What Are The Brother Sewing Machine Cs6000i Bobbin Case Problems

Brother Sewing Machine Cs6000i Bobbin Case Problems

The bobbin is a small, spool-shaped container that holds the thread used in sewing. It’s located right next to the needle on your sewing machine; and while it may seem insignificant and hidden, that little coil of thread under the needle is perhaps one of the most important components of a sewing machine. Without it, you wouldn’t be able to get any job done, no matter how basic the job is. That said, sewing machine bobbin problems are fairly common, but they’re also just as easy to fix at home or by yourself.

If you’ve ever done any sewing, you’d know how important the bobbin is. A machine’s job is basically to loop a bobbin of thread around a needle and then pull the two together, creating a stitch. It might appear to be insignificant, but without it, you wouldn’t be able to sew anything on your own. 

That said, if something goes wrong with your machine’s bobbins and you’re not entirely sure what’s wrong with it or where to start in fixing the problem, then all you need is some patience and a little knowledge about sewing machine problems.

1. The Needle Does Not Catch the Lower Thread

The most noticeable problem with a bobbin occurs when the needle does not catch the lower thread, thus creating an incomplete seam. This can be annoying and potentially ruin a sewing job, especially if you don’t notice it early enough. This usually happens when you have inadvertently run out of bobbin thread, forgot to put the bobbin in the bobbin case, or have the wrong size bobbin.

Understandably, this can be a difficult problem for newbies who are just learning how to sew. However, even advanced sewers aren’t immune from this problem; I’ve done it myself more than once! The best way to avoid this is to remember to regularly check your sewing machine’s bobbin case and make sure that it’s properly filled with thread. If you’re worried that you might forget or get distracted, put a little post-it note on your machine so you’ll remember. This will also save time if you have to stop midway through your project and fix it.

Quick solution

A quick and easy solution to this problem is to first check that the bobbin thread has not run out, and if so, wind a little more. If the bobbin is there, but the lower thread won’t work, you can try taking it out of the box and reinstalling it. Lastly, if all of this doesn’t work, then replacing the bobbin with one recommended for your sewing machine or winding a new bobbin on the original bobbin (the one that came with the sewing machine) will fix the problem.

2. My Sewing Machine Bobbin Is Making Grinding Noises

If your sewing machine is making grinding noises, don’t panic—there’s probably not a ghost haunting your beloved machine! 

There are a number of reasons why a sewing machine could be making grinding noises. They include a bent or damaged needle plate, an out of alignment bobbin case and spindle, or the coil is not moving freely, is too large for the case, or has some dents and scratches. If you’re hearing this noise while the machine is running, you’ll want to make sure that none of these issues are causing the problem.

Quick solution

A noisy coil can be fixed by changing the coil thread to the recommended size (do not exceed the coil size). You should also check if the bobbin case moves freely by moving it from side to side and oiling it if your machine supports oiling. If there is visible damage to the spool or spool case, you might need to have that repaired or replaced to get rid of the noises.

3. My Bobbin Keeps Jamming the Thread

there are plenty of culprits that cause bobbin winding and threading problems, from using the wrong size spool of thread (the thread is wound on is too narrow) to using a damaged spool (you need to check for burrs). However, more often than not, problems with bobbins are caused by other parts of your sewing machine—most notably the presser foot (aka feeding foot). As you stitch, the presser foot holds down your fabric as it moves beneath your needle through the stitches.

Quick solution

Check if the bobbin is the one that gets stuck – check if the bottom stitch is tangled or if the needle picks up more than one thread. That said, binding occurs mainly if the upper thread lacks tension, the needle is bent or broken, the feed dogs are stuck, or some internal components are stuck.

4. My Bobbin Is Causing Uneven Stitches

This is a very common bobbin problem on brother sewing machine cs6000i models where the bobbin can sometimes cause uneven stitches in the fabric. Some of these models require a specific type and size of the coil, for example, some may not be happy with a plastic coil due to weight. Also, improper winding of the bobbin will cause the bobbin to serve uneven threads.

Quick solution

In most cases, incorrect sewing caused by the bobbin can be fixed by changing the bobbin or winding a new one. If you are using a Singer or Brother make sure you get a spool of the required size as recommended in the user manual or just use the one that came with the machine.

5. Coil Causing Loose Seams

The problem of loose seams, particularly in the shoulders, is often not a problem of the bobbin thread but with the sewing machine needle. If the tension on the lower thread, the bobbin, is set correctly, it should not cause loose seams; however, as machines age and wear out and as needles wear out and become dull, this can happen. If you are still getting loose seams even after adjusting the tension on the upper thread, then a new needle may be needed.

Quick solution

Make sure the upper thread is properly tensioned and see if the needle is reaching the bobbin thread for each stitch. Loose stitching can occur when the wrong needle is used or the wrong main thread tension is set.

6. My Bobbin Can’t Create The First Stitch?

-First, load a new bobbin and make sure the needle can pick up the thread. If it does, then you are good to go. If not, try turning the wheel towards you and letting the bobbin hang from the back of your machine (away from the needle). This will pull on the thread and help it come off of your spool.

