Plz tell me error code 21 how to fix it for ultrasonic comfort 400 nebulizsr
As you know, this is a medical device. I suggest you consult a medical professional about it as it affects your treatment. The device is Japanese in origin. The instruction manuals I encounter are written in Japanese. That may or may not prove to be an impediment to you contacting the company yourself for guidance. I am reluctant to advise you about the equipment as my guidance would be very, very general and your health is much too important for trial and error. A low battery can generate error messages. Turning it off, unplugging it, waiting a few minutes, plugging it back in and turning it on might clear the problem. Some nebulizers have a reset button.; I can't say being unable to read the manual readily. Assuring all its parts are assembled correctly is of course worth doing.
