Why is the upper thread breaking on my Necchi Sewing Machine?
- RrhaasJul 27, 2025
The upper thread may be breaking due to several reasons: the zigzag width may need adjustment, the machine might be improperly threaded, the upper thread tension could be too tight, the needle might be bent, or the bobbin case may have scratches or nicks. Try re-adjusting the zigzag width, re-threading the machine, reducing the upper thread tension, replacing the needle, or polishing/replacing the bobbin case.
