8 Solución de problemas
Se tes problemas co teu deshumidificador, consulta os seguintes problemas e solucións comúns:

- Comprobe se o cable de alimentación está conectado correctamente a unha toma de corrente que funcione.
- Ensure the water tank is properly inserted and not full.

- Ensure room temperature is above 5°C (41°F), as dehumidifiers are less effective in cold conditions.
- Close doors and windows in the room to prevent humid air from entering.
- Allow a few minutes for the unit to accurately measure humidity upon startup, as initial readings may be inaccurate.
