Have you hit a hoop while sewing? Is the needle jammed up and will not come down or down and will not go up? You need to make sure that you have no thread in the bobbin area. Even a tiny little piece will lock it up. Have you kept it oiled ? There are several places that need oiling. Bobbin area and needle bars are the two main ones. Make sure your needles are all the way up

check needle thread tension is tight enough

take it in to a sewing machine repair shop for a service

How can I fix this problem on the Necchi sewing


That bird's nest of a jam is very frustrating! Here are a few checks to make.
1. Ensure that the upper thread is threaded correctly, that is, that all the guides are engaged in the correct sequence.
2. Ensure that the upper thread is firmly settled between the tension discs and in the take-up lever.
3. Double check that he needle is inserted correctly.
4. Ensure that the bobbin is inserted correctly ... the thread is spooling off in the correct direction. This is very important.
5. Ensure that the bobbing thread is locked in the tension spring.
6. Make sure that the presser foot is in the down position as you begin stitching.

Machine Locked


Hi, First of all, make certain you remove both parts of the needle. Sometimes it breaks under the plate and knots up with the bobbin. If that is so, lift the presser foot and carefully try to lift the plate so you can get scissors under it to cut the thread and free the needle. Pull the bobbin out and replace it and put a new needle in. It should work fine.

Remove needle & reinsert needle( flat side towards the back of machine)
2. The needle is damaged
replace with new needle
3. The wrong size needle is being used
Choose a needle to suit the thread & fabric

I was sewing, turned the machine off to pin something, and when I turned it back on, it jammed in the bobbin area. It will only stitch one stitch and then jams. I have taken it apart over 30 times, and...


have you tried changing the needle-
1.the needle may be bent or damaged--try rolling the needle on a flat surface to see if it's bent or not
Correct needle insertion
Correct needle insertion is mandatory for proper use of sewing machine.
Raise the needle bar to the highest point, then loosen the clamp screw to remove the old needle, place the new needle in the clamp with the flat side to the back of the machine or if using a round needle--the groove in the needle should face away from the shaft.
Push the needle all the way up to the stop or as far as it will go, then tighten the needle clamp screw
2.upper tension may be to tight--try 3 to 5
3.thread may be hanging up in bobbin case--check area for loose threads or lint
???
check the thread take up lever-if the thread come off the thread take up lever that will jam the machine up--I've had it happen to me

I can start working withmy baby lock, the needle brokes verytime i runthe machine , and i can not sew


If this machine has a needle position adjustment and it is on the center position -

and you are sewing a zig-zag stitch and using a presser foot with a narrow opening this could break the needle

and the needle plate is a single hole, this will break the needle.

and you are sewing a straight stitch with a new needle and it breaks, the machine needs to go in for servicing.

Thread bunching and jamming in bobbin area


what you have is known as bird nesting and is from the needle tension not being tight enough
before you thread the needle pull the thread and the correct tension is when there is noticeable resistance to pulling the thread
always check adjustments using scrap material
