Electronic
On electronic models, a micro processor controls all
components, this is done using triacs. The electronic also
memorizes all programme data.
Drying Fan
The drying fan sucks the humid air from the
tub, and mixes it with dry air which is drawn up
from in between the door panels (1) and blows
it out through a vent situated below the door
handle (2).
During the wash cycle the fan intake vent on
the inside of the door is closed by a
thermoelectric valve (3).
Servo Door Lock
Fully integrated dishwashers have a servo door lock. Once the
program has started the door is locked automatically, however
the door can be openend by using extra effort.

Water Softening
The components required for water softening.
1. softener unit
2. regeneration dosage chamber
The incoming water flows 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 softening system is designed for a water hardness of up to 50 °dH.

All-Around Water Protection
1. 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 regeneration chamber. If the inner hose should burst, the water,
passes into the regeneration chamber and over the safety overflow (5) and into the
base tray activating the float switch which energises the drain pump. This drains the
dishwasher preventing water damage.
2. 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.

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 point the water divides. 1/4 of
the water enters the tub through the vent (23). 3/4 of the water enters the sump (24) through
hose (6).
The level control chamber built into the sump operates the pressure switch (15).

Filling Steps
1. static fill level
2. timed fill 30 seconds
3. dynamic filling with circulation pump running (speed 2000 min-1 to level, maximum time
60 sec.)
Circulation
The circulation pump (17) pumps the water into the roof-mounted shower (22) and both spray
arms (21) simultaneously. The filters (16) filter the water and supply it to the circulation pump.
Pulsed wash action
After the filling steps the circulation pump runs at two speeds.
- 4 seconds with 1600 min-1
- 0,8 seconds with 2800 min-1
This new process increases the spray pressure in the dishwasher.
Advantages:
1. Reduced water consumption
2. Reduced energy consumption
3 Noise reduction

Pumping Out
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 (20) at the inlet connection to the drain pump (19). This
valve prevents the water running back from the drain hose into the dishwasher.

Installation of the Drain Hose
Drain hose connection:
Max. permissible height: 1 metre;
Min. height required 30 cm above floor level.
The drain hose can be extended horizontally to a maximum length of 3 metres, at a height of
85 cm.
Regeneration
The water chamber for regeneration (3) contains 350 ml water. During regeneration, the
regeneration valve (11) is energized. The 350 ml water runs into the salt container (9) and mixes
with the salt to form a brine solution.
In the top of the salt container there is an opening with a small filter, from here the brine solution
passes through a non-return valve (10) and enters the softener (8) where the resins are
regenerated.
The softener has 10 settings and can be adjusted to suit the degree of water hardness.
