Removing a broken door hinge bracket on my Indesit Omega 1000 washing Mc?

When I try to remove the two screws holding the door hinge bracket to the main body of the machine. It would seem that said screws are not screwed into captive nuts. My fear is, if I unscrew the screws fully, the nuts will fall into the body of the machine and will be lost forever! If this is the case, can I get to the nuts and refix them by removing the top of the machine? Any advice giving will be gratefully received -Thank you.
