Airo swiss #7133

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.

Forget the visually appealing white mist humidifiers that leave you with a white slime to clean up. Get yourself a warm mist humidifier without the hassle, works better and no mess to clean up!

Gererally according to the booklet in the box.
If you no longer have those instructions, simply clean out the
basin, make sure no mold, dust, hardwater or calcium is deposited.
Use a 10% bleach water solution to kill bacteria, and thats is basically it.
Just dont miss any spots, but humdifiers should be cleaned every few uses.

First make sure the tank is properly installed rock it a bit toi see if it is secully placed.
Then Unplug it for a gfew minutes. ther replug and reset it before you start it.

EZCal Humidifier Cleaner and Descaler is what the company recomends. Also if you do not have this using equall parts of vinegar to water use the brush that came with unit. Now with this at first use if using vinegar and water it will have an odor, but the EZcal is odorless

Interestingly enough as soon as I posted here, I was able to find the source of the problem. It appears that during cleaning the water level sensor, a bobber which normally floats as the water level rises, became stuck the to bottom of the water base - see below for the picture. I was able to use a small wooden spoon to lightly apply pressure and release the bobber so that it could float, and instantly the vapor started flowing again.

still usable- just leaky

Okay, I just started getting this same deal with my 7133 on it's third season. I found in a blog that if you hold down the button that controls the heat while turning the mist knob on, it resets the machine. It worked. The red light went green and I turned off the heat button for cool air and the upper light still stayed green. Fingers crossed this continues to work. good luck!

Soak it with vinegar for several hours then use a soft nylon bristled brush to scrape off the minerlized crust and rinse. You probably need to replace the silver stick & mineralization cartridge more often.

After you've cleaned it you can reset it by holding down the ON/OFF button for a few seconds.
