If the room air is less than the set air then there is no water in the bucket because there is almost no humidity in the air. If it is winter, there is likely not enough humidity in the air to have water collect in the bucket. A dehumidifier will only pick up humidity out of warm air. If you are running a dehumidifier in your basement in the winter, the room may be damp, but too cold for the dehumidifier to pull out the humidity. Try running the unit in the bathroom after having a hot shower without the bathroom fan on. If working correctly the unit should draw water.
In addition, check to see if the air filter is dirty and/or blocked. Also, the room temperature might be too low, (below 15.5 C/ 60F) and finally, check to make sure that there is no obstruction to the unit, that might be causing poor airflow circulation.
I hope this helps you to troubleshoot and solve the problem.
