Lots of people wonder, why does my sewing machine keep jamming? As sewing is a complex method, it can be possible that one or two problems altogether causing the jamming.

The quality of threads is more often compromised with the machine quality. People think, as I have a good quality sewing machine now, it can work with low-quality threads. But the case is not so, low-quality threads tend to shred a lot of lint. As a result, thread stuck in sewing machine parts can cause some problems which is not good for the machine.

Low-quality threads also tend to create tiny knots which will not get through the fabric and make the machine jammed.

Though most of the time you will notice that thread jamming in bobbin area but it’s nothing to do with the bobbin keeps jamming problem. The main reason for the tangling of the thread is improper threading. Another reason for tangling is when you do the threading while the feed dog is down. It makes the thread too tight and engages the tension disk.


To avoid bobbin thread keeps jamming problem, follow the instruction comes with the machine properly and threads accordingly. Make sure the feed dog is up when you are threading. If this happens in the middle of your session, unthread the entire machine and again thread it properly as mentioned.

5. Skipped Stitches

The main reason for sewing machines skipping stitches is using the wrong needle. The rule of the needle is, you have to use a ballpoint needle for knit fabric and a sharp needle for woven fabric. But yet if you find yourself changing the needle over and ever again then maybe you are forcing the fabric instead of feeding it into the machine itself. It can cause needle bending.


So make sure you understand the needle properly and when to use which one. The right kind of needle usage can save your machine from many upcoming problems.

6. Broken Needle

Many times, broken needles can be the reason for the jammed machine. A needle can be broke or bent for many reasons. For example, excess time of usage, sewing on improper fabric, using improper thread, etc.


It is recommended to change the needle after ten hours of use or until you finished 2-3 bobbins. Try to stick with this rule. A needle is a tiny part of a sewing machine but it can put a huge impact if not treated properly.

7. Frozen Sewing Machine

For irregular use or negligence, a sewing machine can be frozen. It happens when lint, dust, debris sits on the oiled machine parts for a long time and crystalize. Broken machine parts are also the reason for the frozen machine. Those can cause a common problem such as sewing machine jams after few stitches.


It’s not an easy task to unfreeze the sewing machine. But yet you can try at first checking the bobbin area. Remove it and check if it’s broken or has a built-up crystal of dust around it. If the bobbin is clean then remove the machine top and side cover and check every part of the machine thoroughly. Clean any kind of built-up residue and try to start the machine.
