Fill Water Tank.

Turn off humidifier and unplug the power cord from A/C outlet. Remove tank from

base. Turn upside down and unscrew filling cap. Fill tank with clean, cool, distilled,

filtered, or tap water. Do not attempt to fill unit through Vapor Nozzle. Water temperature

should NEVER be too hot or too cold. Extreme temperatures can damage the

unit. Tighten filling cap firmly. Return tank to base and let it sit for a few minutes. For

first time use or when replacing the demineralization cartridge filter, please soak the

filter in warm water for several minutes.

You have a cool mist humidifier there is no steam. Please read manual or look up unit on internet

From the quick research that I did I'm finding 100 hours. That will vary very significantly depending on the mineral content (hardness) of your water. If you have alot of mineral in your water the filter may have to be changed much more often to maintain good operation of the unit.

Filters need to be changed regularly depending on environment may have to change more often.

These systems can be very troublesome. It is possible that you are having mineral buildup in your system from the water supply. You can try adding 1/4 cup vinegar to your water to help clean away deposits. See if that helps .

This has happened to me. Check the contact points in the base of the machine. Ours had some corrosion on them. I took an emery board and filed the corrosion off to clean the contact points.

it might be the cap that releases the water has a faulty seal. order one from [email protected]

My unit was doing the same thing as others here and I was able to fix the issue. I believe the issue is that the sensor for the water level, which is located in a tube connecting the two water reservoirs in the main unit, has something blocking the sensor. Most likely this is bacteria growth or other debris which has built up over time. I used Oxy Clean which has some bubbling action and very hot water to clean both sides for about 30 minutes. When I flushed out the reservoir, it started working again.
If take the base off the unit by removing the 4 screws, you will see the "tube" I'm talking about. Since this has what appears to be sensors in it, I didn't want to remove the tube from the bottom to clean it and instead to the approach above. Hope this helps someone.

I have tried looking for a manual for you but I could not find anything after a long search, however here are the contact details for venta, they should be able to send you a manual/guide

Caring For Your Venta-Sonic Humidifier
IMPORTANT!
Always unplug the unit before cleaning!
When to Clean Your Humidifier

Clean your humidifier weekly or more often during heavy use, depending on your
individual water quality. Clean your humidifier before storing and after long periods
of storage.

When cleaning the inside of your unit, keep water away from the air outlet. Exterior
may be wiped with a damp cloth when unit is off and unplugged.
Cleaning the Oscillator and Water Sensor

Turn off the unit and unplug power cord. Remove tank from base and empty
reservoir in base. Use cleaning brush provided in base to clean off mineral deposits
and sediment from oscillator and water sensor. Do not scrape or clean with tools
that have metal parts. Be careful to not damage the surface of the oscillator.
ATTENTION: Damage to the oscillator may cause the unit to not work properly.

The oscillator (ultrasonic transducer) is highly sensitive. Keep this important part
clean and treat gently. Do not touch the oscillator while the unit is operating.

Do not use soap, cleaning agents, detergents, or other chemicals for cleaning the
tank and humidifier.

After cleaning fill water tank (see instructions above) and return tank to base.
Storing the Venta-Sonic
Switch off and unplug power cord from A/C outlet. Empty remaining water from base
and tank. Clean tank and unit (see for instructions above). Make sure all parts are
thoroughly dry—allow at least 24 hours to dry. Leave the filling cap of the tank
loosened. This will keep the cap and gasket from sticking together. Pack Venta-Sonic
in original packaging and store in a cool and dry place.
