    No worries. Just sit it back in. You may need to fiddle with it a bit, upside, downside, but you’ll find the sweet spot eventually to where itfits back in nicely. Then put the bobbin and bobbin case back in by pulling up the small lever on bobbin case and putting it back into the large ‘metal bits’. If seated properly, you will hear a ‘click’.

SOURCE: Singer Sewing Machine model 9224. Bobbin thread

If you turn the handwheel, can you see a metal ring rotating around the outer edge of the bobbin case? If not rotating, broken gear or timing belt off.
If that ring is turning, remove the needle plate and bobbin case. As this ring now rotates, you will a finger on the ring that will pass behind the needle from right to left and it should catch the thread from the eye of the needle. If this finger, the "hook" passes above the eye, you have a timing problem.

Let me know.

SOURCE: thread knotting around bobbin case

hello, I had the exact same problem and could not find the solution until i took my machine to my sewing sensei and i solved my tedious problem. It was actually not a tension problem at all but a threading problem. Make sure you have threaded your bobbin correctly and that when you pull on the bobbin thread that the bobbin turns the right way. (mine must spin anti clockwise to work)  Make sure that when you pull up the bobbin thread using the needle that it is not over the feed dogs connective bar but under it. A big problem when the thread gets caught around the bobbin case wheel is that the thread is looped around the feed dogs once and that causes the thread to get caught around the bobbin wheel. In conclusion, thread the bobbin correctly and read over your instruction book before spending the money to get it fixe in s shop.

SOURCE: 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.

SOURCE: Bobbin Case

I'm having a similar problem today. I took out the bobbin case and when I went to put it back in, the whole system locks up. I've tired cleaning, changing needle taking the metal plate and piece that holds bobbin case out and put it all back in after cleaning. Nothing. My symptom is I can't get a complete stitch, the needle goes down, the whole deal acts like it will work and as soon as the arm of the bobbin case gets to 8 o' clock on the gears, It jams and won't hardly move. I cannot pull the bobbin case out easily after this. Perhaps there is someone out there that can help us!

Bobbin case inserting wrong


I suspect the "housing" you refer to is not seated completely. Be sure to wiggle it until it slips into place. Once it is seated, the bobbin case should seat firmly as well.

Re-curring loose bobbin case


According to the manual, this is a drop-in bobbin.

If the bobbin case came loose, the needle would probably hit it and brake.

Take the bobbin out.

Turn of the power and remove the needle plate (under the presser foot).

Raise the needle to it's highest position and lift out and reset the bobbin case into the shuttle. This should be in the maintenance section of the manual. The bobbin case should fit snug.

Make sure the thread is feeding from the bobbin, counter-clockwise and through the guides on the bobbin case.

For a rotary bobbin with a metal bobbin case.

Remove the bobbin case. Make sure the thread is feeding clock-wise and through the guide on the side of the bobbin case.

Raise the needle to it's highest position - this puts the hook at the lower left. Left the tab on the back of the bobbin case and slip the bobbin case back into the shuttle with the "arm" straight up. You may have to move the bobbin case a bit to the left or right for it to snap into place.

If the problem persits, take the machine back to the dealer - there should not be a charge for fixing this as it is brand new - keep your receipt and warranty information at hand.

Now you need to adjust the tensions, make sure you thread the machine with the presser foot up, top tension should be about 4 or 5, you should be able to pull the bobbin thread through with slight resistence, if it is too tight slacken the large screw on the bobbin case about a quarter of a turn at at a time anti clockwise and test sew until you get it right, do not use very thick threads.

Bobbin Thread Doesn't Join the Upper Thread


Have you lowered the presser foot lever? It is the lever behind the needle that makes the foot go down. Do you put the bobbin in the machine from the top of the machine or from the front? In either case, you need to make sure the bobbin thread has clicked into the tension slot in the bobbin case. The bobbin case is the part of the machine that the bobbin sits in. It will have some kind of narrow cut out with a thin metal shaped piece half covering the opening. The thread has to go down into the cut out piece and click down beside the metal piece. You will hear a faint "click" when it is in place. Very hard to describe, but easy to show someone! Write back if this is not helpful to you. Also tell us your machine model.

How do you adjust the bobbin tension on a Singer 533....When I use mine..the top thread from the needle is fine but the underside thread is a mess, all tangles etc. Any ideas anyone???


With your slide plate open, you will see 2 screws on the bobbin case. You need to adjust the one on the inside (not the one that sits at the edge of the metal strip). Do so very slightly. If you can't seem to get it adjusted, take a look and make sure there isn't any thread or lint in between the two pieces of metal that the thread feeds through. This can cause a loose tension.

