Product Definition - Performance As a function of material, quantity and programme Pre-ironing -> for blouses, shirts, trousers, jackets, skirts, coats etc. from linen, cotton, synthetic for 0,5 to ca. 1 kg laundry, that do not have to be ironed in ideal case Refresh -> Usable with not-washable and not washed textiles, Removing of smells, folds and rough creases - possibly is later necessary a ironing, since e.g. also Bügelfalten are removed Iron aid -> for all materials because relatively even moisture distribution on and in the materials for 0,5 to ca. 3 kg laundry 15
Definition Drying Process Hot dry air Hot humid air Condensation Air inlet Exit 16
Air Ccirculation System The drying functionality is influenced by two air circulation systems. a warm air circuit which is sealed within the appliance a cold air circuit which circulates ambient air through certain sections of the appliance The warm air circuit removes the humidity from the clothes fabrics and crosses the cold air circuit inside of the heat exchanger. The result is a thermal exchange which condenses the humidity contained in the warm air. The condensation water is collected in a tank. 17
Humidity Sensing Conductimetric sensor: The two halves of the drum are separated by an insulating strip. The impedance of the front and rear shells ( to which the sensors are connected) varies according to the wash load, the type of fabric and the degree of humidity. This value is converted into an oscillation of 260Hz and 0Hz by the electronic. It determines the duration of the cycle and the final humidity. opened circuit : 0Hz closed circuit : 260Hz +/- 10% 18

Electric Test Mode Depending on Software configuration the machine will start the Electric test programme when switching on the appliance after Service mode. In this test programme all electrical components Will be activated. Because the power consumption would be too high for the CRM (3 heaters), the electric test mode is splitted in 2 test cycles. Programme selector in position 1 EL1: Dryer components active: Drum motor, fan motor, full heating and condensation pump Programme selector in position 2 EL2: CRM components active: Steam heating and steam pump 61
Alarm Management In User Mode 1. Buzzer sounds for alarms which are shown to the customer only (E20, E40, excepted EB0) 2. Buzzer sounds with a specific sequence of three short beeps about every 20 seconds (for TC1 appliances a special jingle will be played for warnings) 3. In case of alarm the red Start/Pause LED flashes as long as the fault condition is present (0,5s on, 0,5s off) 4. For TC1 appliances with graphic LCD display the warnings will be shown as text messages 62
Alarm Management In User Mode Fast alarm reading is possible like in the present washing machine range by pressing the standard key combination about 2 seconds. 63
Alarm Management In Service Mode 1. Turn the programme selector to the alarm memory position 2. Red and green LEDs integrated in Start/Pause key flash alternated according to alarmn code: - Red LED shows the alarm family code (E42 4 times) - Green LED shows the alarm number (E42 2 times) 3. Alarm will be shown completely in time to end display, if LCD display available (example: E42) 4. For graphic LCD user interfaces (TC1) a specific customer screen with complete alarm code and possible supplementary text descriptions can be shown 5. Delete the alarm memory by pressing standard key combination 64
Alarm Management In Service Mode Attention: It s possible to read the last three alarm codes in the alarm memory by pressing a key combination simultaneously. ( Solution still under development ) 65
