Have a look at the very bottom section of your .top file. I expect you
will see there that you have only your solute, and not your solvent, or
your ions, which were added to the .top after pdb2gmx was used. You need
to reproduce the whole of your setup protocol, not just the first step.
Better still, don't discard your old topology!
