I got my Bernina 640E in October 2010 for my birthday. When I first went to use it the feed dogs would only move up and down, not forward and back. I read in the book how to remove the face plate and clean that area, so I tried that. Lo and behold, it started working just fine. Since then, I’ve had no need to drop the feed dogs until last night.
Yep, you guessed it…the feed dogs aren’t working again. I did everything I did before and had no luck. So, I’ll have to take it to the store tomorrow and hopefully they can fix it easily. I’m a little frustrated that we spent that much money on a sewing machine that broke so soon.
