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
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.

Celling spray arm upper spray arm lower spray arm
Active Drying
Active Drying means the ventilation of a container without any movable parts
A plastic container is clipped into the opening in the container cover, from where
a hose is passed to the appliance base.
Function
A 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
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).

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 water

In the middle sequence, during time T2 the drain pump is stopped.
At the end of the drain step, the water level is checked.
If the switch back is reached, the drain step is terminated.
If the switch back isnt reached, the drain step is repeated.
A failure code is displayed, if after 2 drain steps, the switch back couldnt be reached.
In this case, the program is stopped.

6.1. Inputs and outputs: keys, LEDs and lamps
Arrangement and designation
The control class EDW2000 replaces the previous control classes Easytronic and Easytronic plus. For this reason there will be variants of appliances with combinations
of display and PAA (program run display) in the output area (right side of the appliance). 3 possible variants have been represented in the outlines below.
In this connection, the subdivision into "program selection, option selection, SZV, RLA, RAA and HWA" represent the currently defined standard division.
In coordination with the Development Department it is possible to alter the assignment depending on variant in order to react to possibly coming design variants!
It is possible that one or more of the keys are not assembled due to the device definition.
In this case, counting is (starting from the left)from the first existing key.
The keys which are not assembled are not counted.
This device documentation always assumes that the full number of keys are assembled!
Reduced key assemblies are specially important with customer and service functions,
as well as with the "Reset" function.
