Kenmore front loader not spinning

Kenmore front loader washing machine has stopped spinning.  I have cleaned out the coin catch, which was full and was able to spin the little fan inside.  After that the machine would spin, empty, on a low-med speed.  I put clothes in, and it would not spin again.  Then, I put vinegar down the tube that connects to the pressure sensor.  It would spin, on high, this time for a few minutes, and then stopped again.  I can not get it to spin at all now.  It does drain just fine though.  Can you please help?
