Machine stopping Every time I start the machine sewing it does 5 or 6 stitches ,and then stops with the message " thread breakage detected " I have changed the bobbin ,even put a new bobbin case in ,but nothing helps. Hope someone can tell me how to fix it. Thanks

Sounds like possibly more than one problem.

Sewing Machine Problem 1 Thread Breakage

If the top thread is not picking up the bobbin thread, it's possible the machine has been knocked out of time. Did the needle hit something or break recently? You can search for sewing machine timing or take it for service.

Remove the thread and rethread. Usually, thread breakage occurs when the thread is not following the thread path. However, there could be other reasons:

E7 means
The start/stop button, reverse/reinforcement stitch button
or the thread cutter button was pressed while no thread
cassette was installed. If the start/stop button is pressed before the sewing machine is correctly set up or if an operation is performed
incorrectly, an error message appears in the stitch indicator. Follow the instructions that appear.
If you press (Stitch selection key) or do the operation correctly while the error message is displayed, the
message disappears

What happens when it stops? Do you get an error message? Does it say that it's out of thread? Are you doing embroidery, or sewing at the time?

I used can air and blew out the reverse button area. Worked immediately after turning off and back on.

Hi....I also kept getting the check and rethread upper thread message, I\'d sew about 15 stitches and it\'d stop. Here\'s what I did. On the left of the machine, in the back there is a screw....loosen that screw, take cover off, then lift straigt up and out on the cover that has the 3 on it in your threading seqence. Next, I started inspecting and cleaning the thread route from top to bottom. Lo and behold....I get to the place where you come down the front of the machine and turn to go back up and I spot a little slit in the plastic piece so, when I was threading the machine I guess I was pulling it to far to the left causing it to wear a little slit in that piece....so, I finished cutting it off with a utility knife, used an emery board to smooth it down, put the covers back on and it works GREAT!!!! Who would\'ve ever that it\'d be so easy and save me a bunch of money!!! I sure hope this helps someone.

I have this problem when the thread isn't locked into position under the clear plastic guide on top of the machine. You have to hear it click 2 times on the right hand side. You have to pull the tread kinda hard. Hope this helps.

Check the sensor at the top of the machine. It is where the thread passes through the plastic "u-turn". Check to see if the wheel turns when you pull the thread through the machine. The wheel has a red marking on it. If the wheel isn't turning when you pull the thread, it may not be sensing the threading correctly.

I hope this helps. God bless you!

I had the same problem and one day my 9 year old said Mommy the thread is winding and cathing. I noticed that if the thread is not close to the silver metal arm it coils and makes a knot around the silver feed arm and also sometimes it cathces the little white plastic peace where the silver feed arm is connected to the machine.
