1. GENERAL PRODUCT INFORMATION

1.1 Intelligent washing technology

In the dishwasher series 630 all top and middle class dishwasher models are equipped with an
electronic control. Advantage for use: the appliances provide a number of functions during which

the
dishwasher "decides" itself. Thus the appliances are enabled to optimally fulfill their main task, i. e. to
wash and dry dishes that are more or less heavily dirtied while consuming the lowest possible amount of
water, current and chemicals. This performance is supported by the following features:

• Aqua Sensor

• Regeneration electronic

• Optimally differentiated wash programs

• Warm water detection

The Aqua Sensor

The essential component of the "Intelligent washing technology" is the Aqua Sensor: an optical
measuring system to measure the turbidity of the wash water. The Aqua Sensor consists of an
infrared light barrier located in the wash water circuit between recirculation pump and spray arms.
This light barrier serves to detect the contamination of the water by substances that have come off
like grease, oil, protein.

The Aqua Sensor is activated in all programs that contain a prewash cycle. If the wash water is still
"clean" at the end of the prewash cycle, i. e. the turbidity does not exceed a determined limit value,
the wash water will be used for the subsequent wash cycle. If the water is more heavily
contaminated, it will be drained and replaced by fresh water from the water supply. In this way the
water consumption in case of standard dirtying of the dis hes is reduced by 4.5 ltrs. S aving is always
realised, if the water has not been heavily dirtied during the prewash cyle, i. e. "has not yet fulfilled
its task". This applies to moderately dirtied dishes and to dishes to which the dirt sticks such heavily
that it could not be removed during prewash. Also in this case clean water is not unnecessarily
drained. A comparable system for optical checking of the water contamination has so far not been
used by any competitor in Europe. In general, the Aqua Sensor is included in the standard
equipment of appliances with 5 programs and more (see appliance range and features).

Regeneration electronic

By means of the regeneration electronic the new dishwashers may regulate the consumption of
water and salt as required.

In contrast to mechanical dishwashers where a regeneration process is generally performed in any
wash program (regeneration of the softening system by means of a salt solution), the electronic
controls this regeneration process in accordance with the actual requirement. By means of the
water hardness preset at the dishwasher (see p. 13 - Softening system) the electronic counts the
number of wash baths that can be performed until the softening sy stem is "ex hausted". The number
of the actually performed wash baths is considered accordingly. When the highest-possible number
is reached, the regeneration process will be started.

Depending on the water hardness and the selected wash program regeneration may be performed
after every (31-50 dH) or only after the 30th wash program (0-3 dH). The regeneration electronic is
factory-set to level 5, i. e. 17-21 dH. W ith this presetting, regeneration is performed after 12 wash
baths, i. e. 3 standard programs (see p. 13 - Softening system). The advantage of this feature is that
only the amount of water and salt actually required for the respective water hardness will be used
for regeneration. The average salt consumption for each wash program is reduced by approx. 30%
from 25 g to 18 g.

The regeneration electronic is included in the standard equipment of dishwasher models with
electronic control.

Warm water detection

The electronic control reacts to the connection conditions of the appliance and thus enables the
unlimited use of all dishwasher models, with or without heat exchanger, in case of warm water
connection.

If the control recognises that the appliance has been connected to warm water supply (if the

measured temperature of the inlet water during the rinse cycle exceeds 45 °C), the heat exchanger
will not be filled for the drying cycle. In order to ensure the temperature difference required for
condensation, the temperature will be increased to 70 °C during the rinse cycle and thus the
inherent heat of the dishes increased.

1.2 Operation and handling

The design of the new dishwasher series 630 is especially characterised by easy operation and
activation of the most frequently used operating elements. Daily handling of the new dishwasher s is
convenient and user-friendly thanks to easily comprehensible operating sequences requiring only
little force. The most important elements are:

• Selection of all functions via short-stroke buttons

• Remaining cycle time display

• Detergent metering chamber

• Filter system

• Door brake

Depending on the equipment, delayed program start can be selected on some dishwasher models.
This start time preselection is possible up to 24 hour s in Top electronic models and up to 9 hours in
Comfort electronic models.

Also after the program sequence has been started changing to another program or operating mode
is still possible by pressing the respective button twice. This safety feature prev ents unintentional
changing during a running program. In case of an intentional program change, the running program
is interrupted and the sequence continued at the respective point in the newly selected program. As
soon as "0" is displayed in the figure panel, the dishwasher has returned to the initial position and
can be newly started.

