Do not sew again until every fragment is accounted for. A loose piece of hardened steel in the hook area will chip the hook or jam the mechanism, and a fragment left in the fabric ends up in a finished garment.
Account for the whole needle first. Lay out what you have found and compare it against a new needle of the same size. If the pieces do not add up to a complete needle, something is still missing.
Where fragments go, in order of likelihood. Into the bobbin area through the needle plate hole. Onto the machine bed and the floor. Into the fabric layers themselves. Under the presser foot. Occasionally they fly, which is why sewing without eye protection over very heavy work is a poor idea.
How to search. Remove the needle plate and the bobbin case and look with a torch — fragments sit in the race and in the feed dog slots. A small magnet passed over the machine bed, the fabric and the floor picks up what the eye misses. Shake the fabric out over a light surface.
Then clean properly before refitting anything, because a search that dislodges a fragment into the mechanism has made things worse.
Turn the handwheel by hand for a full rotation before running the motor. Any grinding or resistance means something is still in there.
Finally, work out why it broke. Pulling the fabric, a wrong needle for the weight, a hit pin, or a needle not pushed fully up into the clamp.
Questions people actually ask
I cannot find one piece.
Do not run the machine. Remove the plate, the bobbin case and the foot, and search with a torch and a magnet. If it is still missing, it is worth a technician looking.
Can a broken needle damage the hook?
Yes. A steel fragment caught between hook and race can score the hook, and a scored hook shreds thread afterwards. That is why the search comes before the next seam.