My Bernina 930's lower tension is off. When I sew the stitches are tight on top, but loose on the bottom. How can I fix this? I've tried messing with the tension and have cleaned the bottom.


Hi - you might have a dirty bobbin case, or need a new one. IAfter awhile, little teeny dust bunnies can collect in your bobbin case and cause your bobbin tension to go wonky, especially if you use cotton thread. If you happen to have an extra bobbin case, try using the new bobbin case to see if that solves the problem. Otherwise.....
  • Remove your bobbin case and take out the bobbin. Find a small, stiff brush like the one that came with your machine and stand in very good light. Brush out the inside of your bobbin case, and push one or two bristles of your brush into any opening you can see. If you see any trace of dust but you can't get it out, use tweezers to gently pull the dust out. Now look at the outside of your bobbin case. In the small opening where you insert your bobbin thread into the bobbin case, there is a small piece of metal with screws in it the lays over the bobbin case. Brush that area carefully, and again, insert one or two bristles under than piece of metal and into any other small opening where the bristles will fit. Try sewing again. If you are still getting loops, take out your bobbin case with the bobbin thread still inserted and grab the bobbin thread with two fingers. Let go of the bobbin case - sort of like you are holding a yo-yo. If the bobbin case starts to drop as soon as you let go, your bobbin tension is loose. If the the case doesn't move, gently snap the bobbin thread you are holding and see how far the bobbin case moves down toward the floor (you might need to try this a couple of times, the bobbin has a nasty habit of flying out). When you do the snap, the bobbin case should move down about two inches and stop. If do not know how to adjust the bobbin tension, either check your manual or take the machine in for service.
  • If you haven't already, it's a good idea to remove the thread plate that sits under the needle and clean that area out with your brush. Also, get a really good flashlight and check the area where you insert your bobbin case. Gently turn your fly wheel and look inside the hook area - remove any dust or bits of thread.
In general, you should oil your machine as indicated in your manual as often as directed. You should change your needle every 10 hours of sewing - or each time you start a new project, and you should take your machine in for service every one or two years - even if you only use it once and awhile.

Hope this helps, Ginny

Bobbin thread breaks


Make sure your bobbin thread is turning clockwise as it sits in the bobbin case. There is a screw on the outside of the bobbin case you can turn with your thumb slightly to adjust tension. If you dangle the case from the thread and give it a light ****, it should move down slightly when doing so-an indicator of good bobbin tension.

Bottom (bobbin) thread suddenly loosens


Good morning,

A few steps to help you troubleshoot:
  1. Bobbin in the right direction: when looking at the bobbin in the bobbin case, pull the thread tail. The bobbin should turn clockwise.

  2. One of the biggest causes of what you describe is simply a burr/rough spot on the needleplate or hook.

    Remove the needleplate from your machine and inspect the opening for any rough spots... run your finger over the area to feel for any sharp bits. If you discover some rough spots, they can be smoothed using a fine emery cloth. Use this gently - don't want to distort needle opening, just smooth the roughness.

    If no rough spots on needleplate, open the bobbin cover and turn the handwheel towards you until the hook (little pointy part of bobbin area) is towards the bottom of the machine. Run your finger over the point to feel for any rough spots. Again - a fine emery cloth can smooth this. Be VERY careful to not flatten the hook - just a little smoothing to get rid of rough bits. Too much can ruin the hook. If you're uncomfortable with this, don't hesitate to take to your Pfaff tech and point out the rough bits.

  3. Hold the bobbin case/bobbin between finger/thumb, making sure you're not pressing on the bobbin tension (little flat metal piece on side of case). Pull the thread smoothly out of the bobbin case to see if you feel any little glitches. If you do, there may be a bit of fuzz/broken thread trapped under the bobbin tension.

    You can loosen the large setscrew on the side of the case to allow you to blow out whatever may be trapped.

  4. While your top thread may appear fine, there may be a bit of fuzz or broken thread wrapped around the take-up lever. This would interfere with the smooth feeding of the upper thread, also causing an inconsistency in the bobbin.

    Use a flashlight and look down into the top of the machine/takeup lever area. You may be able to see a bit of thread and remove it. If you can't see an offending bit, try "Flossing" your upper thread path by grasping the thread close to the spool and after it comes out of the needle. Run the thread back and forth through the thread path to see if you can dislodge anything

  5. If none of the above help, we'd suggest you have your local Pfaff authorized tech take a look. It's always a good idea to take your machine to it's respective authorized service person as they'll be the ones to know the most about it and have access to any repair parts.
Please don't hesitate to respond if you need further help or clarification.

Happy sewing,
Kim & Linnette