Remaining cyle time display

In case of dishwashers equipped with Top electronic the user is informed on the stage of the
running wash program: the remaining cycle time until program end (in minutes) is displayed on the
operating panel.

The remaining cycle time display is newly calculated and thus updated several times during the
program sequence. It mainly depends on the following factors: quantity and type of the dishes,
temperature of the inlet water as well as degree of dirtying of the dishes. For the initial calculation
after switching on of the dishwasher, always the values of the preceeding pogram are used. The
less the above-mentioned factors deviate, the less corrections are made as compared to the time
displayed first. The required correction amounts to approx. 10 minutes in the least favour able case.
The display is quartz-controlled and thus also reliable in case of deviations of the mains frequency.

In case of dishwashers equipped with Comfort electronic the program sequence display is
performed by means of an LED "bar", which indicates the individual phases of the wash program
(basically comparable to the program "indicator" of the previous series).

Filter system

The filter system consists of 3 parts: coarse, fine and micro-filter. The coarse and micro filter may be
taken out by means of of a joint handle, the fine filter is separately located in the container bottom.

Due to the surface increased by 30 % and the permanent cleaning during the wash cycle by means
of a special nozzle at the underside of the bottom spray arm, the fine filter has to be checked for
clogging only twice per year.

Furthermore, the newly designed coarse filter serves for improved self-cleaning. It is open towards
the drain pump and allows all foreign matters to pass thr ough that may be bor ne by the dr ain pump.
In this way it is ensured that the filter s ystem will not be clogged by left-overs of food. All larger
matters of dirt that cannot be transported by the drain pump are collected in the collection groove of
the coarse filter from where they can be easily removed.

Filter system

Door brake

In contrast to the dishwasher models of the previous series the door does not automatically fall
down but remains in any desired position. This feature allows to open the door only half the
way, e. g., when charging the upper basket or during filling of the detergent chamber and thus
enables the user to close the door without bending down.

1.3 Improved installation and connection

Erection, installation and connection have been considerably facilitated for the dishwasher models
of the new series thus enabling the kitchen fitter and plumber to intergrate our dishwashers more
quickly and more easily into the kitchen. The following items are to be especially noted:

• Aqua Stop

• Installation reserve in the appliance height

• Adjustments from the front

• Infinite panel adaptation

Aqua Stop

Above all, the installation and handling of the Aqua Stop system has been facilitated by a number of
improvements. Inlet and outlet hose are separated from each other in any dishwasher model in
order to be more flexible in case of unfavourably located water connections. The Aqua Stop housing
is smaller althouhg its operativeness remains unchanged. In this way, installation thorugh the
bottom cupboards of the kitchen is facilitated .

A significant a dvantage of t he new Aqua S top is that it can be installe d in any desired pos ition,
also at an angle, hori zonally or, in extr eme cases, overhe ad. Besides that, the minimum height
for the inlet connection (0.3 m above the installation surface of the appliance) needs no longer
to be observed.

To this end, the valve system has been changed: the pneumatic valve in the Aqua Stop housing
has been replace d by a second magne tic valve. As the valves are dir ectly located on the water
tap and are c losed in d e-energiz ed condit ion, safety can be continually ensured i ndependent of
the mains. The Aqua Stop guarantee is of course also fully granted for the new dishwasher
models.

Furthermore, the discharge hose can be installed at any location on the dishwashers of the new
series, as the verti cal instal lati on tha t has been req uir ed so far is no longe r nece ssar y due to the
"hose bend". This has been rea lised by a vertic al installation and ventilation of the water outlet
already in the dishwasher itself. With respect to the appliance, it is thus ensured that no
malfunctions like emptying of the appliance or penetration of dirty water from clogged drain
pipes may occur.

In order to extend the inlet hose, acc. part no. 485 may be installed at the new dishwasher
models. The di scha rge h ose ca n be ex tended by means of a commerc ial plastic hose to
max. 4 m, if required .

Installation reserve in the appliance height

To faciliate the installation the body height of all appliances of the new series, including stand-alone
and built-under models suitable for decoration, is reduced by 10 mm (see p. 18 - Installation
dimensions). This ensures, especially in case of replacement, easy installation also with narrow
niche conditions, e. g. unlevel ground, carpet, subsequently layed flooring materials. Furthermore,
the appliances can thus also be installed in kitchens with special niche dimensions (heights between
810 and 820 mm).

Adjustments from the front

The height of the rear foot as well as the prestr ess of the door springs (weight compensation of
furniture fronts) can be adjusted from the front at all intergrated and fully integrated dishwasher
models of the new series.

