20 Most Recent Brother PE-770 Embroidery Machine Questions & Answers

Question edited for full maker, model (what it is)'. Question moved from Computers and Internet to model category. This doesn't appear to be documented. Normally I can find anything like this because it has happened to others. https://www.google.com/search?q=pe-770+doesn%27t+tie+knot ..

I would say it time to have the computer or sensors of the machine checked

Brand new? Take it back where you bought it. It is a defective unit.

THe noise that you heard was the fuse or a capacitor. Since this machine has an lcd display, it is most likely damaged to the point that it would be cheaper to replace it.

It is very important to have the bobbin case and the top tension both right. If the thread is getting stuck there is a problem. Always thread the top with the foot up. While threading make small pulls to make sure there isn't any places getting jammed. I've attached a rule document to help you to adjust the tension of the top and bottom.

Here is what I found Hope it helps. I didn't download anything, I just clicked on the pages and scrolled down.

Before using the needle, place the flat side of the needle on a flat surface and check that the distance between the needle and the flat surface is even. aFlat side bNeedle type marking ?Correct needle aFlat surface ?Incorrect needle If the distance between the needle and the flat surface is not even, the needle is bent. Do not use a bent needle. aFlat surface Replacing the needle Replace the needle as described below. Use the screwdriver and a needle that has been determined to be straight according to the instructions in "Checking the needle" . a Raise the needle by turning the handwheel toward you (counterclockwise) so that the mark on the wheel points up. (With models equipped with (needle position button), raise the needle by pressing once or twice.) b Turn off the sewing machine. c Lower the presser foot lever. aPresser foot lever

I used this machine in my middle school classroom. That message was in the first start up of the machine, I think it just resets the machine. The larger model also has a beginning reset button that just adjusts the arm of the machine. Is the machine working fine after the reset? Hopefully "sew"

Sounds like something in the machine in the head that makes it go up and down. either wear or something loose. I would have it checked by a Brothers repair shop

Usually this is a tension problem. On mechanical machines, you'd adjust the dial, or possibly even the bobbin tension. But on a computer machine, I don't know how you set the upper tension, sorry to say. Sometimes it can help to unthread and rethread a machine, and I don't know why it sometimes works, but it's a simple thing to try. But if the upper tension isn't set correctly for the work being done or if the tension mechanism, however that's handled on a computer machine, isn't working correctly, this is what happens. Bird's nest is a good way to describe it. Sometimes lint built up in the bobbin case can cause this symptom too, but I'd assume you keep this area clean. One reason I haven't yet invested in a computer machine is because problems like this often don't have such simple solutions as on the mechanical machines.

Oil? Maybe needs oil on that part of the machine.

It is done via the control panel settings. Look at the manual, page 21 and 22. http://www.brother-usa.com/VirData/Content/en-US/HAD/Consumer/UsersManual/UM_PE_770%20%20%E2%80%93%20New!_EN_1819.PDF

I think you should consider a little oil if it's metal parts - it is a small spring that holds the needle in place

Loosen the top tension a little or tighten the bobbin tension ever so slightly. If that fails you can always color the bobbin threads with a magic marker the same color as the embroidery thread. You might go to Superior Thread's web site and try some prewound bobbins. They are worth their weight in gold. Dr. Bob knows all about all kinds of thread and is very good about answering questions. I think some of his Thread University videos are available too.
