Your Philips Dehumidifier is equipped with a sensor. Once the humidity level has reached the desired low level, your dehumidifier will stop collecting water until it detects higher levels again.

My Philips Dehumidifier does not work while switched on
Published on 02 July 2025
If your Philips Dehumidifier or 2in1 Air Purifier and Dehumidifier will not work even though it is switched on (it does not collect water), there might be a simple solution. Discover here how to solve it yourself.
-
-
When the water tank is full, your Philips Dehumidifier will go into purification mode only and will stop dehumidifying.
To solve this, please empty the water tank.
-
When your dehumidifier is in defrosting mode, it will not dehumidify. The defrosting indicator (see image below) will tell you it is in defrosting mode.
Your Philips Dehumidifier is designed to enter into defrosting mode when low temperature is detected. It will resume dehumidifying once it has finished defrosting.
