Needle Breaking
Janome Sewing Machine
Severity: ModerateWhat Does This Error Mean?
Needles breaking repeatedly means the needle is hitting something it should not. Wrong needle size, wrong presser foot for the stitch width, or a bent needle hitting the plate are common causes.
Affected Models
- Janome MC9900
- Janome MC6700P
- Janome Skyline S5
- Janome 4120QDC
- Most Janome machines
Common Causes
- Wrong presser foot for wide stitches — needle hits the foot
- Needle bent from hitting a pin
- Needle too thin for heavy fabric
- Fabric being pulled instead of feeding naturally
- Needle not fully inserted in the clamp
- Needle plate damaged with a burr catching the needle
How to Fix It
-
Use the correct presser foot for the stitch.
Wide stitches (zigzag, decorative) need a wide foot. A narrow foot with a wide stitch = needle strikes the foot and breaks.
-
Use the correct needle size for the fabric.
Thin needle + heavy fabric = needle bends and breaks. Use 14/90 or 16/100 for denim, canvas, and multiple layers.
-
Do NOT pull the fabric — let the feed dogs move it.
Pulling the fabric bends the needle sideways. Guide gently but let the machine feed.
-
Remove pins before they reach the needle.
Sewing over pins is the fastest way to break a needle. Remove pins as the presser foot approaches.
-
Check that the needle is pushed all the way up in the clamp.
A needle that is too low will hit the bobbin case or plate.
Frequently Asked Questions
Can sewing over pins break needles?
Absolutely yes. Even hitting one pin can snap a needle and send fragments flying. Always remove pins before they reach the presser foot.
Should I use a thicker needle for everything?
No. A thick needle on thin fabric makes large holes and puckers the fabric. Match needle size to fabric weight.
