I have had my Janome 6500 for over 5 years now and have never had a problem with it at all. I do know that my dealer would immediately replace the machine if it was under warranty and I had a problem like yours. I lost my first Janome in a house fire and the adjuster told us that even though the fire was only in 1 part of the house, all our electronics were shot. I hope your dealer is as good as mine and that you walk out of there tomorrow with a brand new machine in your hands.
