General advice on dishwashing
@ Economical dishwashing:
Collect the dirty dishes and stack them in
your dishwasher. Only select a full wash
programme when both baskets are full.
A rinse and hold programme can be
selected during the day to prevent food soil
from drying on before a full load has been
collected. Always select the programme
according to the degree of soiling (see
chart on pages 14/15).
@ “On glaze” decorations may fade if washed
frequently in the dishwasher over a long
period of time. Check earthenware for
“dishwasher proof’ descriptions.
@ Aluminium articles have a tendency to dis-
colour when machine washed.
@ Some glassware may not be suitable for
machine washing. Etching could occur |
leaving the glasses dull and opaque in
appearance.
@ Clean food residues on silver dishes and
silver cutlery if you do not run a wash pro-
gramme after the meal (some food such as
egg white, egg yolk, mustard, etc., cause
stains and discolouration).
Unsuitable articles:
Wooden chopping boards, heat sensitive
plastic articles, pewter, crockery repaired
with glue, cracked china, old cutlery, steel
knives sensitive to rust, cutlery with wood,
bone, china and mother-of-pearl handles.
If in doubt about an article check with the
manufacturer of the article where possible.
Failing this, wash valuable items by hand.
When buying new china look out for dish-
washer suitable crockery, cutlery and
glasses. Buy articles which have straight
and smooth sides, large openings avoiding
deep indentations on the base of the
crockery.

Safety Information
@ This is a domestic dishwasher for domestic
use only. It must only be used for washing
articles recommended by the manufacturer
for dishwashing by machine and then fol-
lowing the instructions contained in this
booklet. The machine must be installed and
cared for and maintainted as instructed in
this instruction booklet, any installation
instructions and any supplementary
instructions supplied with the machine. Any
other use, installation, maintenance may
lead to damage to the machine, persons or
property for which the manufacturer of the
machine does not accept any responsi-
bility.
Do not stack plastic articles over the heat-
ing element. When stacking lightweight
plastic articles weigh them down with other
heavier items to prevent them from being
shifted and falling on to the heating ele-
ment.
Do not touch the heating element immedia-
tely after a wash cycle is completed.
Only use dishwasher detergents which are
recommended for domestic dishwashers.
Store dishwasher detergents in a safe
place -— away from children. These deter-
gents can cause serious injuries to the
throat or can lead to suffocating when
swallowed. Keep children away from dish-
washers, detergent residues may still be in
the machine.
Do not use any solvents in the dishwasher
— risk of explosion.
The water in the dishwasher is not drinking
water.
Children cannot foresee the consequences
of tampering with electrical appliances.
Do not leave children unsupervised when
machines are in operation.
Children must not play inside the dish-
washer.
Do not sit or stand on the open door of the
dishwasher. The machine may tip over.
The water inlet hose with a plastic con-
tainer at the water feed end contains an
electrical Jead for a valve. Do not cut the
hose. Do not dip this container into water.
In case of a fault, turn off the water supply
tap and switch off the appliance and pull
the plug out of the electrical supply socket.
When this appliance is finally replaced by
a new one, destroy the lock of this
machine, cut off the electrical lead and
dispose of it safely to prevent children
playing with the machine and endangering
their lives.

