Why does the needle keep breaking on my Bernina Sewing Machine?

  Danielle JacobsonSep 14, 2025
  Needle breakage in a Bernina Sewing Machine can occur if the needle is incorrectly inserted; make sure to insert the needle with the flat side to the back as far up as it will go and tighten the screw. Pulling the fabric can also cause the needle to break, so feed the fabric evenly. If you are pushing thick fabric, use the correct presser foot designed for thick materials, such as jeans. Using knotted thread can also lead to needle breakage, so ensure you are using quality thread.

  If your Bernina sewing machine doesn't start, it could be due to an unfavorable room temperature. Place the machine in a warm room one hour before use. If that doesn't work, the machine may be damaged, and you should contact the specialized BERNINA dealer.

Why does my Bernina Sewing Machine have uneven stitches?
- W
  wgrayAug 26, 2025
  Uneven stitches can occur if the upper thread tension is either too tight or too loose; adjust it accordingly. Other potential causes include a blunt or bent needle (replace it with a new BERNINA quality needle), a poor-quality needle (use a new BERNINA quality needle), poor-quality thread (use quality thread), an incorrect needle/thread combination (match them appropriately), incorrect threading (rethread the machine), pulling the fabric (feed it evenly), or using the incorrect bobbin case (use the supplied bobbin case with triangles).

What to do if my Bernina 770 QE Sewing Machine is skipping stitches?
- Q

  Skipped stitches on your Bernina Sewing Machine may be due to using the incorrect needle; ensure you are using the 130/705H needle system. A blunt or bent needle can also cause this issue, so replace it. Similarly, using a poor-quality needle can lead to skipped stitches, so use a new BERNINA quality needle. Check that the needle is correctly inserted with the flat side to the back, as far up as it will go, and that the screw is tightened. Finally, the incorrect needle point can cause skipped stitches; match the needle point to the texture of the material.

Why is my Bernina 770 QE creating uneven stitches?
- M
  Maria CurtisAug 27, 2025
  Uneven stitch formation in your Bernina sewing machine can occur due to several reasons. The upper thread might be too tight or too loose, so try adjusting the upper thread tension. The needle could be blunt or bent, in which case you should replace it with a new BERNINA quality needle. Using a poor-quality needle or thread can also cause this issue, so ensure you are using quality materials and the correct needle/thread combination. Rethread the machine to ensure it's correctly threaded. Avoid pulling the fabric; instead, feed it evenly. Finally, make sure you are using the bobbin case marked with the triangle.

Why does the upper thread keep breaking on my Bernina 770 QE Sewing Machine?
- N
  Nicholas BrewerSep 13, 2025
  Upper thread breaks on a Bernina Sewing Machine can be caused by an incorrect needle/thread combination, so ensure they are properly matched. If the upper thread is too tight, reduce the tension. Also, check if the machine is incorrectly threaded and rethread it if necessary. Using poor quality thread can also cause breakage, so switch to quality thread. If the stitch plate or hook tip is damaged, contact a specialized BERNINA dealer for repairs. Finally, if the thread is caught in the area of the thread take-up lever, remove the screw on the headframe with the angular Torx wrench, pull the headframe slightly forward, flip it upwards, remove the headframe, remove any thread remnants, reattach the headframe, and tighten the screw.
