1. Safety Precautions
Important:
This service information is designed for experienced repair technicians only and is not designed
for use by the general public. It does not contain warnings or cautions to advise non-technical
individuals of potential dangers in attempting to service a product. Products powered by
electricity should be serviced or repaired only by experienced professional technicians. Any
attempt to service or repair the product or products dealt with in this service information by
anyone else could result in serious injury or death.
Warning:
Before any disassembly/repair operation make sure appliance is unlplugged water tap is closed
and heating elements are cooled down. There is electrical shock, burning and flood risk.
Warning:
Please replace whole cable group even in case there is any minor failure with cables / terminals /
sockets. Never try to repair nor to solder cable group. It may cause smoke, ignition and there is
major risk of electrical shock.
Important:
Always use insulator gloves to prevent injury by metal edges or to prevent electrical shock during
electrical tests.
Work with uniforms having long sleeves to protect your arms from metal edges.
Always use original spare parts. You may harm appliance, end user, environment or yourself
using untested and unapproved 3rd party spare parts.
Use right tools to prevent any wear or damage to components during assembly/disassembly.

2. Specifications
Here you will find descriptions of generic specifications for the range specified for this service manual. Please refer to
product fiche and user manual for detailed technical specifications.
*Twinjet System:
Twinjet system is designed to obtain a better washing performance by directly injecting water
with detergent using a recirculation system and two nozzles connected to it. With twinjet
system, water consumption is decreased by 30%, energy consumption is decreased by 10% and
washing time is decreased by 15%
Twinjet system is valid for all programs except spin and drain mode. The system dos not function
during Water inlet, heating, spinning, drain phases.
Even with a large load of 8 kg. the washing machine will have the minimum energy consumption
by the help of Twinjet system.
Washing machines with Twinjet system are very environment-friendly by having maximum
washing performance with minimum water consumption.
Eco-Logic System:
Half load detection system, thus using less water and power accordingly. This system is available
for cotton programs only.
Foam Protection System:
Foam Protection System is a safety algorithm that interrupts normal program flow and reduces
foam level by taking water and draining. This algorithm protects machine and environment
avoiding over foaming inside tub in case any customer misuse such as detergent overdose or use
of foamy cleaning agents.
Overflow Protection System:
Overflow protection is another safety algorithm in case of a flood risk. If there is more water in
tub than expected by algorithm, it will start to the drain routine giving E04 failure code. For
example this may happen in case of a valve failure and the machine constantly takes water. This
algorithm will keep drain routine, keeps water leveled and protects environment and machine
avoiding any flood risk.
Unbalanced Load Detection and Control System:
Unbalance Control System is another safety algorithm that protects the machine and
environment avoiding machine movement due to vibration during spinning profile. The
algorithm tries to balance load by a special balancing agitation, postponing spin profile till it is
balanced. This avoids spinning while load is unbalanced and prevents any possible physical harm
both to the appliance and to surroundings.

4. Test Mode
4.1. Autotest
4.1.1. Autotest Steps
1. Press and hold SW5.
Autotest follows a predefined flowchart in order. Unlike
service autotest, autotest automatically skips to next step
upon completing one. The steps of the test are as follows:
Step1:
The drain pump is checked.
Step2:
Motor ramps to max spin speed while valves are activated
in order.
Step3:
Motor stops, both valves are activated simultaneously.
Step4:
The motor turns to right. Also, dryer valve is activated.
Step5:
The motor turns to left.
Step6:
Both valves are activated. (Water intake for heating)
Step7:
Washer NTC is checked.
Step8:
Washer Heater is checked.
Step9:
Dryer resistance I and I&II are checked.
Step10:
Dryer NTC is checked for 2sec.
Step11:
Fan is checked.
In case of no failure test ends after this step and “End” is
displayed. In case of an error detection EXX and error
definition will pop up on display. (where XX is the error
number 1 to 10 )
Please see following autotest chart for details.
2. While pressing SW5, turn PR to 1st position
(Cotton). Wait 3 seconds and release SW5. During
test “AU” is visualized on display.
3. When autotest is finished, END screen is
visualized.

EPS measurement: It checks the EPS and if it OK, it continues the autotest; if it is NOK then cancel the Autotest and go to the selection mode. Also if any frequency can not be detected, then it means there is problem with connecion
or EPS, so it gives E10 which is EPS error and cancels the autotest & goes to the selection mode.
Dryer Ntc detection : Software will detect NTC's resistance value and will check if the temperature is between 0°C < Tdetected < 50°C. If it is inside the range, heating step will be done.
Washer Ntc detection : Software will detect NTC's resistance value and will check if the temperature is between 5°C < Tdetected < 40°C. If it is inside the range, heating step will be done.
If temperature value is outside the range, then it means NTC is detecting the temperature in a wrong way and heating step will be skipped. Additionally if NTC connector disconnected it should shows NTC failure code(E05) on display.

5. Service Mode
5.1. Service Autotest
5.1.1. Service Autotest Steps
1. Press and hold SW4.
If you turn knob position to other program between 1st to
3rd it will skip current test and start the selected one. It is
recommended not to skip any steps for a detailed
checkup. Unlike autotest, service autotest starts next test
step manually by rotating program selection knob.
Step1:
There will be a certain amount of water intake and then washer heater is
activated for 8 minutes. Washer NTC values are checked in this period.
In case of a washer heater/NTC failure, it pops up E05 error displaying
“E05” on SW3.
At the end of heating, "SAU" visualization should make slow blink to
indicate that the step is over. You can turn program knob to 2nd position
to continue with step2.
*During this step if EPS detects high water level, overflow algorithm is
applied and E04 is released.
Step2:
Drain pump is activated; in case of a pump failure it pops up E03 error.
At the end of pump activation, "SAU" visualization should make slow
blink to indicate that the step is over. You can turn program knob to 3rd
position to continue with step3.
Step3:
Dryer Heater I and fan is activated. After 3 mins if there will be no
temperature change (ΔT< 10°C), it will release E14 failure.
If temperature increases accordingly (ΔT > 10°C), "SAU" visualization
should make slow blink to indicate that the step is over. You can turn
program knob to 4th position to continue with step4.
Step4:
Dryer Heater II and fan is activated. After 3 mins if there will be no
temperature change (ΔT< 10°C), it will release E14 failure.
If temperature increases accordingly (ΔT > 10°C), "SAU" visualization
should make slow blink to indicate that the step is over. You can turn
program knob to 5th position to continue with step5.
Step5:
Rapid 15’program algorithms is run to test all washing components, the
only difference is error codes are displayed which normally are not
displayed to end user.
If no error found in test program ”SAU" visualization should make slow
blink to indicate that the step is over. You can turn program knob to 6th
position to continue with step6.
Step6:
A 5 mins drying program is run to test all drying components.
If case of no error service autotest ends and "End" is displayed.
*If user changes the selector position, machine will do what is defined
for the new selected position.
2. While pressing SW4, turn PR to 1st position
(Cotton). Wait 3 seconds and release SW4. Step 1 of
service autotest will start. During test “SAU” is
visualized on display. Please see details about steps
in right column.
3. When autotest is finished, END screen is
visualized.
