If the stitching on top is rough or frays, one of these issues may be the root of the problem.
Incorrect bobbin tension
The bobbin needs to be tensioned correctly for stitching to come out correctly.
The bobbin may be bent or damaged and need replacement.
Dull or bent needle
If the needle is bent, broken, or dull, the machine will stitch incorrectly. You may need to replace the needle.
Fabric gets ruffled when sewing
If your fabric is getting ruffled or bunched while feeding through the machine, one of these issues may be the cause.
Damaged presser foot lowering mechanism
The lowering mechanism provides compression to the presser foot. If your presser foot is not lowering completely and evenly, you may need to replace the presser foot lowering mechanism.
Damaged presser foot
The presser foot holds the fabric in place, and if it's damaged the fabric may not smoothly pass through the machine. You may need to replace the presser foot.
Sewing machine won't turn on

Foot pedal/power cord are unplugged
If the machine won't turn on, check to see if the foot pedal is plugged into the wall and the machine.
