Q: No mist / unit is not working / empty indicator keeps flashing
A: Fill up the water tank. Check if water is flowing through the demineralization cartridge (attached to the water tank cap). If the water tank is full but there is only little water in the base it indicates that the water is now flowing through the demineralization cartridge.

• Wait for 15 minutes to allow the mist to come out of the unit.
• If the unit is not working and the empty light is not flashing you might have set the desired humidity too low and the current humidity level in the room is higher. That is why the unit switches off automatically.
• If the empty indicator continues flashing and the tank is full, water is not flowing through the cartridge. Exchange the cartridge or the granules in the cartridge after 2-3 months, in areas with hard water exchange the cartridge after 1 -2 months. However, the demineralization cartridge and or the granules must be exchanged at the latest after 6 months or the unit does not reach its full performance.

If the granules are new, see the following instructions:

• Make sure the cartridge and/or granules were soaked for 24 hours, water takes longer to filter through dry granules in cartridge and into the base. Next, remove 2 tablespoons of granules from the cartridge, and throw them away. Too many granules in the cartridge it does not allow water to flow from the tank to the base.

If your issue is with the float and not the mister, then you have to make sure the float is tripping the micro switch that turns the machine on. Some units the filter will not allow the float to hit the switch if the filter is not installed correctly. If everything is in correctly and the float is tripping the switch, then the micro switch must be faulty.

would you describe your problem in a little more detail please?

sounds like the filter is not allowing air flow.

I had the same problem. I replaced the filter and cleaned the base and then it worked.

Question edited to add maker. Set too high or the room is too cold. Lots of models, and all produce water in mist form, and the droplets have to land. It is the nature of the machine. https://www.google.com/search?q=Air+o+swiss+humidifier%2C+too+much+mist ..

Is the little ultrasonic disk at the bottom of the mist tower clean, or is there hard scale on it? If there are hardened deposits on the disk they will stop it from vibrating. Be careful not to damage it by scraping or digging with a tool. I have found that the best way to clean it is with a Waterpik, turned all the way up. It often takes ten minutes of work to clear it off. This is MESSY, do it in the shower, or outside.

Mine was doing the same thing...first month of operation (installed toward end of heating season) = no problems with noise (bubbling, gurgling) though the duct work - started second year toward middle of season. Now its been running for a few weeks and is intolerable. I dug out owners manual and it did not address this at all. I dug out the installation manual and viola! Gurgling is caused by excess condensation in the steam hose. Sure enough the steam hose had a small area depression and did NOT have the constant downward slope necessary - installation instructions are VERY specific about needing a slope in order to allow condense to drain from the steam house. The zip-tie installation had slide down from a vertical stabilizing pipe & allowed for the hose to sag in the middle (nice install job slacker). I adjusted it and the SOUND IS GONE. Hope this helps someone else.

Without brand and model, my advice is definitely a shot in the dark. Only your manual or your manufacturer's site can inform you of what the flashing means. Here are some tips that might help you increase the humidity in your room: Check the humidifier's water level: Make sure that the humidifier has enough water to function properly. If the water level is low, the humidifier may not be able to produce enough moisture to increase the humidity in the room. Clean the humidifier: Over time, mineral deposits and bacteria can build up in the humidifier, which can affect its performance. Clean the humidifier regularly according to the manufacturer's instructions. Place the humidifier in the right location: Place the humidifier in a central location in the room, away from walls and other obstructions. This will help the humidifier distribute moisture evenly throughout the room. Use a humidistat: A humidistat is a device that measures the humidity in the room and automatically adjusts the humidifier's output to maintain a desired humidity level. If your humidifier does not have a built-in humidistat, you can purchase a separate one and use it to control the humidity level in the room.

Is this a mist generator with an ultrasonic element, popular for "health?" These have a wick and water is not going trough the dry wick by itself. One should make all of the wick wet, from bottom to top. After that the water keeps being taken up to the element until the device is stored and the wick dries out again. Another thought is that these ultrasonic elements are very similar to a buzzer, like in toys. Two round sheets of metal with plastic in between. This is not like having long lifetime. For expensive mist makers you could perhaps order a new element but I do not have high hopes. Being so vulnerable the humidifiers are shipped containing no water. It is important to rest the top of the wick in water also. Just making the wick wet close to the element does not help or gives bad results.
