Water softener
In order to rinse dishes and glasses
satisfactorily, the dishwasher requires soft
water, i.e. containing little or no lime,
otherwise water stains will be left behind
on crockery and glasses, etc.
If the tap water exceeds a certain level of
hardness, it must be softened, i.e.
decalcified, so that it can be used in the
dishwasher.
This is achieved by adding a special salt
to the water softener inside the
dishwasher.
The water softener, that is the required
amount of salt, is set up according to how
hard the tap water is.
Setting up the water softener
Determine the level of hardness of your
tap water. Your local water company or
service agent can help you with this.
Identify setting from the following water
hardness table.
Water hardness table
Close the door.
Hold down programme button Band
press 1main switch until the digital
display illuminates, then release the
buttons.
The LED for button Bflashes and
the digital display displays the factory
setting .
To change the setting,
press programme button B .
Each time the button is pressed, the set
value increases by 1; after , the
setting goes back to .
Switch off the main switch 1. The
chosen setting has now been stored.

Filling the special salt
container
How the salt works
While washing is taking place, salt is
automatically rinsed out of the salt
container into the water softener where it
dissolves the lime in the water.
The dissolved lime is pumped out of the
dishwasher. The water softening system is
then ready for the next load.
This process of regeneration can only
function when the salt is dissolved in
water.
Unscrew the lid on the salt container 24 .
Before you use the dishwasher for the first
time, pour approx. 1 litre of water into the
salt container.
Use the enclosed salt filler.
Refill with salt (do not use edible salt)
until the salt dispenser is full (max. 1.5 kg).
When the salt dispenser is being refilled,
water is displaced and drains away.
Therefore always refill the salt dispenser
immediately before switching on the
dishwasher (to prevent corrosion). As a
result, the overflowing salt solution will be
immediately diluted and rinsed out. Then
remove salt residue from the filler area and
screw on the dispenser cover, ensuring
that it is not fitted askew.
The LOW SALT indicator 8on the front
panel will light up initially but will extinguish
again after a short period when the salt
solution has become sufficiently
concentrated.
Note
When the control is set to , it
is not necessary to fill up with salt
as none will be consumed while
the dishwasher is operating. The
LOW SALT indicator is switched
off. If the control is set between
and , then salt must
be added to the dispenser.
Do not pour detergent into the
container for special salt. This
would destroy the water
softener.
Salt refill indicator
As soon as the salt refill indicator 8is lit
on the control panel, refill with salt
immediately before the next rinse cycle.

en
9
Filling the rinse-aid
container
The purpose of a rinse-aid is to prevent
the formation of water marks on tableware
and utensils, and to ensure that glasses
are clean and sparkling. The rinse-aid is
consumed during the washing process.
Fold back the lid on the rinse-aid
container 29 .
To open the lid, press the mark on
the rinse-aid lid and simultaneously lift
the lid off the lug .
Pour the rinse-aid into the filler hole
until the level indicator turns dark.
Close the lid, ensuring that you hear it
snap closed.
Note
Use only rinse aid for domestic
dishwashers. Spilt rinse aid
may result in excessive foam
formation in the next rinse
cycle. Therefore, remove any
spilt rinse aid with a cloth.
Adjusting the amount of
rinse-aid
The amount of rinse-aid added to the
water can be varied by adjusting the
stepless control. The rinse-aid control has
been set to ”4” in the factory.
Do not alter the setting of the rinse-aid
control unless streaks (turn knob towards
”–”) or water marks (turn knob towards ”+”)
are left on the dishes.

Note
Do not switch off the rinse-aid
indicator unless you are using
detergent products with an
integrated rinse-aid!
Unsuitable dishes
You should not clean the
following items in your
dishwasher:
Cutlery and dishes made of wood. They
will leach out and become unsightly; the
utilised adhesives are also not suitable
for the dishwasher temperatures.
Delicate décor glasses, craft dishes and
vases, special antique or irreplaceable
dishes. These décor items are not
dishwasher-safe.
Plastic parts, copper and tin dishes
sensitive to hot water are not suitable
either. Overglazed patterns, aluminium
and silver parts tend to become
discoloured and fade during the rinsing
cycle. Even some types of glass (e.g.
crystal glass objects) may become cloudy
after many rinse cycles. Completely
absorbent materials, such as sponges and
cloths must not be cleaned in the
dishwasher either.
Recommendation:
In future buy only dishes which are
identified as dishwasher-safe.
Note
Dishes which are soiled with
ash, wax, lubricating grease or
ink must not be cleaned in the
dishwasher.

