If your dehumidifier is not collecting water please carry out the following checks:
- Increase the heat in the room to ideally 18 to 20 degrees centigrade.
- Clean the filter.
- Move the dehumidifier to another area for a short time.
- Increase the humidistat to a higher setting.
If the unit is not collecting water the environment may not have a high enough humidity level.
If the dehumidifier is considered not to be functioning correctly it may need to be inspected by an engineer.
