2 = N3 = impulse electronic4 = L5 = electronic J1-2

When closing the lid the door lock gets an impulse from the electronic by contact 3. The impulse feedsthe magnetic coil over the PTC resistor. This moves the lever down and the tooth lock washer isforwarded by another tooth. This can be heard by a click. The locking part is unlocked, the lid is closed.

When opening the lid, e.g. with the start/pause button or at the end of the cycle, the door lock gets twoimpulses from the electronic. The tooth lock washer is moved twice. Only because of the second impulsethe lid can be opened immediately.The second impulse unlocks the locking part mechanically through the tooth lock washer.Why two impulses?The door lock is controlled by a triac which is on the main circuit board. If there is a triac short circuit, theelectronic sends an impulse to the door lock. The customer could open the appliance, if the secondimpulse was not required.

If there is a power failure during a wash cycle, the door lock requires approx. 2 min until the lid can beopened. During this time the PTC bimetal cools down and the locking part opens.

DSP (Drum-Self-Position)

Control ( check ) the DSP-Function:

1. Remove the side panel, switch on the appliance- Turn the drum to the right position ---> LED on- Turn the drum over the right position ---> LED off

2 Remove the two plugs from the DSP and checkthe resitance of the reed relay.- Turn the drum to the right position ---> > 0Ω- Turn the drum over the right position ---> 0Ω

3 The drum is still in the right position.Now measure the voltage. 5-6V DC- If there is no voltage ---> Cable,

Main electronic boardis defective

4. Check the In / Output electronic in the customersservice test program.- LED on ---> In / Output electronic OK.- LED off ---> In / Output electronic defective.

Function:The reed relay is closed if the metalic sheet, located on the pully, isn't between the magnet and the reedrelay. If the position of the metalic sheet is between those parts the contact of the reed relay is opened.

To mount the pulley in the correct way, you have to take care about following items:The metal sheet located on the pulley should be in the drum self positioning device, if the door of thedrum is in the upper postion. The DSP is supplied with 5-6 V DC by the main board.

Condition drum positioned:Reed contact opened, LED-Drum positioned illuminated, 5-6V DC.Condition drum out of postion:Reed contact closed, LED-Drum positioned not illuminated, 0V.

If the washing cycle is interrupted by the start pause button the drum has to be postioned within 10 sec.During this time 2-3 attempts can be excecuted.If the drum isn't positioned during this time, the lid of theappliance is released and can be opened. The LED drum positioned is not illuminated.At the end of the cycle the positioning phase is 2 min until time out is reached.

Inlet valve with flow-meter-sensor

Depending on the type of appliance, the automatic washer can be equipped with a 2-fold inlet valve withor without flow-meter-sensor.

Function:The inlet valve includes a flow meter sensor. The flow meter sensor emits electrical pulses of 5V to themain electronic. This is enabled by a magnet which opens and shuts a reed contact. The magnet islocated on a movable turbine 2. Because of the water pressure the turbine rotates and thus givesimpulses to the main electronic. The water pressure of > 1 bar is limited by the volume regulator to 5.5 l/min +15%/-15%.(see Page Service - Program fault display EC0)

Float switch

The float switch is made of a housing with a microswitch and a float body.

Function:The float switch is located in the bottom tray. Thebottom tray is constructed in a way that the water isgathering in the area of the float switch in case ofleaky components (tub, hoses, etc.). The float bodycomes up and switches a micro switch.This selects the drain pump, the existing water inthe tub is drained. The inlet valve is switched off.

Analogic pressure switch

The analogic pressure switch controls the water level in the tub, it is directly connected to the electronicmodul.

If the pressure switch does not work correctly, the programm in progress is cancelled:

1. Pressure switch hose connection2. Diaphragm3. Coil (self)4. Electronic circuit (oscillator)5. Magnet6. Spring7. Adjusting screw8. Connector

Kontakt 1 = OutKontakt 2 = GNDKontakt 3 = 5V DC

When the tub is full, the pressure inside the hydraulic circuit acts on the diaphragm which moves themagnet insidethe coil.