en
11
Damage to glassware and other
dishes
Possible causes:
type of glass or manufacturing process
chemical composition of detergent
water temperature and duration of
dishwasher programme.
Suggested remedy:
Use glassware or porcelain dishes that
have been marked ’dishwasher–proof’
by the manufacturer.
Use a mild detergent that is described
as ’kind to dishes’. If necessary, seek
further information from detergent
manufacturers.
Select a programme with as low a
temperature and as short a duration as
possible.
To prevent damage, take glass and
cutlery out of the dishwasher as soon
as possible after the programme has
ended.
Arranging crockery, glasses,
etc. in the dishwasher
Loading the dishwasher
Scrape off any large amounts of left-over
food. It is not necessary to rinse the dishes
under running water.
Place objects in the dishwasher in such a
way that
items such as cups, glasses, pots/pans,
etc. are stood upside down,
curved items, or those with recesses,
should be at a slant so that water can
run off,
they are stacked securely and cannot
tip over,
they do not prevent the spray arms from
rotating while washing takes place.
Very small items should not be washed in
the dishwasher as they could easily fall out
of the baskets.
Removing the dishes
To prevent water dripping from the top
basket onto the dishes in the lower basket,
we recommend that you empty the lower
basket first and then the top basket.

Cutlery
Cutlery should be placed in the
dishwasher always unsorted and with the
eating surface pointing downwards. The
spray jet is then better able to reach the
individual parts.
To prevent injuries, place long, pointed
accessories and knives on the étagère
(some models) or on the knife shelf
(available as an accessory).
Folding spikes *
* on applicable models
To improve stacking of pots and pans, the
spikes can be folded down.
Baking sheet spray head *
* some models
You can clean large baking sheets or
grilles with the baking sheet spray head.
To do this, remove the top basket and
insert the spray head as illustrated in the
diagram.
To ensure that the spray jet can reach all
parts, arrange the baking sheets as
illustrated
(max. 4 baking sheets and 2 grilles).

en
13
Shelf *
* not on all models
Lean tall glasses and those with long
stems against the shelf – not against other
items to be washed.
Long items, serving cutlery, salad servers
or knives should be placed on the shelf so
that they do not obstruct the rotation of the
spray arms. The shelf can be folded back
when not required for use.

If required, the height of the top basket can
be adjusted in order to create more space
for large utensils either in the top or bottom
basket.
Select one of the two following procedures
according to the design of the top basket
for your appliance model:
Top basket with upper
and lower roller pairs
Pull out the top basket.
Remove the top basket and re-attach it
to the upper or lower rollers.

Top basket with side levers
(Rackmatic)
Pull out the top basket.
To lower the basket, press in
succession the two levers on the left
and right sides of the basket. Always
take hold of the side of the basket on
the upper edge, otherwise the basket
will not drop smoothly (and may
damage the utensils).
To raise the basket, take hold of the
basket on the upper edge and pull
upwards.
Before you re-insert the basket, ensure
that it is at the same height on both
sides. Otherwise, the appliance door
cannot be closed and the upper spray
arm will not connect to the water circuit.

Detergents
Information about detergents
You can use any brand of liquid or powder
detergent, as well as tablets, that have
been specifically designed for use in
domestic dishwashers. (Do not use normal
washing-up liquid!)
Nowadays there are three types of
dishwasher detergent available:
1. those containing phosphates and
chlorine,
2. those containing phosphates but no
chlorine,
3. those containing neither phosphates
nor chlorine.
When a phosphate-free detergent is used
in conjunction with hard water, there is a
greater possibility that white marks will be
left behind on crockery and glasses, etc.
These can be avoided by pouring an
increased amount of detergent into the
dispenser.
Chlorine-free detergents have a reduced
bleaching effect. This can mean that tea
stains are not completely removed or
plastic items become discoloured.
This can be resolved by:
– selecting a higher temperature
programme, or
– increasing the amount of detergent, or
– using a detergent that contains chlorine.
Check the label on the detergent
packaging to determine whether a
particular product is suitable for use with
silverware.
If you have any further questions, we
recommend that you contact the customer
advice departments of the various
detergent manufacturers.
Detergent compartment with
measuring marks
The side of the detergent compartment is
marked with lines to help you determine
how much powder to add.
The capacity of the detergent container is
15 ml up to the bottom line and 25 ml up to
the middle line. When the compartment is
full it contains 40 ml.
40 ml
25 ml
15 ml
Important
If the lid on the detergent com-
partment is closed, press the
release lever to open the flap.
Adding detergent
Tip detergent powder into the
corresponding compartment 30 .
Please observe the manufacturer’s
instructions printed on the detergent
packaging when determining the
correct dosage.
Due to the different solvency properties
of the detergent tablets supplied by
various manufacturers, the cleaning
efficiency of the detergent may not be
fully utilised by short programmes. It is
recommended to use washing powder
for these programmes.
When you select the INTENSIVE
programme, tip an extra 10–15 ml of
detergent onto the inside surface of the
door.

