2. Washing Machine Doesn't Work (After Filling Step Is
W/M does not work (after filling
step is performed)
Be sure that, the filling step is
exactly completed and the valve is
closed.
Disconnect the KN9 socket from
main PCB. Measure the Motor
coil. The expected values should
be like below.
KN9.3 – KN9.2 = 0.8 Ohm
KN9.3 – KN9.1 = 0.8 Ohm
KN9.4 – KN9.5 = 2.8 Ohm
KN9.6 – KN9.7 = 54 Ohm
Are the measured
values (Motor coil
resistance) Ok?
Yes
Check the tacho magnet:
Connect a voltmeter between KN9.6 and KN9.7.
Open the W/M front door, rotate the drum with your
hand then measures that AC voltage increases or
decreases according to movement. If the drum
does not rotate, voltage should be 0V AC. Do you
read increase or decrease value from multimeter?
Yes
Be sure that, KN9 socket pi8ns
must contact to main PCB
properly. It means that KN9 pins
are not been bended. Are any of
them bended?
No
Check if draining is
performed, if so, check
if the aqua stop switch
is on?
Performed)
Check the motor connection. If there
No
is no problem at motor connections,
change the motor.
Yes
No
Change the main
PCB.
NOTE:
After the filling step is completed. If the motor
does not run or the tacho does not been
generated a voltage, which is proportional with
the motor revolution (tacho defect). In this
condition, main Power Board tries 8 times (the
duration between two trial time is 120 sec) to run
the motor. If the problem does not solved, motor
will not be energised again, pump motor will run
and machine will turn to program selection
mode.
No
Change the tacho of
motor.
Repair the socket
pins.
