Devola dehumidifier displays LO and does not dehumidify; fan may run.

Safety: No internal work is required for basic checks.

LO indicates the room temperature is too low for safe dehumidifier operation.

• Check room temperature: Verify the ambient temperature with a separate thermometer. Many Devola dehumidifiers require above ~5–7°C to operate.
• Move the unit: If the unit is in a cold garage, basement, or conservatory, move it to a warmer room within the specified operating range.
• Sensor check: If the room is warm but LO still shows, the ambient NTC sensor may be faulty. Inspect and replace it as described for E1.
