OPERATION PRINCIP E
Traditional washing Operation
1 Detergent hatch
2 Hose between detergent dispenser and outer drum
3 Outer drum
4 Inner drum
- The partides of soiling substances which are freed from the textile fibres by the chemical action of the detergent
at the temperature of the washing water are re-moved by the flow of water through the fibres.
- The reversing rotation ofthe drum causes mechamcal interaction between the parts ofthe load and the
detergent solution which separates the partides from the textlies.
- The water level is at such a height that the load is successively lifted from the solution by the ridges formed
in the inner drum and then falls back into the solution.
- The Circulation ofthe solution during the rotation ofthe drum prevents the accumulation of detergent in the
rubber bottom.

Front hatch
The hatch is locked during washing by a bimetallic
electric hatch lock and is opened by depressmg the
hatch lock pad. When the hatch is closed and the
On/Off button is pressed, a Signal lamp Illuminates
after approximately 5 seconds, the hatch 1s locked
electrically and the selected washing cycle Starts.
When the program has been exe-cuted, the lamp
extinguishes after 45-120 seconds and the hatch
can be reopened.

Hatch locking switch
The security of the hatch is ensured by an electromagnetlc lock
with function äs described below.
 when the lock is activated, the voltage-sensing unit closes
the switch which con-nects voltage to the electrical
components of the machine.
 During operations, the slide (A) remains mechanically
locked and thereby prevents opening of the hatch by fixing
the hatch lock lever
 When the hatch lock has been deactivated, It remains
locked for approximately 45-120 seconds to ensure that
the drum is statlonary before the hatch is opened.

Programmed control unit
Imbalance control, f nction
A check for imbalance of the load 1s performed during 15 seconds at 85 rev/min. before the spin phase.
- If imbalance is detected, the tachometer generator and the motor current give an irregulär Signal
to the micro-processor on the electronics board which then Interrupts the spin phase. The
machine then returns to 55 rev/mm.. rotation and re-distributes the load to achieve balance
before performing a new check at 85 rev/min..
- If imbalance persists, redlstribution of the load is repeated for a period of 10 minutes (16
attempts) or until balance is achleved.
- If no balance is obtained after 10 minutes, the program continues forward with-outspln.
- When balance is obtained, the program continues with spin atthe speed speci-fied.
Monrtoring of spin phase for imbalance
This sequence is repeated while the
load remains unbalanced...
...a total of 16 times (10 minutes) or until
balance is achieved. if balance is not obtained,
the spin is omitted from the program.

Water supply valve
General characteristics
This electro-magnetic controlled valve regulates the supply of water
to the machine via the water distributor in the detergent distributor.
It 1s actuated by a solenold which is controlled electrically bythe
programmed Controller via the level regulator.
When the valve Is inactive, (without voltage) the spring holds the
splndle down and the rubber cone seals a small hole at the centre
of the membrane. A head of water bullds up which holds the
membrane against Its seating and closes the valve.
When voltage 1s applled to the solenold, the splndle with the rubber
cone is drawn up-ward against the spring and the hole in the
membrane 1s exposed, permitting the passage of water. The
pressure differential 1s lost and water can flow freely through the
valve.

evel regulator
General characteristics
The level regulator momtors the level of the water in the
machlne and
 adapts the water level to that required at different stages
ofthe washing sequence selected.
 acts äs a low-water safety device äs It is connected in
series with the heating ele-ment. It disconnects the
voltage to the element when the water falls below a
certaln level.
 acts äs an anti-foam protection by sending a Signal to
the electromcs which Interrupts the spln phase and
restarts this when the foam has subsided. (VE 60 and
V 60 program med Controllers).

Heating Element
General characteristics
The element for heating the water is of the
encapsulated type, i.e. the spiral resistor is
hermetically sealed in a stainless steel enclosure.
Power 1600 W
Resistance 230 V 31.2 - 34.3 Ohm
240 V 33.9 - 37.4 Ohm
1 Element
2 Rubber packing
3 Fixed f lange
4 Electrical connection pin
5 Locking nut
6 Adjustable f lange
7 Fuse
The seal between the element and the outer drum is
obtained with a rubber packing which expands when
the locking nut is tightened.
NTC-Thermistor (Temperature control)
Temperature control by means of NTC thermistors is incorporated in models
controlled by Programmed control units VA 60, VB 60 and VE 60.
NTC temperature sensors
1 Plastic housing
2 Metal capsule
3 NTC resistance
4 Electrical contacts
Table with resistance at different temperatures (3%)
Temperature °C Resistance kOhm
30 17.3
40 11.5
50 7.84
60 5.46
70 3.90
78 2.97
85 2.32
The temperature of the washing water is controlled by the microprocessor via an NTC sensor.
The internal resistance ofthe sensor decreases äs the temperature increases. This decrease is registered by the
microprocessor which disconnects the heating element when the required temperature has been reached.
With a short-circult or other failure in the NTC thermistor, the control unit cancels the heating stage and completes the
program without heating.

Drainage pump
1 Impeller
2 Rotor
3 Stator
4 Pump housing
5 0-ring
The rotor consists of a permanent magnet which can rotate clockwise or anti clock-wise. The rotor can
rotate one quarter revolution without movement ofthe impeller.
Ifthe impeller seizes, the rotor can therefore make small movements in both directions until the impeller
is freed. An unusual sound may be heard at Start which is quite normal.
Function check
1 Check that the impeller can move freely.
2 Check the resistance of the Stator winding. This should be 170 Ohm.
Max. capacity = 20 l/mm.
Power consumptlon = 30 W
