No visible mist

That is expected. The EV100 uses natural evaporation and does not create the visible fog associated with ultrasonic units.

Fan stops with water present

The fan may stop normally when the room reaches the selected humidity set point.

Low output

Check tank water, the humidity set point, blocked airflow, and control settings before treating low output as a failure.
