Thread looping under your fabric is usually caused by not threading the upper tension correctly.
With the presser foot lever in the UP position and tension set at 4, follow the threading guides/graphics on the top of the machine.
Place the thread spool on the spool pin and secure with a thread spool cap.
While holding the thread with your right hand, use your left hand to take the thread down into the tension channel around the bottom and up the other side. As the thread comes up the opposite channel, and reaches the top, you will need to slip the thread from back to front into the take up lever. Continue to thread the machine, but do not thread the needle.
PRO TIP: Before threading the needle, perform this easy test to make sure the upper thread is threaded correctly. Making sure the presser foot is raised, pull the thread. It should pull easily. Now lower the presser foot, the thread should now resist when you pull it. There should be a significant increase in the tension of the thread. If there is no increased tension, the machine is not threaded correctly.
