Programme data 
The programme data (consumption  
values) can be found in the summary of  
instructions. They refer to normal  
conditions and the water hardness set  
value  •:‹… . Different influencing factors 
such as e.g. water temperature or line  
pressure may result in deviations.
Aq u
a s ens
orAqua sensor *
* depending on model 
The Aqua sensor is an optical  
measuring device (light barrier) which 
measures the turbidity of the rinsing  
water. 
The Aqua sensor is used according to  
the programme. If the Aqua sensor is  
active, “clean” rinsing water can be  
transferred to the next rinse bath and  
water consumption can be reduced by  
3–6 litres. If the turbidity is greater, the  
water is drained and is replaced with  
fresh water. In the automatic  
programmes the temperature and  
running time can also be adjusted to the  
degree of soiling. 
Switching on the appliance 
1. Turn on the tap fully.
2. Switch on ON/OFF switch (. 
The Eco 50° programme display  
flashes. This programme remains  
selected if no other programme  
button 0 is pressed. The expected 
programme duration  
flashes on the digital display ).
3. Press the START button P. 
The programme starts running. Note 
- for environmentally friendly operation  
of the dishwasher:
For ecological reasons the Eco 50°  
programme is preset whenever the  
appliance starts. This conserves 
environmental resources and not least  
saves you money. 
The Eco 50° programme is a 
particularly environmentally friendly  
programme. According to EU  
regulation 1016/2010 it is the 
“Standard programme” which is the  
most efficient standard cleaning cycle  
for cleaning normally soiled utensils in  
terms of the combined energy and  
water consumption for cleaning these  
types of utensils.
Remaining running time  
display 
When the programme is selected, the  
remaining running time of the  
programme is indicated on the digital  
display  ). 
The running time is determined during 
the programme by the water  
temperature, the number of utensils as  
well as the degree of soiling and may  
vary (depending on the selected  
programme).

Filters 
The filters 
1R keep large foreign 
objects in the rinsing water away from  
the pump. These foreign objects may  
occasionally block the filters. 
The filter system consists of a coarse  
filter, a flat fine filter and a microfilter. 
1. After each washing cycle check the  
filters for residue.
2. Unscrew filter cylinder as illustrated  
and take out filter system.
3. Remove any residue and clean filters 
under running water.
4. Re-install filter system in reverse  
sequence and ensure that the arrow  
marks are opposite each other after  
closing the filter system. Spray arms 
Limescale and contaminants in the  
rinsing water may block nozzles and  
bearings on the spray arms 
1: and 
1B .
1. Check outlet nozzles on the spray  
arms for blockages.
2. Unscrew the upper spray arm  1:.
3. Remove the lower spray arm  1B 
upwards.
4. Clean spray arms under running 
water.
5. Re-engage or screw on spray arms.

3 Fault, what to do?Fault, what to do?
Experience has shown that you can  
rectify most faults which occur in daily  
operation yourself. This ensures that  
the machine is quickly available to you  
again. In the following overview you can  
find possible causes of malfunctions  
and helpful information for rectifying  
them. 
Note 
If the appliance stops during  
dishwashing or does not start for no  
obvious reason, first run the Abort  
programme function (Reset).  
(See chapter entitled “Operating  
the appliance”) ãWarning –  Don’t forget: Repairs may 
be carried out by technicians only. If a  
component has to be replaced, ensure  
that only original spare parts are used.  
Improper repairs or use of non-original 
spare parts may cause considerable  
damage and put the user at  
considerable risk. 
Waste water pump 
Large food remnants or foreign objects  
which were not captured by the filters  
may block the waste water pump. The  
rinsing water will then be above the filter.  In this case: 
1.
First always disconnect the  
appliance from the power supply.
2. Take out top basket  1 and bottom 
basket  1b.
3. Remove the filters  1R.
4. Scoop out water, use a sponge if  
required.
5. Prise out the white pump cover  
(as illustrated) using a spoon. Grip  
the cover on the crosspiece and lift  
diagonally inwards. Remove cover  
completely.
6. Check impeller wheel and remove  
any foreign objects.
7. Place cover in the original position  
and press down until it engages  
(click).
8. Install filters.
9. Re-insert baskets.

Overview of programmes, Programme  
sequence).
Water collecting in depressions 
on the utensils and cutlery. Arrange utensils in a sloping position, 
arrange affected utensils as sloping  
as possible.
The combined detergent used 
has a poor drying performance. Use different combination detergent with 
better drying performance. Use of rinse aid  
also increases the drying performance.
Intensive drying to increase

Utensils were removed too early 
or drying process had not ended  
yet. Wait until program ends or wait until 30 min  
after program ends before removing  
utensils.
The eco rinse aid used has a poor 
drying performance. Use a proprietary rinse aid. Eco products are 
much less effective.
Plastic utensils not dry. Special properties of plastic. P lastic has a lower heat storage capacity 
and therefore dries less well.
Cutlery not dry. Cutlery not arranged properly  in the cutlery basket. Separate cutlery if possible, prevent contact  
points.
Cutlery not arranged properly  
in the cutlery drawer. Arrange cutlery properly and separate if 
possible.
Appliance interior wet after 
rinse cycle. No appliance fault. On account of the “Condensation drying
” 
principle, water droplets are physically  
induced and required in the container. The  
humidity in the air condenses on the inner  
walls of the dishwasher, drains and is  
pumped out.
