Question about Kenmore Drop-In Bobbin 505S-21BH Mechanical Sewing Machine

1 Answer

Bobbin won't thread

The bobbin thread won't catch and feed to upper thread. I'm wondering if there's a part missing and I'm not aware of it. It's a 385-1664180 model.

I was having this same problem until just a moment ago...

I simply turned the needle knob in the opposite direction. Instead of turning it away from me, I turned it toward me. This is the opposite of what I was doing with my Singer.

I hope that helps!

When pulling my bobbin thread thru to top my upper thread doesnt go all the way around the bobbin case then it hooks on the little metal arm on top bobbin case on my PE700


The part that holds the bobbin case moves around it after catching the upper thread. Check it and see if it is not working as it should. I wonder if the bobbin is not in far enough.

Big loops under the needle plate. The bobbin case is pulled towards the needle and lifted up in the front.


OK, Nylon thread and vinyl fabric are difficult. Try this:
1. Be sure your machine is *very* clean - no leftovers from previous projects.
2. Take the bobbin receiver out (need a screwdriver to hold the release), clean it and all around it and re-insert. When you re-insert in this machine, hold the release lever with the screwdriver, push the receiver away from you (under the feed dogs) then bring it back toward you so it catches before you release the catch.
3. Use a stitch length just a bit longer than you 'normally' would - 3+ for vinyl.
4. Wind your nylon thread onto a bobbin *very* carefully. It's easy to get it caught so that it won't feed evenly.
5. Be sure your upper thread is in properly, and that it doesn't catch on anything.
6. Adjust your upper tension tighter than 'normal' to accomodate the slippery thread your're using - do this a little at a time, it's easy to miss the 'sweet spot' if you adjust too much.
7. Be sure to bring up your bobbin thread and hold both threads as you start to sew - hold them for 3-4 stitches.
8. Sew slow - this machine can go *really* fast, but don't let it on this project. It will catch better if you take it slow and easy.

Hope all this helps. If not, you'd probably better take it in for service.

I have a brother ls-2125 sewing machine. the upper thread is not catching the bobbin thread properly. help please


  1. Tension
    • Your sewing machine tension controls the rate at which the thread is fed through either the upper section of your machine or through the bobbin case. If your upper or bobbin threads aren't threading properly, sometimes adjusting the tension will correct this problem.
    Timing
    • Your sewing machine works by passing the upper thread through the needle of the sewing machine at precisely the same time the bobbin brings its thread to its uppermost position. If either the needle or the bobbin thread reach these positions too soon or too late, the threads won't interact and create the knots that make the seam. You can throw off your timing by sewing too many layers of fabric or hitting a pin with your needle. See you sewing machine repair facility to correct any timing issues.
    Thread
    • Thread can get snagged or caught in the upper section of your machine or on lint pieces in the lower bobbin section. If your threads aren't catching properly, you may be able to fix it by unthreading and rethreading both your upper thread and bobbin threads.

I have a brother sewing machine. i threaded and have rethreaded and threaded the bobbin over and over. it will not move the fabric and botton thread will not catch onto top. what am i doing wrong?


Brother machines are usually a very good brand. Sounds like you are having a small problem with threading..........I know how frustrating that can be!
Start over....totally from the beginning. First, clean the machine of all dust, I use a small paint brush to remove lint from the bobbin case area. Oil the machine. Remove all the thread from the machine, use a different bobbin and rewind it with new thread. Make sure the bobbin thread is the same as the thread you use to thread the upper needle with. Use a new needle that is the appropriate size for your sewing project. Check to make sure the feed dog is moving when you turn the wheel that raises the needle up and down. New needle, new bobbin, new thread......before you place the fabric under the presser foot (and with the presser foot raised), turn the wheel one complete rotation to allow the upper needle thread to catch the bobbin thread. Gently pull both threads out towards the back of the machine, making sure the bobbin thread is now coming up through the little hole in the feed dog plate. Place fabric under the presser foot, lower presser foot and as you slowly start to sew, make sure you have the bobbin thread pulled with slight tension out from the back of the needle. This will take up any slack in the bobbin thread and keep it from making a knotted mess. Good luck, I hope this helps.

Not picking up the Bobbin thread


Sounds like you have to take off the throat plate and clean out threads under it.  Sometime they ball up and prevent the needle from going down and catching the bobbin thread. You can't see themuntil you take off the plate.  Follow the directions.  It is easy.

Brother 3022 Mechanical Problem


Make sure your needle is in correctly. Check your threading again. If that does not work, remove throat plate, install new needle, turn hand wheel until needle is at its lowest position and observe if the hook is exactly behind the eye of the needle. If that is correct then you do not have threaded correctly. If it is not then the machine needs to be re-timed.

Bobbin thread won't catch


I've just had this exact problem with my model 2037. The problem, according to 3 shops I've taken mine to, is that the shuttle hook (the metal piece that the bobbin sits in) is broken and needs replaced. Problem is, the piece is next to impossible to find.
