Washer will fill but won't spin or agitate

Our wash machine filled. But stopped after that. When i tell it to fill it does but after that it just hums on some controls and wont even make a sound on the spin settings

If the machine will drain it sounds like a coupling problem, with the hum being the motor turning but not doing anything.

This video will show you how to check it. Don’t take off the pump, just tie it off to the left.
