Why does the upper thread keep breaking on my Necchi C360?
- DdmayerAug 18, 2025
The upper thread may break due to several reasons: * The machine might not be threaded correctly, so rethread the upper thread. * The thread tension could be too tight; reduce it to a lower number. * The thread might be too thick for the needle; select a larger needle size. * The needle may not be inserted correctly; remove and reinsert it with the flat side towards the back. * The thread could be wound around the spool holder pin; remove the reel and wind the thread onto it. * The needle might be damaged; insert a new one.
