Replace filters light stays on even after changing wicks. How do I turn it off?

You didn't specify what brand/model of humidifier your using, but you can still try a couple of things. (Try the most logical first).
Try turning the control knob to the "test/reset" position & wait until the humidifier "on" light blinks; indicating it is resetting the timer & the change filter lamp will turn off.
I believe that you will need to do this while the furnace is calling for heat, if it isn't, turn up the thermostat and try it.

Package indicates wilter might need to be chaged once a season

You should probably follow the directions in the instruction manual, which do say how often to change it. If you wish to risk a moldy house or an unproductive filter you can use it longer than advised. I soak mine in 50% vineger 50% water for an hour to dissolve mineral deposits and kill fungus, so the wick doesn't become too clogged to operate. I believe this lets it last a few times longer, but it is a Honeywell model of filter and I don't know how that would work on your filter.

In response to an indicator light I replaced the filter. What must I do to turn of the same indicator light?

If you did not turn the unit OFF and unplug. it before changing the filter, do so now.Just repeat the process, but make sure the master ON/OFF Switch is OFF and the unit is unplugged before removing and replacing the filter. Be sure the filter is properly installed.Wait at least 5 minutes, before plugging the unit back in and Turning the Master ON/OFF Switch to ON. That should give the electronics time to rest themselves.

Hope this helps you.

I am having the water turn black even with daily water changes. Also when cleaning out the filter there are black flakes. Do I need a new machine. This one is only 6 months old.

If it's still under warranty, return it for replacement or repair. You will need your Proof of Purchase to do this. Something is leaking internally and contaminating the water.

I have lost my manual. readout on the digital display is CF. humidifier operates fine. what does the display CF mean?

It means Change Filter.

However, assuming that you have done that in the recent past, you probably want to know more. I'm not sure how this actually works (that is why it shows CF). I saw it for the first time after 2 or 3 years of using my humidifier. (And I had just changed the filter a week or so previously).

You may have to turn the unit off/on or even unplug it to clear the message, then it should operate normally.

How do I change the filter, (Holmes hm7204 Humidifier) Where does it go?

Through normal use, waterborne minerals and sediment
become trapped in the wick filters. The harder your
water, the greater the amount of minerals in the water,
and the more often you will be able to monitor the life of
your filters in your humidifier.
You will be able to monitor the life of the filters in your
humidifier by checking the FilterCheck® Indicator. After
60 minutes of use, FilterCheck® Indicator will move and
indicate your filters condition. New filters will register in
the section reading Good filter. After frequent use of your
humidifier, the FilterCheck® Indicator will let you know
when the filters need to be changed, see Figure 2.
When the needle is in the CHANGE section, this means the
proper amount of moisture is not getting into your air due
to the excessive minerals and sediment that have become
trapped on your filters. At this point, you should replace your
filters. It is important to change your filters as
indicated to obtain stated performance level.
To replace the filter, follow the steps below:
1. Turn the unit off and disconnect from the electrical
2. Remove the tank and main housing to access the base.
3. Remove the wick holder from the base of the humidifier.
4. Remove each individual wick and discard. Do not
remove rivet, replacement wicks come equipped with
rivets for easy replacement.
5. Follow the weekly cleaning instructions.
6. Insert new filters into each section of the wick holder
making sure the rivet attaches to the wick holder
7. Do not use wicks without rivets as this will not
produce the units intended output.
8. Replace the wick holder into the base and replace
main housing and then tank.
9. Repeat Operating Instructions.
It will take about 30 minutes for the humidifier to reach
maximum output.

Vicks humidifier

Even though you change the water every time, if it's like ours you will still need to clean it with vinegar about once a week. I have a container that the insert portion (filter or whatever it's called) will sit in and has just enough room to pour in 4 inches of vinegar. Let it sit for about 10 to 20 minutes and then run water through the part where the mist comes out while holding your hand over the bottom. After a few seconds allow it all to run through. Continue and shake it really good and continue on until it is clear. I was AMAZED at what came out the first time I did this and part of the time I used distilled water. Hope this solves the problem.

Water runs out of the bottom of the unit

Check your plastic water orifice. It is in the hose fitting connected to the outlet tube of the water solenoid. It should be a blue one. Mine was completely eaten through, allowing full water flow, and thus overflowing the distribution tray. I replaced mine yesterday and no more water drips. May as well reflace the filter on the inlet tube of the solenoid at the same time. I used a piece of very stiff, but thin, wire formed into a small hook to remove both old parts. Replacements are readily available from multiple sources on line.
