Obvious Dess reference aside, I take this to mean this is the wrong answer.
When you have a hammer, everything looks like a nail, essentially meaning when you have a solution to a problem you'll try to apply it everywhere even if it doesn't actually work there.
I think this is trying to tell us that just because we have this big important Dess related password number, doesn't mean it's the solution to this puzzle. (That said there doesn't seem to be one proper solution, at least a found one, but I get the vibe that 1225 isn't on the right track.)
