What the heck is this on my floor?

Fresh from the realization that management actually hadn't fixed the problem with my sink came the equally ugly revelation last night that for some reason there was 4" of standing water in the bottom of my dishwasher. Which is just enough to dribble across the kitchen floor. Now, the truly weird part of this is that I hadn't run the dishwasher since Sunday, and it was all dry then, so where the hell did all this water come from? I called management again this morning and hopefully they'll have this squared away by the time I get home. It's kind of hard to avoid eating out when you can't wash your dishes.
