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.

3.6 NTC-Temperature sensor wit
integrated turbidity sensor
NTC
Turbidity sensor
The turbidity sensor function is only activated in cycles AUTO
Function:
The input voltage with the turbidity sensor may be between 6 V
and 11.4 V. (The measurements are described in detail in the
chapter Measuring Points at the Electronic Control (in the base)).
For a clear water the output voltage must always be 4.3 V. If that
value differs due to soiling of the turbidity sensor after a longer
operational period, the Easytronic plus recontrols the input voltage
with the turbidity sensor automatically until the output voltage is
4.3 V. This happens during the final rinse cycle.
If the 4.3 V is not achieved within 8 seconds, the fault C5 is
stored in the fault memory. If the output voltage falls below 3 V in
the prewash cycle and below 3.8 V in the intermediate rinsing
cycle, turbid water will be detected. With the service test routine
the turbidity sensor will be calibrated to 3.5 V not with water but
with air.
That corresponds to 4.3 V with water.

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.

1. softener unit

chamber
3.11 Regenerating dosing
wit condenser
The water softening can be adjusted in 10 levels. The incoming
water flows until positon 5 to 85 % 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 8, 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.

5.1 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. The inlet valve (1) is located in the
base of the dishwasher. The safety outer hose (12) is connected to the re eneration chamber. If the
inner hose should burst, the water passes into the tub. The safety pressure switch activates the drain
pump and decreases the waterlevel down to normal level. An additional overflow protection is a
defined overflow throu h the re eneration chamber. The water flows into the bottom tray and
activates the float switch, which ener ises the drain pump. This drains the dishwasher preventin
water dama e.
Safety level
If the safety level is reached by over-filllin , the safety pressure switch starts the drain pump. The water
is only drained until it has reached the normal level because the reset point of the safety pressure
switch is above the switchpoint of the normal pressure 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 leaka e. 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).

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.
