Watch out for thread remnants

Check if there are thread remnants anywhere in the hook or the hook race. Be sure to check the hook, especially if there are tangled threads in the bobbin case area and/or the gears appear on the screen. You can find out how to remove tangled threads from inside the machine here.

First remove the bobbin case and the hook. The tutorial for your machine shows you how to do this.

Thread remnants can also get tangled on the two silver-colored hook driver cams. You can carefully remove these with tweezers. Please do not use any other sharp or pointed objects such as needles or scissors, as this could damage the hook race.

Use a microfiber cloth and brush

It is best to clean the hook, the hook race cover, the hook race and the bottom of the hook with a clean, dry microfiber cloth, as oil and lint create sticky residue that cannot be removed with a brush. Wipe the hook from the front and back with the microfiber cloth, and also the folded out ring-shaped black hook race cover.

However, a brush is better for cleaning under the stitch plate.

There are several methods for reinserting the hook. You can see an example here. It is important to position the hook correctly on the hook race ring: the left tip of the hook must line up with the left tip of the hook race ring. When the hook race ring is folded up, the hook is moved magnetically into the correct position and clicks into place.

Clean the thread catcher

Thread remnants or lint can result in the thread no longer being cut correctly or not being cut at all when the thread cutter is activated. This makes it all the more important to clean the thread catcher regularly.

First remove the presser foot, the needle and the stitch plate and lower the feed dog. Then go to Setup and select "Machine settings", "Maintenance/Update" and "Thread catcher cleaning".

A step-by-step guide appears, whereby it is important to always follow the order. For example, if the thread catcher is already extended but the needle has not yet been removed, it will be in the way. 

Do not use compressed air sprays!

Please do not use compressed air to clean your machine or the thread catcher as this can blow dirt into inaccessible areas of the machine that can only be removed by a technician.
A microfiber cloth and brush are sufficient.

Of course, you can also have the machine professionally cleaned by a specialist dealer. They will also clean areas that are not accessible to you.