Adjustment of door springs and rear foot

Thus the appliance needs not to be repeatedly inserted and pulled out for alignment and
adjustment. All adjustments may be performed by means of the s crews loc ated in the base after the
appliance has been inserted into the niche.

At the same time, the design of the door springs has been changed in s uch a way that they are
suitable for furniture fronts of max. 10.5 kg in case of built-in appliances.

Infinite panel adaptation

In order to adapt the panel height to the drawer dimensions of the kitchen furniture a set of cover
strips with infinitely adjustable height is used for integrated appliances. This set consists of 4 strips
with a height of 8 mm each, which may be each telescoped into each other up to 3 mm. By means
of the complete set, a height difference of up to 32 mm may thus be compensated. The strips may
be assembled and disassembled without tool.

An exception are all appliances equipped with stainless steel operation panel. For these models 3
stainless strips are supplied, which may be used alternatively.

Spare part no. 42 67 44 up to 17.5 mm

42 66 11 up to 27.5 mm
42 66 10 up to 37.5 mm

Two further stainless steel strips may be supplied as accessory:
Spare part no. 42 67 45 up to 47.5 mm

Appliance heights of 82 and 87 cm

In the kitchens, increased worktop heights tend to gain more and more acceptance for ergonomical
reasons. Today 55% of the new kitchens in Germany are already equipped with worktop heights of
91 cm and more. In Scandinavia, Great Britain and the Netherlands the proporotions of these height
dimensions are significantly higher.

Especially for those "high" kitchens, a further innovation is provided: dishwashers with a height
increased by 5 cm which ensure optimal utilisation of the available space. In contrast to
dishwashers with "normal" height these "extra-large" dishwashers offer an increased internal height
of 5 cm. These dishwashers are suitable for all kitchens with a niche height of at least 86 cm and a
body size (niche height minus base height) between 70 and 72 cm. In comparison with that: The
"normal" appliances are suitable for body sizes of 65 to 72 cm, with the minimum niche dimension
amounting to 81 cm.

In order to select the ideal appliance for a certain kitchen it is thus important to know the base
height in addition to the existing niche height, as the application of the dishwasher is determined by
the difference between them.

1.4 Further technical innovations

In the following chapters further innovations of the dishwasher series 630 are summarized and
explained. These modifications have also resulted in improved operation, performance, quality and
optical aspects of the appliance.

1.4.1 Wash system

The wash system of the dishwashers has been further developed with the aim to achieve an optimal
cleaning result with the lowest possible consumption of water and energy. The following appliance
components contribute to reach this aim:

Heat exchanger

The heat exchanger, which is still an exc lusive feature of Küppersbusch appliances, is also offered
in the new series. The heat exchanger offers a multitude of operating advantages like economical,
hygienic drying, gentle temperature guidance, no penetration of steam when the door is opened
after the program end. The heat exchanger is, above all, installed in top class dishwashers, partially
also in middle class appliances . Due to the warm water detection of the electronic sys tem a good
drying performance is also achieved in case of warm water connection.

Spray arms

An obvious characteristic feature of the new series is represented by the curved "wave-type spray
arms" that are exclusively installed in Küppersbusch dishwashers. The advantage of this design is
an improved spraying of the entire dishwasher interior, i. e. no more "dead angles" that are not
reached by the spray arms. All pieces of the dishes are thus reached by the spraying jets and
cleaned accordingly.

Both spray arms of the new dishwasher series - also the lower arm - are made of plastic. This
enables a more precise design and more exact alignment of the spraying nozzles as well as a lower
weight which results in a faster rotation of the spray arms and thus an improved distribution of the
water.

Water guidance

The entire water guidance from the pump casing to the spray arms and the top spray has been
newly designed and is now located in the inside of the rinse container. This leads to a reduction of
the inactive water quantity and thus to an improved washing result.

The water guidance to the upper spray arm is also new. The spray arm is connected to the supply
by means of a movable coupling and directly mounted at the upper basket. For this reason, no more
space-consuming funnel is required for any appliance. Thanks to this new coupling, height
adjustment and even removal of the upper basket with spray arm is now also possible without
funnel. In the latter case, the entire internal space of the appliance (51 or 56 cm, respectively) is
then available, for example for washing baking trays.

11 For internal use only

Flow heater

All appliances of whatever class belonging to the dishwasher series 630 are equipped with an
integrated flow heater to heat the water. Thus the new generation does not include appliances with
visible tubular heating any more. The complete range of advantages provided by the flow heater
(increased internal height, no damaging of plastic dishes, no carbonisation of remaining food) is only

provided in Küppersbusch appliances.

