Fault
Water stains on plastic parts.
Washable or water-soluble
coatings in the container or on
the door.
White, stubborn coatings;
limescale on the dishes,
container or door.
Tea or lipstick residue on the
dishes.
Colored (blue, yellow, brown),
difficult to remove to non-
removable coatings in the
appliance or on stainless steel
dishes.
Colored (yellow, orange, brown),
easily removable deposits inside
the appliance (mainly in the floor
area)
Discoloration of the plastic parts
inside the appliance.
Cause
Droplet formation on plastic surface
is physically unavoidable. After
drying, water stains are visible.
Detergent substances are deposited.
These coatings cannot usually be
removed with chemicals (appliance
cleaner, ...).
If there is a "white coating" on the
container floor, the water softening
system has been set very low.
Salt dispenser cover 1R not closed. Close salt dispenser cover correctly.
Only for glasses: Initial glass
corrosion – can only apparently be
wiped off.
Detergent substances are deposited.
These coatings cannot usually be
removed with chemicals (appliance
cleaner, ...).
Hardness range incorrectly set or
water hardness greater than
8.9 mmol/l.
3 in 1 detergent or bio/eco detergent
not effective enough.
Underdosing of detergent.
Too weak rinse cycle selected.
Too low rinsing temperature.
Too little or unsuitable detergent.
Dishes precleaned too intensely;
sensors therefore decide on weak
wash cycle sequence. Stubborn
soiling cannot be completely
removed.
Film formation consisting of
ingredients from vegetables (e.g.
cabbage, celery, potatoes, noodles,
...) or the tap water (e.g. manganese).
Film formation caused by metallic
components on silver or aluminum
silverware.
Film formation consisting of
ingredients from food soils and
substances from the tap water
(limescale), "soapy"
Plastic parts inside the appliance may
become discolored during the
service life of the dishwasher.
Troubleshooting

Increase softening setting and change
detergent if required.
See "Glass and silverware damage".
Change detergent brand.
Clean appliance mechanically.
Set water softening system according to
instructions for use or top up salt.

instructions for use or use separate
detergents (proprietary detergent, salt,
rinse aid).
Increase detergent dosage or change
detergent.
Select a more intensive rinse cycle.
Select wash cycle with higher washing
temperature.
Use suitable detergent at correct dosage.
Do not prerinse dishes. Remove only large
food soils.
Increase sensitivity of the sensors.
Recommended wash cycle "Regular"
Can be partly removed with machine cleaner
or by mechanical cleaning. Coatings are
harmless.
Can be partly removed with machine cleaner
or by mechanical cleaning.
Check function of the water softening
system (refill with salt) or, if using combined
detergents (tablets), activate water
softening system.
Discoloration is normal and will not impair
the function of the dishwasher.
