Re: Dehumidier Delonghi DH400P not removing any water...
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.

It is normal for a dehumidifier to discharge warm air. A dehumidifier is really an air conditioner - a fan blows humid room air across a cold fin coil that causes the moisture to condense on it and drip into a container - thus cooling AND dehumidifying the air. The cool air is blown over the warm coil and discharged out the back. A dehumidifier WILL normally increase the temperature of the room it is in. You can do the same thing with sitting an A/C unit on a stool in a room. Room air will be drawn in, cold air will come out the front, hot air out the back and water will drip on the floor. And, the room will get hotter, due to what is called "heat of compression" even though you're running an A/C unit.
First, try cleaning out your filter if you haven't already. It gets angry if it can't get any air.
If not, I don't know how brave you are, but I ripped mine apart to fix the problem. I took off the panel with the filter (5 screws) and you can see a collection tray with another little collection gutter under that. Both of mine were filled with junk, mostly dust that had gotten wet to make this awesome disgusting sludge. If you can get at it from there, try to clean the sludge out of the collection tray and the little gutter. I ended up taking my whole unit apart so I can get the collection tray out (dumb design, you have to take apart the whole dang casing to get at two screws that hold the collection tray in).
On the side with the lint screen, remove the five screws holding the top
panel in place. The sensor that needs to be checked in mounted on the
radiator fins. Remove the sensor and 4 pin connector. With a pin,
remove the loose fitting housing the "sensor"...a circuit board that
"shorts" with condensation...check corrosion and look for component
damage on the oft chance the circuit board was damaged by some
inappropriate poking or mechanical failure. Reassemble and replace
For a short life span...or out of warranty and only at your risk (IF
have significant other or kids or pets or human DNA... don't do this...)
.. guide wire through screen notch and attach to outer screen. Build
fortress around exposed sensor and talk to insurance agent for a special
rider...seriously be careful.
Did you? Clean screen and GENTLY clean fins of lint, etc....(vacuum's brush head should do the trick...)
Taking all appropriate safety precautions.
Here's the 100,000 (yen) tip....with humidifier unplugged, hold down the
power button (green button in lower center) and plug in the appliance.
Watch the LCD screen as it conducts a self test...and wha...lah!.
Should have a working humidifier!
no really..."de nada". :"don't touch your moustache" "Doye toche moche"(?), "prego".
It is more than likely the compressor is not running, only the fan. It seams that the humidity sensor is flaky on these units. You can, operate the unit, by opening up the dehumidifier and unplug the sensor from the main board. The unit will cycle on and off and remove the water from the air.....good luck
