Try re-threading your machine along with changing the bobbin. Could be many reasons this is happening. Changing the needle may help. I had a lot of problems when using a bent needle. Good luck & happy sewing! Also, YouTube has videos on threading your machine & solving common sewing problems, possibly even for your specific machine. Hadn't sewn in many yrs., I forgot how to thread my machine! YouTube had videos with my same machine, it was very helpful!
There is a possibility that the needle you are using is not meant for the machine. Alternatively, it could be that the bobbin pin is wrongly planed or that the needle is placed backwards. Take out the bobbin and insure that is placed correctly. Then take out the needle and put it back. Ensure that the flat side of the needle faces the back of the machine.
