The bobbin thread isn't being taken

First I would check to make sure your needle is in correctly. Almost all modern sewing machines need the flat part of the top of the needle (the shank) facing the back of the machine. Them thread the needle front to back. Next I would check the upper thread tension. You can do this by threading the machine, setting the presser foot down and try pulling on the thread before it goes into the eye of the needle. It should be tight. Whet the presser foot is up, it should be loose. That will indicate if it is threaded correctly. After that, check the take up lever to make sure the thread is in it. Then I would have the timing checked.

You state that the bobbin thread is not being picked up by the needle, have you had one or two jams whilst sewing if so then I'm 99% sure you have knocked the cotton pick up hook out of timing potion, the shuttle bobbin sits in the hook case and as the hook rotates in the correct rotation the needle is at it's lowest point and at the same time the pick up hook should just about to go behind the needle as it starts to rise and it's at this point on the way up that the bobbin thread is being picked up, so if the timing as been knocked out of potion it as to be rotate with a little force whilst holding the and wheel and the needle in it's lowest position so that the hook is just and only just going behind the needle and that's it give it a run, normally I would say slacken the clamp screws that secure the hook assembly onto it's shaft, but you can usually get away without doing this it saves time and hassle. Hope you can understand what I have put down as instructions for resetting the hook if it's the case of being out of position.
Happy Sewing
