Not agitating.

Hector
The two most common problems on a no spin for this specific model are :
1) Agitator coupling that strips out.
2) The mode shifter.

If you can find the technician sheet in the machine normally by the control panel. It will instruct you how to determine by blinking lights near the motor what part is defective. Every machine is different but I did provide you with a video of each repair and a parts breakdown link. Thanks Matt Ace technician
