INTRODUCTION
1 - INTRODUCTION
The objective is simple : the matter is to make the dirty laundry clean. The quantity, nature, dirt level of
the laundry, the cleaning product used, or even the water hardness may act against the expected
result.
So far, all these parameters have been left to the assessment of the consumer, who alone assumed
the responsibility for poor wash. Increasingly, the new washing machines consider all these factors and
adapt :
The mixing duration in wash
•
The quantity of water and the number of rinses
•
The spin duration
•
The new top loading washing machine provides reduction in water, energy consumption, and cycle
times while assuring A level in wash.
To perform the washing machine maintenance, the technician has to identify the cause(s) at the origin
of the consumer's claim. To do so, he/she has to make a precise diagnostic in order to adopt the
appropriate for the encountered problem.
The new top loading washing machine proposes a programme of aid to diagnostic intended for the
after-sales department. Only the rigorous and systematic implementation of this programme can
definitely assure the action reliability.
A properly performed after-sales action should favour the development of customer’s loyalty to the
sales outlet, to the sign and also to the trademark concerned.

2.1. - What you must know
Washing machine, dryer and dishwasher are three
appliances likely to weigh heavy on the electricity invoice if
you choose model poorly classified from the energetic
point of view. Washing machine and dishwasher each
consume about 250 kWh a year. For a few years, the
manufacturers have made efforts on the water
consumption, which has a direct effect on the power
consumption at the moment of the heating.
Initiated by the European Community, this labelling is now
compulsory in France for most household electrical
appliances. The classification from A (the most
economical) to G (the most avid on electricity), enables
the consumer to locate at a glance, the various models
proposed. For washing machines, an additional indication
concerning the wash and spin, complements the
information concerning the power consumed.
This mention must appear compulsorily on all the washing
machines marketed from the 1
st
of January 1999.

3 - THE WASHING MACHINE
3.1. - Operating principle
Dirt adheres the textile fibres with some energy to be overcome in order to get rid of it. It is, therefore,
necessary to implement the following parameters :
The mechanical action
¾
The role of the mechanical action is to make the water loaded with detergent product circulate between
laundry fibres in order to enable dirt to be detached and carried away. This
action depends on the stirring duration and rotation rate and speed (from 35
to 50 rpm), and on the water level in the tank.
The thermal action
¾
Some fibres are to be washed at maximum temperatures not to be exceeded
if you want to obtain good results. Moreover, the action of the various
components of detergent products vary according to the temperature. For this
purpose, the washing bath will be heated progressively, so that each of these
components is more efficient.
The chemical action
¾
To the mechanical and thermal energy of the machine are added the
detergent physical-chemical and biological actions. The nature of dirt is most
varied. Each of the kinds of dirt is eliminated in a specific way. This is the
reason why washing products contain from 8 to 15 different components.
So, it is advisable to act on the washing conditions in order to facilitate the
quick removal of the various matters.
The duration.
¾
Everything is not so simple. If we detail the operation, then we notice that an essential element is
missing: the Water. In fact, without water, there is no wash. Water is primordial; with the support of the
active principles of the washing product, it will penetrate the depths of the laundry to destroy, extract,
dissolve and emulsify the dirt present on and within the laundry. It will do it all the best that the machine
will mix the laundry and heat the water.
The wash result depends thus on 4 factors simultaneously :
•
The washing product
•
The water
•
The temperature
•
The mechanics
These factors are interrelated. If you decrease the dose of washing product for example, then it will be
necessary to increase either the mixing (mechanical action and duration), or the temperature (thermal
action), or the volume of water. A good wash result can only be obtained if all these conditions are
respected.
The role of the drum is to make the water circulate
washing product
between the laundry fibres in order to enable dirt to be detached and carried away.