1.4.2 Dish baskets

In the new series two different types of dish baskets are used: standard baskets and universal
baskets.

The standard baskets are identical with those of the series 624 (dishwashers with heat exchanger).
The upper basket is suitable for up to 4 rows of glasses or cups and one row of small plates. The
lower basket is equipped with two rows of plates designed as fixed or removable inserts, depending
on the model (see "Appliance range and equipment"). In case of the appliances with removable
inserts the special accessory "Special glass basket" may be used.

The universal baskets are already known from the series 624 ( upper basket dishwashers). They
offer variable charging of the upper and lower basket and allow location of 6 standard dishes
including all parts like pots, bowls and pans only in the upper basket. The universal baskets are
included in the standard equipment of all upper basket dishwashers.

Furthermore, the new dishwasher models allow adjustment of the basket height for the upper
basket appliances which means a further improv ement of the flexible charging. The heights are fac­tory-set to 26 cm at the top and 25 cm at the bottom. If required, this setting can be changed to 21
cm at the top and 30 cm at the bottom. Thus, these appliances are also suitable for pieces of dishes
up to a height of 30 cm (if arranged at an angle even up to 33 cm). Adjustment of the upper basket
has been facilitated: the basket is simply lifted of the guide rails and inserted in the second height
position.

The standard baskets are generally supplied with 21 cm top height and 30 cm bottom height. No
adjustment is possible here. The heights of the "high" appliance types amount to 26 cm at the top
and 30 cm at the bottom, no adjustment possible.

1.4.3 Softening system

The filling capacity of the salt container of the new dishwasher models amounts to 1.5 kg and is
sufficient for approx. 70 standard wash cycles with a water hardness of 5. After lighting up of the
salt refill indicator approx. 5 wash cycles can still be peformed before the salt container is
completely empty. The operation of the softening system depends on the respective control.

1.4.4 Noise

The appliances of the new series are equipped with 2 noise insulating stages: 48 dB and 45 dB.
These values always apply to the sound power dB (re 1 pW) for a built-under appliance.

Apart from some exceptions, all electronic appliances will be equipped with 48 dB. This v alue is so
low that it is not audible compared to the normal noise level in the r oom. This equipment enables us
to offer a large variety of low-noise dishwashers.

1.4.5 Turbo drying

The electronic appliances of the new dishwasher series enable the operator, if desired, to select a
more intensive drying function which, of course, results in an increased energy consumption.

In order to program this turbo drying, switch the dishwasher on while keeping the button

"Heavy-load 65°" depressed. The preset value "0" (= turbo drying off) will then be indicated in the
7-segment display. The function is actually activated by pressing the button "Heavy-load 65°" once
again. The value "1" (= turbo drying on) will be displayed. After switching off the appliance, the new
value is stored.

1.4.6 Connection value

All dishwashers of the new series have a heating capacity of 2150 W and thus a connection value of
2300 W; therefore a fuse protection of at least 10 A is required. Due to this feature, all dishwashers
may also be used at locations where no 16 A protection is available in the future. Special
low-protection variants, as are partially existing today, are no longer required.

1.4.7 Rinse aid metering chamber

The location, filling, metering adjustment and refill indicator of the rinse aid chamber have been
taken over from the acutal dishwasher models. Only the lid has been modified; it is now fixed to the
cabinet. Thus loss or misplacement of the lid is avoided.

The filling capacity of the rinse aid chamber amounts to 110 ml; in position 3, 3 ml are added per
wash program. Thus approx. 25 rinse cycles may be performed until the refill indicator lights up.

1.4.8 Ventilation

The inner container of the new dishwashers has no openings in the top, lateral and rear wall. The
only outlet for the produced steam is located in the inner door, integrated in the refill assembly for
detergent and rinse aid. The steam condenses in a separate channel in the inner door and is
recirculated below the door to the container bottom. In this way, the penetration of the steam
towards the top which results in the risk of a damaging of the worktops in this area is avoided.

1.4.9 Operating safety

All appliances (except fully integrated appliances) are equipped with a safety device in case of
opening during the program sequence, i. e. a direct circuit-breaker which is operated when the door
opener is activated. When the appliance is opened, it will be immediately switched off via the mains
switch. After closing the door and switching on again, the program will be continued at the same
point. Besides that, all upper basket dishwashers are equipped with a child-proof loc k located in the
door handle to protect the appliance from being switched on unintentionally. When the child-proof
lock has been activated, the appliance can only be opened by pressing an additional pin in the
handle recess. If not required, the child-proof lock can be deactivated by means of a ballpen or
equivalent.

