There are a few hose connections inside the unit related to the heater element. Water flows from the reservoir down into the unit, takes a turn into a tube with the heater element wrapped around it, then turns back up into the mister area. Any of the four connections (base to first elbow, elbow to heater tube, heater tube to second elbow or second elbow to base) could be leaking.
The white ring around the mister disk cracked on my unit, letting water leak out the bottom as you describe... Take a close look at that.
It's also possible the base itself is cracked somewhere... Look closely at the mister and reservoir areas of the base for cracks.

Flashing red flight


Its probably the cleaning light that comes on periodically to remind you to clean the unit. Shut off the unit AND when you do so hold down the power button for several seconds until the flashing red light shuts off. The cleaning light should stay off until the next cleaning is due.

Per the Air-O-Swiss FAQ:

Q: Cleaning light is flashing (AOS U650, AOS 7135, AOS 7142, AOS 7144, AOS 7147)
A: Switch the unit OFF and unplug it. Empty the water in the base. Rinse the base with hot/clean water. Do not submerge the base! Visually inspect the base for dirt or mineral build up. If soft water is used decalcifying the unit every 4 weeks with EZ Cal is suggested. If hard water is used the unit should be decalcified every 2 weeks. Do not forget to reset the clean light after resetting the unit.

Q: Reset cleaning light (AOS U650, AOS 7135, AOS 7142, AOS 7144, AOS 7147)
A: The cleaning light does not automatically reset. Hold down the power button (button A in instruction manual) until the light stops flashing. The light automatically comes on approximately 14 days after plugging in the unit.

My air-o-swiss 7142 humidifier keeps giving me the empty indicator light to signify no water in the unit even though the base and the tank are full. If I try to reset it comes on for seconds and then shuts...


The water sensor is a float in the mister area of the base. The float is off in one corner with a little plastic barrier around it and translucent cap over it. Make sure the float can more freely. If the float can move up and down but the light stays on, the reed switch (a switch controlled by a magnet built into the float) inside the unit might have been knocked loose, damaged or disconnected. The switch is actually inside the post that the float slides on, but it can only be accessed from the underside - inside the unit.

Did you check the orifice inside the supply water tube? Sometimes the orifice can come loose and allow to much water inside the humidifier.

How to clean air-o-swiss humidifier?


Gererally according to the booklet in the box.
If you no longer have those instructions, simply clean out the
basin, make sure no mold, dust, hardwater or calcium is deposited.
Use a 10% bleach water solution to kill bacteria, and thats is basically it.
Just dont miss any spots, but humdifiers should be cleaned every few uses.

Water runs out of the bottom of the unit


Check your plastic water orifice. It is in the hose fitting connected to the outlet tube of the water solenoid. It should be a blue one. Mine was completely eaten through, allowing full water flow, and thus overflowing the distribution tray. I replaced mine yesterday and no more water drips. May as well reflace the filter on the inlet tube of the solenoid at the same time. I used a piece of very stiff, but thin, wire formed into a small hook to remove both old parts. Replacements are readily available from multiple sources on line.

Water is leaking from the bottom of the unit


The tune up kit that I ordered arrived on Friday and I installed most of it on Friday night. While it is nice to have a new frame and the distribution panel and I think the price of the whole kit was fair considering it comes with the parts and 2 water panels, the fix was really simple.

The kit came with the water distribution tube with with a new blue orifice (Aprilaire #4232) already inserted. This orifice is in the end of the plastic tube at the solenoid end. When I removed the old water distribution tube, the old orifice was not really dark blue anymore but kind of a light blue and was deteriorating from 12 years of exposure to the chemicals in the water. What should have been a pin-hole size opening in the orifice was up to about 2mm or a little more so the orifice was letting way too much water through.

If anyone else has this leaking problem, and your orifice is several years old, I would check that first. It is a $2.75 part and may be the cause of the leak. The whole feed tube kit is only $8.75 and includes the feed tube, nozzle, orifice, ferule, compression nut, strainer so if you need to replace the orifice, I would order the whole feed tube kit for a little bit more.

Hope this helps,
Roger...

General Humidifier Model 1042-L leaking water


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.

I have a General Humidifier Model 1042-L that is leaking water out of the bottom pan. How do I fix this?


Check the bottom of the drain tube (tube connected to the bottom center of the bottom tray). Does water freely flow out the bottom end of 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 may be clogged with hardwater minerals or other material.

Also, if the humidifier has not been used in a long while it's possible a spider has take up residence by spinning a web in the bottom tray or tube. Tell the spider to find a new home.

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

And lastly, is the unit installed properly, parallel to the ground? If tilted, water flowing through the unit may catch the sides and flow out where it should not.

Water leak


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.
