If your machine creates noises, it means that lint or oil are collected on the hook or needle bar. To fix this, simply clean the hook and feed dog as described in the instruction manual of your machine model. You can also oil the machine to make it operate smoothly.
Cleaning the feed dog can prevent the sewing machine from producing noises.
Moreover, a noisy machine could also be a sign of needle damage, so check the needle for any damage and replace if needed.
If the needle is blunt, bent or shows any other sign of damage, replace it with a new one.
