I am responding to your concern based on my former washer which was a different brand.  If I overfilled the detergent or any of the compartments by even just a tiny amount, then there would be water in that compartment at the end of the cycle.  Sounds crazy, but that is what I finally concluded.  Typically I used a lot less then the maximum, but if rushing and not being as careful it did happen.
