Frequently Asked Questions - MDDF20DEN7WF COMFEE

What does error code P2 on the display mean?
The P2 code indicates that the water tank is full or incorrectly positioned. Empty the tank and reposition it correctly for the appliance to restart.
What to do if the screen displays 'ES' or 'AS'?
The ES (temperature sensor) and AS (humidity sensor) codes are sensor errors. Unplug and replug the appliance; if the error persists, contact customer service.
The appliance does not start, what to check?
Check that the plug is fully inserted and the circuit breaker has not tripped. Make sure the water tank is in place and that the ambient humidity is above the set level. The appliance may also be in 3-minute protection after a stop.
How to install continuous drainage?
Remove the rubber plug from the rear outlet, connect a drain hose (diameter 13.5 mm) and route it to a floor drain. Make sure the hose is horizontal or sloping downwards and is securely attached.
Why is there water on the floor around the appliance?
This may be due to a poorly connected drain hose or a mispositioned tank. Check the connections and that the drain plug is properly in place if using the tank.
How often should I clean the air filter?
The air filter should be cleaned every two weeks (or more often if needed). Remove it, wash it with soapy water, rinse, dry completely before reinstalling.
Frost forms on the coils, is this normal?
Yes, it is normal. The appliance has an automatic defrost function: the compressor stops and the fan continues until the frost disappears.
After a power outage, does the appliance restart by itself?
Yes, the auto restart is active. When power returns, the appliance resumes with previous settings.
How to set the timer for delayed start?
When the appliance is off, press the Timer button then use the ▲/▼ keys to set the time (0-24h). The timer is confirmed after 5 seconds.
What refrigerant is used and what precautions to take?
The appliance uses R290/R32 (flammable refrigerant). Do not puncture, do not burn, and install in a room larger than 4 m². Any intervention must be performed by a certified technician.

What is the SMD function on the COMFEE MDDF20DEN7WF dehumidifier and how do I use it?
Frequently Asked Questions - 30/04/2026
Response Notice-Facile

The SMD function stands for Smart Dehumidifying Mode of the COMFEE MDDF20DEN7WF dehumidifier. It is an optional function that allows the device to automatically control the ambient humidity within a comfortable range of 45% to 55%, taking into account the room temperature without requiring manual intervention.

How the SMD mode works: once activated, the dehumidifier automatically regulates the humidity level to maintain optimal comfort. In this mode, the manual humidity adjustment function becomes inactive as the device manages all parameters automatically. The dehumidifier continuously adjusts its operation to avoid humidity fluctuations.

How to activate the SMD mode: press the Mode button to select the desired dehumidification mode. The MDDF20DEN7WF offers four different modes: Dehumidification (normal), Drying Mode, Continuous Mode, and Smart Dehumidifying Mode (SMD). Select the SMD from these options displayed on the control panel.

Benefits of the SMD mode: this mode is ideal if you want automatic and optimized operation of your dehumidifier without having to regularly adjust the settings. The device adapts at every moment to temperature and humidity conditions, making it the most comfortable mode for prolonged use in living spaces (bedrooms, living rooms, etc.).

The other available modes are Normal Mode (allows manual adjustment of humidity and fan speed), Drying Mode (designed to speed up drying laundry in a closed room with fixed fan speed), and Continuous Mode (operates the device continuously without stopping).

Procedure to activate the dryer mode:

  • Press the power button (button 1) to start the device.
  • Press the mode button (button 2) several times until the drying operation indicator lights up, indicating that the Dryer mode is selected. The device beeps with each mode change.
  • Adjust the fan speed (button 5) to three levels according to your needs: low, medium, or high speed.

Important: The Dryer mode is an optional feature on some MDDF20DEN7WF models. Check that your device has this option by consulting your exact model or by attempting the procedure above. Once the dryer mode is activated, the device will dry the laundry by reducing the humidity in the room. Ensure that the water tank is empty or that the drainage hose is properly installed to avoid overflow.
