    I have a W-6 with two tanks and it has gurgled from day one. It is the water and air exchanging places. Water going out of the tank and air going in. That is how it is suppose to work. The tank has a sort of vaccuum in it which allows the water to go out a slow rate and air to replace it thus the gurgling noise. I guess some units are more quite then others. Mine acutally sounds like my cat barfing up a hair ball.

The gurgling noise is the water going into the base. since you haven't used it in so long your going to hear some weird noises at first then they should go away. but before using it make sure that all dust particals and everything is cleaned. if you have any more problems please let us know.

My humidifier made gurgling sounds so I opened it again and there was water in between the two halves. Is that normal?

Making gurgling sounds and spitting water. Do i just need to send it back, it's only a few months old

Before I returned it I would clean it thourghly and refill with clean water and about 1/4 teaspoon of table salt. Run it thru a full cycle and see if that helps. You can also rinse it out and refill with a 1/2 cup of vinagar and run again.This shoul help loosen and clean any mineral deposits. Hope this helps. Thank you.

My vaporizer is making a quiet bubbling/gurgling noise. This is only the second time that I've used it, but I can't seem to find the instruction manual. What could this mean?

That is very normal...the sound is the water being turned to steam which is the "vapor" that comes out...
Everything is okay and perfectly normal.

Steam not released through spout but trapped

is the spout clogged? Try running vinegar through it, CLR is a good product, but may stay the plastic, if not eat it, so I recommend vinegar to clean the deposits that plug things up, it may smell a bit, but usually works. Once cleaned, use distilled water to keep it from happening again, or just clean regularly with vinegar.

How to clean bionaire bcm4530

the easiest way to clean the unit is to fill the unit with vinegar and water. it takes 1 cap full of vinegar per gallon of water. run all the water out of it. now if you don't like the smell of vinegar what you can do is take some bleach let it sit in the take for about 20 minutes. wipe out the rest of theunit with water and then rinse the tank very thoroughly before placing it back on theunit. once you have done that the unit will be cleaned. now ifyou don't want to do either one of those options. you can always call the manufacturer or check around and local hardware stores and they will have cleaning solutions taht don't have any smell or anything to them and you can put that in your unit as well. if you have any more questions please feel free to ask.

Humidifier stopped working after cleaning.

It started working again on its own. Not much of a solution!

I think some water must have got into the electronics and then once it dried, the humidifier started to work again.
