Skips final spin on certain cycles

When putting washer in the W/W cycle it does not complete a final spin . The clothes still dripping wet. When placed in the second rinse cycle spins strong. I checked wiring connectors on motor all seem to be in good working order. Washer is level, clothes are balanced. I’m guessing the timer switch?? What do you think?

Have you watched it closely during a final spin? More specific description might help.

What means “W/W”?
