Turn off the Thread Sensor. You may have to do this each time there is a thread change. :-) 24 Feb.2014

    I heard the story wrong from my wife. We had our machine repairman disconnect it.

These machines typically have threading issues. In the thread path, there is a sensor that reads the thread. It quite often gets lint and pieces of thread. Where the thread goes through the thread path on the upper read is usually the culprit. Take off the plastic cover where the thread goes from rear towards front...look for the metal plates and carefully clean between them. You also need to make sure that thread goes all the way to the inside of these discs. I try to always pull the thread from spool and thread end to make sure it gets properly seated.

The thread keeps bursting after a few stitches. I've tried adjusting upper & bottom tensions,changing the needle, trying it with different fabrics, but nothing seems to work. What do I do?

Usually when it stitches an inch or two and then breaks, the upper thread is mis-threaded.

Remove the upper thread and rethread from the beginning. ALWAYS RAISE the presser foot when threading the upper thread. Check to make sure the thread path is correct. If it is threaded incorrectly, the thread will frequently break.

Also check that the thread is not hanging up somewhere, sometimes it gets looped around something or it snags on the little slit on the thread spool or a rough spot.

If the upper thread tension is too tight, it will also break the thread. Make sure the tension disk is clean. If there is gunk or a piece of thread stuck in the tension disk, it could be interfering.

If the thread is fraying as it goes through the needle eye, then there is probably an incompatibility of the needle, thread, fabric.

Top thread keeps breaking

Upper thread breaking is usually a sign of incorrect threading or tension too tight, although there are other possible problems:

Industrial Garment Printers Sewing Machines

When threading the upper thread, be sure to ALWAYS RAISE the presser foot so the thread will seat properly in the tension disks. Avoid old thread or bargain bin thread. If the thread is fraying and breaking at or near the needle eye, then try a different type of needle with a larger thread groove that will protect the thread from fraying on rough fabric. Also, check that the thread is not hanging up on something, ie the slit on the side of the spool where the thread tail is stored.

The upper thread on my Euro-Pro 7535 keeps breaking.

Have you checked your tension for the thread and material? Is the same thread and in the bobbin too?
If you can tell where i t,is getting caught, does this not solve your problem? Is the plastic thread feeder, rough? you can use very fine emery paper to smooth it out. :-)

Keep getting check upper thread message

You have left threads in the thread path that you can't see or get to without a technical knowledge of the necessary "cleaning process"
Go and see your machine repair man who can show you how to get to the problems areas without messing up the mechanicals even more.

I have an Esante ESe2 and am having trouble with the upper thread breaking. I have checked bobbin case for fuzz and thread, re-wound the bobbin, re-threaded everything and nothing helps! Please help me...

Open the top part of the machine. My mom just bought one and it had lots of thread inthe thread path of the thread on top. You have to open up the area that the thread runs thru. It solved her problem of thread breaking. She found lots of thread inside.

I tried everything i have a Brother SE-400. For the last three months I haven't had any problems with the machine now, I am getting a "check and rethread the upper thread error". Nothing I do seems to...

Is your thread old? I had some thread that I was trying to use up and my machine decided that it did not like it all of a sudden. Maybe, unplug and totally rethread with a fresh needle. Sometimes, the little buggers get particular. Hope it is something this simple. Good luck

I have a brother 270D and the upper thread keeps breaking (common i know) but ive done everything int he trouble shooting section of the manual.. its only when i embroider too. checked different tensions,...

I had the same problem with my machine and what was causing the problem was the use of the wrong size bobbin. Check and make sure you are using the right size (type a) and if you can get bobbins already wound it would be better. Hope this will help you

Dear Wendy,

The E4, error message means the safety device is activated. Machine is locked up due to thread entangled with the bobbin case. Remove the needle plate and bobbin case. Check for any thread around the hook area. Also check your handwheel. It should turn freely. Good Luck
