What to do if my Bernina 790 Sewing Machine skips stitches?
- E
  Edward GrayAug 20, 2025
  Skipped stitches may occur if you're using the incorrect needle; ensure you are using the needle system 130/705H. A blunt or bent needle can also cause this, so replace the needle. Using a new BERNINA quality needle is recommended. Verify that the needle is correctly inserted with the flat side to the back, as far up as it can go, and that the screw is tightened. The issue could also be due to an incorrect needle point; match the needle point to the texture of the material.

What to do if there is an error during software update on my Bernina 790?

  Emily GrahamAug 22, 2025
  If you encounter an error during a software update, it could be due to several reasons. If the USB stick is not recognized, use a BERNINA USB stick. If the update process is blocked and the hourglass on the display is inactive, remove the USB stick, switch the machine off, switch it back on, and follow the instructions on the display. If the date of the software update cannot be found, unzip the update data and save the data of the software update directly on the data medium, not in a file on the USB stick.

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

Why is there uneven stitch formation on my Bernina 790 Sewing Machine?
- G
  Gina LeeSep 3, 2025
  Uneven stitch formation 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. It could also be due to a poor quality needle or thread, so ensure you are using quality materials and that the needle matches the thread size. Also, check if the machine is incorrectly threaded and rethread it. Avoid pulling the fabric and feed it evenly. Finally, make sure you are using the supplied bobbin case with triangles.

What causes faulty stitching on a Bernina 790?
- A
  Alyssa SandovalSep 7, 2025
  Faulty stitching in your Bernina sewing machine can arise from a few common issues. Check for thread remnants between the thread tension discs and, if found, fold a piece of thin material and slide the folded edge (not the raw edges) between the thread tension discs to remove them. Also, ensure that the machine is correctly threaded by rethreading it. Finally, inspect for thread remnants below the bobbin case spring and remove them if present.

What causes my Bernina 790 Sewing Machine needle to break?
- A
  andrew96Sep 9, 2025
  Needle breakage can occur for several reasons. Ensure the needle is correctly inserted with the flat side to the back, as far up as it will go, and tighten the screw. Avoid pulling the fabric; instead, feed it evenly. If sewing thick fabric, use the correct presser foot, such as one designed for jeans, and use the height compensating tool when sewing over a thick seam. Finally, using quality thread can prevent knotted thread, which can also cause the needle to break.
