Why does humidity indicator light flashing

SOURCE: Just purchased Model 831000. Put into service, three speed fan doesn't work. just one speed. Flashes F then back to humidity number and back to F. Do I have a defective unit? Essick Air humidifier.

I am battling the same trouble with this. I have re-booted the unit several times, and it is not a panacea. I am currently working on it, and will report here my findings.

SOURCE: Essick 1208 has F fill light that will not go away. This causes the fan to shut down and also will not allow adjustments to humidity settings. Ideas?

if the light your referring to is the indicator for the bucket to need emptying , this is a very common fault to have on lots of dehumidifiers , its caused by the float sensor in the bucket to b slightly out of place , as it senses using a magnet to trigger a hidden switch , id look carefully at float and id bet its just not exactly right sitting in its slot to pivot on

Testimonial: "Sorry for the miscommunication. The Essick 1208 is a Humidifer, not the opposite. It keeps telling me to fill it, then it turns itself off, even though the reservoir is full. I have replaced the filters and cleaned the unit thoroughly. I am suspecting a sensor.."