Setting the water hardness — adding dishwasher salt

Setting the water hardness - adding dishwasher salt
The salt you require is special salt suitable
for domestic dishwashers. On no account
should table salt, cooking salt, road salt or
processed sea salt be used, because they
contain substances adversely affecting the
water softener.
Important! Detergents and salt are very often
available in very similar looking packaging.
Take care that you DO NOT fill the salt con-
tainer with detergent, IT RENDERS THE WATER
SOFTENER INEFFECTIVE. The salt container
filler neck is situated on the right hand side on
the bottom of the wash tub (fig. 2/B). To fill the
container - open the door, lift out the lower
basket, unscrew the cap marked S} and
place the funnel supplied with the machine
over the opening (fig. 5).
Before the first use only, pour 1.5 to 2 litres
(3-4 pints) of water into the salt container.
Then add the salt until it is visible at the top of
the container (capacity approx. 1.5 Kg). During
the filling process, some water is displaced.
Remove any spilled salt from the filler neck
and replace the cap firmly. Replace the lower
basket.
Important!
To prevent salt from entering the washing
cycle close the cap to the salt container firmly.
Cloudy glassware may result from salt getting
into the washing water. No salt residues must
be left on the bottom of the tub. To ensure
that all salt residues are removed, select a
rinse and hold programme or, a complete
wash programme if you have enough dirty
crockery, after the sait container has been
filled.
To replenish the salt container
Replenish the salt container when the lamp
above Symbol SS} on the control panel
(fig. 1/IV) is on.
Please note
For water hardness area 1 - see page 10, no
salt is required and symbol S will light up
every time the machine is switched on. Please
ignore the light in this particular instance — it
does not affect the operation of the machine.
Filling the rinse aid container
Rinse aid is dispensed automatically during
the final hot rinse. it prevents water drops from
clinging to the crockery and gives the final
sparkle to the china and glassware.
Important!
Use only rinse aids suitable for domestic
dishwashers -— we recommend Finish.
Never use normal washing up liquids. These
have high sudsing properties and are unsuit-
able for dishwashers.
You will find the rinse aid container on the
inside of the door (fig. 2/E). Open the contain-
er by turning the lid a quarter turn to the left
(fig. 7/arrow) and slowly pour rinse aid into
the filler neck up to the dotted line (fig. 8).
Replace the. lid and close by turning it clock-
wise. The container will take approx. 150 cc,
which will last for approx. 50 programmes.
Wipe off any spilled rinse aid to prevent
excess foaming during the next wash cycle.
Rinse aid refill indicator
Replenish the rinse aid container when the
level indicator window (fig. 8) shows a dark
dot surrounded by a lighter circle (@)). When
the container is full the window is darker in
colour.
14

Adjusting the rinse aid dosage
The adjuster to alter the quantity of rinse aid
being dispensed is located in the filler neck
(fig. 9). The quantity can be varied from 1-6 cc
and the corresponding numbers are shown
on the adjuster.
To alter the setting, move the arrow to another
setting using a screwdriver or coin.
The machine is set to dispense 3cc rinse aid
(arrow is set to “3”) automatically during the
final rinse. Do not alter the setting unless it
becomes necessary (see page 17/18 “If you
think your machine is not working
properly...”).
Add dishwasher detergent before every wash programme
Before you start a wash programme (except
rinse and hold programme) fill detergent
dispenser with detergent (fig. 2/D). If the
dispenser is closed, push the locking catch
(fig. 10/a) and the lid springs open. The
amount of detergent to use depends on the
degree of soiling of the utensils to be washed.
- For light soiling you will require approx.
20 ml, for normal to heavy soiling approx.
30 ml. When using liquid detergents use
approx. 30 ml and 40 ml respectively. To help
you use the correct amount of detergent the
dispenser is marked “Min” (approx. 20 ml) and
“Max” (approx. 30 mi) (fig. 11). Close the lid of
the dispenser and press uniil it snaps shut.
The detergent is automatically dispensed at
the correct stage of the programme.
We would recommend filling the compartment
in the lid (fig. 10/b) level to the top with deter-
gent for all programmes which include a pre-
wash.
As effectiveness of detergents differs from
one make to another, follow also the recom-
mendations of the detergent manufacturers.
Useful hints:
The “Min” and “Max” markings in the deter-
gent dispenser apply to full loads which is the
most economical way of machine washing.
If you want to wash smaller loads, 15 ml of
detergent (approx. 25 ml liquid detergent) is
sufficient to obtain an excellent wash result.
12
Important!
@ Only use detergents for domestic dish-
washers. Never use washing up liquids
(they cause excessive foaming and the
dishes are not cleaned).
@ Always close the detergent pack and store
in a dry piace (lumpy detergent has lost |
its cleaning power).
@ Always use the recommended amount of
detergent.
If you use too little, starch deposits will
remain on the dishes which can only be
rubbed off by hand.
There are two types of dishwasher detergents
on the market, the conventional type and the
ultra compact cleaners.
When using an ultra compact cleaner we
recommend you select a BIO 50°C pro-
gramme. This BIO programme was specially
developed for the compact cleaners.
The cleaning effect of the Universal BIO 50°C
or the Economy 50°C BIO programme using
ultra compact cleaners can be compared to
using the Universal 65°C or Economy 65°C
programme with conventional detergents. The
BIO programme has the added benefit that
your crockery is treated in a gentler fashion
due to the lower wash temperature and the
absence of corrosive substances.

