To ensure your sewing project turns out flawlessly, there are various factors to consider; some of these include properly threading the machine, using the appropriate needle type for your fabric and inserting the bobbin correctly. Additionally, make sure to cleanse the SINGER M1500 sewing machine on a regular basis! 

If any stitching imbalances occur due to different top and bobbin thread weights even after all this effort it’s important not forget about adjusting tension as one final effort – if done right you should notice that both sides of material feature identical stitches in no time at all!

What are SINGER M1500 sewing machine tension issues?

Thread tension is the amount of thread pulled through a sewing machine to form stitches. Achieving the ideal stitch requires adequate thread tension in your sewing machine. Pulling more or less thread will determine how loose or tight the stitches are, respectively. To ensure you get correctly formed stitches when sewing together fabrics, there must be a harmonious relationship between the top and bobbin threads – an optimal balance of both.

When faced with looping thread, bird nesting or snapped threads while sewing, try adhering to a step-by-step checklist in order to get back on track and sew flawless stitches with your machine.

Ensuring Consistent Tension with Matching Threads

For the best tension results in your SINGER M1500 sewing machine, it is essential that you use identical thread on both the top and bottom of this device. If there’s an imbalance between fiber content or size, then desired tension could be disrupted. To guarantee optimal performance in all areas, make sure to have matching threads throughout.

Maintaining Your SINGER M1500 Sewing Machine: Cleaning and Servicing

To ensure that your SINGER M1500 sewing machine continues functioning optimally, it is essential to clean the bobbin compartment and have it serviced regularly.

SINGER M1500 sewing machine bobbin tension problems

Have you ever wondered what bobbin tension is? What is the bobbin tension? Bobbin tension applies pressure to the thread in a bobbin case, generated by two pieces that are held together with a tiny screw. When this screw tightens, so does the pressure; when it loosens, this causes the opposite effect. The metal plate/spring assembly remains set at an exact tension during production and constantly maintains steady thread tensions as your sewing project evolves.

How Do You Adjust The Bobbin Tension On A SINGER M1500 Sewing Machine?

  1. If you wish to adjust the bobbin tension on your SINGER M1500 Sewing Machine, please make sure to look through the manual of your particular model. This is vital in order for you to familiarize yourself with any applicable instructions and guidelines before carrying out this adjustment;
  2. Test the strength of your stitching by sewing a seam on folded fabric, then tugging gently to see if it will break;
  3. If your machine is only displaying one broken thread, attempt to correct the bobbin tension first;
  4. To gain access to the bobbin area of your sewing machine, detach its faceplate;
  5. Remove the bobbin and its case via the hinged latch but keep the bobbin in the case;
  6. Use a screwdriver that fits the size of the screw on the side of your bobbin case, and turn it to adjust accordingly;
  7. Resist the temptation to exert too much force; instead, make small adjustments to tighten the screw;
  8. To increase the bobbin tension, turn the knob clockwise; to decrease it, rotate counterclockwise;
  9. Tension can be gauged by pulling lightly on the bobbin thread to feel its resistance;
  10. When the thread easy to pull out, it’s a clear indication that the tension is too loose;
  11. When the thread won’t come out, it usually means that the tension is too tight on your sewing machine;
  12. Reinstall the bobbin in the SINGER M1500 sewing machine;
  13. Reattach the faceplate for added security;
  14. To ensure that your seam is properly sewn, stitch diagonally on the fabric as instructed in step 2;
  15. The top and bottom of your stitches should be even, with the center securely locked in place;
  16. Ensure that each thread remains intact when tugged on to guarantee fabric longevity.

When to adjust the bobbin tension on a SINGER M1500 Sewing Machine?

To ensure your sewing machine is working correctly, it’s best to adjust the top thread tension first before making any changes to the bobbin tension. However, if you’re using a very fine or thick thread, you may need to adjust the bobbin tension accordingly.

Make sure to only turn the screw in minor increments and test after each movement so that you can achieve optimal results. Also be aware that manufacturers have already set the bobbin tension for most projects, so use this as your starting point.


Why SINGER M1500 Sewing Machine Bobbin thread showing on top?

If you are seeing loops of the bobbin thread on the right side of your fabric, this indicates that the tension for the bobbin thread is too loose. To fix this, reduce the tension of your needle thread by adjusting the dial to a lower number. This should help correct any issues with visibility of your bobbin thread.

Why SINGER M1500 Sewing Machine Needle thread showing on the underside

The SINGER M1500 needle thread can sometimes appear on the underside of the fabric if the bobbin thread tension is too tight. To fix this, you need to increase the tension dial to a higher number so that the needle thread won’t be pulled too much. This will help create even stitches and prevent needle thread from appearing on the wrong side. In other words, make sure your SINGER M1500 tension settings are correct for smooth sewing results.

When to adjust the bobbin tension?

When sewing, the bobbin thread tension should be adjusted depending on the fabric thickness, stiffness, number of layers being sewn, and type of stitches/techniques being used. Bobbin tension also needs to be adjusted when using different thread weights, a twin needle, elastic thread (e.g. for shirring), and when doing stippling or free motion quilting. If problems with skipped stitches occur due to breaking threads in the bobbin despite adjusting only the upper thread tension, bobbin tension should also be changed accordingly.


To conclude, adjusting the bobbin tension on your SINGER M1500 Sewing Machine is essential for ensuring successful sewing projects. It’s important to adjust both the upper thread and the bobbin tension so that you get even stitches and avoid skipped stitches, loops of thread showing through fabric, or other sewing issues. With patience and practice, you can achieve perfect results every single time! Happy sewing!
