7. Spinning When Washing
W/M is spinning
in washing step.
After spinning
attempt, does it pass
to 'pause' mode?
No
Disconnect KN9 from main PCB and
measure the motor coil resistance. The
expected values should be like below.
KN9.3 – KN9.2 = 0.8
KN9.3 – KN9.1 = 0.8
KN9.4 – KN9.5 = 2.8
KN9.6 – KN9.7 = 54 (Tacho)
Is the tacho coil
resistance Ok?
Yes
Check to tacho magnet:
Connect a voltmeter between KN9.5 and
KN9.7. Open the W/M front door, rotate
the drum with hand then measure that AC
voltage increases and decreases. Drum
does not rotate voltage should be 0V.
Does the desired
voltage value can be
measured?
No
Change the tacho.
Tacho failure. (8 trials
Yes
with 120 seconds time
intervals).
No
Change the tacho or/and motor.
Yes
Change the main
PCB.
18
If 3 spinning attempts are
occurred by 30 seconds
time intervals, this shows
motor triac short circuit
failure.
