What to do if the bobbin thread breaks on Janome 7330?
If the bobbin thread breaks, several factors could be at play. First, ensure the bobbin thread is correctly threaded in the bobbin holder. Next, check for lint accumulation within the bobbin holder. If the bobbin is damaged and not turning smoothly, replace the bobbin. Also, if the thread is wound loosely on the bobbin, re-wind the bobbin.
Why does the needle thread keep breaking on my Janome Sewing Machine?
The needle thread may break for several reasons. It could be that the needle thread wasn't threaded properly, or the needle thread tension is too tight. Also, check if the needle is bent, blunt, or incorrectly inserted. Ensure that both the needle and bobbin threads are properly positioned under the presser foot at the start of sewing, and that you're drawing the fabric to the rear when finished. Finally, the thread might be too heavy or fine for the needle being used.
