You should search the net for a service manual for these vertical modular washers.
They have a special drive mechanism called a splutch that engages in an out of spin /agitate.
There is a little drive motor (actuator) that rotates and engages the drive basket gear to switch to spin/
The tranny is a sealed sytem consisting of planetary gears for spin and agitate.
The motor is variable speed and is controlled thru the triacs by mainboard.
If the splutch binds then the motor is trying to spin when it thinks it is in drive etc.
The diagnostics are needed as any change or dis-assembly of the motor, cap, drive basket, tranny calls for a recalibration as per the manual.
It monitors motor current to sense amt. clothes and adjust water levels accordingly and spin speeds.
A common prob is the teeth on the drive gear/basket drive strip. The nut comes loose and the drive gear drops.
Also verify the door lock switch contact does not have a high resistance as the neutral is returned thru it to stop the basket when the lid is open.
Also the mainboard has a 5 and 13 VDC supplies that suffer from crappy capacitor syndrome.

Forgot to mention A problem i've seen .
The actuator motor is held in place with one screw in a plastic body. The other motor mounting hole of the motor clicks into a plastic pimple. Yep, rotation forcing and biding cause th e motor to wear down the pimple which cause the motor to move out of position and cause the mechanism to not advanced that extra bit.
