Frigidairre Washer - Cycling, no agitate or spin

Our washing machine does not agitate,nor does it spin. It cycles through the timer correctly. I first noticed a loud buzzing/humming during what should be the spin cycle. I started the cycle over to see if if agitates. It does not.

Does the belt have anything to do with the agitation? If not, what could affect both agitate and spin?

Any help you can provide is greatly appreciated!!

The belt is what drive the agitation & spin.