1.4.10 Salt refilling

The refilling of regeneration salt in the container bottom has been facilitated by shifting the filling
opening towards the front. Furthermore, a salt funnel is supplied with all appliances.

1.4.11 Feet and skids

The feet are made of plastic with extended foot plates in order to avoid damaging of flooring
materials. Stand-alone appliances and appliance suitable for decoration are equipped with four,
built-in appliances with three feet (two at the front, one at the rear in the middle) that ensure stable
standing on any ground.

The skids for easier sliding of the appliance into the furniture niche are integrated in the bottom tub.
In this way the installation of the appliances is even more faciliated.

1.4.12 Mounting at the kitchen furniture

For mounting the built-under appliances (suitable for decoration, integrated and fully integrated) at
the kitchen furniture two metal brackets to be inserted into the force sensors at the top of the
appliance are supplied. Each of the metal brackets has two fastening locations. In case mounting at
the worktop is not possible (e. g. stone or granite worktops), these brackets may als o be used for
lateral mounting at the furniture body.

In order to protect kitchen worktops against being damaged by emerging steam, for example when
opening the door during the program sequence, all built-under appliances are supplied with a s team
protection foil to be mounted at the underside of the worktop.

2.8 Spray system

The rotary spray system cons ists of three spray levels , the lower and upper spray arm and a top
spray .

The water supply to the upper spray arm and the top spray is brought through the inlet pipe
atta ched to t he inside of the co ntainer r ear wall . This pip e is conne cted by a direct connection
with the flow heater under the pump casing at one of its two outlets.

The upp e r sp r a y a rm i s di r e ct l y f as t e n ed w ith its in l et p ip e to t he u pp e r ba s k e t . The connection to
the inlet pipe is thro ugh a var i ab le cou pl in g. In mo dels w it h h ei gh t adj ust ab le uppe r basket, the water entry
is adapted to the spray arm using this variable coupling.

The connection to the inlet pipe is through a variable coupling. In models with height adjustable upper
basket, the water en tr y is adap te d to t he sp r ay ar m u sin g this var i ab le co up li ng .

The lower spray arm with its bearing is connected directly through the pump casing at the
second outlet of the flo w heat er.

The valve for the upper basket wash cycle is located in this outlet.

2.9 Wash and pump system

The switching mechanism with the permanent magnet and actuator is attached beneath the flow
heater. The recirculation and drain pump as well as the flow heater are attached to the pump casing
using plug connections. The flow heater is additionally screwed to the pump casing for pressure
resistance.

The pump casing is covered by the area fine filter. With the combined coarse and micro-filter, the
fine filter is attached to the floor of the pump casing using a bayonette mount. The washing liquid
accumulating in the pump casing is drawn by the recirculation pump and pressed into the flow
heater. At the appropriate pressure a flange membrane actuates the pressure switch for the heater
A series connected temperature controller with a turn-off temperature of 85 °C prevents

overheating.
This temperature switch is combined with an NTC resistor (Negative Temperature Coefficient)

(otherwise 55/88 °C) into a single component, and is only used in models with electronic control.
The NTC surface has direct contact with the wash liquid. At the outlet of the flow heater is the Aqua

sensor with its sensor in the flow current of the wash liquid for detecting turbidity of the water. With
the drain pump directly attached to the pump casing, the impeller and the check valve are
accessible after removing the cover in the rinse container.

3. FUNCTION DESCRIPTION

3.1 Water inlet for models with heat exchanger and electronic control

3.2 Aqua Stop system

The system consists of two series connected electrical solenoids, the fill solenoid and the safety
so le no id . The s olenoid combin ation is enclo sed in a housin g and attached at the water inlet ju nction.
From the sole n oid, the supply line is led to the integrated water inlet by the heat exchanger , and the
electrical control line for the solenoids is led into the tub through a leak water tube attached to the
solenoid housing.

3.3 Safety function

All leaks inside the appliance are collected in the tub, including leaks in the fill and safety solenoid
and the water supply line, which are led to the tub through the leak water tube. At a preset level in
the tub, the float actuates a switch lever for the safety switch on the level sensor, which electr ically
shuts off the fill and safety solenoid. Simultaneously the drain pump is turned on, the wash liquid is
removed from the rinse container, and the pump runs continuously.

Note: In models with electronic controls, the electronic system is turned off by a safety switch.

