    I tried bicycle tube repair patches, too thin. Mostly sealed but still a little leak. I guess car tire tube could work.

    About 15 bucks for one incl shipping on the net. Too much.

    I will probably get another unit for double that at a warehouse store.

Mine did the same, I cut one out of a piece of inner tube rubber. It has worked just fine for two seasons.

No more steam. Want advice on disassembly.


There is info on the FAQs from Air-o-Swiss:
http://www.airoswiss.net/service/faq.aspx#35


Q: No mist / unit is not working / empty indicator keeps flashing
A: Fill up the water tank. Check if water is flowing through the demineralization cartridge (attached to the water tank cap). If the water tank is full but there is only little water in the base it indicates that the water is now flowing through the demineralization cartridge.

  • Wait for 15 minutes to allow the mist to come out of the unit.
  • If the unit is not working and the empty light is not flashing you might have set the desired humidity too low and the current humidity level in the room is higher. That is why the unit switches off automatically.
  • If the empty indicator continues flashing and the tank is full, water is not flowing through the cartridge. Exchange the cartridge or the granules in the cartridge after 2-3 months, in areas with hard water exchange the cartridge after 1 -2 months. However, the demineralization cartridge and or the granules must be exchanged at the latest after 6 months or the unit does not reach its full performance.
If the granules are new, see the following instructions:

  • Make sure the cartridge and/or granules were soaked for 24 hours, water takes longer to filter through dry granules in cartridge and into the base. Next, remove 2 tablespoons of granules from the cartridge, and throw them away. Too many granules in the cartridge it does not allow water to flow from the tank to the base.

Q: Unit is running intermittently.
A: How long has it been since the contents of the cartridge were replaced? If 2-3 months have passed, it is time to replace the contents of the cartridge. However the demineralization cartridge and or the granules must be exchanged at the latest after 6 months or the unit ceases operating at its full performance. If the contents of the cartridge were just replaced there are probably too many granules in the cartridge. Remove 2 tablespoons of granules from the cartridge.

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


REPLACING THE FILTERS
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
outlet.
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
securely.
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.
Cheers!

Humidifier not working


Ensure there is water in the tank.
  • This may be caused by mineral deposits in the water channels. Try the following: Clean the water tank, base and vapor nozzel with a damp cloth to remove any build up in the water channel.
  • When was the last time the cartridge was changed. (If it’s been over 3 months, this could be the reason why the unit is not working properly.)
  • Unscrew the demineralization cartridge and run the unit, if it starts to mist then you need a new cartridge. (insert cartridge link here)
  • The screw cap for the water tank, onto which one first screws in the demineralization cartridge, has a small rubber gasket. make sure that gasket is not too far down against the outer screw cap. If it is the spring loaded button would not work properly to let the water descend into the base tank .
    The solution: push up on that small rubber gasket so that it is as far up and away from the screw cap as it can be without falling off, and voila! you get mist!!
  • If you have changed the filter recently then take out the cartridge and run the unit without the cartridge for about 15 to 20 minutes.

Holmes HM4600HD humidifier tank


Mine dried out too. I could not find where to get the rubber valve seal for the tanks. Holmes does not list the part and when I called the rep told me they didid not stock the part. I solved my problem by purchasing thin rubber washers from Lowe's. They are 3/16 X 1 1/4 X 1/16 thick. The 3/16 hole in the center "snaps" on over the end of the plastic plunger just like the original. I had to trim the outside diameter with scissors to about 1" or using the old ones as a guide. Cost me $0.67
