Question about Brother LS-2125 Mechanical Sewing Machine

1 Answer

Thread jamming Hi, After I thread the machine, and when I begin to sew, the thread jams and then the needle won't go down anymore. I took the front off to see what was happening, and the thread is looping down and catching on the metal apparatus, then jamming so the bobbin won't turn, nor the needle go down. I don't understand why it is doing this. Thank you, Jennifer

Either the thread is not in the take up lever or it is not in the tension properly or the tension is set too low or you have the wrong bobbin in the machine or there is a piece of thread stuck in the tension assembly.
To test the tension, set it at 4 or 5, draw the thread through it with the presser foot lever in the up position. Once the thread is in the tension, lower the foot then pull on the thread between the tension and the take up lever. It should have tension on it. Raise the foot and pull on the thread. It should have no or very little tension on it. If it is loose, whether the foot is up or down, you probably have thread stuck in your tension discs. If so, set the tension at zero, open the discs with a small screw driver and blow between them with some compressed air. Sometimes you have to dig it out with tweezers.

My Bernette 715 isn't picking up the bobbin thread and is getting jammed. Any ideas what's wrong?


First thing to always try: Install a brand new needle. A dull, worn, or bent needle will cause great frustration. It is also the least expensive resolution to most problems.

Second: Remove all the threads. RAISE the presser foot. Rethread from the beginning making sure it is threaded correctly.
Pull up the bobbin thread before beginning to stitch and hold the thread tails in the left hand while slowly taking the first few stitches:

How and Why to Bring up the Bobbin Thread

If still having issues with not pulling up the bobbin thread, the needle/hook may be out of time.

Keeping the thread in needle when you begin to sew


after threading the needle pull about 6" of thread out the back under the press foot
that way the thread is jammed under the foot and is held in place for the next thread
bobbin thread should also be out the back
when you have finished sewing then lift the foot and move the material sewed about 6"" away from the foot before cutting the threads

My sewing machine is jammed the needle will not go up or down nor does the wheel


Stop! Get your camera/cell phone or whatever. Take pictures at each of these steps (to refer to later)

Remove the needle and presser foot (use scissors to cut threads if necessary)

Remove the plates under the presser foot that cover the bobbin and needle through area. Clean any thread/lint, etc from under there.

Get magnifying glass and inspect for additional bits of thread or needle ends that have broken off.

If necessary remove the shuttle race and inspect for burrs, cracks, etc.

replace everything and try moving the handwheel. If it works, it's good to go. If it doesn't take it in.

Now... when you begin sewing any seam. ALWAYS grasp both threads as you begin sewing. This will keep jams from happening and it is a good sewing habit.

I was sewing with elna machine and ran out of thread. This caused the thread to ball up underneath and "jam" the machine. I cleared it out and rethreaded it, but now the top thread doesn't catch the bobbin...


it is possible that the sewing machine has a timing problem, but check to see if the needle is inserted correctly into the needle holder
make sure the bobbin is inserted correctly into the bobbin case if the machine has a top loading bobbin
if the machine has a side or front loading bobbin also make sure the bobbin case is inserted correctly into the machine.
and also make sure the top thread has not come off the thread take up lever

Needle won't remain threaded


make sure the thread has long thread tails of 4 to 6 inches long
and have the thread tails pulled behind the needle before starting
to sew.

My thread often becomes unthreaded from the part that raises and lowers the needle causing the thread and fabric to jam up


Your needle should not come unthreaded in the middle of sewing.. if it does, it is because the thread breaks. this can be a simple tension problem or brittle thread.

if you are talking about at the beginning of sewing that the needle comes unthreaded, then you should just pull out 6-8 inches of thread through the needle before putting your fabric under and begin sewing.

i hop that helps.