THE WATER
4 - THE WATER
The water covers, in the nature, a cycle due to its continuous evaporation under the action of the sun
heat; this vapour is condensed into fine droplets to produce clouds, which are transformed into rain
when they meet a cold air draft.
It is possible to assert practically that this is from the moment where the rain starts falling that it begins
to lose its purity. Actually, during its fall, the rain meets in the atmosphere a certain number of
impurities of variable nature, among which carbon gas with which it is combined to make up very
slightly acid soft water.
This water, when it arrives on earth, flows by streaming and infiltrates the cracks to reach the
groundwater tables and artesian tables that feed sources and wells. In both cases, this water dissolves
and carries with it a part of the mineral salts it meets (limestone, magnesium, etc.); this is this last
process, which causes its mineralisation. The more the water is mineralised, the
The water hardness is expressed in degrees TH.

From 0° to 5° TH very soft water
From 5° to 15° TH soft water
From 15° to 30° TH half-hard water
From 30° to 45° TH hard water
More than 45° TH very soft water
The value can be expressed in TH or DH (German) : 1° DH = 1.78° TH
4.1. - The noxious effects of limestone
Any water contains traces of minerals, mainly limestone, magnesium and iron originating from the
ground. The higher the content is, the harder the water is. These minerals reinforce the dirt catch to
fabric fibres, and the eliminated one tends to be fastened again to them. Limestone reduces the
efficiency of the washing product, makes the laundry rough, makes whites turn grey, fades colours and
accelerates the laundry wear.
4.2. - The effects of too soft a water
Too soft a water also reduces the washing efficiency (reduction in mechanical action), causes foam
overflows, leaks and accelerates the appliance ageing (the water is more aggressive).

Standard powder

Tabs
Liquid
Dedicated washing
products
Contrary to many received ideas, all the washing products are not identical. They contain specific
ingredients. Several types of product may not be used for washing :
The powders
¾
Efficient on most dirt and at any temperatures. They contain whitening agents and optical brightness.
So-called "standard" powders and concentrated powders exist.
The tabs
¾
The dosage easiness explains certainly the development of their market share (15% two years after
their launch). In fact, they are compacted powder. Manufacturers recommend from one to three tabs
according to the water hardness and the laundry dirt level. They are to be placed either directly before
placing the laundry, or in the supplied small net, in the middle of the laundry. They are not to be placed
in the product compartments. The dissolution time may vary from 10 seconds to more than 10 minutes.
The liquids
¾
They ensure perfect dissolving from the lowest temperatures. Liquid washing products make the stain
pre-treatment easier and they never contain whitening agents.
The liquid washing product in dose
¾
This is a dose of concentrated liquid washing product, which does not dissolve entirely during the
wash. It is to be placed in the bottom of the drum before the laundry. It shall not be placed in the
product compartments.
The dedicated products
¾
Specifically formulated washing products exist to take care of delicate fibres and delicate coloureds.
Free of whitening agent, these washing products contain fibre and colour protecting agents. These
products exist as "standard" or concentrated powders or liquids.
The softeners
¾
These are comfort additives. Such products have no effect on the wash performance. Using softener
on the last rinse is used to obtain soft and agreeable laundry, and prevents the generation of static
electricity.
The chlorine (bleach)

Chlorinated product may not be used for white or colourfast cotton articles.

the front and the back.
7.4. - Electrical connection
Use a plug with a ground, easy to reach and protected by a 16A fuse. Never use an extension cord or
an adapter. In a bathroom, the machine must be 60cm away from a water arrival. The installation must
respect the standards of the country.
7.5. - Water supply
Machines with two valves can be supplied with hot water (maximum 60°C), which reduces the heating
duration and the cycle duration ( about 15 minutes). This option is interesting if the water is cheap.

