The detergent compartment 1 is filling corresponding to the set dosing
quantity when the door is open. Possibly existing rinse-aid in compartments
2 and 3 flows back into the storage tank of the rinse-aid. The detergent
trays are filled up. The door will be closed and the detergent for prewash
will be rinsed out through the slots in the detergent dispenser cover.
During the washing cycle the coil is switched on and the detergent
compartment cover releases the detergent. The rinse-aid flows from
compartment 1 into compartment 2.
After switching off the coil, the rinse-aid flows from compartment 2 into
compartment 3.
During the rinse cycle, the coil will be switched on when the rinse is warmed
and the rinse-aid runs from compartment 3 into the rinse tank. At the same
time, the remaining rinse-aid (15 %) runs from compartment 1 into
compartment 2.
With the coil switched off, the rinse-aid flows from compartment 2 into
compartment 3.
During the rinse cycle, the coil is always switched on twice. When it is
switched on the second time, the remaining rinse-aid flows into the rinse
tank.

3.9 Spray arms
The new cutlery basket is placed at the upper diswasher basket. The celling sprayarm sprays the water
directly onto the cutlery basket and tguarantees an excellent washing result with the cutlery placed in
that basket.
Function mode of the condensing drying
Rinse tank, fan and regenerating dosing with
condenser form a closed circuit. The humid air is
sucked from the top of the rinse tank and blown
through an air guide between rinse tank and
regenerating dosing. Thereby the air gets dry and
the condensate is guided to the drain tub.
The dry air gets through the rinse tank ventilation
into the rinse tank. During the drying phase, the
condenser is additionally cooled with 1 liter of
water.

Active Drying
ctive Drying means the ventilation of a container without any movable parts
plastic container is clipped into the opening in the container cover, from where
a hose is passed to the appliance base.
Function
small quantity of moist air and some condensate
emerge from the hose. The condensate is collected
in the base side sections where it will evaporate.
If a larger quantity of condensate should be present
(due to many subsequent programme cycles) the
hose end will be immerged, thus stopping both the
convection and the condensating process in the
hose.
Flooding of the sections is therefore excluded. Only
very little moist air will be present.

1. softener unit

chamber
3.11 Regenerating dosing
with condenser
The water softening can be adjusted in 10 levels. The incoming
water flows until positon 5 to 5 % through the softener which
works according to the ion exchange principle. The ion exchanger
is filled with small epoxy resin balls. The resins exchange the
hardness constituents (calcium and magnesium), for sodium
ions.
When all the sodium ions are used up, it is necessary to
regenerate the softener. This is done by flushing a brine solution
through the softener.
Afterwards the softener is washed out with fresh water and is now
fully effective.
Depending on the water hardness, regeneration is only necessary
after several wash cycles.
The remaining 15 % of water flow through the rinse tank ventilation
directly into the appliance.
From setting of level 6, the whole water flows through the
softener. For this purpose you also have to set mechanically from
0 to 1 with the regenerating dosing.
With the setting of level 9, it is additionally regenerated after the
washing in a rinse cycle. With the settings 1 to , it is regenerated
after the final rinse depending on need. The softening system is
designed for a water hardness of up to 70 °dH.
With every filling step, the condenser
cools down due to the cold incoming
water. Therefore another 1 liter of water
is required during the drying cycle.

All-Around Water Protection
Aqua-Control Inlet Hose
The inlet hose has a double-wall construction. The inner hose is equipped with a flow restrictor built into the
tap connection, and has a flow rate of 4 litres per minute. If the inner tube starts bursting, the water reaches
the floor pan, gets diverted to the float switch in the floor pan and enables the drainage protection.
In this case the electric valve at the water hose get voltage free and the water connection gets locked.
The drain pump additionally pumps off the dishwasher so that no damage by water could be
produced.
An additional overflow protection is a defined overflow through the regeneration chamber. The water flows
into the bottom tray and activates the float switch, which energises the drain pump. This drains the
dishwasher preventing water damage.
Safety level
If the water level in the detergent dispenser transcends the overflow protection switch Safety level (4), the
water passes over the overflow protection switch (5) in the floor pan and also activates the float switch.
Leakage Protection
The anti-flood switch in the base tray will activate the drain pump and drain the water from the tub in the
event of an internal leakage. If the float switch is activated, all electric components are switched off except
the electronic and the drain pump.

5.2 Water Inlet
The water flows into the regeneration dosage chamber (7) via inlet valve (1), over air break (2), into
regeneration dosage chambers (3) into softener (8). At this oint the water divides. 1/4 of the water
enters the tub through the vent (23). 3/4 of the water enters the sum (24) through hose (6).
The level control chamber built into the sum o erates the ressure switch (15).

5.3 Draining
During the wash cycle the water is pumped out at various stages. First the draining water cleans the
filters (16). The filters are open at the bottom which allows any soilage to be rinsed off sufficiently.
There is a non-return valve ( 0) at the inlet connection to the drain pump (19). This valve prevents the
