20 Most Recent Honeywell QuietCare HCM-630 Humidifier Questions & Answers

How long are you going between filter changes?

A filter that stops wicking water up and turns orange/yellow is one full of deposits.

It sounds like you have hard water. How are you filtering this water before you use it? Distilled water is the best.

Replace the filter. They don't last forever. Mine normally last a month to a month and a half.

Good Luck

I am surprised that this answer isn't found anywhere, including in the manual from Kaz. If yours is the same version as mine, and your lights aren't even lighting up on top, most likely your float may have gotten bound up with gunk (the float rises up when the pan is full enough of water, which enables the motor to run. It is held into place by a plastic bracket with two phillips head screws, and looks a bit like a plastic bottle with a narrow neck in a small rectangular shape (not open at top). Remove the screws and the bracket, and take out the float and clean it and the reservoir (in the base) it sits in. Reinstall, and the float should move freely. Problem solved!

If you can locate a crack in the clear plastic tank, there may be a chemical you can buy to "weld" the crack closed. If you aren't sure what plastic it is, you might try sealing the crack with bathroom caulk that is mold resistant. You must locate the source of the leak and patch that.

I am wondering if the floater is sticking. I have the same problem and there is no crack like others have mentioned. But when taking it apart I noticed the floater which is the piece that sticks up from inside the base was not easily moving. Taking it out tonight after work and cleaning it along with the filter.

I was having the same issue. I noticed that when the main fan unit was removed, there was a small plastic piece that was sticking up from the base next to the filter, which has a female end on the fan unit. I played with this, and realized I could lift it up. Once I did this, I replaced the fan unit and it started working. I think this is the water level reader which, when all the way down, won't allow the fan to start since it thinks there is no water.

filter needs to be replaced

Honeywell... | Answered on Dec 19, 2010

Found a hairline crack in the water canister. Had to locate by filling the canister and waiting for a couple of minutes for water droplets to form outside the canister. This ever so slight crack allowed air to enter the chamber and made changes to water dispensing rate which overfilled the resevoir over time ( hours). The cracks were not visible under 10X magnification without the water droplets.

It may not be large enough to bring it up depending on the size of the space. I would try hot water on pad, and maybe even boiling water as well as turning on a shower to get it up. Then use hot water to maintian it.

Turn on furnace and urn up humidistst to call for it. Tube from solenid to the filter should have water running if water is up to the valve and solinoid is opening . It should be warm to your touch., Using an ohm meter you can sheck the coil it shuold have continuity.

Look for a microscopic crack in the water chamber. Leaking air will allow the water to continue to drain out of the tank. A bit of glue and duct tape over the crack should fix it.
