Tips for Sewing Machine Troubleshooting
TIP #1: Troubleshooting Power
If your machine won’t even turn on, then check everything is plugged in correctly and switched on at the wall.
Power issues mean a trip straight to a sewing machine technician as you should never attempt electrical work yourself.
TIP #2: Troubleshooting Tension
If your machine is not sewing nicely or is sounding strange, your tension may be too tight or too loose.
Test a scrap of fabric and see if the upper and lower threads are both even and uniformly formed. If either the top or bottom thread is loopy, you will need to adjust the tension.
This diagram should help you visualize the tension a little better.
- Upper thread and bobbin thread are balanced – no adjustment needed
- Upper thread too loose or bobbin too tight – increase tension (higher number)
- Upper thread too tight or bobbin too loose – decrease tension (lower number)
When sewing machine troubleshooting, make any adjustments slowly until you get it right. Big turns of your tension dial can cause more problems or new problems.

TIP #3: Troubleshooting Needles
Check for bent, blunt or broken needles. If your needle is not in perfect condition, it can cause skipped stitches and needles to break.
Also, ensure you are using the correct type of needles for the fabric and in the correct size.
Here are just a few needle weights and types.

| FABRIC WEIGHT | SEWING NEEDLE SIZE |
| Very Fine | 8/60, 9/65, 10/70 |
| Fine | 11/75, 12/80 |
| Medium | 14/90 |
| Heavy | 16/100 |
| Very Heavy | 18/110 |
| Extra Heavy | 20/120 |
| FABRIC TYPE | MACHINE NEEDLE TYPE |
| Lycra/Spandex | Stretch Needle |
| Leather/Vinyl | Leather Needle |
| Woven | Universal Needle |
| Knits/Stretch | Stretch or Jersey Needle |
| Denim | Denim or Jeans Needle |
Make sure the needle is inserted correctly. The flat part of the needle should be facing towards the back of the machine and the screw should be tight.
TIP #4: Troubleshooting Threads
Next on our list of sewing machine troubleshooting, is to check the thread used in the top spool and bobbin.
Don’t use cheap threads that may break or run through the tension disks unevenly. Also check if your thread is knotted, twisted or caught. The thread may be twisted and caught around the bottom of the top spool.
Did you know that there are different types of threads for different fabrics and purposes? Make sure your thread matches your fabric.

TIP #5: Troubleshooting Dust and Dirt
A dirty machine cannot function at its best so start cleaning. Ensure the power is turned off and the cord removed before you start. Don’t forget the bobbin case and tension disks as this is a common spot for thread tangles and clumps of fluff.

TIP #6: Troubleshooting Threading
Even if your machine looks correctly threaded, rethread it now. Don’t forget to rethread the bobbin! When threading your machine make sure the needle is in its highest position. The thread needs to go securely through the tension disks.

TIP #7: Troubleshooting Bobbins

TIP #8: Troubleshooting the Knobs
If the machine needle is not moving at all – Check the bobbin winder is not engaged.
If little fingers have been playing with the buttons on your machine, you may have to reset them. Or maybe you just forgot to switch it back across after bobbin winding.
TIP #9: Troubleshoot Stitch Type
When doing sewing machine troubleshooting, check all the stitch dials. Is the stitch type correct and is the setting locked in and not halfway between two settings? Is the stitch length and width correct? When troubleshooting it is best to have your settings on a straight stitch.
TIP #10: Troubleshooting Throat Plate
If your throat plate has been nicked by you sewing over a pin it will snag the bobbin thread and cause tension problems. New throat plates are inexpensive and readily available from most dealers.
