Sounds like you have some problems with the body or the film back not interlocking properly. What you describe sounds like what it does with no film in the camera or if the dark slide is left in.

BTW What finder do you have? Mine has the WLF and the AEII prism.

I've linked a scan of the relevant page on this, theres no troubleshooting section in the manual.
