What to do if my Honeywell HUL585 power light is on but there is no mist?

If the Honeywell Humidifier power light is on, but little to no mist is being released, first ensure the water tank is filled. Then, increase the power output using the power knob or touchpad. Check that the adapter is fully plugged into the port on the back of the humidifier. Clean the nebulizer, following the cleaning instructions. Also, verify that all components are installed properly. This issue can also occur if the reservoir has been overfilled; remove the tank, pour the water out of the reservoir, and replace the tank.
