Works well but
Yup, they eat energy.
An electric dehumidifier includes a refrigeration cycle that is very similar to a window AC units and refrigerators. They cool the air in the basement to condense and collect water and remove humidity, heat the air as a required consequence of the refrigeration cycle and dump it back to your basement.
Two sources of humidity in basements include warm outside air that naturally cools due to below grade earth contact and water passing from the ground though the floors and walls and evaporating into the basement. Dehumidifiers do most of the work in the summer when higher temperatures outside enable air to hold more water content.
In the winter, cooler outside air contains less moisture by weight eventhough it may be raining and the relative humidity in basement will be less because the air is warmed relative to the outside. The lower moisture content in the winter also absorbs the water passing through the walls and floor.
From an energy perspective, you may want the humidity set NOT below 50%. This will keep humidity below the level mold desires, but prevents the dehumidifier from doing more work and eating more energy than needed. A cheap battery powered temp/humidy meter left in your basement will help. Sources that include the "mold triangle" (temperature, water & food) often separate fact from expensive hype.
If the dehumidifier doesn't keep up, consider adding a moisture barrier to the basement walls and floors such as Dry-lock and floor paints to ****** moisture entry. Moisture barriers act very similar with water as insulation does with heat. They don't eliminate the need for a dehumidifier, but they reduce the work they do and energy they eat.

Pump not working
If you've checked power to the pump and it isn't working, it needs replacing, unless it's blocked with slimy deposits. Try a vacuum cleaner on the drain hose outlet

Error code E3 on delonghi dehumidifier DH400P
Be Safe or don't do it....
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".

Unfortunately, Delongi doesn't list an Owner's/Operational Manual for your model dehumidifier. However, you can contact their Customer Support Dept at 800-322-3848. They can provide you with the Error Code solution, as well as email you an Owners Manual. Be sure you have the correct model number for your unit, before calling.

How to remove the back off Delonghi dehumidifier dd50pe. Stuck around the handles.
David Mury Oct 20, 2019
On the back there are two top screws, two middle screws, and one bottom screw. Make sure the hose attachment is off. On the front there are two bottom screws. Each side has one screw at the bottom (longer than the rest). Remove all that I have mentioned. You will need to wiggle the two halves apart but they will come. Once the back has been removed, there are two more screws on the inside that need to come out before you can get the front sleeve off. Good luck.

My DeLonghi DEM10 wont power on any more - like fuse gone
The tank may be full. Your dehumidifier has a safety device that turns off the dehumidifier when the water tank is full. Usually the tank itself either presses against a switch or there's a device connected to the tank that triggers a switch when the tank is in place and full.
If you've emptied the tank and the unit doesn't run, inspect the place where the tank rests to see if there's a switch or mechanism that's not being activated. You may be able to turn it on with a simple flick of your finger.
