For most home sewing machines, manufacturers recommend regular maintenance to keep them running smoothly:
Every 1 year if you sew a few times a week.
Every 18–24 months if your machine is only lightly used.
Every 6 months if you sew daily, or use your machine heavily for quilting or embroidery.
Why it matters: Regular professional servicing helps prevent costly breakdowns, keeps tension balanced, and ensures smooth fabric feeding. Even if you clean lint at home, dust and thread still build up inside the machine where you can’t reach.
