Hello Yasmin,
Topo tension usually about 4 or 5, make sure the thread has gone completely between the tension discs, rethread the machine to be sure, make sure you have the bobbin in the corect way round and make sure you can only pull the thread through with slight resistence, if it is too tight slacken the screw on the bobbin case about a quarter of a turn anti clockwise and test.
