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 sensor...

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!

(your welcome).

no really..."de nada". :"don't touch your moustache" "Doye toche moche"(?), "prego".

E3 code...what to do? on

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.

My delonghi dem 10 dehumidifier is working and collecting water but but the pause is continuously flashing why is this

The flashing pause light on your DeLonghi dehumidifier indicates that the unit is in a defrost cycle. During this time, the compressor shuts off and the fan continues to run in order to thaw any ice that may have formed on the coils. This process typically lasts for 10-15 minutes before the unit resumes normal operation. If the pause light continues to flash even after the defrost cycle is complete, it may indicate a problem with the unit's sensor or control board. In this case, it is recommended to consult the user manual or contact a professional for assistance with troubleshooting and repairs.

I have a DeLonghi NF 90 air conditioner/dehumidifier. The dehumidifier does not appear to be working - first time I have tried to dehumidify. Have had this unit for about 8 years. Thanks, Niall

If the air conditioner works and is blowing out super chilled air, then the dehumidifier function should work. The function takes in warm moist air and passes it over plates which are marginally colder than the ambient air. The air condenses and drips into a collection tank, or some have drain hose for putting into a floor drain. After 8 years, it may need service and gassing up, but you may also have drier air than you think. Whether is works in AC Mode is the key.

Apparently NOWHERE! Contact DeLonghi direct https://www.delonghi.com/en-int/products/comfort/air-treatment/dehumidifiers This search query should have shown lots of places, Maker direct, Amazon, eBay and Appliance parts suppliers like Part Select dot com.

Can a Delonghi dehumidifier DH25 be connected to an outlet pipe to get rid of the water? It's working fine, but I ned to empty it nearly every day

Some dehumidifiers have provisions for connection of an ordinary garden hose to drain into a tub, a standpipe, or a sump pit.

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.
