Hope this helps you. Please let me know.

The E3 Code, indicates that the air intake filter needs to be removed and cleaned. Be sure the unit is OFF and unplugged before removing the filter. Filter cleaning should be performed at least once every two weeks, as part of Routine Maintenance.

Hi,
There are many reasons why a dehumidifier willnot work or collect water.
Here is a tip that I wrote to help people to figure out what is going wrongwith their dehumidifier

Dehumidifier is running but no water is in bucket

I have a 40 pint and a 50 pint that are very similar. The 40 pint has the e3 error. Experimenting with the 50 pint, I found if I disconnected a particular sensor I got the e3 error. That sensor is a little can with two black wires (smaller than a AAA battery but shaped like that). It is attached to the cooling coils so must be a temperature sensor. This is not the little circuit board sensor mounted in the middle of the radiator in a plastic box/clip thing.

I am now about to see that part to see if I can replace it.

You can get the manual of the one that you have listed under on the link below. If it is not the right one please give us the make and model # so we may get you the right one.

DE500P does not run and shows error code E3. What part do I need to replace and where can I get it?

Go to site...
safemanuals.com/references.php
in top search box show user manuals
go to search data base find delonghi- then type in de400 humidifier
then download

I am searching for a resolution to the E3 code (same init) and happened upon this request. The manual can be downloaded from DeLonghi.com but that advises you to call the service center.
