BWM0400 bionaire humidifier

We have just bought this unit and can't get it to work. the instruction say to wait for 5 beeps,,it just doesn't beep. therefore the remote is not connecting (apparently) we have tried several times. it has started to work for a few seconds and then the reset button comes one. this is to indicate that the tank is empty, which is not. we have emptied the tank and started over, but the same thing happens.

SOURCE: 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.

SOURCE: My Bionaire Humidifier

From the user manual (which is online)

2. Clean the base by partially filling
it with one 8-oz cups of undiluted
white vinegar or by using Cleanse
CleanTM Solution (DMS216) by the
manufacturer. Leave this solution
in the tank for 20 minutes, while
cleaning all interior surfaces with a
soft brush.

SOURCE: Reset light comes on, unit stops operating when tank is full

I was up all night with this since I just purchased it yesterday and I wanted to be certain that there wasn't some simple alternative to returning the humidifier since the reset light keeps going on immediately after I turn the unit on AND I've already followed all the directions to the T. Believe me - I was ready to return it cause ain't no 38.99 worth me doing all this tinkering and trying to figure out why they couldn't make the unit correctly cause apparently A-LOT of people have this problem. If it wasn't for my three children being so ill including myself getting sicker going out to purchase the humidifier and I was trying to avoid going back out to further compound my illness----I WOULD have just returned it. MAYBE I still will return it. ANYWAY, here's the deal: the water in the tank SHOULD flow into the boiling chamber where of course steam rises from there; however, the WATER VALVE in the CAP to the water tank does not allow any water to flow into the boiling chamber because it is so tight. The reset light goes on as if there was no water in the tank because of course, the heater is on, but no water is getting boiled because the water can't get in. There are a few things you can do. First: the water valve is a little stick and a spring within a piece of rubber that can be slipped out of the cap (this is what I chose to do). Now the water flows easily and even with the unit set to high, there is no problem. It just works. Second: You could remove ONLY the stick and spring from the water valve's rubber piece. This would work if the hole in the rubber piece happens to allow steady water flow (mine wouldn't). Third: you could probably do some cutting til you were satisfied with the results.

SOURCE: replace humidifier filter

turn the unit off then take the tank off then the base which is the fan portion and the filter fits right there.. if it's a round filter then it slips right on. now if it's the squares they will slip into some slots and usually they will take about 4 if that's the case. if you have any other question please feel free to let me know.

How do I reset a Bionaire BWM0400? The red "reset" light keeps flashing.

Your component has digital technology which has a tendency to 'lock up'.A reset solution for your problem is to simply unplug it for 5 minutes and plug it back in.That should fix your problem.If it is easier to pull the circuit breaker,that is fine also.Digital components are defined mainly as things which are programmable such as ovens and refrigerators with LCD or LED displays,thermostats,DVR's,answer machines,TV's and much more.Some things which are not exactly programmable but can be reset the same way are video game consoles,modems,battery operated devices,telephones. you have any questions or need more help,just comment here and I will get an autolink to your post and reply ASAP.Greg

I have bionaire cleaning product but no directions on how to use

the cleaning product that you have you need to use once cap full per gallon of water. so if it's 5 gallons you need to use 5 cap fulls. so forth and so forth. that is the easiest way to tell you. and then you let the unit run with the solutions and the water for the hole time until the water runs out. and your unit will be cleaned
