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?
