Question about Honeywell HCM-300T Humidifier

1 Answer

Water Tank leaks all over the floor

Suddenly, water seems to be leaking out of the unit all over my floor. It is also spraying out of the vent as well. This started to happen after a few weeks of regular use - things were basically fine, the room was being humidified very nicely. But suddenly, this problem occurred. I cant seem to understand why it is happening. There are no cracks in the tank, and the tanks 'sealed door' seems to be snugly sealed. Please advise.

    Humidifier was running well for a couple of weeks. It leaked all over the floor this weekend, and is spraying water out of the vent.

    It ran fine for the last two years. I got it out this year to use, put in a new filter (soaked) and when I put the tank in it instantly poured out the bottom of the humidifier. Tank is not cracked. What's up with that?

    I have the same problem. Water comes pouring out of the bottom of the unit. I do not see any crack in the tank, so what is causing this??

    I have the same problem. The unit is brand new. The first night, it ran fine. Now, water spits out of the vent rather than spraying in a fine mist, soaking the floor. I tried turning the humidistat down to 2 droplets (2nd lowest setting) but it did not make a difference. No cracks that I can see. The unit makes a sound like freezing rain hitting a gutter. Anyone have any solutions?

This happened to me the second night of use.  Water all over the carpet and a dripping vent. I called customer service and they told me to remove the tank and filter, and run unit dry for an hour or so. Then restart it.  Worked fine after that.  I think we may have bumped it which is said to be the cause of most leaks.  Bummer is that after 5 night of use the grip on water tank slipped and the tank is in pieces.

Why does my humidifier make the floor all wet


You may be over filling the unit. Take the refillable water tank out and with the power removed try to remove all the extra water where the tank goes. check for anything that looks cracked inside the unit the best you can. If the tank is seating properly it should not leak. If it is filled properly it should not leak.

Our HCM-640bw Honeywell humidifier will leak water onto the floor. If I fill the tank and let it sit without turning it on, no leaking. When it runs for about two hours it leaks bad. Any ideas on how to...


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.

HCM 640bw leaks


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.

Need to find a new water tank


Mine also cracked along the seam several years ago. I sealed the crack using two-part waterproof plastic epoxy (found at any hardware store.) Not really pretty to look at, but it hasn't leaked since!

LEAKS


Try to just fill the tank with water and set it upright on a table. If it leaks, the tank is cracked and needs to be replaced. Order one at kaz.com (search using model#). I have had this tank leak if the special cap is not sitting properly on the base. Make sure that the steam tower is properly locked in place before you place the water tank in the reservoir. The cap on the tank has a spring release that has to be correctly lined up so it only releases water when the water level in the reservoir drops.

Very little water left/ fills up and leaks


**With the unit unplugged**
the float sensor is probably getting sticky with residue and buildup (lime, grime, etc). Try cleaning the little float and that area. It should move easily when clean.

Bionaire BCM645 Cool Mist Humidifier leaking water


There is probably a crack somewhere in the unit. Not likely, but worth visually inspecting closely.

Try filling it with less water and run it and see what happens.
