Dehumidifier displays P1 and does not start dehumidifying.

Note: P1 on many Cecotec dehumidifiers is informational rather than a fault, indicating defrost mode.

Steps:

• Check room temperature: If the room temperature is below the minimum operating temperature, move the unit to a warmer area.
• Allow defrost: Leave the unit plugged in and powered on; it may automatically defrost and resume operation once the coil temperature rises.
• Clean filter and coils: Unplug the unit, remove the filter, and clean it. Vacuum dust from the evaporator to improve airflow and reduce icing.
• Placement: Ensure at least 20–30 cm of clearance around the unit for proper air circulation.