This moving modifies the inductance of self and consequently the frequence delivered by the scillatorycircuit. the μP, after frequence reading, recognizes the water level inside the tub. (see Page Service -Program fault display E30)

Frequence delivered follow the pressure (± 50 Hz)


Connection: 230V; 50Hz;Power: 1950WFuse: 10A

Heating element

The heating element is supplied with power directly from the controlelectronics by means of a relay. For security reasons, 2 switchingcontacts of the pressure switch are connected in series. Theswitching positions are monitored by control electronics via 2 controllines.

1. Heating element2. Temperature fuse3. NTC-sensor4. Connection

Check of insulation resistance with the heating

Wash a cycle for approx. 10 minutes. Switch off the appliance, unplugthe plug and remove the side panel.Draw off the connecting lines from the heater.Measure the resistance between heating (depending on connection)and mass.Resistance > 200 kOhm —> heater OK.Resistance < 168 kOhm —> error E68


Heating Circuit

The cycle temperature is fixed by the μP depending on the selected program.The temperature control is guaranteed by the μP through the NTC temperature sensor. The temperaturesensor reduces its resistance according to the temperature increase.The reduction in the ohmio value of the temperature sensor is detected by the μP; as soon as theselected temperature is reached the power supply to the heating element will be paused.The NTC sensor is integrated in the heating element.

Variations of NTC resistance

Temperature (°C) Resistance (Ohm)25 4815 +- 20740 2563 +- 102,560 1196 +- 26,3180 602 +- 19,89

NTC-Sensor

1. NTC resistance2. Metallic casing3. Connections4. Plastic casing

To check the NTC sensor function you can measure the ohmic resistance between the contacts J9/8 and J9/9.

Security

- The μP will be break off if an anomaly on the termistance circuit is detected :cut or short-circuit. (see Page Service-Program fault display E70)

- The heating phase is not executed.


Drain pump / Circulation pump

The drain pump and circulation pump is directly controlled via triac from the control electronics.

Connection:

Motor

Electronic EWM2100

The motor is directly phase-controlled via triac from the control electronics.Relays K2, K3 are responsible for commuting the sense of rotation.Field switching (if any) is controlled by relay K4.Speed is monitored by tachometer generator g1 and controlled by control electronics.Integral overheat protection disconnects the motor from power supply at 115°C.

Safety- If the triac for the motor is in short-circuit, or if the tachometer generator is interrupted, 4 trials are

executed in intervals of 5 minute each.After a break of 20 minutes, the fifth and last trial is started. If the motor does not run this time, theprogramme is aborted.(see Page Service-Program fault display E60)


Motor, Motor control board

Electronic EWM2500

These appliances include a 2-pin asynchronous three-phase motor. This motor is directly driven by aspecial inverter motor electronic system. This changes the frequencies of the rotary current inaccordance with the required rotational speed. The motor electronic system is connected with the controlelectronic system via a control line.

Connection:

The ohmic resistance of the tacho generatoramounts to approx. 119 Ohms. The measurableresistance of the motor coils can be measuredbetween the connection contacts of motorsm4-m5 / m4-m6 / m5-m6 and amount toapprox. 5.5 Ohms in each case. The phase shiftbetween the phases is 120° and peak amplitudeis 310V.

Safety- If the transistor for the motor is in short-circuit, or if the tachometer generator is interrupted, 4 trials

are executed in intervals of 5 minute each.After a break of 20 minutes, the fifth and last trial is started. If the motor does not run this time, theprogramme is aborted.(see Page Service-Program fault display E50)

1/min

Perfect balance

- Reversing- FUCS phase 0

with spin-dry pulse- Reversing- FUCS phase 1- regular spin-dry

Function of the FUCS

“FUCS” is an English expression and means “Fast Unbalanced Control System”

Function:The unbalance control includes 4 phases. These phases are of different duration and have different limitsof unbalance. The magnitude of the unbalance is calculated every 300 ms, hereby the magnitude iscompared to the fixed unbalance limits, and then it is decided whether the speed will be increased orreduced by 2 1/min. FUCS starts at 55 1/min and ends ideally when reaching 115 1/min.

