This is often caused by incorrect threading of the top thread, not the bobbin. Rethread the machine entirely, making sure the presser foot is up while threading.
This can be due to using the wrong needle size, sewing over thick seams, or a bent needle. Replace the needle and make sure it’s appropriate for your fabric.
Check that the presser foot is down and the feed dogs are engaged. Also verify the machine isn’t set to a zero stitch length.
Old or low-quality thread, incorrect tension, or a burr on the needle plate could be the culprit. Try rethreading, adjusting tension, and switching to a fresh, quality thread.
This usually means it needs cleaning, oiling, or has lint built up in the bobbin area. Stop sewing and schedule a service if the sound persists.
The feed dogs might be down or the stitch length is set too low. Make sure the feed dogs are engaged and try a longer stitch length.
A dull or bent needle, or incorrect threading, can cause this. Change the needle and rethread the machine carefully.
Check if the needle is inserted correctly and if the machine is threaded properly. The timing may also be off, which requires professional service.
Unplug the machine and check for thread jams under the needle plate. If there’s resistance when turning the handwheel, don’t force it — have it serviced.
I recommend a full service every 12 months or every 100 hours of use — whichever comes first — especially for machines used regularly or for business.