Quick solution

Make sure the bobbin is properly slotted in the bobbin case or compartment and moves freely. When winding the bobbin threads, be sure to fill the thread to the recommended size. You may want to experiment by turning the wheel towards you and see if the needle actually picks up the bobbin thread.

7. My Bobbin Is Stuck in the Sewing Machine

This can happen if there are many jams involving the bobbin, a bent bobbin case, or if you used the wrong type of bobbin, it is too large, or the wrong material. 


You have a few options for getting the bobbin or bobbin case out of the compartment. You can take it to a professional who will know exactly how to handle your machine, which may be the best option if you don’t know what you’re doing and don’t want to risk damaging it. If you are familiar with your machine, you can open up the bobbin compartment and try to pry the jammed thread out with a flathead screwdriver. Make sure you’re careful not to damage anything else; if you do, there’s a chance that you won’t be able to get your machine fixed without replacing other parts, too.

8. My Bobbin Winder Is Not Reordering

Bobbin winding or rearranging is one of those activities that most tailors would rather not do. Having to hold the thread through a series of hooks and balance the bobbin as you wind is no fun. It gets worse when you go through the process and still can’t get any thread on the bobbin. This is very common on some older sewing machines and even modern Brothers and Singers models.


Be sure to check your user manual to see how to hook the thread to rewind the bobbin. The hookup and checkout sequence differs from machine to machine, so unfortunately there is no global solution available. One tip, however, is to disengage the needle when winding the bobbin.

9. My coil moves slowly or gets stuck

It is very common to have sewing problems caused by the bobbin case not moving freely or getting stuck, causing jams or skipped stitches. This usually happens if grease and dust accumulate in the coil compartment. It can also occur if the bobbin thread is not attached correctly, or the thread has formed a knot or a problem with the bobbin case.


Open the bobbin case, remove the entire bobbin housing and clean the area around the bobbin. Also, check the bobbin thread for a knot and rewind a new bobbin. See to it that you tie the bobbin thread correctly by guiding it through the opening of the bobbin case.

Related questions

How do you fix the coil tension?

On rare occasions, you may need to change or fix the tension in the bobbin case. To do this, find a screw or hook on the side of the bobbin case and turn it clockwise to tighten and counterclockwise to loosen. This may vary from bobbin case to bobbin case, depending on the model you use. However, it is not necessary to change the bobbin tension for every job unless it is necessary.

Why Is My Bobbin Case Jumping?

The bobbin may come out of the bobbin case for several reasons.

1. You are using the wrong bobbin. Be sure to use a bobbin designed for your sewing machine.

2. The bobbin was not installed correctly in the bobbin case. Remove the bobbin from the bobbin case and reinstall it following the instructions in the manual.

3. The thread was not wound correctly on the bobbin. Wind the bobbin thread correctly.

4. The bobbin or bobbin case is scratched or blunt. Replace the bobbin or bobbin case.

Why Does My Brother’s Sewing Machine Keep Jamming Underneath?

Binding can be caused by a bent needle, improperly attached bobbin, build-up of grease and dust, and incorrect thread. Start with the coil first and see if it needs fixing or retightening, then check that the top thread has the proper tension. Lastly, always make sure your sewing machine is properly maintained to prevent jams caused by the build-up of grease and dust on internal components.

How Do You Fix a Loose Bobbin Case?

If your bobbin case is stuck, you may need to loosen your bobbin tension. To do this, turn the screw on the bobbin case a small amount in either direction (counterclockwise to loosen, clockwise to tighten). A quarter turn or less is usually sufficient. If that doesn’t work, make sure the bobbin case isn’t seized somehow on the underside of your machine. Look for anything that seems out of place or damaged, and try to adjust it or replace it if it’s broken. If you’re still having trouble, check with your local sewing machine repair shop for more help.

Do Bobbin Cases Wear Out?

A bobbin case has many moving parts. You can see the small pulley, spring, bobbin, and thread guide for the needle on a typical machine. All of these parts are designed to work together seamlessly to produce a perfect stitch every time.

The bobbin case is made of plastic and is designed to be durable. However, it will weaken over time, which can cause problems with the stitches you make. All plastic has microscopic cracks that happen during the manufacturing process. The more you use your machine (or any machine), the more those cracks get bigger and deeper.

Why Is My Bobbin Winder Not Working?

The bobbin winder, a small tool designed to wind thread onto a bobbin, is a vital part of the sewing process. The bobbin winder is usually mounted on the sewing machine itself or on the arm of a sewing table. 

Often times the bobbin thread breaks or the stitch quality is not satisfactory when sewing with a plastic bobbin. This could be because the bobbin has been loaded incorrectly or damaged in some way. In this case, you should follow these steps:

1) Clean the spindle shaft by removing dust and debris with a damp cloth;

2) Check if you aligned the groove in the bobbin with the spring on the bobbin winder shaft and pressed down on the bobbin until it snapped into place;

3) Check if there is adequate thread tension when sewing and that there is no excess fabric placed under or around the presser foot.
