Hi and welcome to Just answer.
Honestly I am not familiar to the steam press because that is not a sewing machine and I believe no one expert here on that category. However, I so flexible and I try my best to help you on your problem. What I need is a photos/video on the machine and its parts. I believe that you forget to place the spring properly.
To send photo, click the paper clip icon at the top of your typing box, click browse,select file then click Ok.
May I know if your machine is now working fine?
I'm just following up with you to see how everything is going. Did my answer help?
Let me know,Chester
