The OP is describing water coming into the house. Sounds
like a clogged drain, and sounds like the styrofoam is part
of the intended design.

There if often SOME water. The machine slings the condensate
against the
condensing coil to further cool it, thereby gaining
efficiency. There
should, I would think, be an overflow drain so that all the
humidity removed
from your room doesn't flood back in.

I suspect a clogged overflow drain.

See if you can find an exploded drawing of the unit on the
web.

I'm also suspicious of the hunk of styrofoam. Are you sure
its not part of
the original packing material? That is, does it come out?
