3.2 Door sensor

3.2.1 Position of the door sensor

1 Door sensor (Hall element) 2 Screw connection for door sensor

The door sensor is situated in the centre at the top of the inner door. A permanent magnet is inserted in the door lock

3.2.2 Function of the door sensor

Hall sensors (also known as Hall probes, after Edwin Hall) use the Hall effect to measure magnetic fields. When the door is closed, the permanent magnet is positioned exactly over the Hall sensor. When the door is opened or closed, the strength of the magnetic field changes on the Hall sensor. The Hall sensor modifies its power input. The electronics detect whether the door is open or closed. If the power input is outside a defined range, this is detected by the electronics as a fault. The Hall sensor responds to the direction of the magnetic field. An incorrectly fitted permanent magnet or incorrectly polarised signal lines may result in wrong information being sent to the electronics.


3.3 Door lock

3.3.1 Overall view of the mechanical door lock

1 Door lock 3 Mechanical snap lock

2 Mechanical childproof lock (optional) 4 Permanent magnet

The door lock is mechanical. A snap lock in the container frame engages in a recess in the door frame.

3.3.2 Function of the mechanical childproof lock (optional)

The mechanical childproof lock prevents the door from opening. Activation: Pull lever outwards and push to the right. Deactivation: Push lever all the way in.


3.4 Childproof lock

3.4.1 Electronic door lock (optional)

The appliance can be secured to prevent programmes from being ended unintentionally (e.g. faulty operation by children).

Activating button lock: Start the required programme. Hold down button B for approx. 4 sec. until CL is indicated on the digital display. If any button is pressed while the programme is running, CL is dis-played. The programme cannot be ended (reset).

Deactivating button lock: Hold down button B for approx. 4 sec. until CL goes out. When the programme ends (on the digital display), the button lock is cancelled. If there is a power failure, the button lock is retained. Whenever a programme is started, the button lock must be re-activated


3.5 Aquastop valve

3.5.1 Design

The Aquastop valve is an electromechanical safety valve. The coarse and fine filters are located on the screw connection for the tap. Under the filters is the flow limiter. It limits the water flow to 2.5 litres. The Aquastop valve is enclosed by a housing. A leakage water hose (external hose –> jacket around the supply hose) runs from the housing into the base pan. The leakage water hose contains the water supply hose and the electric control cable for the solenoid valve.

3.5.2 Function

In the idle state the coil is de-energised and the seal interrupts the water flow by the effect of the spring which presses on the armature. If the Aquastop valve is connected to the water mains, the water pressure also acts from behind on the seal and supports the sealing. If leaks occur in the area of the valve or supply hose, these are conveyed into the base pan via the leakage water hose. A polystyrene float activates the electronic safety system via a micro-switch. The coil of the AquaStop valve is deactivated by the elec-tronics and interrupts the flow of water into the appliance.

3.6 Water inlet valve

3.6.1 Design

The water inlet valve is an electromechanical safety valve. The supply hose is attached from the screw connection on the tap to the water inlet valve. The coarse filter is on the screw connection for the tap. Under the filter is the flow limiter. It limits the water flow to 2.5 litres. The water inlet valve is controlled via the electronics.

1 Coarse filter 6 Coil 2 Union nut 7 Seal 3 Pressure hose – water supply 8 Flow limiter 4 Retaining plate 9 Pressure hose – water supply 5 Connector


3.7 Water inlet

When the programme starts, the electronic control opens the Aquastop/water inlet valve (filling valve) for a short time. It is expected that water runs in. Electronics evaluates the impulses of the rotating flow sensor. Are these missing, an error code is indicated, the water tap LED flash and the program does not start. If impulses are received, the program starts. The drain valve is activated and the content of the heat exchanger is discharged into the container. By launching the circulation pump a smooth running filling starts. Is recognized that too little water is in the equipment, the AquaStop- / water inlet valve is opened. Water flows into the heat exchanger via the supply hose. The flow sensor and the free flow line are located in the water channel of the heat exchanger for the water supply. The water flows either into the granulate container (soften) or into the salt container (regenerate) via the regeneration valve in the water softening system. The outlet opening of the water softening system conveys the water back to the heat exchanger.

3.7.1 Bithermal connection (optional)

Appliances with bithermal water connection have 2 supply hoses with AquaStop valve. The colour of the AquaStop valve identifies the difference between cold and hot water connections. The electronics control both valves separately. The appliance is supplied with either cold water or hot water.

