Brother xl-3500 sewing machine will not wind a bobbin

SOURCE: Brother Sewing Machine model:CS8150 bobbin thread problems

The top of the machine is not threaded correctly. First raise the presserfot then rethread the machine. Bottom looping is usually caused by a lack of top tension. There could allso be a bur on the hook.

Hi again,

Well we finally downloaded a service manual that cost a few bucks, then finished getting the machine apart, then found a small rubber O-ring that had obviously gotten hot when spinning after the tangling of the thread on the bobbin stem. You could see where the heat had melted tiny teeth marks in the ring and it was stretched out of shape. It and yours too will need to be replaced.

If you or someone you know is mechanically inclined, you will need to take five screws out of the back including a hard to find one under the foot raising lever (lower the foot), then one form the front that is under the thread cartridge, and you will have to remove the bobbin winding plate cover which is held by one small screw, and then remove a small screw from the support bar.

Good luck!

the rubber ring on the bobbin winder has probably gone bad which would mean replacing it but you can buy a portable bobbin winder called a sidewinder for around 20.00
