  An error during a software update on your Bernina Sewing Machine can occur 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, and then switch it back on. Follow the instructions on the display, unzip the update data, and save the software update data directly on the data medium, not in a file on the USB stick.

  Skipped stitches on your Bernina sewing machine can be caused by several factors. First, ensure you are using the correct needle system 130/705H. A blunt or bent needle can also cause skipped stitches, so replace the needle. Using a new BERNINA quality needle is recommended. Check that the needle is correctly inserted with the flat side to the back, as far up as it will go into the needle holder, and tighten the screw. Finally, match the needle point to the texture of the material you are sewing.

  Lower thread breakage on your Bernina sewing machine can occur if the bobbin case is damaged, so replace the bobbin case. Another cause could be a damaged stitch hole in the stitch plate, in which case you should contact the nearest specialized BERNINA dealer to have the damages repaired. Finally, a blunt or bent needle can also cause the lower thread to break, so replace the needle.

  If your Bernina sewing machine needle is breaking, several factors could be the cause. Ensure the needle is correctly inserted with the flat side to the back, as far up as it will go into the needle holder, and tighten the screw. Avoid pulling the fabric; instead, feed the fabric evenly. If you are sewing thick fabric, use the appropriate presser foot, such as Jeans foot No. 8. Finally, using quality thread can prevent knotted thread from causing the needle to break.

  Amy WilsonAug 29, 2025
  Faulty stitching on your Bernina sewing machine can be attributed to a few common issues. Check for thread remnants between the thread tension discs; if present, 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 the machine is correctly threaded by rethreading it. Finally, inspect for thread remnants below the bobbin case spring and remove them if found.

Why is the upper thread of my Bernina 770 QE breaking?
- K
  Kevin SmithAug 28, 2025
  If the upper thread is breaking on your Bernina sewing machine, it could be due to several reasons. Ensure that you match the needle with the thread size. If the upper thread is too tight, reduce the upper thread tension. Incorrect threading can also cause this, so rethread the machine. Using poor quality thread can lead to breakage, so use quality thread. If the stitch plate or hook tip is damaged, contact the nearest specialized BERNINA dealer to have the damages repaired. Also, check if the thread is caught in the area of the thread take-up lever and remove the screw (1) on the headframe with the angular Torx wrench. Then, attach the headframe and tighten the screw. Finally, ensure there are no thread remnants.

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.

  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).