1 Free flow line 7 Impeller wheel with flow sensor 2 Heat exchanger drainage valve 8 Supply hoses 3 Water softening system 9 AquaStop valve for hot water

4 Regeneration valve 10 AquaStop valve for cold water, optionally water inlet valve

5 Outlet opening 11 Heat exchanger water channel 6 Mixing piece


3.7.2 Appliances with liquor reservoir (optional)

If the appliance has an optional liquor reservoir, the heat exchanger at the end of the final rinse is filled only to 2/3 (2.1 l). This results in an amount of water of approx. 4.2 l in the appliance.


3.8 Heat exchanger

The heat exchanger is used as the water inlet, water outlet and for storing the water which exchanges the heat. The diagram shows the components and connections of the heat exchanger.

1 Free flow line 7 Inlet from detergent-solution pump 2 Heat exchanger drainage valve 8 Water drainage (to the siphon) 3 Water drainage to the rinsing tank 9 Flow sensor 4 Inlet from water softening system 10 Expansion opening

5 Water outlet to the water softening system 11 Drainage hose ventilation valve

6 Water supply 12 Barrier


3.9 Expansion opening

The heat exchanger is connected to the rinsing tank by the expansion opening. During the heating process the air in the rinsing tank expands. To pre-vent an overpressure and to ensure that the door is pressed on, air escapes via the expansion opening. If the door is opened while the washed utensils are warm, cold air flows into the appliance. If the door is closed, the air is heated by the warm washed utensils and expands. Overpressure occurs. This overpressure is released via the expansion opening onto the heat exchanger where it is dissipated via a small air hole.

1 Expansion opening in heat exchanger


3.10 Low salt detection

The PCB for the low salt indicator is attached with clips to the right side of the water softening system (front side of appliance).

The salt level is detected via a light barrier. If the regeneration salt runs low, the line in the light barrier is freed and the electronics detect “Add salt”.

If the low salt indicator appears, there is still so much salt in the appliance that some more regeneration processes may occur.

According to this principle it is not necessary to fill the salt dispenser with water when switching on the appliance for the first time.

It is filled with salt tablets is recognized only with a water softening system with a float.

1 Photodiode 3 Transmitter LED

2 Regeneration salt


3.11 Water switch

The water switch controls the water passage of the 3 spray levels and the filling of the optional water storage tank. It consists of a drive motor with cam plate, pulse generator and the locking disc. When the appliance is switched on, the motor is actuated via a triac. The cam plate is attached to the motor axle. The cam plate actuates a switch (pulse generator) which transmits pulses of different length and intervals to the electronics. If the electronics detect the standard setting, the water switch is initialised. The locking disc is rotated depending on the actuation. In doing so, holes of varying size release the water passage on the particular spray level or the connection of the hose to the optional water storage tank. The arrangement of the openings in the locking plate allows several levels to be actuated simultaneously or alternately.

3 Pulse generator (switch) 7 Connection water storage tank (optionally)

4 Drive motor


3.12 Ventilation sequence

1 Input water outlet 4 Float chamber 2 Output water outlet 5 Float 3 Air duct 6 Ventilation opening

During pumping, water is pumped to the drainage hose via the drainage channel of the heat exchanger / water inlet. A continuous water flow occurs. If the drainage is lower than the appliance, the water flows out of the appliance by suction effect even if the drain pump is no longer actuated. In the float chamber there is so much water that the float floats and the ventilation opening closes. The ventilation opening is released by the float as soon as the water flow in the water outlet decreases. The appliance cannot be drained while the liquor pump is deactivated as air can flow in via the ventilation opening. If the drainage hose is defective (blockage, kink), pressure builds up.

Electronics detects the blockage over by drain pump An error code is saved in the failure memory.


3.13 Variable hinge

3.13.1 Description

The variable hinge enables fully integrated dishwashers to be installed in kitchens with a low base. The device moves the decor front upwards when the door is opened. As a result, the overhang at the bottom is smaller and passes over the base. The gap between the base and furniture door can be reduced. If appliances are installed higher, the visual appearance is significantly improved.


3.14 Emotion light (optionally)

Emotion light is an internal light.

If the “Emotion Light” function is activated in the appliance menu, 2 LEDs light up when the door is opened. The interior light (Emotion Light) comes on when the door is opened irrespective of whether the ON/OFF switch is switched on or off. When the door is closed the light is off. If the door is open for longer than 60 min., the light switches off automatically. The interior light is lit only when the set value P:00 is selected.

