  Rebecca DavisAug 17, 2025
  If your Bernette sewing machine is skipping stitches, there are several potential causes. 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 also important. 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, make sure the needle point matches the texture of the material you are sewing.

Why does my Bernette b70 DECO Sewing Machine have uneven stitches?

  James ThomasAug 20, 2025
  Uneven stitch formation in your Bernette sewing machine can occur for several reasons. It could be due to the upper thread being either too tight or too loose, so try adjusting the upper thread tension. Other potential causes include a blunt or bent needle (replace the needle with a new BERNINA quality needle), poor quality needle (use a new BERNINA quality needle), poor quality thread (use quality thread), an incorrect needle/thread combination (match the needle with the thread size), or the machine being incorrectly threaded (rethread the machine).

  If the lower thread is breaking on your Bernette sewing machine, several issues could be the cause. First, check that the bobbin is inserted correctly. Remove and reinsert the bobbin and pull on the thread; it should run easily. Also, verify that the bobbin is threaded correctly. If the stitch hole in the stitch plate is damaged, contact a specialized bernette dealer to have the damages repaired or replace the stitch plate. Finally, a blunt or bent needle can cause thread breakage, so replace the needle.

  Needle breakage on your Bernette sewing machine can occur if the needle is incorrectly inserted. Ensure you insert the needle with the flat side to the back, as far up as it will go into the needle holder, and tighten the screw. Also, using quality thread can prevent knotted thread, which can cause the needle to break.
