Display shows E13 and the humidity function or humidity display does not work correctly (on models with humidity control).

Safety: Disconnect power before accessing internal sensors or humidifier components.

• Locate humidity sensor: Typically mounted on the interior wall or ceiling, sometimes in a small vented housing.
• Inspect sensor and wiring: Ensure the sensor housing is intact and the wiring is not damaged or corroded.
• Clean sensor area: Wipe away any condensation or mineral deposits with a soft, slightly damp cloth and then dry thoroughly.
• Check connections: From the rear, trace the sensor harness to the main PCB and reseat the connector.
• Humidifier module (if present): Inspect any water reservoir or cartridge for leaks or blockages. Replace cartridges as recommended by mQuvée.
• Replace sensor: If readings are clearly incorrect or E13 persists, replace the humidity sensor with the correct part.
• PCB replacement: If a new sensor does not resolve the issue, the main control PCB may need replacement by a technician.
