When your passion is dressmaking and designing, the sewing machine is your ultimate best friend. It is the one that guides your cloth, career, and seam strips, thus, an essential part of your life. 

Today, we will look at some problems your best friend might cause and learn to repair sewing machines like a pro. Don’t worry; it is going to take a little effort and easy steps to reach the goal.

First of all, you should look at the manual provided by your sewing machine shop. If you are using an antique machine, then the manual can easily be found online. 

If the solution to your problem is not in the manual, then try looking up the machine model and structure to study it from a better perspective. Still, most machine mechanics are the same, so let’s get started with basic problems and their solutions.

Problem: Uneven Seams and Rough Stitching

Answer: This usually happens when you don’t give attention to your machinery, and small lint gets clogged in. So, all you need is an old toothbrush and a screwdriver (if required). 

Unscrew the Throat plate, remove the Bobbin case, and dive right in with the driver to keep those holes clean. 

Stuck or clogged lint can produce noise and uneven seams. When you are done cleaning the machine thoroughly, make sure to tighten every screw. You are done with sewing machine repair so get back to stitching.

Answer: It is the most common problem for tailors and DIY lovers, but don’t worry because the solution is easier than you think. Firstly, make sure that the thread of Bobbin and upper thread are the same because the difference in weight can cause clogging.

When you know this is not the reason for your issue, then re-thread your machine by putting the presser foot to rest. Re-thread, the upper body, double-check for all the right turns and hooks, and then re-thread the Bobbin and Bobbin case accurately. Wasn’t it easy than expected? Yup, we thought the same. Happy stitching! 

Problem: Constant Breaking of Threads

Answer: If your thread breaks, make sure the upper and bottom threads are the same; if yes, then re-thread your upper machine and set the tension with the Tension Regulator presented on top of the machinery. 

Most threads break due to uneven pressure and the weight ratio of fabric. Also, make sure you use the thread compatible with sewing machines, and they are not as delicate as used in hand stitches. 

 These were some of the basic issues a person faces, but we sprint an extra mile to accommodate more and answer your queries.

How often does my sewing machine require services? 

Frequent service depends on the usage of sewing time; ideally, you should clean your machine thoroughly after sixteen sewing hours.
