Dehumidifier shows P1 and does not start dehumidifying

Safety: Unplug the unit if you need to access internal components.

Steps:

• Check room temperature: Ensure the room is within the Sencor dehumidifier's specified operating range (typically above 5–7°C). Move the unit to a warmer room if necessary.
• Inspect for frost: Look through the grille at the evaporator coil. If it is covered in ice, turn the unit off and allow it to defrost completely.
• Clean filter: Remove and clean the air filter to improve airflow.
• Sensor check: If P1 appears even in a warm room with no frost, test the evaporator NTC sensor as described under E2 and replace if faulty.

Note: P1 may clear automatically once the unit completes a defrost cycle and the coil temperature rises.
