Sounds like when you moved it, either you have disturbed the control panel or door lock. Check the ebayers feedback, have they sold before, if they have a good rating on selling, did they invite you in there home and not a shop, met you somewhere or even delivered, if they have had good feedback on selling and invited you in there home my bet would be they are genuine sellers. If they were dodgy or con artists I dont think they would have given you home address. Through past experience with these machines is they are ok to move from room to room, but once in transit somehow they do lose their lock connection. It is still machine I would never do without, they are worth the minor repair.
