FAILURE CODE OBSERVING MODE
Press the first auxiliary function button from the left for 6 seconds. “Run/
Pause/Cancel” led will start blinking and the program followers will start
blinking as an error code for 3 seconds if any failure routine has run.
After 3 seconds, the machine will return to the selection mode.
After entering the failure code observing mode, pressing and holding “Run/
Pause/Cancel” button for a short time will erase the error code from the
memory. After you complete your inspection, if you are not sure that you
have solved the problem and if you are going to change the electronic card
group, do not erase the error code. For else cases, you may erase the error

No
Is the door locked?
(If the door is locked, “Ready”

Yes
Yes
Check if the program selector is in a
position between two programs. If the
blinking of Ready continues even if
you have seen that the selector is not
in between any adjacent positions,
change the control card group.

Check if the card is
assembled correctly to
front panel or not.
Yes
Measure the voltage
between the pins 1 and 3 of
door-lock. Is it 230 V AC?
Yes
Change the door-lock
Yes
Measure the voltage between the
pins 1 and 2 of the filter (brown
and blue cables). Is it 230 V AC?
Yes
No
Check the power cord and fuses.
Change the power cord if you see a
problem there.
Check the cable connections of the On/Off.
If there is no problem at the wiring, change
the On/Off switch.
Important Note:
WM does not work failure means, none
of the functions of the machines can be
done. In this condition, WM will not take
any water, will not do any washing,
draining or spinning.
If “Ready” led (“Door” Led in some models) is not
active, door is not locked and 230 V AC is measured
between L and N terminals of the On/Off switch;
change the electronic card group.
Yes
Do you still observe the
problem?

REMARK
Right after the machine finishes water filling step, if the motor does
non start working or if any motion data is not sensed (Tacho
failures) the electronic card makes 8 take-off trials, waits 120 sec.
between each take-off trial, and if the failure is still detected, the
motor is stopped, and draining starts. Right after draining, the
machine turns to the selection mode.
Make sure the machine completes water
filling step.
Disconnect the J5 and J6 motor
connectors from the main board and
measure the resistance values of motor
windings. Measured vaues must be as
given below:
STATOR IN - COMMUN = 0,5 - 1,5 Ohms
STATOR MP - COMMUN = 0,5 - 1 Ohm
ROTOR1 - ROTOR2 = 0,5 - 1 Ohm
TACHO = 50 - 60 Ohms
Are motor windings OK?
No
First check the motor wiring connections
between the motor and the electronic
card. If there is no problem at the wiring,
change the motor.
Yes
Connect a voltmeter (AC) to J6 (Tacho)
connector on electronic card and rotate
the drum manually. When the drum is
rotating, a voltage value related to the
rotation speed must be seen on the
voltmeter and this walue must be 0V(AC)
when the drum is stopped.
Yes
Make sure that the J5 and J6 connectors
are connected properly to the mainboard.
The terminals of the connector may be
coming out of the plastic body. If there if a
problem at the connector or teminals, try
fixing it.
If the failure still exists, change the electronic
card group.
No
If there is a problem at motor tacho
magnets, change the tacho.

No heating, heater does not initiate.
Check the NTC connections and wiring. Make
sure the connectors are plugged well.
Also make sure that the water level sensor’s
hose is not punctured or congested.
Remark:
In cases of NTC open / short circuit or heater open circuit,
washing machine performs cold washing without activating
the heater.
Measure the NTC resistance from J2 connector’s NTC-5V terminals. Is
this resistance approximately 4700 Ohms at 25ºC temperature? (The
measurement must be a value different than Open or Short circuit)
NOTE: Before doing the measurement, make sure that the scale
setting of your ohmmeter is set correct.
Yes
Make sure that the heater
wiring and connections are
proper and the connectors
are plugged well. Continue
following the flow-chart if the
problem still exists.
No
Measure the NTC after
seperating it from wiring; If
you measure the NTC as
open or short circuit, change
it.
Unplug one of the heaters connectors
and measure the heater resistance. Is
it about 20-30 Ohms?
Yes

Select Pump program and start the program.
Is the pump active? (can be understanded
by touching the filter cover)
No

Is the machine filling water?
No
Can you measure 230 V AC voltage
between pump teminals?

PUMP-NEUTRAL voltage. Is it
230V AC ?

Yes
* Check and Clean the pump filter
* Drain hose level should be between 0,5
and 1 meter from the floor
* Check the drain hose , it ishould not be
banded or broken
If the water temperature in the tub is
higher than 50C, the machine makes
water filling to decrease this
temperature. If the “no draining”
problem still exists after water filling,
check the NTC resistance value.
Pump motor windings are open circuit, change
the pump.
No
Check the wiring and connections
between the electronic card and wires.
Fix if you see any disconnections. If
you don’t see any problem at the wiring
and the connections, change the

WM is spinning at a washing
step.
If the motor triac is short-circuit, motor
will make 2 take-off trials at spinning
step; and pauses 40 sec between these
trials. After these 2 trials the water in the
tub will be discharged by draining.
Un plug the J6 connector and
measure the tacho resistance.
Is it open circuit?
No
Check the wiring and
connections between the
electronic card and J6
connector. Keep following the
flow-chart if the problem still
exists.
Connect a voltmeter (AC) to J6 (Tacho)
connector on electronic card and rotate
the drum manually. When the drum is
rotating, a voltage value related to the
rotation speed must be seen on the
voltmeter and this walue must be 0V(AC)
when the drum is stopped.
