Dehumidifier doesn't collect water

Dehumidifier doesn't collect water.

If your dehumidifier is not collecting water, check these possible causes.

  • The air might be too cold or dry. For a dehumidifier to work at its best the room temperature must be above 60 degrees Fahrenheit and the relative humidity should be above 45 percent. The dehumidifier won’t operate in lower temperatures or humidity.

  • Clean the air filter and check that you can hear the fan running when the dehumidifier is turned on.

  • If the compressor is running and no water is produced after an hour, the failure is likely within the sealed system: a bad compressor, Freon leak or restrictions in the Freon tubing are all possibilities. Due to regulations, repairs of the sealed system are only performed by licensed service technicians.