Loading the machine
Before you load the machine remove any
remaining food and bones from the plates and
soak saucepans with burnt on food as you
would when washing up by hand. The easiest
way to load a basket is from back to front.
Lower basket (fig. 12):
Large heavily soiled dishes are best cleaned
in the lower basket. Pull out the lower basket
as far as the stops and stack it with large
items: plates, serving dishes, serving plates
and saucepans as illustrated.
Cutlery basket:
Arrange the cutlery as follow:
@ Distribute the unsorted cutlery loosely in all
basket compartments so that each item is
reached by the wash water.
@ Knife, fork and spoon handles down for
best results.
@ Make sure spoons and forks do not stick
together. Use the special holder for tea and
coffee spoons.
@ Lay long handled utensils such as a soup
ladle flat in the top basket to avoid block-
ing the upper spray arm.
Top basket (fig. 13):
Smaller, more fragile items are washed gently
in the top basket. Pull out the top basket as
far as the stop to arrange the smaller items
such as saucers, cups and glasses as illus-
trated. You can also use the fold down racks
to load extra cups.
Important!
By arranging the dishes correctly you will
ensure a satisfactory wash result.
@ Stack cups, glasses, saucepans, etc.,
upside down so that the water can run off
freely.
@ Thick and curved plates and similiar items
should be placed in the bottom basket on
the left where the racks are wider so that
each item is reached by the wash water.
@ Bowls, saucepans and frying pans are well
positioned upside down over the short
racks in the lower basket.
@ Load glasses so that they do not touch
each other (to prevent stains and break-
ages).
@ When stacking items under the folding
racks in the upper basket make sure that
the water sprays can reach both layers.
Top basket — height adjustment
The height of the top basket is adjustable.
Top basket in top position: Loading height in
top basket: 20 cm, lower basket: 29 cm.
Top basket in lower position: Loading height
in top basket: 25 cm, lower basket: 24 cm.
The top basket has been slotted into the top
position at the factory. If you wish to adjust the
height of the top basket proceed as follows:
1. Pull the top basket forward to the stop
position.
2. Remove the basket retainers (fig. 14) at the
front of the basket rails.
3. Remove the basket from the machine.
4. Insert the upper or the lower rollers into the
rails (upper rollers = lower position of top
basket, lower rollers = top position of top
basket).
5. Refit the basket retainers.