en
16
Reduce costs!
If your dishes are only
moderately dirty, you may be
able to use less detergent than
recommended.
Close the lid on the detergent
compartment.
Press down the lid (1) until it clicks
shut (2).
If you are using detergent in tablet form,
read the manufacturer’s
recommendations on the packaging in
order to
determine where the tablets should be
placed inside the dishwasher (e.g. in
cutlery basket, detergent compartment,
etc.).
Make sure that the lid on the detergent
compartment is closed, even if you are
using tablets.
auto 3in1
The use of so-called combined detergent
products may make the use of rinse aid
and/or salt unnecessary.
There are currently several types of
combined detergent products available.
3in1: They contain detergent, rinse aid
and salt function.
2in1: They contain detergent and rinse
aid or salt function.
>>> Always check the type of detergent
or combined product which you
are using!
Always follow the operating instructions
or the information on the packaging.
The rinse programme is automatically
adjusted in order to obtain the best
possible rinsing and drying result.
Observe the following important
information if using combined cleaning
products:
Regeneration salt is not required up to
a water hardness of 21dH (37fH,
26Clarke, 3.7 mmol/l) only. No other
settings on the appliance are required.
Salt is still required if the water
hardness is above 21dH (37fH,
26Clarke, 3.7 mmol/l). Fill the salt
dispenser with salt 24 and select
setting 6 on the water softening system.
If in doubt, please contact the detergent
manufacturer, especially if:
the utensils are very wet at the end
of the programme.
limescale forms.

en
17
Note
Optimum rinsing and drying results can be
obtained by using standard detergents in
conjunction with separate application of
salt and rinse aid.
Observance of the operating instructions
or information on the packaging of the
combined detergents determines their
effectiveness.
Note
Even if the rinse aid and/or salt refill
indicator is lit, the rinse programme runs
correctly when 3in1 products are used.
If the rinse aid refill indicator 9or salt
refill 8indicator is defective and you
would like to switch it off, proceed as
follows:
Switching the rinse aid refill
indicator off and on
You can switch the rinse aid refill indicator
9on or off. This function can be

The set value is stored within the
device.
Approx. 4 litres of water are required to
regenerate the water softening system.
As a result, the water consumption per
rinse cycle increases by 0 to maximum
4 litres depending on the water hardness
setting.
Note
If you use the detergent and rinse aid
separately or switch from combined
detergents to standard cleaning products,
ensure that the rinse aid refill indicator has
been switched on and the water softening
system has been set to the correct water
hardness.

Washing dishes
Reduce costs!
If only a small number of
dishes have been loaded into
the dishwasher, selecting a
programme that operates at
the next lowest temperature
will usually suffice.
Programme specifications
The programme specifications can be
found in the summary of instructions.
Programme specifications refer to normal
conditions. Greater deviations may occur
due to:
varying amounts of dishes
water supply temperature
water pipe pressure
ambient temperature
mains voltage tolerances
and the tolerances specific
to the appliance (e.g. temperature,
amount of water, etc.)
The water consumption values refer
to a set water hardness value of 4.
Aqua sensor *
* on applicable models
The Aqua sensor is an optical measuring
device which measures the turbidity of the
rinsing water. A light barrier can detect
dissolved food remnants in the water, e.g.
egg, fat and oats.
The Aqua sensor is used according to
the programme. When the Aqua sensor
is active, ”clean” rinsing water may be
transferred into the next rinsing bath
and/or the temperature adjusted. If the
turbidity is greater, the water is drained
and is replaced with fresh water. In this
way the water consumption is reduced by
approx. 4 litres for utensils which are ”less”
dirty.
Switching the dishwasher ON
Turn on the tap.
Set main switch 1to ON.