Phase 0: When the unbalance threshold (850gr.) of the first phase is reached, the appliance performsa spin cycle with 100 1/min for 5 sec followed by a spin cycle pulse of 470 1/min.

Phase 1: The first phase (350gr.) takes max. 120 sec to obtain the required speed of 115 1/min. If thespeed is not reached after this 120 sec, the spinning cycle will be stopped. The laundry isdispersed and it is changed to phase 2.

Phase 2: Phase 2 (650gr.) takes max. 60 sec. Here it is tried to obtain the speed of 115 1/min withvarious unbalance limits. If the speed is not reached after 60 sec, the spinning cycle will bestopped again. The laundry is dispersed and it is changed to phase 3.

Phase 3: In phase 3 (1100gr.), the required speed is reduced to 85 1/min. Within 90 sec, speed shouldbe reached, the machine then runs a spin-dry cycle at 100 1/min for 5 sec.and a subsequentspin-dry pulse at 470 1/min, then again starting by phase 1. If the speed is reached, areduced spin-dry cycle at 650 1/min is carried out. If the speed is not reached, spin-dry isskipped.


Balancing after two attempts

- Low speed- FUCS phase 0- FUCS phase 1- FUCS phase 2

Balancing after the third phase (normal spin-speed)

- FUCS phase 0with spin pulse

- FUCS phase 1- FUCS phase 2- FUCS phase 3

with spin pulse- FUCS phase 1- FUCS phase 2- FUCS phase 3- Normal spin

Balancing after the third phase (reduced spin-speed)

- FUCS phase 0- FUCS phase 1- FUCS phase 2- FUCS phase 3

with spin pulse- FUCS phase 1- FUCS phase 2- FUCS phase 3- reduced-speed spin

Unalancing after the third phase

- FUCS phase 0- FUCS phase 1- FUCS phase 2- FUCS phase 3- FUCS phase 1- FUCS phase 2- FUCS phase 3- no spin

Foam Detection

Anti-foam control is excited via analog pressure switch.

Anti-Foam

Spin-dry phase without foam: Spin-dry phase with little foam:

Spin-dry with little foam:

When the analogous pressure switch detects foam (45 mm “full”), the spinning cycle is stoppedand the drain pump keeps on running until the foam level will be fallen below (15 mm “empty”) andthe spinning cycle is continued.

Spin-dry with excess foam:

When the analogous pressure switch detects a foam 5 times (45 mm “full”), the spinning will beskipped. Draining is carried out for 1 minute with the motor at stop. If too much foam is detectedduring any wash cycle, an additional rinse cycle is added.

Service Program

Rapid reading of alarm codes

The last alarm code can be displayed even if the programme selector is not in the 10th position(service test mode) or if the appliance is in normal operating mode (e.g. during the execution of anwashing programme):

- Keep buttons 6 and 5 pressed in together.

- The alarm sequence continues as long as the two buttons are held down

- While the alarms are displayed, the appliance continues to perform the cycle or, if in theprogramme selection phase, maintains the previously-selected options in memory.

Indication of error code through LEDs

The error code is additionally indicated by the START/PAUSE LED.The START/PAUSE LED is a double LED with colors red and green.When the red LED is flashing (0.5 sec on, 0.5 sec off), the alarm family will be indicated, when the greenLED is flashing afterwards, the alarm number will be indicated.

e.g. EA4

- EA4 ---> red LED flashes 10 x

- pause of 1.5 sec

- EA4 ---> green LED flashes 4 x

- pause of 2.5 sec, then repetition

Cancelling the last alarm

- Enter service test program (page 37)

- Press buttons 6 and 5 in together and keep them pressed in until the LCD E00.

It is good practice to cancel the last alarm:

- after reading the alarm code, to check whether the alarm re-occurs during diagnostics

- after repairing the appliance, to check whether it re-occurs during testing.
