Question about Brother LB6770 PRW Computerized Sewing Machine
I keep getting an error code, "check and retread the upper thread" but the upper thread is threaded. The manual says to stop and rethread every time but I can't do that for every inch I stitch! Ever heard of this before?

Hi....I also kept getting the check and rethread upper thread message, I\'d sew about 15 stitches and it\'d stop. Here\'s what I did. On the left of the machine, in the back there is a screw....loosen that screw, take cover off, then lift straigt up and out on the cover that has the 3 on it in your threading seqence. Next, I started inspecting and cleaning the thread route from top to bottom. Lo and behold....I get to the place where you come down the front of the machine and turn to go back up and I spot a little slit in the plastic piece so, when I was threading the machine I guess I was pulling it to far to the left causing it to wear a little slit in that piece....so, I finished cutting it off with a utility knife, used an emery board to smooth it down, put the covers back on and it works GREAT!!!! Who would\'ve ever that it\'d be so easy and save me a bunch of money!!! I sure hope this helps someone.
