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.

Please contact WMCS department for tacho and stator resistance values of motor component used
in your appliance. Do not forget to provide serial number information of appliance in your inquiry.
Page 28
8.8. Door Lock*
Door lock is activated at the beginning of the
program in order to prevent the door from
opening. Locking is generated by supplying
power to PTC-bimetal, after max 6sec (220V),
the bimetal will be warm and ready to close the
contacts. Thus the first impulse to the solenoid
will allow the contact to close and consequently
the slider will be locked by the pin of the
sliderlock. The second impulse causes no
electrical and mechanical modifications. It can
be unlocked by the third impulse; the contact is
opened even if the PTC-bimetal remains
energized.
Emergency Opening System (PTC-Bimetal) In
Case of Lack of Electric Energy
• In case of lack of electric energy during a
washing cycle, the PTC-bimetal assembly will
cool down and after minimum 60 sec
(considering previous power supply of 30 sec
min and T=20 °C) the door will be unlocked and
thus can be opened.
• In case the door is closed when current comes
back, the PTC-bimetal assembly will heat again,
the slider lock will lock, the contact will close and
the program will continue from where it
stopped.
