  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.