Fault Possible cause Fault correction Advise customer Scratches or break. Scratches caused by contact points/surfaces

with other utensils. Avoid contact points when loading

the dishwasher. Utensils faded. Utensils not dishwasher-proof. Use dishwasher-proof utensils. Rust on the cutlery. Cutlery corrosion: Cutlery not dishwasher-

proof (knives/knife blade steel is usually less corrosion-resistant).

Use dishwasher-proof cutlery! (higher chromium/nickel content, at least 18/8 or 18/10).

Airborne rust: Infection caused by corroding utensils or utensil basket.

Do not wash rusting utensils, such as an old pan, in the dishwasher!

Rust on the container (pitting corrosion).

Washing was not started immediately after salt was topped up. Salt causes pitting corrosion on the detergent-solution container.

To prevent corrosion, always refill with salt immediately before switching on the appliance.


Drying result poor

Unloading the dishwasher.

Droplet formation on the underside of the utensils and on the utensil or cutlery basket cannot be completely avoided.

• Always start with the bottom basket. Then unload the top basket followed by the cutlery drawer.

Note: Droplet formation on the underside of the utensils and on the utensil or cutlery basket cannot be completely avoided. • Wait until programme ends to

allow adequate drying. Recommendation: Remove utensils approx. 30 min. after programme ends.

Long standing times. When the specific heat of the utensils has been given off, the drying effect is reversed. The humidity in the appliance condenses again on the cooled utensils, resulting in droplet formation.

Long standing times with closed door (e.g. over night) are to be avoided after the rinse cycle. Recommendation: Remove utensils approx. 30 min. after programme ends.


Drying result poor

Fault Possible cause Fault correction Advise customer Combination detergent. Combination detergents (“5 in 1”, “7 in 1”,

etc.) do not always give an adequate drying result.

Recommend use of separate brand-name products. In addition to the tablets, rinse aid should be dosed. Many appliances are able to improve their drying performance by activation of the special drying option (see instructions for use).

Rinse aid. Rinse-aid dosage too low. Activation can be checked in the test programme (number of pulses = dosage setting). The magnet must activate as frequently as required.

• Top up rinse aid. • Activate rinse aid dosing or

increase setting. • Eco rinse aids are available on

the market but their drying properties are inferior to those of normal rinse aid.

• It is recommended to switch to traditional brand-name products.

• If “3 in 1” products are used, rinse aid setting not moved to “0” no aut. Programme optimisation in “3 in 1” mode.

Plug for low rinse-aid sensor not inserted correctly. Consequence: Low rinse aid is not indicated. Customer does not top it up. If “3 in 1” products are used, the customer does not move the rinse aid setting to “0” (because indicator is not malfunctioning) no automat. Programme optimisation in “3 in 1” mode.

Low rinse-aid indicator/Check low rinse-aid sensor.


Drying result poor

Fault Possible cause Fault correction Advise customer Programme selection. • Programme selected without drying phase. (Short rinse programmes, e.g.

“Quick”, have no or a very short drying phase).

• Using the “Vario-Speed” function. Drying time reduced considerably and final rinse temperature increased. A slight impairment of the drying performance is unavoidable.

Plastic utensils. Due to the low heat storage capacity and the water-repellent surface, there may still be water droplets on plastic utensils after the drying cycle.

Some appliances are able to improve their drying performance by activation of the special drying option (see instructions for use). Note: Increase rinse-aid dosage.

Water supply. Angle valve calcified. Have installation checked by a fitter.

Supply hose kinked. When installing the appliance, ensure that the supply hose is installed correctly.

Aquastop/feed valve flow too low? • Check filter for soiling and, if required, clean.

• Check flow rate of the valve and, if required, replace.

Heat exchanger drainage valve leaking. Heat exchanger is drained between the wash and final rinse cycles too little water in final rinse cycle utensils not adequately heated in drying cycle. Note: No concentricity detected in the final rinse cycle, therefore any low water level not detected.

Check drainage valve for leaks.


Fault Possible cause Fault correction Advise customer Heater. Appliance does not heat up.

There must be adequate water in the appliance before the heating pump can heat the water to the required temperature.

• Check heating pump. • Check water supply.

Other causes. Heat exchanger not correctly locked is not situated adequately on the container smaller condensation area less cooling of the container side in the drying cycle.

Check fixing and catch mechanism.

Water in bottom of cups/glasses. Depending on the utensils and the loading characteristics, the sloping position of the cups may be too low. Water cannot drain.

Droplets on container/inner door. On account of the “Condensation drying” drying principle, water droplets are physically induced and required on the container. The humidity in the air condenses on the inner walls of the dishwasher, drains and is pumped out.
