Only thing I can tell you to do is to make sure that the evaporator in the back is ice and cold. If the evaporator is not cold the unit will never remove moisture from the air. And if that is the case you have a sealed system problem. The unit may have a leak so there is no gas in it. The compressor may not be working or the humidstat my not be working properly. So check those thigs out or if its under warrenty call for service.

I had a similar problem with the pump not working and the water flowing into the main drainage bucket instead. I had to disassemble the housing...not an easy project to reassemble...and found that the pump has its own smaller drainage tank with a float device, a pump pre-filter, the actual pump, then of course, more drainage tubes. The entire pump drainage system of components needed cleaned of accumulated, mucoid, slime! I cleaned the channel in which water flows into the pump's tank...located on the screen filter side of the dehumidifier. Then I moved to the other side of the dehumidifier and cleaned-out the entire pump drainage tank. Note that the pump's drainage tank only empties about 1/2 inch of water each time the pump activates. Thus, there is always alot of water in the pump's drainage tank. Thus, alot of time for slime to accumulate. Next, I cleaned off the float mechanism. I then cleaned-out the pump's pre-filter. Cleaning out the pump's pre-filter was paramount to the pump functioning properly and quietly! I checked that my pump was properly installed and NOT rubbing against its mounting so that it operated quietly. I added fresh water to the pump's tank several times to insure that the pump was working properly and that all slime was eliminated. Finally, I reassembled the housing...not an easy task! My pump now functions like new. All this work had to be done to insure proper function of the dehumidifier's pump system. My dehumidifier is only 11 months old. It is still covered by the one year warranty, but it is too expensive to ship the entire unit, as Delonghi requires you to do at your expense for them to fix it under warranty. You can be assured that I will check for future slime build-up to keep my dehumidifier functioning properly. The dehumidifier works great, it's just that it's high maintenance.

I have the same problem on ocassion.
I just remove and reseat again , making sure the front of the tank is flush with the unit. sometimes a little more push in does the trick

I think that I am having the same problem, but I'm not sure that this tube needs to be plugging into anything. However, my humidifier seems to be draining out of this tube rather than from the tray into the bucket.