Switching on
(programme chart - see previous page)
1. Fully open the water tap.
Important: If the dishwasher was started
but the water tap had not been opened,
switch off the machine, fully open the
water tap, switch on the machine and
start the programme again.
2. Turn the start/indicator switch (fig. 1/IIb
clockwise to symbol A or B.
3. Press the on button and the programme
button required (fig. 1/1).
The machine “on” light is on and the red
programme indicator above the selected
programme is also on. The programme
starts.
Programme correction
If you have selected the wrong programme by
mistake, simply turn the start/indicator switch
to the correct setting and/or press the correct
programme button.
Programme sequence indicator (fig. 1/III)
After the machine has been started the pro-
gramme indicator passes through the various
stages automatically, indicating each stage
reached as it turns.
The indicator stops temporarily during the
wash and the final rinse until the water has
reached the required temperature.
Warning! Before turning the start/indicator
switch, switch off the machine to prevent det-
ergent being released into the machine by
mistake. The machine should also be switched
off due to radio interference suppression
requirements.
Switching off - unloading the machine
The dishwasher switches off automatically
when the programme is finished.
@ Press the off button. The machine “on” light
goes out.
@ Wait approx. 15 minutes before unloading
the machine to allow everything to dry
completely. If the crockery is not removed
at that stage, open the dishwasher door
and leave it slightly ajar. To speed up the
drying phase, you can open the door com-
pletely and then leave it slightly ajar (steam
will escape from the machine). This is only
recommended if the underside of your
worktop has been protected with the alu-
minium foil strip supplied with the machine.
@ Empty the lower basket first and then the
upper basket. This prevents any water
which may have collected in recessed or
curved items in the upper basket from
dripping onto crockery in the lower basket.
16
@ Check the filters after every programme. If
they are dirty clean them as per instruc-
tions on page 17.

Cleaning the filters
Coarse filter (fig. 15)
Remove the coarse filter and brush it clean
under running water. Check the lower half of
this filter also and remove the food residues
which may be trapped there. Note that the
upper cylindrical section of the coarse filter
can be lifted out (fig. 16).
When replacing ensure that the upper section
sits straight and tight before re-inserting the
coarse filter.
Fine filter (fig. 17)
Clean the fine filter (a) and microfilter (b) as
and when necessary. To remove the fine filter
turn it anticlockwise. Clean it thoroughly. When
replacing the fine filter make sure that the
edge of the filter forms a proper seal with the
bottom of the tub. Then turn it clockwise.
Never carry out a wash programme without
a filter.
Maintenance
Fascia panels and controls must not be
cleaned with abrasive cleaning materials or
furniture polish. Should cleaning be necessary
use lukewarm water only.
If you think your machine is not working properly
Before you call out a service engineer check the following points carefully, it will save you the cost
of the engineer calling on you.
A continuous hum can be heard?
(even when the machine is switched off)
@ The anti-flood system has been activated
(see page 22).
@ First close the water tap, then switch off at
the power socket and remove the plug.
@ To rectify the problem, call AEG Service.
The programme does not start?
@ Are the fuses in working order?
@ \|s the door closed properly?
(There is a short pause after the machine
has filled with water!)
The machine is not taking in any water?
@ Have you turned on the tap?
@ Check the water inlet hose (it must not be
kinked).
The start/indicator switch stops at the begin-
ning of the wash (Il ) or final rinse (3,2
cycle?
@ Have you opened the water tap fully?
(See page 16.)
@ ls the filter in the inlet hose blocked? The
filter is located where the hose attaches to
the tap. Unscrew the hose and clean the
filter under running water.
@ Check the water pressure. It must be at
least 1 bar (15 Ib/sq. inch) - see page 21/22.
The dishes are not clean?
@ Did you select the correct programme?
The programme has to be chosen accord-
ing to the degree of soiling.
@ Did you stack the dishes according to our
recommendations? The water sprays must
have access to the dishes from all sides —
the baskets must not be overloaded.
@ Were the spray arms able to rotate freely?
When the upper spray arm is stationery it
rests at an angle to allow the remaining
water to drain off at the end of a pro-
gramme. During the programme it will auto-
matically return to a horizontal position.
@ Are the filters clean? Have you inserted the
filters properly after cleaning?
@ Did you use the correct amount of deter-
gent?
@ Check that the drain hose has been
installed according to our instructions on
page 21/22.
17

