Beurer dehumidifier shows E6 and stops operating.

Safety: Always unplug the dehumidifier before opening panels.

Basic checks:

• Verify room temperature: Use an external thermometer. Most Beurer dehumidifiers operate roughly between 5–32 °C. If the room is too cold or too hot, move the unit to a suitable environment and allow it to acclimate for 1–2 hours.
• Power reset: Unplug the unit for 10 minutes, then reconnect and test.
• Inspect the temperature sensor: Remove the front or side panel to access the evaporator coil. The NTC sensor is usually clipped to the coil with a metal or plastic clip.
• Check sensor placement: Ensure the sensor is firmly attached to the coil surface and has not fallen away, which can cause incorrect readings.
• Check wiring and connector: Trace the sensor wires to the control board. Reseat the connector and inspect for damage.
• Test the sensor (advanced): Disconnect the sensor and measure resistance at room temperature. Compare to service data if available. An open or shorted sensor must be replaced.

If E6 persists in a normal temperature environment after sensor replacement, the control board may be faulty and should be serviced by a professional.
