Possible Causes
Humidity setpoint too close to actual humidity, Faulty humidity sensor causing rapid swings, Oversized dehumidifier for room size, Blocked airflow causing overheating and safety trips
How to Fix / Troubleshooting
Safety: Unplug before internal inspection.
- Adjust settings: Set the target humidity to about 50–55% rather than the lowest possible setting to reduce cycling.
- Relocate unit: Place the Klarstein dehumidifier in a central, open area away from direct airflow from heaters or windows.
- Clean filter and coils: Ensure unrestricted airflow by cleaning the filter and vacuuming coils.
- Check humidity sensor: If the display jumps erratically, inspect and possibly replace the humidity sensor module.
