Angelina,
I’ve given this some thought, in fact I woke up thinking about it. Though I’ve never removed a wringer from the body of a washer, I’ve certainly used aand owned a Maytag wringer washer in the past, and I’m familar with how they work in principle.
Since you now have a owners manual, if it gives you the instructions on how to remove the wringer assembly from the body of the washer try removing it. Now plug the machine in and look down the hole where the wringer fits into the machine. I would imagine that there must be a shaft with gear teeth that the wringer head fits into. Look and see if this shaft is turning when the power is on. If it is, then like Stan said, the wringer head was probably not seated properly into this hole so that the gears from the turning shaft can properly engage with the drive gear for the wringer head.
Read the instructions carefully to see if there is an explanation on how to properly reseat the wringer head assembly so that the gears mesh between the drive shaft and the wringer head drive gear. I hope this all makes sense. I can visualize it in my minds eye. This may be the solution for your wringer not turning. I hope that this helps you. If this was my machine, this is what I would try doing in my own tenacious, Rube Goldberg, DYI sort of way,
These are really wonderful machines, and really pretty simple. I can’t imagine that if it has been barely used that anything major could be wrong with the wringer. It may have just been somehow disengaged with the drive shaft gear.
Good luck, and I hope you can get it up and running. You will love using it.
