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?

Can you say how it stopped working, please? Does 'it would not start' mean absolutely nothing happens or what, please?

From what you've described, it seems that the "A" setting may be a special or additional mode of operation. It could be an "Auto" or "Adaptive" setting that adjusts the fan speed based on the humidity level in the room, or it could be a specific function designed for a certain type of room. I recommend checking the owner's manual or contacting the manufacturer directly to find out more information about the specific function of the "A" setting on your Aircare (Valiant) Humidifier HD1409.

if you can see how much water is in it just fill it when its down.otherwise figure out how the float switch works and find out why it doesnt now...common sense rules

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.

Don't use a hose, it will rust the motor and bearings.

if the blades are metal, and the unit is detached from the furnace. Try carburator cleaner or brake cleaner - out doors away from flames. Also, rotate so no solvents get to the bearings and wash away he lubricants. The solvent evaporates quickly but it will take a minute so don't be too impatient to get to the next blade.

If they are just dusty, and you don't want to dismount the unit, try some canned air - office stores carry this for cleaning keyboards and such. To get a really good stream, turn the can upside down and spray. The liquid propellant will come out and makes a really good cleaner. It will be cold cold cold as it evaporates and some ice will form if the humidity is high enough.

Effectiveness will depend on what is causing the dust to stick to the blades - oil film, soot from wood/coil/fuel oil and cigarette smoke are difficult.

automatic, meaning it will self adjust as needed to keep the humidity level consistant

If you are using large amounts of water and it is not leaking anywhere than I would be inclined to think that your humidity indicator is not correct. Do you notice any differences since you have been using it,such as less static electricity,skin and hair not as dry as usual or house plants looking better if you have any. Also not knowing what area you live in I don't have any idea what your normal atmospheric temperature or humidity are. Other factors to consider is how well your house is insulated,number of doors and windows and how many times doors are opened. Without knowing these things your humidifier may be doing all it can. Hope this is of some help.Thank

This is an old post, but you can make sure the humidity adjustment is full high. Perhaps it is defective or possibly, the environment is as humid as the high setting will allow.
