This is an intermittent jam. I am able to go under and pull on the belt and pull it free. A matter of a few minutes in spin until it jams again. During spin the washer noise sounds like pebbles rattling around, I think it is coming from the transmission drive pulley. The noise comes and goes.
This Crosley seems to me very similar to a Maytag Dependable Care. Am I right about that? I am limping along with a Dependable Care service manual, can't find one for Crosley.
