I've had several of these. The problem is the lip on their condensate tray where it channels the moisture down to the reservoir (or out to the adjacent hose outlet) is just too damned small. One problem could be is that the tray isn't fitted properly to where it snaps in. Unfortunately, to find this out takes a little bit of disassembly.I picked up a Hisense dehumidifier a few days ago because it was the ONLY brand I could find at Lowes. I opted to use a water hose for a continual gravitational feed, as stated in their manual. After hooking up the hose, the unit still drained into the bucket and turned off after 12 hours or so. There is nothing in the manual that says to flip a switch or similar to have it drain through the hose or anything remotely close to it.
So I call up their CS line. After speaking with 2 separate people going off of their instructions- unplug/plug in, hold for 30 sec., etc., the last person told me to tilt the unit to the right so it will drain. I restated what their manual says which is- Place on a flat even surface. They disregarded what I told them and repeated to lift one side up.
Well, this unit will stay in my garage until a name brand replaces it this weekend.
