Singer Sewing Machine Bobbin Case; Problems and Solutions

Let us know some of Singer sewing machine bobbin case problems and solutions


#1. Bobbin case making noise

If you hear a strange noise coming from the bobbin case (or around that area), clean the machine first. The sound could be caused by the needle striking something within the machine, or you might catch a piece of thread or cloth somewhere.

I opened up the bobbin case with a screwdriver, then removed the loose screw that seemed to have been causing the problem. After putting everything back together, I examined it for any other problems and found none, so my bobbin case seems to be back to normal.


#2. Check the bobbin case for burs

The bobbin is usually placed in a drop-in system with the newest versions, whereas older models (as well as new ones) use a front-loading bobbin case. When putting the bobbin into the bobbin casing, make sure you’re following the manual. If you’re used to working on a different machine, this type of equipment might thread differently than you’re used to.

It would help if you double-checked your machine before continuing. For example, find out whether the bobbin is on the front of the machine (able to be seen from the front) or if there’s a flat piece of metal beneath the footer.


#3. Front-loading machines (vertical)

A metal bobbin casing will be found on every front-loading washer. This is beneficial because we may quickly repair a needle striking the case (in most cases). Remove the hook and examine it for burrs.

When the needle is punching up and down, it might inadvertently strike this region, leaving a mark, especially if the machine isn’t in perfect time. If that’s the case, give it a polish with a tiny nail file.


#4. Loose bobbin case

A loose bobbin case is a problem that typically occurs during sewing. If you experience threads coming out of the area where they’re not supposed to, it might be because the bobbin case is loose and moving around in the machine.

You can fix this by removing the bobbin case and securing it more tightly with a piece of tape. The most excellent suggestion is to take it to a professional to have it fixed since it could not be handled by doing it yourself.


#5. Bobbin case stuck in a sewing machine

The Singer sewing machine bobbin case can sometimes get stuck in the machine when you’re trying to remove the needle from the bobbin. Try to use a screwdriver or key to gently pry the stitching whorl and bobbin case away from one another, and it should stay in place while you turn the knob and manually take out the bobbin case.

You need to get a flashlight and shine it into the depths of the bobbin case and see if you can spot the lint, etc. If so, take a pair of tweezers and pull the lint-free. If this doesn’t work or you cannot see the little lint, then you will have


#6. Bobbin not catching

A common Singer sewing machine problem is a bobbin that won’t catch. This can be a tricky problem to fix, but there are some things you can do to get it working again. First of all, make sure you have the correct type of bobbin for your machine. For example, if your machine is mechanical, you need a metal bobbin instead of a plastic one.

You also want to make sure that the needle threader is working correctly and that the tension on the threader is strong enough to keep the bobbin from slipping out of place when it’s supposed to wind up with thread. It also might be helpful to try using a lubricant like WD-40 or sewing machine oil to overcome friction and make it easier.


#7. Bobbin case not turning

Some Singer sewing machine problems are the bobbin case not turning. This is usually caused by either a needle or any other metal object blocking the path of the bobbin. The first step is to remove any foreign objects and then run a piece of thread through to see if it fixes the problem.

If it doesn’t, you’ll need to take your sewing tool kit out and disassemble the top part of your machine to get to the backside of the bobbin case and remove any metal shavings.

If this does not solve your problem, make sure that there isn’t liquid inside your bobbin case, which could be causing lubricant or liquid on wires or cables, which can be one of the most frustrating Singer sewing machines problems.

You might also consider making sure that your bobbin case is appropriately seated by pulling up on it slightly, which will either solve the problem or help you find out whether this is where your issues stem from. If your bobbin case isn’t turning after trying these steps, you might have a defective part.


#8. Bobbin carrier not moving

A common Singer sewing machine problem is the bobbin case carrier not moving. This can be caused by several different things, some of which are simpler to fix than others. Make sure that you’re working on a Singer model where the bobbin carrier can be fixed by removing it to get at the underside of the carrier.

If you have a model where this isn’t possible, you’ll need to remove your sewing kit and disassemble your machine to fix it. If there are no foreign objects inside the bobbin case, check to ensure that the needle threader is working correctly.

If it isn’t, you can either remove and wipe down the needle case or consider replacing it altogether, as the problem may stem from there.


Frequently Asked Questions (FAQs)

Here are the answers to common questions:


How do you fix a Singer’s bobbin case?


How do I know if my bobbin case is broken?


Why is the bobbin case not spinning?

First, your bobbin thread tension may be too tight. The second source may be because of an unevenly wound bobbin thread. You’ll need a new bobbin and a slow wind of the thread to solve this problem.


When should I replace my bobbin case?

It’s possible to use the same bobbin case for several years. As long as you treat your bobbin case well, it will last long. However, it will eventually stop sewing smoothly and need to be replaced. Some individuals believe they are only required to change specific components of the bobbin casing, such as the tension spring or tension screw. It is recommended that you replace it when you see any of the following: 

#1. The rubber band was stretched and worn out.

#2. The little metal bar (or bobbin case carrier) is bent or deformed.

#3. The rubber band has flattened and is no longer elastic.

#4. Excessive lint accumulation on top of the tension discs.

  1. did not answer my issue. Bobbin thread catches and wraps back around the bobbin. Machine jambs, case moves out of place and I brake needles.

    • Hi Karen

      The upper thread is incorrectly threaded. Try to correct the upper threading

    • Hi Karen
      My new M2100 came with a plastic bobbin case, which will not load thread.

      It does not “Click” in place on the bobbin winder metal pole as in the video, but merely sits there as the metal pole spins. Tried the bobbin case upside down, ith more pressure, holding it up to connect, nothing works.
      Is this bobbin case defective, or is the machine?

  2. I have the Singer 31-20. When I move the stitch length to zero, and turn the hand wheel; the feed-dog hits (makes contact) the bobbin case carrier. Why is this? Is it supposed to do this?