3.4 Water inlet with heat exchanger prefill (V F1)
(models with electronic control only)

After the fill solenoid is opened, the water flows to the integrated inlet over the fr ee flow line into the
softener and then as softened water into the heat exchanger. After the regeneration chamber is
filled the water flows through the overflow channel into the thredtle cup of the level sensor. The
pressure buildup in the pressure socket c auses the level switch to open the heat ex changer drain
valve.

The electronic determines the time between the open command of the fill solenoid and the closing
of the level switch (f1). From this time the additional fill time of the fill solenoid is calculated. At each
first filling of a wash cycle, 200 ml more water than the normal amount is filled. With this water
amount, for the first fill of the wash cycle the water loss is c ompensated which is caused by the
wetting of the dry dishes. Redation of the recirculation pump is ensured and in the following fill
operations water is saved. The recirculation pump is turned on time-delayed, the drain valve stays
open until the heat exchanger is fully emptied.

3.6 Water inlet without heat exchanger

After the fill sole noid op en s, w ater flo ws t o the in te gra te d i nl et acro ss th e fr ee fl ow li ne in to th e re ge ne rat io n
chamber. After the regeneration chamber is filled, the water flows over the overflow channel through
the softener, then as soft water into the level sensor and pump casing. After the static level is reached,
the output signal from the level pressure sensor is picked up the by the electroni c s and t h e r e c irculation
pump is turned on. When the rerecirculation pump starts, the level pressure switch is reset.
Dynamic filling continues until the level switch is activated again, which means the wash level has been
reached.

3.7 Regenerating with heat exchanger

The water quantities of the wash cycles which have already run are registered by the electronic and
determine the timing for regenerating of the softener. Before each regeneration step the electronic
system checks whether the capacity of the softener is still sufficient for a complete normal program
sequence. If not, another regeneration is done. During regeneration the regenerating valve on the
softener is opened. The reservoired quantity of water flows across the valve into the salt container ,
is enriched with salt, and flows as brine through the softener into the pump casing. To increase the
effect, another 360 ml are cycled. To this end the fill s olenoid is actuated for a short time with open
drain valve. To clear the dissolved hard ening agents, the softe ner is r insed through in two pha ses during
the drying cycle.

3.8 Regenerating without heat exchanger

The water quantities of the wash cycles which have already run are registered by the electronics
and determine the timing for regenerating of the softener. Before each regeneration step the
electronics checks whether the capacity of the softener is still suffic ient for a complete normal cycle.
If not, another regeneration is done. In regenerating the regenerating valve on the softener is opened.
The reservoired quantity of water flows across the valve into the salt reservoir container, is enriched
with salt, and flows as brine through the softener into the pump casing. To increase the effect,
another 360 ml are added. To this end the fill solenoid is actuated for a short time with open drain
val ve. To c lear the dissolv ed hardening agents, the softener is rinsed through in two phases at the
beginning of the ne xt cycle.

3.9 Level sensor system for fill level

After the heat exchanger and re generation chambe r are filled, the water flows over the drain chann el
into the level sensor housing to the level pressure chamber. The throttle cup under the pressure
chamber ensures that the level pressure chamber is filled first, until the corresponding pressure for
actuating the level switch is reached. The overflow water flows directly into the pump casing.

3.10 Safety level

If the fill solenoid does not shut off, filling continues until the level in the safety level chamber is
reac hed and the flo at act uate s t he s afet y switch. The safety level chamber is wired ahead of the
level chamber and is located between the level chamber and the drain to the pump casing.

The safety switch is used to turn the fill and safety solenoid off and the drain pump on.

3.11 Aqua Sensor

The infrared LED and the phototransistor are located in a U-shaped, light-passing housing opposite
each other on a circuit board. The infrared diode sends its infrared light through the water which passes
between it and the phototransistor, whereby light which reaches the phototransistor switches it on.

If the water is excessively cloudy, the light intensity is not sufficient to switch the phototransistor.
The absence of a voltage signal is detected by the microcomputer, and the required water change is
carried out for cycles which include a prewash.

If the water remains clear enough, it is kept in the rinse container for use in the wash cycle.

3.12 Dispenser detergent/rinse aid

The release mechanism is controlled by a thermoactuator.
The first actuation causes the cover of the detergent dispenser to open, and at the same time the

release tab ratchets into the switch detent of the rinse aid lever, so that the next operation of the
actuator causes the metering plunger of the rinse aid to lift.

When repairs or inspections of the applianc e are done, the release mechanism must be reset to the
initial position by closing and opening the cover.

