Mechanical and electrical design 20 General Fig. 37 These machines are free-swinging models i.e. the outer drum and motor bridge are suspended in the machine chassis via a spring suspension with a strong spring in each corner of the machine. Each spring has a shock absorber which dampens the movement of the machine. The inner drum is driven by a motor via a V-belt: one motor is used washing and distribution speed and for extract speeds.
Mechanical and electrical design The washing machines are controlled by a microprocessor program unit. This provides several major advantages: • The control of times, levels and temperatures takes place with considerable precision and flexibility • The large character display provides detailed information in clear text about the different wash programs, the machine's different activities, relevant wash times and temperatures.
Mechanical and electrical design 22 Frame Description Fig. 38 The frame is constructed on the free-swinging principle, i.e. the washing drum is freely and resiliently suspended in the fixed frame. The entire frame is constructed of U-shaped iron beams forming a stable and torsionally rigid structure. The suspension device for the drum unit and motors consists of four posts, one in each corner, each with a robust spring to which the washing drum supports are attached.
Mechanical and electrical design 23 Drum with bearings Description Fig. 39 The inner drum is journalled to the outer drum by two robust bearings in a bearing housing which is bolted to the rear plate. The bearing unit supports the drum without any support being needed at the front. Shaft seals of the V-type, as well as O-rings, seal against leakage. The space between the bearings is packed with grease during assembly. No additional grease is required.
Mechanical and electrical design 24 Safety locking device The machine safety locking device includes a safety interlock system which prevents personal injury through the following precautions: • The machine cannot be started until the door is shut. • The door is automatically locked when the machine starts. • It is not possible to open the door until 2-3 minutes have elapsed after the washing program has ended. This ensures that the drum is motionless when the door is opened.
Mechanical and electrical design 25 Rotation guard Description The rotation guard checks that the machine is completely at a standstill before the door can be opened. When the drum has been at a standstill for approx. two seconds the solenoid in the door lock is deactivated and the lock can be opened (provided that the machine has been emptied of water and the programmer has reset). The rotation guard also checks that the drum is revolving when the wash or extraction relays are operating. Fig.
Mechanical and electrical design 26 Fault location Door does not unlock Conditions: wash program ended and drum at a standstill Measure the voltage between the following points: 1. X93:2 - X93:3 Should be 0 V DC. If the voltage is 220 V AC, check the rotation guard. 2. X193:1 - X193:2 Should be 0 V DC. If the voltage is 220 V AC, check the rotation guard and the cables between rotation guard and delay unit. 3. X194:1 - X194:4 Should be 220 V AC.
Mechanical and electrical design 27 Function If the machine has not been energised within the last three minutes, the door will remain unlocked. When the machine is energised the door will be locked if a program is activated or if the drum is rotating. Upon completion of a program the door will be unlocked automatically as soon as the drum has stopped rotating.
Mechanical and electrical design 28 Control unit The control panel (1), mounted at the front, includes all components necessary for operating the machine, such as display window, control switches and a key-operated switch. Fig. 43 The printed circuit board with the microprocessor electronic timer is mounted just behind the control panel.

Mechanical and electrical design 29 44 Relays The FC models employ relays to control the following: • switching between powder and liquid detergent. • drain to tank. • pump from tank. } for optional recovery and recycling • motor operation. Construction Fig. 44 The body of the relay holding the stationary contacts is made of current-resistant plastic. A solenoid and a contact bank hold the moving contacts. The contacts are spring-loaded to assure the correct contact pressure.
Mechanical and electrical design 30 Motor In machines with frequency control the same motor is used for wash speed, distribution speed and extraction. The motor is located on a motor mounting plate, and drives the drum via a belt. The tension of this drive belt can be altered by moving the entire motor mounting plate thanks to the mounting slots on one side. The motor has a thermal cut-out located in its windings.
Mechanical and electrical design Program start 31 46 The following conditions must be fullfilled before the motor can start: High extraction • Motor not overloaded. • Door shut. • Go-ahead signal from programmer. When the door is locked relay K71 is activated feeding power to the electronic control unit and the motor is allowed to start. Extraction Fig. 46 For extraction the programmer sends signals for either low or high extraction.
Mechanical and electrical design 32 Repair instructions 47 Overheated motor, motor not running • Wait till motor has cooled down. Motor guards are automatically reset after 30 minutes. Restart. • Possible cause of motor guards releasing repeatedly: short circuiting. In both cases the motor should be replaced. A Very noisy motor • Breakdown of bearings – replace motor.
Mechanical and electrical design Fig. 33 Loosen the screws holding the motor mounting plate on the motor side. Lower the motor mounting plate until the correct belt tension is obtained, as shown in Fig. 45. Secure the motor mounting plate in place. 47 Motor control On the motor control circuit board there is a yellow LED which indicates various types of fault: Fig. 48 48 4 1 Fuse XM1 3 6 1 XM4 2 (XM6) (XM3) 8 XM2 1 LED for error indication (XM5) Indication Cause The LED flickers.
Mechanical and electrical design 34 In two cases the machine will be halted without indication: • Overvoltage in feed. • Motor and/or motor control overheated. Motor does not operate when it should • Check the voltage feed to the motor control unit by: - Disconnecting XM4 (quick connector) - Using a voltmeter (AC) to measure between pins XM4:1-2. Correct value = 220 V (208 - 240 V) - Using a voltmeter (DC) to measure between pins XM6:1-4. Correct value = 250 - 375 V. If not check fuse. Replace unit.
Mechanical and electrical design Supply injection valve 35 49 Construction Fig. 49 This valve has a single-inlet with three outlets, each with its own solenoid coil. The body is made of heat-resistant polyamid plastic and the solenoids encased in water-tight plastic. The electrical connector terminals are spade lugs. A filter screen on the inlet side prevents dirt from entering the valve. Flow restrictors can be placed at either the inlet or any of the outlets. Operation Fig.
36 Mechanical and electrical design Repair instructions 51 Limescale can block the hole in the valve diaphragm and interfere with the function of the valve. Fig. 51 It is therefore advisable to dismantle and clean the valve at certain regular intervals. The frequency depends on operating conditions and the level of contamination in the water. If the valve does not open • Check that power is supplied to the coil.
Mechanical and electrical design Inlet valve - EX22 Fig. 54 37 54 The water inlets have brass bodies with a larger cross section of the outlet in order to acheive a shorter filling time for the machine. Construction The valve housing is made of pressed brass. The spring-loaded plunger is made of stainless steel and located at its lower end is a rubber gasket for the pilot valve.
Mechanical and electrical design 38 Soap supply box Fig. 57 The three-compartment soap supply box is located at the top of the machine. Viewed from the front, the compartments are marked with figures 1, 2 and 3. Compartment 1 and 2 are used for adding detergent directly to the wash. Compartment 3 is used for adding fabric softener. All three compartments can be programmed individually. For liquid supplies compartment 2 is only used together with a top mounted supply injector connection.
Mechanical and electrical design Drain valve 39 58 Description Fig. 58 The drain valve consists of a bracket (1), on which are mounted the motor and gear (2) and diaphragm (3). The rubber diaphragm is resistant to a water temperature up to 100°C (212•F). The installation of a lint trap is not necessary. The machine is equipped with an overflow, which bypasses the drain valve. The drain can be cleaned by removing the drain connection (4) outside of the machine or by removing the rubber diaphragm (3).
