Why does the sewing machine no longer make stitches?

Is your sewing machine no longer making stitches correctly? Don’t let this setback ruin your project! We will thoroughly examine the most common culprits of this scenario.

Discover the frequent causes related to thread tension, the needle, or threading and adopt a pragmatic approach to diagnose and solve these problems. This article offers concrete steps to optimize your machine's performance and prevent recurring breakdowns.

Common problems when your sewing machine skips stitches

Proper sewing machine maintenance is essential to prevent your machine from no longer making stitches correctly. When your sewing machine stops making stitches properly, several common causes can explain this malfunction. The needle may be dull, bent, or not suitable for the fabric.

Another cause can be the thread tension. If it is too loose or too tight, it can affect stitch quality. Incorrect threading or a bobbin problem also disrupts sewing. These simple-to-check elements often allow you to solve the problem quickly.

A methodical diagnosis is important to identify the source of the problem. Ignoring signs of poor adjustment can lead to uneven seams, puckering, or even damage to the fabric.

Incorrect tension causes loose or tight stitches, compromising the strength of the seam. It is important to act quickly on these settings to ensure optimal results. Regularly checking key components prevents repeated breakdowns and extends the machine's lifespan.

Diagnosis and resolution of irregular stitch problems

When your sewing machine no longer makes stitches correctly, it is essential to quickly identify the source of the problem. Irregular stitches often come from defects related to the needle or threading, as well as incorrect tension settings of the thread or bobbin. Here is how to diagnose these common causes and resolve them effectively to restore flawless sewing work.

Problems related to the needle and threading

As mentioned earlier, a damaged needle or incorrect threading of the upper thread disrupts stitch formation. A bent or dull needle causes skipped stitches, while a thread improperly inserted in the tension guides causes jams.

Also make sure to choose your needle according to the fabric: knowing which needle for which fabric helps prevent many malfunctions. Check these elements before undertaking more complex adjustments on your sewing machine.

Carry out these checks or adopt these good habits before using your machine: 

• Check the needle condition: replace it if it is bent, dull, or improperly inserted to avoid skipped stitches.
• Use the correct needle for the fabric: choose a needle suited to the thickness and type of fabric for optimal sewing.
• Strictly follow the upper thread threading path: make sure the thread passes through all guides and tension discs.
• Check the bobbin winding: evenly wound thread ensures smooth unwinding and prevents knots under the fabric.
• Properly insert the bobbin into its case: follow the direction of unwinding and the notches provided to avoid stitch problems.

To replace the needle, loosen the screw, remove the old one, and insert a model suitable for the fabric. A universal needle works for most light to medium fabrics, while a special jeans or jersey needle meets specific needs. Thread the machine following the diagram indicated to ensure balanced thread tension.

Thread and Bobbin Tension Problems

Incorrect tension between the upper thread and bobbin thread causes loose stitches, loops, or puckering. 

A tension imbalance shows as visible threads on one side of the fabric. This compromises the strength and appearance of the seams, requiring quick adjustment.

To adjust the tension, use the upper thread tension dial (between 3 and 5), then check the bobbin installation ensuring it spins freely without excessive resistance. Balanced tension is recognized by even stitches, without loops or visible thread on either side. Test by sewing a sample before starting your final project.

Maintenance and Prevention of Stitch Problems

To avoid stitch problems, regular maintenance is essential. Frequently clean the bobbin compartment, feed dogs, and needle plate to remove dust. Knowing how to properly oil a sewing machine is crucial: apply a specific oil to moving parts after each use. Proper lubrication reduces wear and ensures smooth operation of the sewing machine.

Store your sewing machine in a dry place, protected from dust. Prefer quality threads, such as those from the Schmetz brand, to reduce friction and breakage. Likewise, use new needles suited to the fabric, especially if you own a Juki sewing machine, known for its precision and specific requirements. These choices limit debris buildup and preserve internal mechanisms, ensuring even stitches and a long lifespan for your machine.

Stitch problems on a sewing machine often stem from a defective needle, improperly adjusted tension, or neglected maintenance. Act quickly by checking these elements to restore smooth sewing.
