It's the float arm with the float that came out - it looks like it slipped out (yes the dehumidifier is unplugged ) of the enclosed box.
I thought I could just slide it back in, but I can't quite figure out where to slide it.
i think that the problem is , that you can't tell in what postion the receiving mechanism INSIDE the box is - when the arm came off , it may even have slipped into a position that's out of reach .
sorry 'bout that - well , there is always CT - but the repair may be costlier than a new dehumidifier , unless than of the floor people can help you .
btw. what about WARRANTY ?
the arm shouldn't just "slip out" , unless it wasn't securely fastened inside the box in the first place .
even if you were able to slip it back in , it would likely not be secure and come off again soon .
good luck !
