Fan is running but humidity is not changing

I replaced the cracked water tank last year and when I began using it this winter I am getting no humidity increase. The water reserve fills with water and the fan works but the water level remains unchanged. The water tank is working. Any suggestions?

Q: My unit has been running for several hours. I hear the fan spinning, but I do not notice the water level in the tank decreasing.
A:
First, check the filter to ensure it is wet. If the pad appears dry, remove it from the Base and gently rinse under cool water. Reposition wet filter in the Base. You may also want to note the current moisture level in your home. If the humidity level is over 60% the unit will not put out much moisture
as your air is already saturated.

UV bulb and filter are user replacement items

Comment by Soulvisitor, posted on Jan 20, 2008 You should notice moisture on the widows in the room after unit has run for awile, this unit carries a 3 year warranty. More info coming...

Fan is running but humidity is not changing - 4b54ac1.jpg Comment by Soulvisitor, posted on Jan 20, 2008 If water level in tank is dropping and fan runs then I'd say it is working.

OK?
Comment by Soulvisitor, posted on Jan 20, 2008 Q: I hear the fan turning, but I don’t see any mist. Is my humidifier operating properly?
A:
Dry air is pulled through the system and a fan disperses invisible, moisture balanced air. There is no
“mist” emitted. When operating normally you will feel only cool air coming from the unit. Monitor the
water level in your Tank/ Base. If you notice a decrease in the Water Tank over 24 hours then the unit
is operating normally.

Fan and tank lights won't run

I would look at the floating switch actuator. It's common for the float to bind up in the holder which keeps it in place. If the actuator is floating free, then look at the switch itself. Could be corroded or otherwise malfunctioning.

How and when do i clean the filter

I assume when you say FILTER-- you mean the wicking pad, right?
This is the pad that absorbs the water, and rotates into the path of the air stream- thus increasing the humidity in the room..

I just did a quick search on the internet, and I came across a review on this humidifier--- Here is what she says:

Usually we start running it in late October. It is December now and we have bought THREE pads already this year. One pad should last at least for the few months we use it each year.

If you are fussy, you might want to change it 2 or 3 times in a winter-- others might last thru the whole winter-- Obviously it will have less mold, and will evaporate better, the more often you change it.

Humidifier not working

Ensure there is water in the tank.
  • This may be caused by mineral deposits in the water channels. Try the following: Clean the water tank, base and vapor nozzel with a damp cloth to remove any build up in the water channel.
  • When was the last time the cartridge was changed. (If it’s been over 3 months, this could be the reason why the unit is not working properly.)
  • Unscrew the demineralization cartridge and run the unit, if it starts to mist then you need a new cartridge. (insert cartridge link here)
  • The screw cap for the water tank, onto which one first screws in the demineralization cartridge, has a small rubber gasket. make sure that gasket is not too far down against the outer screw cap. If it is the spring loaded button would not work properly to let the water descend into the base tank .
    The solution: push up on that small rubber gasket so that it is as far up and away from the screw cap as it can be without falling off, and voila! you get mist!!
  • If you have changed the filter recently then take out the cartridge and run the unit without the cartridge for about 15 to 20 minutes.

The power light on my Bemis 4D-7800 humidifier flashes.

On my water wheel several parameters must be met. 1. Power on, cord plugged in. 2. Water in tank, the float arm needs to move to indicate water present, the red light on the dash indicates no water. 3. Humidity controll set higher than the room atmosphere humidity, clockwise is higher on mine. 4. The fan speed selecter must be on either high or low, the fan won't run unless one position is selected. I hope this helps

Need to find a new water tank

Mine also cracked along the seam several years ago. I sealed the crack using two-part waterproof plastic epoxy (found at any hardware store.) Not really pretty to look at, but it hasn't leaked since!

Hunidifier doesn't add enough moisture to air

here is the link to the manual for the w7 - they suggest a replacement wick filter would solve the problem due to bacteria or mineral build up - i would expect this to solve your problem as the only way these wicks can not soak up the water to the top is if they are clogged or the tank is empty. try the cleaning routine on page 9 first - might be enough but the wicks probably will need replacing soon anyway. http://www.bionaire.com/manuals/W7_English.pdf Hope this helps :)
