Why does my Bernina 555 QE keep breaking the upper thread?
- TTonya SmithAug 22, 2025
If the upper thread breaks frequently, several factors could be at play. First, ensure that your needle and thread are a compatible match. If the upper thread is too tight, reduce the tension. Rethread the machine to rule out threading errors. Use only quality thread to prevent breakage. If the stitch plate or hook tip is damaged, contact a specialized BERNINA dealer for repairs. Also, check the thread take-up lever area for any caught thread; remove the headframe, clear any remnants, and reattach it.
