The most common source of noise in sewing machines is the bobbin winder, which is responsible for winding the bobbin thread (e.g., during sewing). The bobbin winder is located on the sewing machine and is responsible for winding and unwinding the thread. The bobbin winder often makes a knocking sound when the bobbin thread is being wound.

Another noise that sewing machines make is the latch. The latch is located on the sewing machine and opens and closes the sewing machine. The latch is used to move the spool of thread in and out of the sewing machine.

Another common noise that sewing machines make is the thread tension, which is used to pull the thread down to the correct length. The thread tension is operated by the bobbin thread and is used to set the stitch length. A sewing machine makes a clicking sound when the thread tension is being adjusted.

How to Inspect the Sewing Machine for Noises

To do this, you have to open the needle plate and remove the needle. Once you do this, use a paper towel to wipe off any excess thread from the needle. Then, use some oil to lubricate the needle.

After lubricating the needle, put the thread back on the needle, replace the needle plate, and turn on the sewing machine again. You need to repair the machine if the sewing machine is still producing noise.

Cleaning a Sewing Machine can Prevent from Making Knocking Noise

Sewing machines usually last for years. However, there are things you can do to keep your machine in good shape.

Here’s how to clean a sewing machine:

  1. Clean the outside of the machine: This can be as simple as wiping all dust and dirt off the outside of the sewing machine. Use a soft, clean cloth to remove any accumulated dust.
  2. Clean the bobbin case: The bobbin case collects dirt and debris over time. Use a damp cloth to wipe away all the collected dust and lint.
  3. Clean the bobbin: The bobbin is another component that collects dust and lint. Remove it and wash it clean. Make sure to remove any thread fragments from the bobbin case. 
  4. Clean the sewing machine head: The sewing machine head is the machine’s most complex and sensitive part. This part should be cleaned only by a trained professional.

How to Lubricate the Sewing Machine?

If the sewing machine is making a knocking noise, first check and see if the bobbin is correctly inserted. The bobbin must be inserted correctly for it to spin properly. If it is inserted incorrectly, it may cause more problems than unnoticed. If the bobbin is inserted correctly, check to see if the bobbin thread is tangled.

Remove the bobbin case and carefully remove the bobbin thread. If the bobbin thread is tangled, untangle it carefully. Sometimes, the thread can tangle when it is removed. Using an old toothbrush can untangle thread without damaging it.

If the bobbin thread is not tangled, turn the sewing machine’s handwheel backward. If the noise disappears, then the bobbin case may be worn. It should be replaced.

Frequently Asked Questions

Why Does My Sewing Machine Make a Clunking Noise?

If the needle has not got a sharp point or if it is not correctly threaded, then it will make a loud clunking sound when you sew.

How Do I Fix the Clucking Noise on My Sewing Machine?

The noise could come from a broken stitch plate, a torn needle plate, or a worn needle ribbon. The best solution is to replace the sewing part, but doing this yourself may be challenging. It’s best to take your machine to a professional who has expertise in sewing machines.

Why Is My Sewing Machine Making a Squeaking Noise?

If the machine is making a continuous sound, it probably means that there’s a problem with the needle or bobbin case. You’ll need to take it to a repairman, because it may hurt the machine’s internal parts if they aren’t working properly. If the sound is intermittent, it may be a problem with the tension. Sometimes the machine needs a tune-up.

What Is the Most Common Problem for a Sewing Machine?

The most common problem for a sewing machine is a broken needle plate. When the plate breaks, the needle moves slightly out of place. This causes the feed dogs to move slightly, and the machine begins to feed the wrong stitch. To correct the problem, take out the needle and plate.

Thread the needle through the eye with a crochet hook and put it back in the needle plate, with the eye pointing down. Thread the bobbin case and put in the bobbin with the needle down. Put the bobbin case back in its place. Rethread the machine, and voila! You have fixed your broken needle plate.
