Humidifier wont stop leaking water at bottom - Holmes Products Warm Mist HM5700 Humidifier

Is the drain line clear?

Here is a link to your humidifier http://www.iaqsource.com/article.php/my-aprilaire-humidifier-is-leaking-what-to-do-about-it./?id=35

Hi they should be a hose going to a drain in the floor there are insrtuctions on the wed just google the make and model and you can down load them

If the water continues runs nonstop even when the heater is turned off, you might have either a bad solenoid valve or a bad humidistat. Simply disconnect one of the two low voltage wires going into the unit. If the water turns off then your problem is most likely your humidistat or the low voltage wiring. If the water continues to run even when the low voltage is disconnected you have a defective solenoid valve.
Good luck.......

Check the bottom of drain tube (tube connected to the bottom center of the bottom tray). Does water freely flow out the tube when the humdifier water feed is on?

If there is no flow from the tube and water is leaking from the bottom tray when the humidifier water feed is on then the tube or bottom tray is clogged with hardwater minerals or other material.

If the unit has not been used in a while it's possible a spider has take up residence by spinning a web in the bottom tray or tube.

The last poissible reason is the tray is cracked. You may order the tray from multiple sources on the web. Simply shop for model and price.

A leaking humidifier is a sign that the unit's filter needs to be cleaned/changed. I had the exact same problem on this model.

Sounds like the air flow is too great and it is blowing the water in the bottom of the tray around before it gets a chance to drain. Try placing your summer, winter damper at half closed to slow the airflow down a little.

Make sure the bottom port on the humidifier is seated properly in drain port. Make sure your drain line is not obstructed.

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.

My Air-O-Swiss U7142 has a leak from the very bottom. I found that as long as the water flows on to the "pan" that evaporizes the water, the water will come out from the bottom. Does anybody know how to fix this?