If you think your machine is not working properly
@ Ifthe machine is connected to a hot fill
supply (max. 60°C) — only economical if
hot water is available “nearly free of
charge” - do not use 50°C programmes to
allow detergent sufficient time to work.
@ Did you top up the salt container? If the
water hardness in your area is over
10 degrees and your dishwasher is operat-
ed without salt, the result may be affected
adversley and white and yellow chalk
deposits will remain on your dishes.
@ Did you select the correct degree of water
hardness according to the information of
your local Water Authority? (See also
page 10.)
The dishes are not dry and sparkling?
@ Did you use a rinse aid recommended
by us?
@ Did you fill up the rinse aid container?
@ |s the correct quantity of rinse aid being
dispensed?
Overdosing of rinse aid:
If too much rinse aid is used opaque or bluish
smears will apear. Reduce the output.
Underdosing of rinse aid:
if too little rinse aid is used white/grey dried-on
water marks will appear. Increase the output.
There are rust spots in the machine?
@ The stainless steel tub, the inner door and
the filters cannot rust. If you find rust spots,
these are introduced with the water or due
to rust on cutlerly, saucepans, etc. Did you
select a rinse and hold programme or a
complete wash programme after filling the
salt container? Remove such stains with a
stainless steel cleaner.
Symbol S>5 is illuminated
@ Unless you live in water hardness area 1,
the salt container needs to be replenished.
For water hardness area 1 the light will be
on every time the machine is switched on.
No salt is required for water hardness
area 1 - see page 10.

Information for the installer
Installation
The appliance must stand level and on a firm
floor. The floor should be clean and free from
floor polish and grease. The appliance has
adjustable feet. If necessary adjust feet.
Should a freestanding machine be built under
a worktop in a built-in kitchen, the table top of
the machine can be removed. In this case you
need to protect the underside of your kitchen
furniture worktop at the front with an aluminium
foil strip which is available as an optional extra
from AEG Spare Parts Department. You will
find details how to secure the aluminium foil
strip on the-back of the strip. This is the only
way your worktop will be protected against
steam being emitted when the dishwasher
door is opened.
Water supply
This dishwasher is equipped with an anti-
flood device to be fitted to the water tap —
AQUA-LOCK (see also page 22). To ensure
the correct operation of this anti-flood device
it is imperative that the double-skin inlet hose
is connected to the water supply in a particu-
lar way.
Please see separate installation instructions
supplied with the machine.
To protect the drinking water supply system
your dishwasher is fitted with an anti-syphon.
A connection to a hot water supply up to a
maximum of 60°C with.a minimum pressure of
{1 bar is possible, although the machine must
not be connected to single outlet instantane-
ous electric or gas heaters.
Please ensure you comply with the drinking
water regulations of your local Water Board.
The high pressure hose with 34” hose
coupling complete with sealing washers is
supplied. We recommend not to use other
washers which may be of inferior quality. It is
sufficient to tighten the nuts by hand.
The machine may be connected:
a) directly to a tap with 34” BSP thread
termination
b) to a T-junction on your existing tap, or
preferably
To comply with Safety Regulations, the
machine must be installed in such a way that
there is no access to live parts or internal
connections with functional insulation.
Please note
(this applies to free-standing appliances with
worktop only)
Should a dishwasher be installed next to a
gas, solid fuel or electric cooker due to lack of
space, a heat insulating panel (85 x 57.5 cm)
has to be fitted, the side facing the cooker has
to be lined with aluminium foil.
c) to a completely seperate water supply in
order to avoid interference with the kitchen
water supply during operation of the
machine.
Minimum water pressure: approx. 1 bar pres-
sure above atmospheric pressure (1 atu =
approx. 1 kp/cm? = approx. 10 N/cm2. For less
than one bar of pressure above atmospheric
pressure, consult the AEG Technical Depart-
ment. Maximum permissible water pressure:
approx. 10 bars. For over 10 bars excess
pressure, connect a pressure relief valve
(obtainable through your installer).
If a longer water supply hose is needed it
should be a single run of high pressure hose
available in one length from AEG Spare Parts
Department. Never add extensions to hoses.
Turn off the water tap if the machine is not in
use. A rigid copper pipe connection (diameter
8-10 mm) can be used as extensions for
machines fitted with AQUA-LOCK.
