I have a homefill II that will not turn the pulley. The motor works fine and turns the belt, but no pulley movement. I found disassembly/assembly instructions online. I have removed the control panel and motor/pulley assembly. The pulley was tight to hand turn at first, but was able to turn the pulley enough so it now seems to spin freely. The belt is in great condition, so I don't think that is/was the problem. Anyone with the same or similar problem that has a diagnosis before I reassemble?