This option called is not fitted to all the models.
8.3. - The water recirculation
THE RANGE
A recirculation pump equips "all electronic" programming, which improves the laundry moistening,
decreases (or even eliminates) detergent losses and increases washing performances. The water is
pumped, filtered (only one tank filter for draining and recirculation) and sprayed onto laundry through
the tank and drum (perforated around its shaft). The recirculation is used at the beginning of cycle
(during the cold mixing) to increase the laundry impregnation by the detergent bath, and then after
heating, to improve washing performances, and lastly during rinses, to decrease the water
consumption.
8.4. - Filter cleaning
For efficient recirculation, the tank filter of "all electronic" machines shall be cleaned every 100 washes.
The electronics signals the moment where this operation shall be performed :
•
2 spin LEDs slowly flash on L0 :
•

of this contact, the board knows the
distribution cam position.
It can thus cut the power supply to
micro-motor when the distributor is

of :
•
An upper half-tank integrated the

•
A lower half-tank, of basin type, to
which the compression chamber,
draining pump, filter, vent, overflow
and immersion heater are secured.
2 inlets, under the level of the drum shaft
leave the water flow from the recirculation
pump.
The sealing between the two half-tanks is
obtained by a seal in groove, 55X2935,
which is to be installed as per the
opposite drawing.
The drum receives the laundry to be
washed.
The stainless steel surface is drilled with
many small holes for the water to be able
to flow in and out freely.
Two crossbars, 55X2983, support the
bearings that hold the drum in the tank
and allow its rotation.
A ‘V-ring’ gasket installed on the drum
shaft ensures the sealing between drum
shaft and spacer ring.

Perforations around the shaft enable the
water sent by the recirculation pump to
reach the heart of the laundry.
Only on "all electronic" machines, it is
used to improve the laundry moistening,
the mechanical action, rinses, and to
decrease detergent losses while allowing
decreasing the water consumption (42

The draining pump is fed by programmer contact 4-4A from the end
of the second rinse (step no. 26). If the "1/2 load" button is pressed, then the pump
supply circuit is cut off. Therefore, the level remained high does not allow a new filling
for rinse no. 3. This is then performed with the previous bath.
This option suppresses then a rinse (the no.3). Actually, choosing this option is
motivated by a less significant and little dirty load to be washed with an appropriate
quantity of washing product, and therefore a less significant need in water during the
rinse.
On the steps 35 and 55 of cotton/synthetic and delicate cycles, the main power contact
2-2A is open. The electric supply of the timer is still possible with the contact 23-23A
(contact of the speedy cam of the timer closed 14.6s by revolution) provided that the
option button is not pushed.

8.7.2. - P2 ASIC operating principle
The main current supplies to the board card :
•
A power supply for the motor command
•
A supply to get continuous current used by the electronic components.
•
An electric base (0V) for the command of the triac which supplies the motor and the time base.
The timer supplies to the board card
•
The code of the task to carry out (wash rates, type of spin), thanks to 2 contacts of the timer 6 and 4.
The tachometer supplies to the board card :
•
Information concerning the speed of the motor on 1.2V~/1000rpm motor form.
The « stop position » sensor indicates to the board card :
•
The position of the small doors thanks to a contact fixed on the tank and commanded by a
magnet fixed onto a disc located at the extremity of the drum axle.
The P2 ASIC board card insures the following functions :
•
Supplying current for the motor by a triac and regulation of the speed of the drum with the help of
information supplied by the tachometer.
•
Motor rotation reversed by 2 relays which reverse the way of current only in the stator. The relay
reverses only when there is no tachometer signal and when the triac is not commanded.
•
Positioning of the small door with the command of the motor and reading of the « stop position »
sensor.
•
Control of the safety « short circuit triac »
•
Reading of the A and B timer codes, transmitted by the timer (depending on the position).
This indicates the rates and type of spin to use.

This model, generated with a timer code (4-4A and 6-6A closed), is used for the final spin of every
program and for the intermediate spin of the delicate program. The step of the timer (3,6 or 12 min)
defines the time and the spinning speed. However, these times can be shortening if unbalances are
detected or if there is high deceleration of the drum (in case of overloading). The speed potentiometer
determinates the maximum speed if the spin model is reached. Any speed adjustment is immediately
taken into account.

