Hi, i have this washing machine and i'm having issues with the motor that moves the water inject nozzle. It won't point to the right chamber. For example, it points to the fabric softener chamber when its supposed to point to the main wash chamber. The motor just turns and stops at random positions. I've checked the wiring and connectors and they are ok.
How does the mainboard know when the nozzle is pointing at the right chamber? What else should i check?

Hi!
The actuator have a resistor net, and the resitance say the controll unit what the position. If the contacts are bad the control unit not stop the correct position. Disassembly the actuator and clean the contacs solve the problem.

Hi again, I finally repaired it. It turns out that the motor is not original. Someone replaced it before i got this machine. The motor is supposed to turn clockwise only and the motor installed turned both ways. That's what caused the synchronize issue. So i replaced it and problem solved!

Hey! Thanks for replying. So i took the motor apart and cleaned everything but it keeps doing the same thing.
Here is what i've checked:
When you turn on the washer or start a cycle, the cam moves to the prewash position. If you select prewash, the washer starts filling in that position. If prewash is not selected, the machine fills in the prewash chamber for a few seconds, and then should move to the main wash chamber.
Now, two things can happen when it's supposed to move to the main wash chamber: if the cam turns clockwise, it reaches the main wash chamber properly. If it turns anti-clockwise, it stops in a random position. In both cases the motor is energyzed 8 seconds.
This made me think that maybe the motor is controlled by time, and not by a resistance, but it turns both ways so it can't be possible.
If i remove the main gear (wich makes contact with the resistor net) the motor keeps turning. After 10 minutes the display shows "ERROR 10" (faulty motorized selector)
The motor doesn't have any resistors, just a big outer plate and a tiny inner contact, wich makes the motor stop in the prewash chamber when the main gear makes contact with it
Any ideas? Thanks again!
