Does it work ok if you play by pressing the Spin button and don't use the pull handle? If so then you can check the parts around the pull handle mechanism. I think there are a couple of microswitches in the pull handle mechanism and a locking solenoid, all are inside the machine on the right side wall where the pull handle axle comes inside the machine. One of those parts might be acting up or loose. Look up in there with a bright light and examine things, have someone slowly pull the handle as you are looking, maybe see what is happening.
