Until the temperature is reached, rinsing occurs in the bottom basket only. -
Page 7: Components
4.1.1 Regeneration electronics COMPONENTS The electronics determine, in comparison with the water hardness set Module on the appliance, the volume of water which is possible until the softening system is exhausted. The number of rinse cycles is counted. Regeneration then takes place once the maximum possible number of rinse cycles has been reached. - Page 8 4.1.5 Water supply The appliance realises that the tap is turned off if no signal is received from the flow sensor after 30 s. 4.1.6 Consumers The consumers such as the valves, the detergent and rinse aid dis- pensers and the circulation pump are actuated by triacs (see listing of triacs).

Page 10: Actuator
Actuator The thermohydraulic system consists of a metal cylinder with plunger. The cylinder is filled with a substance which expands greatly when heated. The heat source is a PTC (positive temperature coefficient) (1) which is in direct contact with the metal cylinder (4). A strong pressure spring (3) returns the plunger (6) back to its original position when the heat source is switched off. -
Page 11: Aqua Sensor (Optional)
48 programme structures are possible in the automatic programme. Aqua sensor (optional) In each programme sequence in which the Aqua sensor is active the sensor is also calbrated. If the calibration is defective, a fault is written to the fault memory of the module, the measurement is set to turbid and a maximum pro- gramme sequence occurs. -
Page 12: Aqua Stop Valve
Aqua Stop valve The Aqua Stop valve consists of two solenoid valves (A) in a row, the filler and safety valves. These valves are actuated in parallel. There are two filters on the screw connection for the tap. Under the filters is the flow limiter. -

Page 15: Salt And Rinse-Aid Indicators (Optional)
Salt and rinse-aid indicators (optional) The dispenser contains a float with an integrated permanent magnet (A). The magnetic field actuates a reed switch on the outside of the dispenser. The lamps of the refill indicators in the control panel are switched on via this reed switch. -
Page 16: Optical Low Rinse-Aid Sensor (Optional)
Optical low rinse-aid sensor (optional) The optical low rinse-aid sensor consists of a transmitter diode and a receiver diode. A light beam is transmitted from the transmitter diode (A) to the receiver diode (B) via a prism (C). If the dispenser is full, the light beam in the prism is scattered. -
Page 17: Dispenser
Dispenser Dosing plunger Magnetic float Switching core Reed contact (optional) Actuator Optical sensor (optional) The release mechanism is activated by an actuator (C). When the actuator is actuated for the first time, the detergent-dispenser cover is opened. At the same time the release pawl engages with the switching core (B) of the rinse-aid lever so that when the actuator (C) is activated again, the dosing plunger (A) is lifted off the rinse aid. -

Page 26: Level Sensor With Safety Function
If the dishwasher controller or components malfunction, causing the 4.18 Level sensor with safety function machine to overfill, the valve combination is closed via the safety system, shutting off the water supply. The drainage pump is switched on via the safety level switch (A). Pumping continues until the safety level switch (A) switches back again. -
Page 27: Water Inlet Without Heat Exchanger
Water inlet without heat exchanger When the filler valve has been opened, the water flows through the flow sensor towards the integrated inlet via a free flow channel and into the regeneration chamber. When the regeneration chamber has been filled, the water flows through the water softening system via the overflow channel and then flows as soft water into the pump sump. -
