Bottom thead My bottom theard will not come up

indicates that the needle thread tension is not tight enough
disregard the tension settings
threead the machine correctly and before putting the thead in the eye of the needle pull on the thread
I foyu do not feel significant resistance to pulling the thread , thne check that the thread is between the tension plates or increase the setting up until you get that resistance , then thread the needle

This should seat the thread in the tension discs. Also, check that your needle is inserted right, flat side facing the rear of the machine. Good luck

change the needle
clean under the needle plate where the feed dogs for lint
clean the bobbin area for lint or loose threads
rethread the machine--make sure to get every thread guide

What is wrong is that you haven't got it threaded right on top. Try this test, with your presser foot up, pull on your top thead and it should come smoothly, then put the presser foot down and try it. it should hardly move. That way you know that the tension discs are connecting with the thread. Whenever it is not right on the bottom, always look at the top threading, just the opposite of what you think. Also, put in a new needle and make sure that you thread is of good quality and not tangled.

Before changing the tension settings, be sure to thead the machine with the presser foot up as this also has a tremendous effect on the tension and formation of the stitch.

It could be that you threaded the machine with presser foot down.

When the foot is down, then tension control is closed and the thread cannot seat for proper control to the needle.

What appears to be a bobbin problem is actually the top thread not having the tension needed (thead is not where it should be within the tension control) to form a stitch.

If you thread the machine with the presser foot up, the stitching should be okay.

Zero for straight stitch and anything more is zig-zag.

Try threading the machine with the presser foot up.

This opens the tension and allows the thread to seat into the tension control.

When the thread is not properly seated, there isn't any tension on the top thread the bobbin thread cannot make a proper stitch with a top thead that is loosey-goosey.

Always thread a sewing machine with the presser foot up - this will make sure the tension feature has control of the top thead.

Make sure the needle is properly placed - usually with the flat side toward the back of the machine.

The tension used to wind the bobbin is not wright, remove all the thread and rewind the bobbin. Make sure that you put the bobbin in place exactly as shown on the image, I didn't in the beginning and couldnt figure it out, now I now IT IS VERY IMPORTANT TO PLACE THE BOBBIN CORRECTLY.
