Installation
Positioning
After removing the outer carton, set up
the machine in the selected spot,
preferably very close to water loading and
draining facilities. Furthermore, the
machine can be installed with the sides
and back in touch with the adjacent
furniture or with the wall.
The dishwasher features fill and drain
hoses which can be turned either to the
right or to the left (fig. 1) to suit the
installation.
The machine can be installed under the
kitchen counter or under the sink (see
page 29).
Levelling
The machine should be accurately
levelled by adjusting the levelling feet so
that it be perfectly level (max. allowed
error + 29). An accurate levelling is a must
to ensure a correct operation of the
machine.

Water supply connections
This Zanussi dishwasher may be
connected to either a hot or cold water
supply, and for convenience, it is well
worth having it permanently «plumbed
in». Just make sure that the water
pressure is within the limits given in the
technical data, and, in the case of a hot
water supply, that the temperature never
exceeds 60°C (140 °F).
Your local Water Authority will advise you
on the average mains pressure in your
area. Where the water is supplied via a
cold water storage cistern, or hot water
cylinder, you can work out the pressure
yourself in both cases by measuring the
vertical distance (or «head») between the
machine's inlet hose, and the outlet from
the cold water storage cistern; allowing
roughly 1 psi for every 2 feet.
As to the making of the connection itself,
the coupling nut fitted to the machine's
supply hose is designed to screw onto
either a 3/4 inch gas thread spout, or to a
purpose made quick-coupling tap such as
the Press-Block.
To make this easier, the hose itself may be
turned to the right or left. In either case,
be sure to incorporate the strainer
supplied with the machine onto the joint
(fig. 2).

Waste connections
Care must also be taken over the disposal
of the waste water from the machine. If
your dishwasher is not to be permanently
«plumbed in», merely hook the curved end
of the drain hose firmly over the edge of
the kitchen sink, having made sure that
the sink is empty, and that the waste
outlet is not blocked.
Otherwise, fit a P-trap and stand-pipe
assembly like that in figure 3 (ensure the
pipe has an internal diameter of at least
38 mm (1% ins), and hook the drain hose
into that). In this case ensure that there is
an air gap between the hose and the
inside of the pipe to prevent the risk of
dirty water being syphoned back into the
machine, and check that the top of the
stand-pipe is between 300 and 900 mm
above floor level. In addition, make sure
that the stand-pipe/trap assembly
discharges into the same soil system as
the kitchen sink.
300mm min
900mm max
There are just two other points to bear in
mind. Firstly, with the machine in its
permanent position, do check that the
drain hose is not kinked, or squashed in
such a way as to obstruct the flow of
water. Secondly, if the drain hose supplied
with the machine is not long enough to
reach the desired discharge point, it can
be replaced with a hose of the same
internal diameter, up to 2 m long (see your
local Service Network or installer).

Electrical connections
WARNING: THIS APPLIANCE MUST
BE EARTHED. The manufacturer
declines any liability should this safety
measure not be observed.
If the plug that is fitted to your appliance
is not suitable for your socket outlet, it
must be cut off and the appropriate plug
fitted.
The cut off plug should be disposed of to
prevent the hazard of electric shocks in
case it should be plugged into a 13 Amp
socket in another part of your home.
IMPORTANT: The wires in this mains
lead are coloured in accordance with the
following code:
GREEN AND YELLOW - EARTH
BLUE - NEUTRAL
BROWN - LIVE
If you fit your own plug, the colours of the
‘wires in the mains lead of your appliance
may not correspond with the markings
identifying the terminals in your plug, this
is what you have to do:
Connect the green and yellow (earth) wire
to the terminal in the plug which is
marked with the letter «E» or the earth
simbol ©), or coloured green, or green and
yellow.
Connect the blue (neutral) wire to the
terminal in the plug which is marked with
the letter «N» or coloured black.
Connect the brown (live) wire to the
terminal which is marked with the letter
«L» or coloured red.
The plug moulded on to the cord
incorporates a fuse. For replacement use a
13 Amp BS 1362 fuse. Only ASTA
approved fuses should be used.
The fuse cover/carrier must be replaced
in the event of changing fuse.
The right fuse cover/carrier colour is the
one shown by the coloured insert at the
base of the plug or is the colour of the
inscription at the base of the plug.
The plug must not be used if the fuse
cover/carrier is lost.
A replacement cover/carrier must be
obtained from Zanussi Service Agents
whose addresses are listed on the
attached «Zanussi Service and Spares
Nationwide».
THIS APPLIANCE COMPLIES WITH
E.E.C. DIRECTIVE NO. 82/499 OF 7.6.82

Using your machine
Open the machine by pulling the handle
outwards.
To close the door push it back until you
feel it click.
Water Softening
The dishwasher has a completely
automatic water softener. All you need to
do is to fill the container with salt and
then recharge it with more salt.
The water softener prevents limestone
and mineral salts, present in water to
varying degrees, depositing on crockery
and forming whitish marks which make
the crockery look dull.
Softened water improves the cleaning
action, and after rinsing, the crockery and
glass should look clean and shining.
Filling the Salt Container
Important
When the machine is new carry out one
complete wash cycle before filling the salt
container with salt.
To fill the container, unscrew the cap
(fig. 4) and using the funnel supplied with
the machine pour 1.5 Kg (31b) coarse salt
into it.
Replace the cap making sure that there is
no trace of salt on the thread of the screw
or on the gasket. Screw the cap on tightly.
Important
Use only coarse salt (which is often
available from garden centres) or salt sold
specifically for dishwashers.
Always refill the container immediately
before starting a complete wash cycle,
(not before Rinse and Hold) so that any
salt granules or salt water which may flow
out of the container (which will always
have some water in it) during the refilling
will not remain on the bottom of the tub
without being properly diluted.
11

