Washer won't spin

The washer DOES agitate and DOES drain, however, it DOES NOT SPIN to remove the excess water from clothes. I did turn the agitator counterclockwise and this did initiate the spin cycle and it did remove the water from the clothes. It it NOT making any loud or weird noises. What needs to be repaired? Thank you.

Can you hear the motor running during the spin cycle when the tub does not spin?
