The upper thread may be breaking because the thread path is obstructed, the machine isn't threaded correctly, or the upper tension is too tight. Check if the thread is caught on the thread spool or behind the spool pin. If not, remove the upper thread completely, raise the presser foot lifter, and rethread the machine. You may also need to reduce the upper thread tension.
Why is my Singer HD6620C skipping stitches?
Skipping stitches can occur if the needle is inserted incorrectly, you're using the wrong needle for the fabric, or the needle is bent, dull, or damaged. Check that the flat side of the needle top is toward the back of the machine and the needle is up as far as it can go. Use the correct needle style and size for your fabric. Discard the needle and insert a new needle if it is bent, dull, or damaged.
Why is the bobbin thread breaking on my Singer Sewing Machine?
The bobbin thread may be breaking for a few reasons: the bobbin might be threaded incorrectly, wound too full or unevenly, there might be dirt or lint in the bobbin holder, or you might be using the wrong bobbins. Check that the bobbin is placed correctly in the bobbin holder. Ensure the bobbin thread was correctly placed into the bobbin winding tension disc during the bobbin winding process. Clean the bobbin holder. Use bobbins that are the same style as those that come with the machine (SINGER® Class 15 transparent bobbins) – don’t substitute.
Why is my Singer HD6620C Sewing Machine not feeding fabric?
If your sewing machine isn't feeding fabric, it could be because the presser foot lifter hasn't been lowered onto the fabric after threading, the feed teeth need to be raised and re-engaged, or the stitch length is set at zero. Lower the presser foot lifter before starting to sew. The feed teeth need to be raised and re-engaged by turning the handwheel one full revolution. Increase the stitch length setting.
Why is thread bunching at the beginning of my seam on my Singer HD6620C Sewing Machine?
Thread bunching at the beginning can be due to the top and bobbin threads not being properly placed, starting to sew with no fabric under the presser foot, or needing a stabilizer. Ensure that both the top thread and the bobbin thread are under the presser foot and toward the back. Place fabric under the foot, making sure that the needle comes down into the fabric. Place a stabilizer underneath the fabric.
How to fix thread loops on the underside of fabric with a Singer Sewing Machine?
If you notice thread loops on the underside of your fabric, it's likely due to incorrect threading. To resolve this, rethread the Singer Sewing Machine, remembering to raise the presser foot lifter before you start.
What to do if my Singer Sewing Machine will not run?
If your machine won't run, the bobbin winding spindle might be engaged, the power cord and/or foot control might not be plugged in correctly, or you might be using the wrong bobbins. Disengage the bobbin winding spindle by pushing it to the left. Make sure the power cord and foot control are correctly seated in the machine and power supply. Use bobbins that are the same style as those that came with the machine (SINGER® Class 15 transparent bobbins) – don’t substitute.
Why am I experiencing bobbin winding difficulties with my Singer Sewing Machine?
Bobbin winding difficulties can arise if the bobbin thread is loosely wound, the bobbin winding spindle isn't fully engaged, or the bobbin is winding sloppily. Rewind the bobbin, making sure that the thread is placed snuggly in the bobbin winding tension disc. Check that the bobbin winding spindle has been fully engaged before starting to wind. Before starting to wind, hold the thread tail (coming out of the bobbin) securely, allow the bobbin to partially fill, then stop to trim the thread tail close to the bobbin.
Why is my Singer HD6620C Sewing Machine making a loud noise when sewing?
A loud noise during sewing can be caused by the thread not being in the take-up lever or an obstructed thread path. Rethread the machine, making sure the take up lever is in its highest position. Check that the thread is not caught on the thread spool or behind the spool cap.
What causes distorted stitches on a Singer Sewing Machine?
Distorted stitches can be caused by pushing or pulling the fabric, an incorrect stitch length setting, or needing a stabilizer for the technique. Avoid manually pushing or pulling the fabric in order to sew. Adjust the stitch length setting. Place a stabilizer underneath the fabric.
