Why Won't My Sewing Machine Sew in Reverse?

The reverse stitch is essential for securing seam ends and reinforcing stress points. When it stops working, it is annoying and can affect the durability of your finished projects. Here are six reasons your sewing machine may not sew in reverse and what to do about each one.

1. Your Machine May Not Have a Reverse Function

Not all sewing machines can sew in reverse. On vintage machines, there may be no dedicated backstitch lever at all.

The location of the reverse control varies by machine type:

• Older mechanical machines: The stitch length control doubles as the backstitch lever. Hold it upward while sewing to go in reverse.

• Newer mechanical machines: A separate backstitch lever, usually located toward the lower right of the machine.

• Computerized machines: A button you press and hold while sewing to reverse direction.

If you are unsure where your reverse control is, check your user manual.

2. The Backstitch Lever or Button Is Broken

The backstitch lever is durable but not indestructible. The internal spring can get bent or the lever itself can break, especially on older machines or after accidental impact.

A broken backstitch lever is not a straightforward DIY repair. Take the machine to a qualified sewing machine technician.

3. The Backstitch Mechanism Is Jammed

Thread or lint can work its way into the reverse-stitching mechanism and jam it. This is not common, but it does happen, particularly if a thread has broken loose and gotten inside the machine.

Open your machine's side panel and inspect the area around the backstitch lever. Clear out any visible thread, lint, or dust. Run the machine and test the reverse function again.

4. Automatic Lockstitch Mode Is Enabled

Many computerized machines offer automatic lockstitching as an alternative to backstitching. When this mode is active, the machine creates a tiny locking stitch at the beginning and end of each seam automatically. While this feature is useful, it typically disables the manual reverse function.

If you have accidentally selected the automatic lockstitch mode, switch back to a standard stitch setting. The reverse function should work again.

5. The Stitch Length Is Set Too Short

A very short stitch length can interfere with reverse stitching. If the stitch length is set to zero, the machine will not move the fabric in either direction. If it is set extremely short, the reverse function may appear stuck or ineffective.

Pin It

Check your stitch length setting and make sure it is between 2.0 and 4.0 for standard sewing. It is easy to bump the stitch length dial without noticing.

6. The Selected Stitch Does Not Support Reverse

Not every stitch type allows reverse sewing. Most overcasting stitches, many decorative stitches, and some zigzag variations are programmed to sew in one direction only. Attempting to reverse with these stitches selected will either do nothing or produce an error on computerized machines.

Switch to a standard straight stitch and test the reverse function. If it works, the issue was the stitch selection. Check your user manual to confirm which stitches on your specific machine support reverse sewing.
