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 email you an Owners Manual. Be sure you have the correct model number for your unit, before calling.

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.

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.

The hose is supposed to be in the tank. Someone emptied the tank and forgot to put the hose back.

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. It's very odd. https://www.google.com/search?safe=off&rlz=1C1QJDB_enCA643CA644&sxsrf=ALeKk00f9Jx3klLUl0dKNUo5ffEHVuQLMA%3A1612057058213&ei=4gkWYNW0DJWq1QGmg6TQAg&q=DeLonghi+DN+125+R+Dehumidifier+replacement+filter ..

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

Not sure. Might have a blown fuse or bad capacitor.

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.

all this info is in the manual. Either you threw it away or are a person who does not like to read.

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.

Usually happens when the float valve is stuck in the down or up position try wiggling the handle to release or if the collection bucket is not sitting perfectly on the safety switch has to be down square I have the delonghi dem10 model always empty and unplug before checking

Dear Heemin, From the wording which you have used, it appears you think you are talking to the DeLonghi company. You are not. You are speaking to "fixya:". Please contact DeLonghi or one of it's dealers by finding their access information on your computer's search engine. God bless your efforts.

Are you worried as to why there is no Water in the Water Tank/Bucket at all? Well, a few operational basics must be understood by you please. For the unit to remove moisture from the air and draw water into the bucket/tank, the set relative humidity (%RH) must be below the current or ambient room relative humidity. Attempt to lower or reduce the setting you have to a lower value and it should start collecting water in the tank. Hope this helps

It's basically an air conditioner so if the fan is running---the condenser not plugged up via rats nest---lint----the float switch working---if possible tip over switch working----the system maybe low on refrigerant
