How to Repair the Bobbin on a Sewing Machine
Sewing machines are a great tool to have around the house. From fixing a trouser hem to creating fun, festive holiday décor, there is much that can be done. Most sewing machines will last for years, but these machines do need regular cleaning and care. If you notice the bottom stitches are slipping or knotting you must repair the bobbin. On a sewing machine this can be done at home. Most of the time a bobbin causing threads to break or knot is simply dusty and in need of a thorough cleaning.

1
Unplug the sewing machine from the outlet and raise the presser foot and needle. This will prevent any accidental electrical problems.

Using the small screwdriver loosen the presser foot screw. This will also allow the needle clamp to be raised and loosened. Once these are loose, remove both the presser foot and the needle.

Tips & Warnings
Removing the presser foot and needle will give you plenty of room to work with the bobbin and case.
Use the small screwdriver which came with your machine.
If after cleaning the bobbin the thread continues to break, you need to adjust the upper thread tension.
Never attempt repairs on a sewing machine if it is plugged into an electrical outlet.
Never use water or oil in the bobbin casing. This can gum up the area and may put oil stains on future sewing projects.
