Cause 1:

The position of the humidifier causes it to read its own mist

Solution 1 :
Re-position the unit so that the mist produced does not settle at the base of the unit.

 

Cause 2 :

Sensor air inlet is blocked with lint

Solution 2 :

Look at bottom of unit. If any ventilation holes are covered or partially covered with lint, clean them and retry.
