When a sewing machine stops feeding fabric, the feed dogs, the toothed bars under the presser foot, are usually either lowered or unable to grip. Check that the feed dogs are raised (the drop-feed lever or slider is often at the back of the free arm or beside the bobbin), that the presser foot is down, and that the stitch length is not set to 0. Those three settings explain most cases; the rest come down to lint packed under the needle plate, too little presser-foot pressure, a foot that cannot grip the fabric, or a thickness the foot cannot climb.
How does a sewing machine feed fabric?
The feed dogs move in a small loop: they rise through the slots in the needle plate, move backward by the stitch length, drop below the plate and return forward. The presser foot presses the fabric down onto them, so each rise carries the fabric back one stitch. Nothing else moves the fabric; your hands only guide it.
So feeding stops when any link in that chain breaks: the feed dogs are below the plate, the foot is not pressing, the distance they travel is zero, their teeth are clogged or worn, or the fabric is too slippery, too sticky or too thick to be gripped.
Symptom, cause and fix at a glance
| What you see | Most likely cause | Fix |
|---|---|---|
| Needle stitches in one spot, fabric does not move, no resistance when you push it | Feed dogs dropped | Raise them with the lever, then turn the handwheel one full turn |
| Stitches are tiny and the fabric creeps or slides sideways | Stitch length at 0 or near 0 | Set 2.5 mm (10 stitches per inch) |
| Stitches form but the fabric barely moves | Presser foot up, or foot pressure too low | Lower the foot; increase the pressure |
| Feeds fine until a thick seam, then stalls | Foot tipped up on the step | Level the foot with a hump jumper or folded card; walking foot |
| Vinyl, laminated cotton or leather stalls under the foot | Foot sticking to the surface | Teflon, roller or walking foot; tissue paper on top |
| Fine fabric is pushed into the needle hole instead of moving | Needle hole too wide, pressure wrong | Straight-stitch plate and foot, start on a scrap |
| Feeds badly on every fabric and has got worse over months | Lint under the plate, worn teeth | Clean; have the feed dogs checked at a service |
| Only with the darning, embroidery or free-motion foot | Feed dogs are meant to be down for that foot | Fit a standard foot and raise the feed dogs |
How do you diagnose a machine that will not feed, step by step?
- Raise the feed dogs. Machines drop them for free-motion quilting, darning and sewing on buttons. The control is a lever or slider at the back of the free arm, a switch near the bobbin cover, or on some older machines a cover plate that snaps over the teeth. Set it to the raised or feeding position (often a row of teeth icon), then turn the handwheel toward you one full turn: on many machines the feed dogs do not come up until the mechanism has completed a cycle. Watch them through the slots as the wheel turns.
- Lower the presser foot and check its pressure. With the foot up, the fabric lies on the teeth without being pressed into them and does not move. Many computerized machines also refuse to sew with the foot raised. Then look for the pressure control: a dial or screw on top of the machine at the left, or a setting in the menu. Light fabrics need more pressure to feed evenly; thick or stretchy fabrics need less so they are not pushed ahead of the foot. If you have ever turned it right down for a knit or a pile fabric, set it back to the middle.
- Set a stitch length. A length of 0 is used for bar tacks and buttons, and some computerized machines return to it after certain stitches. Set 2.5 mm for general sewing, 2 mm for fine fabric and 3 to 3.5 mm for topstitching and heavy fabric; the stitch length entry explains what each length suits.
- Deal with thick seams. Where a hem crosses a flat-felled seam on denim there can be eight or more layers, and the front of the foot tilts upward on the step like a car bumper against a kerb. Tilted, it cannot press the fabric onto the teeth. Stop with the needle down just before the seam, raise the foot, and slide a folded piece of card or a hump jumper under the heel so the foot sits level, then sew over the step slowly by hand-cranking a few stitches. A walking foot with its own set of feed teeth also helps on bulky, layered seams.
- Change the foot for sticky or slippery surfaces. Coated fabrics, vinyl and leather grip the sole of a metal foot and do not slide. A Teflon or roller foot, a walking foot, or a strip of tissue paper between the fabric and the foot gets them moving. Sewing machine presser feet explained goes through what each foot does.
- Clean under the needle plate. Lint from fleece, flannel and toweling packs between the feed dogs until the teeth barely rise above it. Unplug the machine, remove the needle plate, brush and pick the lint out, and look at the teeth. On a machine that has sewn for decades the teeth can be worn smooth, especially in the middle rows; that is a service item. How to clean and oil a sewing machine covers the rest of the routine.
- Check your own hands. Pulling the fabric from behind or holding it back in front lifts it off the teeth, and a heavy garment hanging off the table drags against the feed. Let the fabric lie flat, support its weight on the table or your lap, and guide rather than push. If you find yourself tugging to make the machine feed, something above is still wrong.
What if the fabric feeds, but unevenly?
Fabric that feeds in fits and starts, or where the top layer ends up longer than the bottom, points to the presser foot rather than the feed dogs. The foot holds the top layer back while the teeth carry the bottom layer forward. Reduce the foot pressure a little, pin across the seam at 5 cm (2 in) intervals, and use a walking foot for long seams in slippery, stretchy or napped fabric. Sewing knit fabrics on a regular machine explains the settings that stop knits from stretching under the foot.
Tip: When your pattern instructions do not say which foot a step needs, ask. The sewing guide that comes with each Sewly pattern answers questions about your own project, such as which foot and stitch length to use for a bulky waistband seam.
When is a machine that will not feed a repair job?
If the feed dogs do not rise at all with the lever in the feeding position and the handwheel turned, a linkage or a plastic gear inside has probably failed, which is common on machines that have sat unused for years. A feed that has grown weaker over months despite cleaning suggests worn teeth or a worn feed cam. Both belong with a technician; the cost is usually modest on a machine worth keeping.
