I have a Delonghi DH25 dehumidifier. The green light came on after 15 years of use. What does the green light mean? Do I need to clean the unit or purchase a new filter?

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.

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

The normal operating temperature is above 65 F. Much below unless specially designed for low temperature they will freeze up.
They have a frost detector and will defrost but it is very inefficient and not practical. My experience they eventually form a block of ice on the coils. They heat the room in the process so in a moderate area they can raise the temperature and provide needed circulation.

In the past where the temperature is cool I have faced the output into a corner, raised it off the floor and once the unit got started the heat created from the unit kept the air warm enough to avoid freezing up the coils.

Always check for recalls. Some models have had problems and have been recalled. See the link below.

Again!!!! Unplug machine X 15 minutes. Then fill with water. Then plug back in! If still lit, you have a water scale (mineral build up) issue that needs cleaning according to owners manual

You may need a new fan motor. If you can get to this
motor, with the power disconnected, see if the blade
is free to move. Do you hear any sound coming from
this unit?

Hello,

First, make sure the reservoir is empty. If you plug the unit in and see a green power light, but the unit won't run, make sure the reservoir is properly inserted. Many dehumidifiers have switches or sensors to make sure that the reservoir is placed so that it won't leak. Look for these sensors and make sure the reservoir is engaging them. If your dehumidifier has a float or switch to indicate a full reservoir, make sure this switch isn't being tripped accidentally.

Good luck.

the motor is tight, (can't turn) lubricate the motor bearings with light machine oil. retest. rust causes this. the motor "tries" to turn, more power is needed, still can't turn, power exceeds safe limits: breaker trips.
