Why does my Bernina 720 have uneven stitches?
- N
  Noah HicksSep 12, 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 720 Sewing Machine is skipping stitches?
- D
  David SimsAug 21, 2025
  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.

  Faulty stitching on your Bernina Sewing Machine can arise from thread remnants between the thread tension discs; fold a piece of thin material and slide the folded edge between the discs to remove them. Ensure the machine is correctly threaded by rethreading it. Additionally, check for thread remnants below the bobbin case spring and remove them if present.

  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.

Why does the upper thread keep breaking on my Bernina 720?
- M
  Mr. Mark RobertsAug 30, 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.

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

  Amanda LoveSep 1, 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.

  Michelle SantosSep 3, 2025
  Lower thread breaks on a Bernina Sewing Machine may be due to a damaged bobbin case; replace it if necessary. If the stitch hole in the stitch plate is damaged, contact a specialized BERNINA dealer for repairs. A blunt or bent needle can also cause the lower thread to break; replace the needle.