Adjusting the Water Softener
The hardness of water varies according to
the area in which you live.
The harder the water the more limestone
and mineral salt it contains.
Ask your Water Board to tell you the
degree of water hardness in your area.
The water softener in this machine is
pre-set for water having a maximum
hardness of 30°F (17 °dH). This setting is
satisfactory in most areas. If however you
live in an area where the water is
particularly hard — exceeding 30°F
(17 °dH) you can have the softener
adjusted to suit a hardness up to 50°F
(28 “dH).
If it is necessary to adjust the machine,
call the Zanussi Service Network or a
qualified plumber.
12
Rinse Aid
This special liquid is essential for good
results. It ensures quick drying and shiny
crockery and glass by helping the water to
run smoothly off the items before the
salts contained in the water can leave
streaks and marks.
The rinse aid dispenser, which
automatically dispenses the right amount
of liquid at the right time, is located inside
the door of the machine next to the
detergent dispenser (see fig. 5).

To fill the dispenser press the catch A
(fig. 6) to open the lid. Pour rinse aid into
the funnel. The container holds
approximately 150cc of rinse aid, which
will last for about 70 wash cycles.
To the left of the dispenser there is an
indicator which shows the level of liquid
in the dispenser B (fig. 6).
Adjusting the Quantity of Rinse Aid.
It may be necessary to adjust the quantity
of rinse aid dispensed if you live in either
a very hard or a very soft water district.
More is needed for hard and less for soft
water. Leave the dispenser in its preset
position when you first use the machine
and only adjust it if, after a few cycles you
notice any of the following:
A
Crockery remaining dull looking and/or
showing occasional round spots. If this is
so increase the quantity of rinse aid by
turning knob C (fig. 7) to the right.
B
Crockery feeling sticky or showing whitish
spots. If this is so decrease the quantity
of rinse aid, by turning knob C (fig. 7) to
the left.

Loading the Machine
Most tableware, cutlery and cookware can
be safely washed in the dishwasher.
Check the list on page 23 and do not put
these items in the machine. Remove
bigger scraps of food from the plates and
dishes; eg small bones, fish bones, scraps
of meat and vegetables — in fact anything
that can be scraped off easily. This will
prevent the filter from clogging. There is
no need to rinse the crockery before
putting it in the machine.
Open the door by pulling the handle
outwards.
Slide each basket out to load it.
The lower basket is designed to take
dinner plates (up to 27 cm — 10.6 ins —
diameter), serving dishes, cooking bowls,
pots, pans and cutlery. Cutlery should be
put in the removable cutlery basket.
Mix spoons with knives and forks so that
they will not stick together and prevent
the jets of water cleaning them properly.
Unless your cutlery has very thin handles,
put it in the basket with the handles
downwards. If the handles are so thin that
they stick through the bottom of the
basket, load them with the handles
upwards. The two diagrams (fig. 8 and
9 ) show how items can be arranged in
the bottom basket.

crockery in such a way that it obstructs
the water inlet funnel at the centre of the
basket.
After loading make sure that the spray
arm can turn freely.
Be absolutely sure not to load the

Raising and Lowering the Top Basket
If you have plates over 27 cm (10.6 ins)
diameter and up to 31 em (12.2 ins) the top
basket must be raised to a higher position
to accomodate them. The large plates can
then be stacked in the lower basket. To do
this take the front runner stops off the
top basket (see fig. 12) and remove the
basket. Then take off the rear runner
stops, pull out the slides and refit them in
a higher position (see fig. 13).
Replace the rear runners stops, then the
basket and finally the front runner stops.
Note
When the top basket is in the higher
position, it will only take plates up to
19 em (7.5 ins) diameter and you will not
be able to use the raised cup section.

Choosing the Right Detergent
Use only top quality detergent specially
made for dishwasher.
Filling with Detergent
Add the detergent after loading the
machine. To do this open the detergent
compartment on the inside of the door by
pushing back the lid catch E (fig. 14).
Pour the detergent into the
compartement. Close the lid firmly. The
detergent will be automatically dispensed
at the right time.
Quantity of Detergent
This depends on the brand you use, on the
degree of soil and the type of load.
Follow the directions on the powder
packet.
As a guide use:
4 tsps (25g) for normal loads
5 tsps (30g) for heavily soiled load.
If you don’t use enough powder the
results will be poor, on the other hand too
much powder will not improve results and
will just be wasted. You will soon find out
the right amount to add after using the
machine for a few days.
17

Programme Selection
The charts on pages 19-20 give details of
the programmes which your machine is
designed to carry out. You will soon
discover which programmes suit your type
of washing up.
If you half load the machine and want to
make up a full load later in the day after
another meal, use the rinse and hold
programme.
Starting the Machine
Turn on the water tap or taps which
supply the machine. Make sure that the
machine is plugged into the electric
socket and that the switch (if any) is on.
Close the door of the machine firmly after
loading it and adding the detergent.
On model DI 720
Turn the programme selector knob
clockwise until the index points exactly to
the required programme letter.
If required, press the water temperature
selection button and the Quick wash
button.
On models DI 104 B - DI 104 W
Depress the required wash programme
button (E).
Depress the economy drying button (D),
if so required.
