Water stains on plastic  
parts
Droplet formation on plastic 
surface is physically unavoidable.  
After drying, water stains are  
visible. Use a more intensive programme (more  
water changes). 
Arrange utensils in a sloping position.  
Use rinse aid.
If required, increase softening setting.
Washable or water-soluble  
coatings in the container or  
on the door. Detergent substances are  
deposited. These coatings cannot  
usually be removed with 
chemicals (appliance cleaner, ...). Change detergent brand.  
Clean appliance mechanically.
If there is a “white coating” on  
the container floor, the water  
softening system has been set  
marginally. Increase softening setting and change  
detergent if required.
Salt dispenser cover  1J not 
closed. Close salt dispenser cover correctly.
Only for glasses: Initial glass  
corrosion – can only apparently  
be wiped off. See Glass and utensil damage.
White, stubborn coatings; 
limescale on the utensils,  
container or door. Detergent substances are  
deposited. These coatings cannot  
usually be removed with  
chemicals (appliance cleaner, ...). Change detergent brand. 
Clean appliance mechanically.
Hardness range incorrectly set or  
water hardness greater than  
8.9 mmol/l. Set water softening system according  
to instructions for use or top up salt.
3 in 1 detergent or bio/eco  
detergent not effective enough. Set water softening system according 
to instructions for use or use separate  
detergents (proprietary detergent, salt, rinse  
aid).
Underdosing of detergent. Increase detergent dosage o r change 
detergent.
Too weak rinse programme 
selected. Select a more intensive rinse programme.
Tea or lipstick residue on  
the utensils. Too low rinsing temperature. Select programme with h
igher washing 
temperature.
Too little or unsuitable detergent. Use suitable deterge nt at correct dosage.
Utensils precleaned too intensely;  
sensors therefore decide on  
weak programme sequence. 
Stubborn soiling cannot be  
completely removed. Do not prerinse utensils. Remove only large 
food remnants.  
Recommended programme Eco 50°

brown), difficult to remove  
to non-removable coatings  
in the appliance or on 
stainless steel utensils.
Film formation consisting  
of ingredients from vegetables  
(e.g. cabbage, celery, potatoes,  
noodles, ...) or the tap water (e.g.  
manganese). Can be partly removed with machine  
cleaner or by mechanical cleaning. Coatings  
are harmless.
Film formation caused by metallic  
components on silver or  
aluminium utensils. Can be partly removed with machine  
cleaner or by mechanical cleaning.

detergents (tablets), activate water  
softening system (see chapter Water  
softening system/Special salt)
Plastic parts discoloured. Too low rinsing temperatu re. Select programme with higher washing 
temperature.
Utensils precleaned too intensely;  
sensors therefore decide on 
weak programme sequence.  
Stubborn soiling cannot be  
completely removed. Do not prerinse utensils. Remove only large 
food remnants.  
Recommended programme Eco 50°
Removable streaks on  
glasses, glasses with  
metallic appearance and  
cutlery. Too much rinse aid. Set rinse aid amount to lower setting.

low.
Add rinse aid and check dosage 
(recommended setting 4-5).

Use wash cycle at lower temperature. 
Set water softening system according to the  
water hardness (if required one setting  
lower). 
Use detergent with glass protection  
component.

Rust spots on the cutlery. Cutlery not adequately rust-
resistant. Knife blades are  
frequently more severely  
affected. Use corrosion-resistant cutlery.
Cutlery will also rust if rusting 
parts are rinsed at the same time 
(pan handles, damaged utensil  
baskets, etc.). Do not wash rusting parts.
Salt content in the rinsing water 
too high, as salt dispenser lock  
not fastened firmly or salt was 
spilled while being refilled. Fasten salt dispenser lock firmly or remove  
spilled salt.
The appliance does not  
start. The mains fuse has tripped. Check mains fuse. 
Power cord not inserted. Ensure that the power cord 
is plugged all 
the way into the back of the appliance and  
into the socket. Check that the socket  
functions.
The appliance door has not been 
shut properly. Close the door.

Appliance can be set at the start  
of the programme only. Perform reset (see Terminating  
the programme) and set the appliance  
according to the instructions for use.
The door is difficult 
to open. Child-proof lock is activated. Deactivate childproof lock
. (See instructions 
for use at the back)
Door cannot be closed. Door lock has been activated. Cl ose door with increased force.
Door cannot be closed due to 
installation. Check appliance installation: Door or 
attached parts must close without  
obstruction.
Cover on the detergent 
dispenser cannot be  
closed. Detergent dispenser or cover  
guide blocked by sticky detergent  
residue. Remove detergent residue.
Detergent residue 
in the detergent dispenser  
or in the tablet collecting  
tray. Spray arms blocked by utensils,  
therefore detergent is not rinsed  
out.
Ensure that the spray arms can rotate freely.
The detergent dispenser was  
damp when filled. Pour detergent into the dry detergent 
dispenser only.
