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.

5. Test Mode
5.1. Autotest
5.1.1. Autotest Steps
1. Open SI by pressing SW4 for 5 seconds.
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:
Drain pump is activated.
EPS frequency is checked.
Step2:
Motor ramps to max spin.
Prewash & Wash valves are activated in order.
Step3:
Motor ramps down to stop.
Prewash & Wash valves are activated simultaneously.
Step4:
Motor turns clockwise (low speed).
Step5:
Motor turns counterclockwise (low speed).
Step6:
Twinjet is activated.
Step7:
Prewash & Wash valves are activated simultaneously.
Step8:
Washer heater is activated. Washer NTC values are
checked in this step.
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.
1. 2. Press button below “AU” indication which stands
for Autotest.
2.
3. When autotest is finished, END screen is
visualized.
5.2 Program Parameters
When the SW2 ‘’memory’’ button is pressed as long as 10
seconds at any moment, The parameters of the program
occus on the display:

6. Service Mode
6.1. Service Autotest
5.1.1. Service Autotest Steps
1. Open SI by pressing SW4 for 5 seconds.
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.
In case of no failure at the end of heating step, “Please
change selector” will be displayed. 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.
*If user changes the selector position, machine will do
what is defined for the new selected position.
Step2:
Drain pump is activated; in case of a pump failure it pops
up E03 error.
At the end of pump activation, “Please
change selector” will be displayed. You can turn program
knob to 3rd position to continue with step3.
Step3:
Rapid 12’*(15’ for non-TJ models) program algorithms is
run testing all washing components, the only difference is
error codes are displayed on SW3 which normally are not
displayed to end user.
If case of no error service autotest ends and "End" is
displayed.
3. 2. Press button below “SAU” indication which stands
for Service Autotest.
3. When autotest is finished, END screen is
visualized.
