The dehumidifier turns on, fan runs but it doesn't dehumidfy and E3 is flashing on the display panel. I can't find a listing of error codes anywhere in the product manual or on the DeLonghi website.
Calling two service centers, they both indicated that the main circuit board needed replacing. This would need shipping the unit!!, part and then labor. I figured over $120 - not reasonable. I then took the unit apart and followed the wires from the compressor to the back of the unit. This is where the moisture sensor was located - upper left. You'll see this when you take the filter off. Anyway, I cleaned the face of this part with a old toothbrush, used some compressed air to remove any dust. I then followed the wires with the black sleeve that went to what I think is a temperature sensor - also on the left. The wires go to a sensor that is pushed into a copper tube that is part of the cooling tubing. Gently pull this out, wipe it down and re-install. I then plugged the unit in, set the humidity level and it now works. I just put the unit back together and the compressor is turning on and collecting moisture! I will run it a few days and keep checking on it to make sure it doesn't go into the 'E3' Mode. By the way, the repair shops I called really didn't have a clue what the E3 code was. Dennis
Hi,
There are many reasons why a dehumidifier will not work or collect water.
Here is a tip that I wrote to help people to figure out what is going wrong with their dehumidifier
Dehumidifier is running but no water is in bucket

I have a Delonghi DDE 50e with the same problem after working very well for quite some time (Fan runs, nodehumidifying, flashing E3) Have an older Delonghi (non electronic digital display type) which works fine in the same room.
I have the exact same problem with the fan working but E3 flashing. I have never been happy with the DDE40E. I had an old sears unit that worked fine for 20 years without missing a beat.
I am going to tear mine down and clean the sensors and see what happens.
Same problem, E3 just keeps flashing. The unit worked great for 3 years now just the fan works.
I have the same problem with E3 flashing and the fan running;
and I followed the recommendations, and reseat the cables from the controller to each of the two sensors. Also checked continuity of the cables to each of the sensors, and these are TOK. The resistance to the one that is connected to the coil looks like zero. Any ideas about how to test the sensors?
