The unit is full of water but it keeps flashing f then 20 then f again and so on...this is a new unit I purchased yesterday. Also when pressing the speed button to change the fan speed nothing happens keeps flashing f then 20... Help? Should I return it?
The water level sensor fell into the fan. Unplug the humidifier from the wall, stick your hand in between the fan blade and locate the sensor. It is a small black rectangular piece the size of a nickel but rectangular and 3 nickels thick. It also has a 2 inch stem sticking out of that clicks back and forth when you push it. Stick the sensor back into the sensor whole and the flashing f will go away and the humidifier will come on again.
