Delonghi de400p dehumidifier does not work

What is the specific problem? Is no water being collected by the dehumidifier or do you have another issue?

Make sure that the dehumidifier is in a room in the operating temperature range (at or above 44 degrees F). Make sure that the room door and windows are closed and that the room is not larger than 2200 square feet. Make sure that the collection bucket not full and is properly seated in the dehumidifier. Check and clean the air filter on the dehumidifier. (Vacuum the filter or rinse under running water three times. Then wait until dry to replace it in the dehumidifier.) Look at the coils of the dehumidifier. If you have ice on the coils, defrost the unit (turn off, unplug and wait for it to melt). If the ice reforms quickly, you may have a leak in the coolant system. Then the unit needs repair.

Next make sure that you have good air flow around the dehumidifier and that the desired humidity set point is lower than the humidity of the room.

I hope this helps.

same thing happend to me. I wasnt sure if it was the settings or me. I unplugged it for awhile, read thru the instructions turned it back on setting it according to the instructions and it began to work again. Not sure if it had to do with the unit being off for awhile or I entered the correct settings. Im just happy it began to run again

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.
