Question about Humidifiers
EVAPORATER PLATE GETTING NO WATER
Try removing the cover, and manually cycling on the controler switch? Does the solenoid click on, next to the humidifier (the unit with the water line running through it, with wires coming out of it)? If it does click on, is water running down the water pad? It doesn't necessarily drain water when it's working correctly. All of the water SHOULD be getting evaporated into the air return duct.
If it's clicking on, but no water is running out, you should check the water supply saddle valve and make sure it wasn't turned off during servicing.
If it's not clicking on, you should test that you are getting voltage (12v-18v DC) to the solenoid. If you're not, check all wiring connections and make sure they're tight. If you still don't get power, you have either a problem with your control unit/humidistat, your DC power supply, or the control board on your furnace. You may need to call a HVAC technician at that point, depending on your comfort level/skill level in that regard.

I've been having problems with this unit since purchase in December 2007.
To fill, unscrew the cap with the spring loaded plunger. It may be tight, but it has two slots which you can turn like a screwhead using something wide enough (eg, a spoon) for leverage.
My problem is that this thing leaks badly. The fit of the cartridge is terribly designed. The one supplied is different from the one depicted in the unhelpful manual, which is silent on where the cartridge should fit. It will fit in one spot, but it will not sit flush with floor of the unit; it rocks and the water holding top rocks with it. The supplied cartridge appears to be an attempted and unsuccessful fix of a problematic design.
Even without the cartridge, this unit still leaks.
A web search shows others complaining about leaking. Hate to say it, but another example of lousy American design... but it sure is pretty!
Haven't been able to raise the manufacturer "Kaz" on the phone.

I am having the same problem. I have had my humidifier for about 5 years now and I just started having the problem where the water continuously flows through the solenoid. I took apart the solenoid by removing the fittings from both sides. When I did that, I noticed that there was a hole in the metal that allowed me to see through to the other side. Apparently, it had corroded and and broken through, allowing the water to pass through the solenoid without really going through the valve within the solenoid. There are several sites that sell replacements for about $70, which is not cheap, but cheaper than buing a new humidifier for $120. Here is one site I found: http://www.iaqsource.com/product.php/honeywell/32001639-002/?product=112783&category=1142

The screw does turn and will open the valve, take the hex nut off and turn the screw to see if water leaks between the valve portion and the hexnut housing. They used that same valve on many models, including the newer models. Make sure you are getting water to the valve.

Check for 24volts at the valve. Some techs install these so it only comes on when the furnace calls for heat. It should have its own transformer.

Loosen the brass fitting where it connects to the soleniod valve. If water comes out your saddle valve is ok. Carefully retighten this fitting. With the humidifier turned on loosen the first fitting down stream from the valve see if water comes out. if it does turn the humidifier off and see if it stops, it should. That will tell you the the valve is ok then, just clean the filter and the oriface. if it does not turn on and off check the wiring. if ok replace the valve.
