How to Find the Brother SE400’s Machine Number

Using embroidery designs from Brother’s site requires that the design be linked to the machine that you’ll use to embroider the design. This allows Brother to prepare the size and format of the design that will work properly with your machine. It also allows them to copy-protect the designs, especially the special licensed character designs.

The machine ID is used to connect the machine to the design. The machine ID is unique to your machine and is different than the machine serial number.

The machine ID for the Brother SE400 is found in a Settings page using the Control panel. Press the Settings Key on the Control Panel (circled in red in the photo below):

Select the Settings Screens

You’ll come to the first page of settings. Press the > key until you get to the page with the machine number on it.

Select the Settings Screens

    I purchased this machine at an estate sale…it appears to have everything except the presser feet or the accessory kit. Thea Machine appears to be almost new with the instruction CD and book in good shape. Where can I order the feet or an accessory kit? I can’t wait to try it out!!!!
    Thank you so much.

    I have done quite a few Monograms with my SE400 and they never seem to come out perfect. Thread on top always seems looser or bunched in some spots. What am I doing wrong? Could it be the thread? Backing? Material? Please help, as I am very frustrated and keep ruining clothes.

    • Kamala says

      Hi Emma, Unfortunately, many things can cause that including all the things you mentioned. First I would stop ruining clothes. Get some easy, test fabric (like a medium weight, woven, cotton or blend – not knit) and medium weight stabilizer. Practice on that until you get it right. Then clean the bobbin area, following the instructions on p. 152 in the Operations Manual. Pressure Foot up. Remove the top thread from the needle, cut it at the top before the spool and pull it out from the bottom. Make sure you’re using embroidery bobbin thread 60-wt. (a spool and some pre-wound bobbins came with the machine). I’ve never had a problem with bobbins, but some people have if it’s not wound tightly or evenly. I’ve never had the brand of thread make a difference except for some rough burrs on the spools that caught the thread. Then, rethread the top and bottom, making sure the bobbin and case are installed correctly and the thread is in all the tension disks (always have the pressure foot up). With the pressure foot down, you should feel a resistance when you pull on the thread. Test the tension following the instructions on p. 145 in the Manual. There is a list of causes and remedies on page 158 in the Manual (section on Embroidery not neatly done.)

      After you like the results using the tests, get some material similar to your clothes and test again. Knits are more difficult because of the stretching. They need more support–I use medium weight cutaway stabilizer. I have found tear away, not to work as well. And if the embroidery is sinking down in the fabric, I float some water soluble stabilizer on top (not hooped). has a series of articles on techniques for different fabrics that you may find helpful.

    Hello, my se400 started making a squeaking noise yesterday while embroidering. I checked my manual, it said could be dust buildup, or burr on bobbin case. I cleaned but it is still squeaking. I was wondering if anyone else has had this happen?

    Also I was wondering how often it should be serviced.

    Any help would be appreciated.

    Have a Brother SE400. Trying to learn to do appliques. I cannot find a stitch that is wide enough to outline with. Can anyone help?

    I have two questions.
    q.1 does my machine need to be added to the devices on my laptop for example, like a printer , I went to this place on my laptop and was unable to add my sewing machine.
    q.2 I know the format for downloads format. But what program should they be downloaded in such as for example Adobe acrobat or Microsoft Word or Media Center. some of my designs have been accidentally changed to a defult Media center program. When I click on them it brings up the Media Center, I think that I need to change that but do not know how or what to change it too.

    I just recently bought this machine as well, but haven’t downloaded a design. Once i download and pay for the designs, am i able to use it as much as I want? And do I need a memory card for this machine? Or do I just connect the my machine and it saves there?

    Thank you !

    • Kamala says

      Hi Lisa,
      All the designs I have downloaded let me use them as much as I want and sell items with the design on them. You can’t sell the design itself. But it depends on the license of each designer, so you need to check there. You can use memory cards, but I just connect the SE400 to my laptop and copy them over using the included USB cable. I wrote a detailed tutorial that might help you with it: Click here.
      Happy embroidering!

  8. Claire McCann says

    I’ve bought my SE-400 machine and am really loving the way it works. I have a problem and don’t know what to do. As I was taking off the bobbin after loading it with thread, somehow the little pin that fits into the peg came off at the same time and there is no telling where it went. Do I have to take the whole machine in to have this replaced or is there somewhere that I might be able to find one?
    Thank you,

    I recently stitched a design from atw website. The machine did not stop after the second color and part of the design stitched in the wrong color(if I was really paying attention I could have stopped and loaded the right color). I have heard that occasionally some Brother machines don’t recognize a color change(if the colors are similar) and I should change one of the color numbers (on the screen) and just load the original color when stitching stops. Anyone else encounter this?

    • Kamala says

      Hi Sandra,
      That’s interesting. I’ve never had the SE400 not recognize a color change, but maybe my colors haven’t been similar enough. I think it would be very difficult to tell if the colors are similar because it doesn’t even really know what the colors are anyway. My designs are created with numbers from one brand of thread. I use another brand. The SE400 doesn’t have these brands in the settings and just comes up with very different colors. I ignore what it says and just load up the thread I want. Also, I don’t know of any way to change the color numbers from the screen. Maybe it’s a problem with the high-end models with cameras that really do know what color the thread is. I always run through the “Check Colors” key on the screen just to check. Sorry, this isn’t much help. I wonder if it’s a problem in the design. If you have embroidery editing software, you could open it up and check.

    Thank you so much for your fast response! I never would have thought of looking there! This is my first machine, so i’m a little new at it. So far I love the machine. I have embroidered on organza and with metallic thread and have had no problems as of yet. So as of now I am a very happy camper. Now even more so having that number! Thanks again! Keep up the good work! I do love your site!
    Best regards
