Top thread doesn't pick up bottom thread.

Could be

1. Bent needle
2. Needle not inserted into holder properly
3. Top or bottom not threaded per machine instructions
4. Extreme top thread tension
5. Debris in hook, race, or bobbin case
6. Damaged hook
7. Timing

Generally, the top thread picks up the bobbin thread.
Try installing a brand new needle. Old, dull, or bent needles will frequently have problems. You should change the needle about every 8 hours of sewing time (cheap insurance to avoid problems).

If a new needle doesn't help and you've verified it is threaded correctly, then your machine has probably been knocked out of time. Search for "sewing machine timing" or take it for service.

Try installing a brand new needle. Bent or damaged needles sometimes do not contact the bobbin thread to pick it up.

Usually threading is not an issue, but you may want to rethread the machine (be sure to always RAISE the presser foot during threading).

If it still doesn't pick up the bobbin thread, most likely the needle/hook is out of time. Take it for service.

try adjusting the top tension to 3 & if it doesn't stop the looping, try 4 but I wouldn't go any higher than 5,, if changing the top tension doesn't help then I suggest taking the machine in to have it serviced. the bottom tension is more difficult to do,, it's also very possible that the top tension dial is messed up & needs replacing. only a sewing machine shop can tell for sure.

A. To correct loose stitches, try the following: (1) Balance the thread tension. If the stitches are loose on top of the fabric, decrease the tension to the next lower number. If they are loose on the underside set the tension to the next higher number. (2) Make sure the needle/upper thread follows the threading path. (3) Check to see that the bobbin case is threaded properly. (4) Use a different size needle. For fine fabrics, use a smaller needle (size 9, 11); medium-weight fabrics require a size 14 or 16. And use a size 18 or "Denim" needle for heavy corduroy or denim.

check your needle again flat side of needle to the back if this is not your problem then u are out of time. needs servicing.

The most common reason the bottom thread won't pick up is because the needle is inserted wrong. Check that the needle is inserted with the flat side of the needle shank is facing away from you.

Hi! This may sound silly, but if you changed your needle and put it in backwards (which is easy to do), the top thread won't pick up the bottom thread. Take your needle out and check the flat side of the needle shank--which way is it facing? With a lot of the newer machines, the flat side goes to the back, but check your manual to make sure.

Let me know if this helps, ok?

Happy Sewing!

My sewing machine is a Brother LS1217, well actually it is my son's, and he uses it very seldom. I went over to put in a new needle and I cleaned it top and bottom, put in a new bobbin, and a new needle and the needle won't pick up the bottom thread. What am I doing wrong? Please help me!! It has to be something simple, as this is such a simple machine! [email protected]
