cycle; de-
tergent transfer
► Check the action of the drain pump, check that the drain check valve is tight
Residues on the utensils or in the
appliance - undissolved detergent
Detergent is extremely lumpy, its cleaning
effect and ability to dissolve are reduced
after prolonged storage
► Advise customer:
Use fresh new detergent and discard the old
Residues on the utensils or in the
appliance - water stains
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
► Advise customer:
Use a more powerful programme (change water more often) (see IM, Programme
overview)
When loading utensils, arrange them in a sloping position
Use rinse aid, if necessary use more (see IM, Rinse aid)
If necessary, adjust the water-softening system to a higher setting (see IM, water-
softening system)
Remind the customer about the Extra Dry programme. (*not available in all