7.4 Customer Service check program - electronic dishwashers

The new dishwasher series corresponds to the state-of-the-art. It is not only characterised by the
completely new design structure but also by the great number of technical details with respect to
function and control. Special importance has been attached above all to even higher quality
standards.
The customer service is requested to participate in maintaining this quality standard in case of
failures by quick reaction and expertise. Any special matters are to be communicated to the
department VKS-H by written information and return of the relevant components.

IMPORTANT!
Reset the electronic after any customer service call.

- Switch on the mains switch.

- Press buttons S2 and S4 approx. 3 seconds (display: 0).

- Wait until the drain pump switches off (approx. 1 min.).

- Switch off the mains switch.

7.4.1 Button designations, e. g.

70 °C = S1, 55 °C = S4

Heavy-load 65 °C = S2, 40 °C = S5
Normal 55 °C = S3, 30 °C = S6

Note: Independent of the number of control buttons (acc. to model), the check program is always

started by simultaneously pressing button 65 °C and the next but one button.

7.4.2 Starting the check program

- Keep button S2 and S4 depressed.

- Switch on the mains switch.
Note: If the buttons are depressed, the model no. of the electronic will be indicated in the display

(e. g. 20, 21..., important as reference in case of queries).

7.6 Starting the Customer Service program

- Start by simultaneously pressing the buttons S2 and S4 once again.
CAUTION! A figure between 0 and 15 is indidated in the display (0 = no fault).

The electronic system checks 4 functions and indicates faults that have occurred with the respective
fault numbers in the display. The fault numbers are displayed as follows:

1 Aqua Sensor defective
2 Heating fault
4 Filling fault (time fault or hardware fault)
8 NTC fault

For multiple faults, the values are added on!

The fault display is only extinguished after a repair, if a complete function check has been
performed afterwards, e. g. in case of a heating fault after the temperature has been reached.

The figure 1 which is indicated in the display shortly after the start (approx. 5 sec) is no fault no. but
rather caused by the calibration process of the Aqua Sensor.

The individual check positions are automatically switched.
Note: Keeping the button S3 depressed enables steps to be skipped, e. g. the step out of the

heating position. The skipped functions are displayed as fault number.

7.7 Fault numbers

Fault no. 1: Aqua Sensor

Failure during the calibration process at the Aqua Sensor, or no Aqua Sensor available

- electrical defect

- sensor contaminated / calcified

- contact fault

Fault no. 2: Heating fault

The max. heating time of 60 min. has been exceeded.

- heating defective

- pressure switch has no function

- 85° C thermo has no passage (electr. defect, temperature is exceeded)

- heating without voltage

- contact fault
The wash time in case of a defective heating amounts to 75 to 300 min. depending on the program.

Fault no. 4: Filling fault

The max. filling time of 10 min. has been exceeded.

- no water supply

- poor water pressure

- Aqua Stop valve defective

53 For internal use only

CAUTION! This step cannot be skipped by means of button 3. In case of intermittent filling and

draining (electronic can be switched off during draining depending on the model)
check the level switch.

Fault no. 8: NTC fault

The NTC resistance is beyond the tolerance range.

- resistance with water temperature 25° +/- 8° ~ 48 KOhm

- resistance with water temperature 60° +/- 6° ~ 11 KOhm

- contact fault

- line interruption

- etc.
CAUTION! The NTC resistance value for the indication of the fault no. is checked in cold condition.

The NTC controlled heating steps stored in the program are skipped and the selected
temperature will not be reached.

7.8 Storage of fault numbers

The electronic AKO 546 304 (art. no. 1 738 300 130) stores the fault numbers only at the end of a
terminated wash program. If the appliance is switched off by the customer beforehand (mains
switch, door switch, power failure) no fault will be stored.

7.9 Remaining cycle time display

The remaining cycle time display is self-learning and calculates the expected washing time
remaining up to the program end. The remaining cycle time is calculated during the program
sequence after each heating phase. A new time calculation is also performed in case of a change of
the wash program and in case of a program interruption (mains switch, door switch, power failure).
If the washing time is longer than calculated due to failures or defects, "1" is persistently indicated in
the display. After the last draining cycle at the program end the display changes over to "0".

7.10 Operation - wash program

In order to change the wash program the newly selected program button has to be pressed twice
depending on the appliance type. This also applies for changing over between one-basket and two­basket operation and vice versa.
The changed selection is immediately confirmed by lighting up of the respective LED.
Re-programming within the electronic is only performed after changing of a program section, e. g.
after switchover from the prewash to the wash program.

Depending on the model the filling fault is indicated in the display by an "F" (e. g. if the water tap is
closed).