Failure of the motor or connection cut off
•
speed increases is cut off after 2.4 seconds. A second testing, is carried out. If the failure is going
on, only a disconnection of the machine can initialise the memory of the failure.
Triac in short circuit :
•
as the board card detects a very high speed motor, it stops the supplying
of the motor. As soon as the speed is equal to 0, the relay is commuted again without
commanding the triac. If the tachometer signals that the motor is in rotation, the triac is therefore
considered in short circuit and the relay is cut off. An On/Off of the machine must be effected in
order to cancel the memory of the failure.
Cut of the speed potentiometer or high level during spinning :

Unbalance
•
: the board card analyses the tachometer signal when 80 and 110rpm are reached, in
order to get the smallest unbalance and insure a safety spin. The number of attempts are limited
by the spinning time and directed by the timer (15 min with cotton program).

On this type of programming, the draining pump and the electrovalve are wired in series.
Moreover, the pressure switch is calibrated to have lower water height in tank and thus provide reduced consumption (water and
energy). To obtain a mark A in wash quality, a chronometric filling complement of 30 or 45 seconds (contact 4B-3B) is performed on
rinses no.1, 2 and 4 of cotton / synthetics programmes, and also on the filling and and the 3 rinses of delicates programme.

On start-up of all the first cycles, the machine proposes at once the colour programme at 40°C with
maximum spin speed (up to 1300 rpm) and for a duration of 1H58.
It is possible to modify this programme configuration. If the user often makes the same type of
selection, then the machine will take its preferences into account and will then propose it the most used
programme from the last 5 performed ones.
Calculation of achieved savings

8.8.3. - Operating principle of the "Full electronic" programming
•
The 230V~ mains provides the module with a power supply to create a DC voltage used by the
electronics (components and relays)
•
The board manages the run of programmes according to the consumer's choice and to the
information read by its sensors (NTC, pressure switch, tachometer, posistop, RS30 contact, door
safety contact). It also informs the consumer on the cycle run, signals the presence of a possible
fault, and manages several safety devices.
•
The motor power supply is managed by the board that pilots a triac and regulates the drum speed
(from 35 rpm to 1300 rpm), using the information given by the tachometer (as a 1.2 V~ voltage /
1000 motor revolutions)
•
Two relays reverse the current direction in the stator reverse the motor direction.
They change when the tachometer signal is zero and the triac is not piloted.
•
A relay shuts down a stator for changeover to motor overspeed (from 1020 to 1300 rpm).
•
A contact (secured to the tank) controlled by a magnet (assembled to a disk at drum shaft end) is
used to control the up position of doors.
•
Motor, pumps, latch, electrovalve and RS30 are fed by triacs. The immersion heater is fed by a
relay.

8.8.5. - The load recognition (automatic weighing)

load levels and to launch an appropriate wash recipe.

Mixing + water complement up to L1 and measurement of Q2
Mixing + water complement to maintain L1 and calculation of Qt
These measurements of filling times require very precise electrovalve and pressure switch.
8.8.6. - Energy Labelling EL60° (cotton 60°C without option)
As soon as the consumer selects a cotton cycle, without option, at 60°C with maximum spin speed,
and if during the weighing the board determines that the load is 5 kg, then the electronics executes
automatically an optimised cycle corresponding to the specific features of the standard, as regards the
energy label.
8.8.7. - The unbalance
At the start of spin profiles, the board analyses the tachometer information and looks for a minimum
unbalance (speed as stable as possible) on the dwell at 80 rpm. Then, if it obtains it, a new search,
finer, is performed on the dwell at 110 rpm, before continuing the spin without any risk. The machine
has a time sufficient (variable according to the spin profile) to make several attempts before finding the
minimum unbalance allowing its speed rise. In the case where a significant unbalance could not be
eliminated, a spin with limited speed (different according to the chosen programme and the measured
unbalance) would be nevertheless performed (450 rpm in the worst case)

8.8.9. - Foam detection
The foam detection is validated if high level of the pressure switch is read during speed rises of
intermediate spins. If there is foam detection, then the motor is no longer fed and the spin is cancelled.
The phase intended for spin ends at 5/10 rate at 50 rpm. The "Rinse +" is then performed automatically
after the second rinse, and spin profiles following the foam detection are different (shorter speed
dwells, and addition of a dynamic draining).
