Troubleshooting Common Sewing Machine Problems: A Guide for Stitchers

There’s nothing more frustrating than sitting down to sew—full of ideas and inspiration—only to have your machine jam, skip stitches, or refuse to sew altogether. Whether you're a seasoned stitcher or just starting your sewing journey, running into machine issues is almost inevitable. The good news? Most problems have simple solutions you can tackle at home.

In this blog, we’ll walk you through the most common sewing machine troubles, explain what causes them, and show you how to fix them quickly and confidently—so you can get back to doing what you love: creating. Keep reading for practical tips, step-by-step checks, and a few expert tricks you might not have tried yet.

🧵 Quick Troubleshooting Checklist

Before you start adjusting parts or reaching for the screwdriver, run through this basic checklist—many sewing machine problems can be solved with one of these simple steps:

✅ Is the machine threaded correctly?
Double-check both the top thread and the bobbin. One missed step can throw everything off.

✅ Is the needle inserted properly and in good condition?
A bent, blunt, or incorrectly installed needle can cause skipped stitches and thread breaks.

✅ Is the bobbin wound evenly and inserted the right way?
Make sure it’s turning in the correct direction and the thread is feeding smoothly.

✅ Are you using the right needle and thread for your fabric?
Mismatch here can cause tension problems, puckering, or breakage.

✅ Is the presser foot down?
It might seem obvious, but it’s a common (and easy-to-miss) mistake that affects tension and feeding.

✅ Are you using the correct settings for your fabric?
Stitch length, tension, and foot pressure all need to match your project.

✅ Is the machine clean and free of lint?
Dust and thread buildup—especially around the bobbin area—can cause all kinds of issues.

✅ Have you turned the machine off and back on?
Sometimes, especially with computerized models, a reset can clear up an error.

1. Is the machine threaded correctly?

Incorrect threading is one of the most common causes of sewing problems. Even experienced sewists can occasionally miss a thread guide or tension disc. Always thread your machine with the presser foot up to ensure the thread slips into the tension discs properly. Don’t forget to check your bobbin threading too—if it's not feeding the right way, you’ll end up with tangled stitches or thread nests.

2. Is the needle inserted properly and in good condition?

The needle must be pushed all the way up into the needle clamp and tightened securely. A bent or dull needle can skip stitches, snag fabric, or break thread. As a general rule, replace your needle every 8–10 hours of sewing, or at the start of a new project—especially if you’re working with heavy or specialty fabrics.

3. Is the bobbin wound evenly and inserted the right way?

An unevenly wound bobbin or one that’s inserted backwards can cause inconsistent tension, noise, or jamming. Ensure the bobbin is wound smoothly and that the thread is feeding in the correct direction (usually clockwise or counterclockwise, depending on your machine). The bobbin case tension should also have just a slight resistance when you pull the thread.

4. Are you using the right needle and thread for your fabric?

Different fabrics need different tools. Lightweight cottons/wovens do well with universal needles and all-purpose thread, while knits require ballpoint needles. Denim, leather, or canvas may need a thicker needle. Mismatched combinations can cause skipped stitches, tension problems, or even needle breakage.

5. Is the presser foot down?

It sounds simple, but forgetting to lower the presser foot before sewing is a very common issue. If the foot is up, the tension discs remain open, and the top thread won’t be controlled properly—leading to loose stitches or a messy back side. Make it a habit to check before you start stitching.

6. Is the machine clean and free of lint?

Lint buildup—especially in the bobbin area and under the feed dogs—can interfere with stitching and tension. Use a small brush or soft cloth to regularly clean your machine, and avoid blowing into it (which can push lint further inside). A drop (just one drop) of machine oil (if recommended in your manual) can also help keep things running smoothly. Not all machines need oiling.

7. Are you using the correct settings for your fabric?

Check your tension, stitch length, and foot pressure based on what you’re sewing. For example, fine fabrics may need a smaller stitch length and lower foot pressure, while thicker fabrics require longer stitches and more pressure. Always test your settings on a scrap piece of the same fabric before starting your project.

8. Have you turned the machine off and back on?

Sometimes, especially with electronic or computerized machines, a quick power reset can clear up error messages or strange behavior. If your screen is frozen, your motor seems unresponsive, or you’ve made several setting changes, turning the machine off and on can refresh everything.

Troubleshooting your sewing machine doesn't have to be intimidating. With a little patience and the right checks, most issues can be solved quickly at home—no panic (or unpicking) required! Whether it’s a skipped stitch or a sudden thread jam, this guide is here to help you stay calm, diagnose the problem, and get back to stitching with confidence.

Keep this blog bookmarked for future reference—and remember, your sewing machine works best when it’s clean (and serviced), correctly threaded, and paired with the right tools for the job.

Don't forget, your machine still needs maintence carried out by a specialist. If you have tried the troubleshooting, with no success, you will need to get your sewing machine serviced/repaired.