The fault display is extinguished when the fili switch F1 is activated.

The salt consumption values are summarised in the following table:

Water hardness (°dH) Water hardness (mmol/l) Setting Degree Salt used per cycle (g)

0 - 3 0 - 0,6 0 0
4 - 6 0,7 - 1,1 1 4

22 - 30 3,8 - 5,4 6 27
31 - 50 5,5 - 8,9 7 54

To set the water hardness range (0 - 7), turn the appliance on while pressing the "Normal 55°C"
button. A preset value of "5" will then appear in the display.

To change this preset value, press the "Normal 55 °C" button repeatedly. After the appliance is tur­ned off, this new value will be retained.

In mechanically controlled models, regeneration of the water softener is carried out during each
wash program. Water hardness is set in steps between 0 - 3, using the switch located in the salt
refill opening in the container bottom.

8.2 Indications in the display and of the LEDs for electronic controls with
one 7-segment display

WASH PROGRAM

In the normal program sequence, i. e. dishwasher
switched on by means of the mains switch without
pressing an additional button.

The upper basket LED lights up, if the upper
basket function has been selected.

The refill LEDs light up if refilling is required.
Caution! With hardness set to 0, the salt refill LED
will not light at all.

A program LED lights.

When pressing the time preselection button figures
0-9 may be displ ayed in th e 7- segm ent di splay. "0"
is extinguished after 4 seconds.

During the prog r am se qu en ce on e si ng le bar of the
7-segment display is lit.

The upper one is lit during
prewash and wash, the medium on e during inter­mediate wash and r inse, the lower one during dry­ing.

At the program end ""0" will be displayed.

If a filling fault occurs during the filling process (see
fault 4) "F" is d ispl ayed in t he 7-s egm ent di spla y. If
the filling level is reached during this process but
not detected, the ap pliance switche s from filling to
pumping and vice versa. If no filling is perfor med,
the applianc e is out of operation u ntil the level is
reached. As long as "F" is displayed, the filling
valve must be activated. (Buzzing).

CHECK PROGRAM

In the special program "Customer Service check

program", i. e. the buttons HEAVY-LOAD 65 °C and
ECO are presse d up on sw itch ing on t he mains swit ch .

As long as the buttons HEAVY-LOAD 65 °C and
ECO are kept depre ss ed , the en co di ng is ind ic at ed
in the 7-segment display. Display 0-7, depending
on the encoder plug. 0 means without encoding
plug. Up to now appliances encoded 0, 1 and 2
have been manufactured.

The LEDs of the programs HEAVY-LOAD 65 °C
and ECO blink to indicate the special program
"Customer Service check program".

If the buttons are released, the mode "button
mirrowing" is active, i. e. the LED of the assigned
button will light, if the respective button is pressed.
This does not apply for the button of the normal
program. If this button is pressed in "button
mirrowing", not only the program LED Normal will
light, but also the refill LEDs and all segments of
the 7-segment display, i. e. "8".

If the buttons HEAVY-LOAD 65 °C and ECO are
again simultaneously pressed, the program cycle of
the special program "Customer Service check
program" is started. The following characters are
indicated in the 7-segment display as listed:
0,1,2,3,4,5,6,7,8,9,A,b,c,d,E,F

The end of the "C ustomer Service ch eck progr am"
is not indicated.
Note: See "Customer Service check program".
The Customer Service check program is only
performed with the upper basket washing function,
i. e. in case of appliances with heat exchanger and
without shut-off valve for the lower spray arm
washing is performed with the water amount for
upper basket washing (3.6 l) during 2-basket
operation.

Fault 1, Turbidity sensor system defective

The turbidity sensor is checked after the first pump step, i.e. it is de­cided after the first pump step whether fault 1 is displayed or not.

Possible causes:

- no turbidity sensor available

- turbidity sensor not calibrated (turbidity sensor defective)

- connection or plug fault

- electronic component for turbidity sensor evaluation defective
electronic defective

Fault 2, Heating fault
If the final temperature is not reached after 60 min. fault no. 2
will be displayed.
Possible causes:

- heating defective

- pressure switch defective

- thermal switch 85° defective (always open)

- no water in appliance

- heating relay or electronic control defective

- connection or plug fault

- recirculation pump partially inoperative, motor circuit-breaker
triggers

Note:

In case of a defective heating the washing time amounts to 75 to
300 minutes depending on the program.

Fault 4, Filling fault
If the filling level is not reached after 6 minutes, fault no. 4 will
be displayed.
Possible causes:

- water tap closed

- filling valve defective

- connection or plug fault
