Hi, I have run into this problem on newer light weight machines. Remove the nose cover and look for thread wrap in the upper tension control, even a small piece of fluff can keep the discs from closing when you drop the presser foot. Try not to disassemble the upper tension control because they can be tricky to get back together. Check around the slack arm, thread will wrap-up at the pivot. Good luck.

Do you have a manual?

Looking at diagrams in the manual, I think you have to remove the accessories case to gain access to the feed dog control.
Hope this helps!

there should be a small set screw under the cover where you feed the bottom bobbin at. if you turn it right, it will tighten, and should raise it.just remember how many times you have turned the screw.

I had a singer machine that had a basting stitch that was like that. Make sure that you have chosen regular straight stitch.

Knots underneath means the top tension is too loose. Also grasp the threads when you begin a seam.

It is a problem in your top threading, you may have tangled thread, or need a new needle. Try this test when you have rethreaded with the presser foot up, pull thread, it should feed smoothly, now lower presser foot, pull thread, it should barely move. This will seat your thread in the tension discs and hopefully you will have no more problems
