Unplug the machine for about 15-20 min. It should unlock it's self and it should reset. If this doesn't work, let me know and I will look up the service manual and get back to you asap.
Check to make sure you have it set to spin "more dry" sometimes mine gets set to a lighter spin. After checking to make sure all the settings are right, if it still does it you will need to call for service, it could be that the bearings are going out or that there is something wrong with the direct drive system. It could also be something wrong with the timer.
Let me know if this helps!!
