Why is the upper thread breaking on my Lervia KH 4001 Sewing Machine?
- GGilbert BaileyAug 15, 2025
If the upper thread of your Lervia Sewing Machine is breaking, it could be due to several reasons. Ensure the upper thread is correctly inserted. If the tension is too tight, loosen it a bit. Also, the thread might be tangled, so re-thread it. Check that the spool is correctly inserted and that the needle isn't bent or blunt. Finally, verify that the needle size and thread strength are appropriately matched.
