Why is my bobbin thread is showing while embroidering

Yes just lower your upper tension until the white disappears.

I have a 600 also...have you changed brand of white thread? Sometimes it can be the design you are embroidering that will bring bobbin thread to the top. I use the prewound bobbins--very thin thread & tightly wound.

With the embroidering, some of the bobbin thread is SUPPOSED to show on the top of your embroidery-the machine isn't doing anything incorrectly. You'll need to thread your bobbin with the same thread as you are using with the top. I had the same "problem" when I first got the machine and took it to a wonderful local technician whose helped me with a lot of things who informed me that this is perfectly normal on embroidery machines.

Make sure to use bobbin thread for machine embroidery, it is heavier and pulls the top thread slightly to the back of the design.

You could loosen the tension or use a double layer of stabilizer.

the problem of your machine is, under the plate of your machine, you saw the teeth look like the used of it is to move forward the cloth u embroiderd, you should tight the bolt or nuts so that, the bunching up of thread on the plate will stop. thank you!!!!!

Try making the material tighter in the hoop and check your bobbin to be sure it's a L (look at your instruction manual...it will show you which bobbin works and which does not. I say this because you have a tension problem...dont we all, Ha Ha!

Hi, and welcome to FixYa. If I understand your problem, the needle goes in and out of your fabric, and the embroidery hoop moves, but the machine does not actually start embroidering your design right away....did I get it right? If have time to answer a few questions, I can give more accurate instructions.

1. How long have you had your machine?
2. How long have you been doing machine embroidery?
3. Do you have a manual for your machine?
4. Look at the back side of your design - do you see lots of bobbin thread, or hardly any?
5. Have you taken lessons for your machine or for embroidery?
6. When your design is finished, can you where the machine skipped stitches?
   

Here a couple of things you can try (if you have already):

• Make sure you use an embroidery needle, not a universal. In most cases, you should use a size 90. Change your needle after each project. A blunt need can cause your machine to skip embroidery stitches anywhere in the design.
  
• Rewind or replace your bobbin. Make sure you use bobbin thread in your bobbin when you embroider - it is thinner and gives you better tension. If pre-wound embroidery bobbins are compatible with your machine, I recommend that you try one and compare the result with designs sewn using the bobbin thread you've been using.
  
• Normally, you should loosen your tension a little bit when you embroider. When you look at the back side of your embroidery, you should see more bobbin thread than embroidery thread.

I owned an embroidery business for several years, and I have six different embroidery machines of my own - so with a little more info from you, I think I can help.

Check for loose threads or fluff in upper tension unit and bobbin case tension gauged to 14g resistence. Otherwise, service time I'm afraid. Have it serviced by an authorized Husqvarna Viking Service Technician. You can locate a dealer near you by visiting the husqvarna viking website and clicking on the Dealer link on the left-hand side of the page - http://www.husqvarnaviking.com

Good luck.

Hi,

You don't have much info here to go on. I take it that it embroiders fine otherwise, ie on the built in designs. Is it a Janome card? Does it do it on a particular card / design? Have you changed the bobbin thread that you use? Check the top tension - even though it is 'automatic', it does require adjustment at times. Have you changed / using stabiliser that you use? Is the bobbin correctly threaded?

Check these things

I have had the same problem. I always just used the same color of bobbin thread as on the top. It is a pain to change inbetween each block, but the designs usually look perfect. I will have to try playing with the tension.
