Sounds as though you've misthreaded the upper tension. The best way to verify this would be to thread your machine, lower the presser foot on to the material. Now try pulling the thread through the needle. (Assuming your upper tension dial is set to a number greater than one). You should feel resistance. Should you not feel resistance, rethread your upper tension.

Pull the thread through the tension assembly and
test it to make sure the tension is working correctly.
(To do this test, adjust your tension setting to normal or medium or 5 or something in the middle. Raise the presser foot and pull the thread through the tension. It should pull easily!! Lower the presser foot and pull the thread. It should pull noticeably harder.) If it passes this test, continue up through the take up lever,then down through the thread guides to the needle.
If it passes this test you need to remove the bobbin case and check for burrs or rough spots. If you find any ,use an emery stick to remove them and then buff the area with fine steel wool.Put the bobbin case back in ,check your bobbin(change it ) and try again by turning the handwheel slowly and watching to see where thr thread is snagging

SOURCE: Problem with winding thread onto
first you must make sure the winder shaft is turning by moving it to the right a little and see if you can turn it by hand.
If it is turning ok then there is a rubber ring on the other end of the winder shaft and it should come in contact with the drive which turnes it ,if it is worn it might need a new rubber.

SOURCE: Bobbin problems
Any time you have looping on the bottom, it is almost always related to the upper tension and not anything in the bobbin area.
A good way to troubleshoot this is to turn the machine off, blow out the upper tension disk assemblies with canned air, (the machine needs to be off because most canned air uses butane as a propellant. Butane + electricity = bad;) replace your needle, and rethread your machine. Once you've threaded it to the point where you're about to put the thread through the needle, "floss" the thread forward and backward to ensure that the thread seats correctly into the tension assemblies.
Set your tension to around 4.5 for most applications, and drop your presser foot. Give the thread a gentle tug to see if the tensions have engaged the thread, then thread the needle.
If doing this does not address the problem, you probably need to have your tensions professionally calibrated. This is also true if the needle is in fact hitting something in the bobbin area. This is usually caused by the machine's timing being out of alignment, which is not something that can be fixed at home.
