It could be a problem with the needle itself:
Your broken needle may have been blunt, dull, bent or otherwise damaged.
Your broken needle may have been too thin for your fabric. Make sure your replacement needle is appropriate for the weight and type of your fabric and thread. You may also need a thicker needle if you’re sewing through bulky layers of fabric.
And when you insert your new needle, make sure it’s positioned correctly (usually with the flat side away from the bobbin, but consult your manual), that it goes all the way into the holder, and that the screw is securely tightened.
If there doesn’t seem to be a problem with the needle itself, try the following:
Check your presser foot
Make sure it’s attached securely.
Change your presser foot
Your presser foot may be bent, causing your needle to hit it. Also, make sure you’re using the correct presser foot for the type of stitch you’re sewing. For instance, if you were to use a straight stitch pressure foot (it has a smaller needle hole) to sew a zigzag stitch, your needle would hit the pressure foot and break.
Don’t sew over pins
A needle that hits a pin can break. Always remove the pins from your fabric before they reach your needle.
Don’t pull your fabric as you sew
You could be bending your needle back, causing it to hit your needle plate instead of going into the hole. Just guide your fabric, letting it feed on its own.
Check your needle plate
Make sure it's securely in position.
Change your needle plate
If you’ve been using a straight stitch needle plate (a plate with a small hole, often used for sewing fine, delicate fabrics), switch to a needle plate with a wider hole.
Check the position of your needle
Sewing machines with zigzag capability allow you to adjust the position of your needle – right, left, or centre. If your needle is not positioned correctly, it may be hitting your needle plate or presser foot.
By trying the above you can determine where it is something simple causing these problems. If this doesn't help then the fault may be more sinister, it could be needle bar alingment, Needle bar height, Stitch timing and machine synchronization all of the above can easily be caused by bunching or jamming Contact us for free advice and assistance.
