Pat Asii Designs Igor Take out bobbin and the thread plate Sounds like a Major cleaning is needed...thread dust buildup
Linda L Price Downey Try rethreading your machine all over again and then make sure your bobbin is clicked in right. I have had this problem before and had to do both all over again.Make sure to clean your machine also. Gets lint in the bottom. Somtimes my machine will pull the bobbin thread from the bottom to the top and I have to use a clear thread in the bobbin. Viking used to sell a clear thread and now they don't .You might be able to find it online,It is called Lingerie & Bobbin thread. It is made in the USA by YLI Corp, Rock Hills S.C. This clear thread works great for me. Use it on all embroidery except FSL Lace. Hope this helps you some.
Jan Foley-Harris Try changing the top tension , it might be pullin too much on your bottom thread .....
Angel Dodson This happened to me I had to have the machine cleaned and service to realign it. They said it is caused by using two different weights of thread in the machine. For instance cotton thread on top and nylon or polyester thread on bobbin. It throws the tensions out of alignment.
Jenny Taylor you might change the neddle it might have a bur on it
Lois Johnsen or try oiling it.. believe it or not sometimes thats all it needs... clean and a bit of oil
Jenice Allred New needle, clean all the lint out and oil. That usually fixes mine.
Mae SANDERS CHECK YOUR TENSON BOTTOM AND TOP
Karen Ceplina Hamski I have also experienced this and with the same fixes the others have listed...but also had it when i didnt use enough stablizer and the stitch density was too much for the size and complexity of the design. Barbara Sampaulesi Tension problems......have you done the bobbin test with your bobbin? Take the bobbin out of the machine.....leaving it threaded in the case - hold onto the thread and let it fall, sort of like a yo-yo....it should not fall all the way down.....also....make sure you don't have fuzz and things in your bobbin area where your thread pulls through?
Stacey Bible what are you sewing on? I've had the bobbin thread show on top when I was sewing on fleece and needed to put a layer of water solvy on top.
Kathy Samson This has happened here and all I did was clean out the bobbin case really good and put in a drop of oil added a new needle then it purrrred like a kitten with purrrrfect stitches. Good Luck Igor let us know how it goes! Dunia Van Rensburg McMaster and u can also loosen the top tension a bit ------- VERY IMPORTANT the bobbin area must be very clean at all times and oiled at least once a week OR more often if used in excess, sometimes if the bottom thread is coming to the top it not in teasion properly. I worked for a sewing maching company for a number of years!!!
