Hello.

The GE humidifier adds a continuous stream of cool mist intothe air, giving moisture to dry air due to cold weather or dry climate or tohelp those who desire additional moisture because of respiratory problems orallergies. Sold online and in many department or home retail stores, thehumidifier requires regular cleaning and maintenance for proper functioning andto help keep mineral scale or bacteria from growing in the humidifier. ·1 Connect the power cord on the GE humidifier firmly to a power outlet if thehumidifier is not working. Replace or reset the circuit breaker as necessary.Turn the power switch to "On" if there is power but the unit is notoperating. · 2 Fill thewater tank to the "Fill" mark if the mist output is low or notpresent. Wait 15 minutes after filling the tank and before starting thehumidifier to allow the wick filter to absorb the water for proper function.Turn the humidistat knob to a higher setting for higher output. · 3 Check the capon the water tank and close the cap firmly. Check the rubber tank cap ring onthe cap and reseat firmly to help provide a better seal. · 4 Replace thewick filter with a new wick filter, available through General Electric, if thewick filter inside the base turns brown. Replacement parts may be ordered bycalling 877-207-0923. · 5 Clean thewater tank with vinegar and a soft brush if the water begins to get cloudy.Rinse well before refilling with water. Use cold water in the tank, as warm orhot water may make the water appear cloudy. · 6 Loosen thetank cap slightly if the humidifier cycles on and off unexpectedly. Turn theknob to a higher or lower setting. Thanks.

A humidifier will not collect any water. A humidifier has a tank that you fill with water. The water is released / forced into dry air to make it moist, usually by a fan or ultrasonic method.

A dehumidifier has an empty tank that gets filled by the appliance extracting moisture from the air. The tank will have to be manually emptied periodically, otherwise the safety / water level switch will shut the unit off so that the tank doesn't over flow.

I suspect that you meant to say dehumidifier.. and if so, please provide the manufacturer's name and model. The "P2" indication will be difficult to interpret without knowing the manufacturer's info.

I have the same problem and I have 2 of them fairly new. I can't seem to find out what the problem is either.

FILLING THE WATER TANKS
1. Before filling the water tanks, push the POWER switch to the “OFF” position and
unplug unit. Refer to cleaning instructions.
2. Remove water tanks from base, turn each tank upside down and remove tank cap
by turning counterclockwise. Fill tank with clean cold tap water.
Replace the tank cap by turning clockwise. Tighten firmly.
3. Carefully pick up tank, since it will be heavy when full, and slippery if wet.
4. Place water tanks on base. Make sure tanks are properly placed, otherwise, the
humidifier will not work correctly.

Hope this helps!

1. Remove tank from base. Turn upside down and unscrew filling cap. Fill tank with clean, cool, distilled, or tap water. Water temp should NEVER be too hot or too cold. Return tank to base and let sit for a few minutes. Be sure the filling cap of the tank is tightened firmly.

2. Plug power cord into a 110-120V AC wall outlet only. Turn power switch to "on" position. Power light will illuminate. Turn mist nozzle until desired level is being released. Aim nozzle away from furniture and walls.

3. Always turn humidifier off when water runs* out. Unit will continue to operate when tank is empty.
*Humidifier will run up to 12 hrs on low; 6 hrs on high.

DO NOT LET WATER SIT IN TANK FOR LONG. THIS CAN ENCOURAGE BACTERIAL GROWTH.
Place unit on level surface away from direct sunlight.
DO NOT ADD MEDICATION OF ANY TYPE INTO THE NOZZLE, BASE, OR WATER TANK.
ALWAYS LEAVE ROOM DOOR PARTLY OPEN. DO NOT MOVE, TILT, OR EMPTY WHILE OPERATING.

Mild bleach and water solution for cleaning, never detergent.
Clean every 3rd day during use. Clean after long storage
Humidity varies from room to room. Aim for 30 - 50% relative humidity. If windows/ walls fog or frost, reduce mist intensity. If room too humid, ventilate by opening door or window; adjust mist intensity.

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 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.

3. Do not immerse the Base in water. For storage, wipe dry with a soft, clean cloth. Keep
water away from the Air Outlet.
4. Do not leave water in the Water Tank or Water Tray when unit is not in use as it may
result in the build up of mineral deposits and bacteria that can inhibit the output
efficiency of the humidifier. Please note that if water remains in the Water Tank for more
than a day or two, bacterial growth is possible.
5. Replace Water Tray with Wicking Filter. Then replace the Tank. Humidifier is now ready for
use.

3. Wipe all exterior surfaces of the Base with a soft, dry cloth. Do not immerse the Base in
water or use water to clean the base. An electric shock may result or the humidifier may
be damaged.

Hope this helps.
Good Luck.

On the Vicks v-3100 the water tank should lift off of the unit. Flip it over and there is a lid. Open the lid and fill the tank. Once you've filled it back up, put the lid back on. Flip the tank over to make sure there are no leaks, then put it back on the humidifier.

Note: It's very important to check to make sure the tank isn't leaking before you put it back on the humidifier, if it is, it will flood the reservoir, in turn causing water to leak out of the bottom of the humidifier (which is one of the major complaints about the 3100).
