Mine dried out too. I could not find where to get the rubber valve seal for the tanks. Holmes does not list the part and when I called the rep told me they didid not stock the part. I solved my problem by purchasing thin rubber washers from Lowe's. They are 3/16 X 1 1/4 X 1/16 thick. The 3/16 hole in the center "snaps" on over the end of the plastic plunger just like the original. I had to trim the outside diameter with scissors to about 1" or using the old ones as a guide. Cost me $0.67

after scouring the INTERNET AND FINDING PLENTY OF SITES THAT WOULD SELL ME THE WHOLE CAP FOR 24.00. I MAD MINE USING SOMETHING FROM ace hardware THAT COST 2.50 Small suction cups with the hook [CDBL-7500S11] PART NUMBER 7500 .CAN BE MODIFIED INTO MAKING YOUR OWN GASKET. IT WORKED FOR ME ..REMOVE HOOK FROM SMALL SUCTION CUP. cut off nib with sharp pair of scissors. THEN DRILL HOLE THROUGH CENTER OF CUP WITH 7/64 DRILL BIT. re insert plunger part of cap through cap with spring and re- attach suction cup instead of gasket. MINE WORKS FINE ON A HOLMES 3700 woodinvirginia

The humidifier has a float valve in it much like a toilet tank does. If the water gets to low, the float valve should allow more water to enter the tank automatically. When it reaches the proper level, the float valve stops the water. The water line (either copper or plastic) coming into the humidifier should have a shutoff valve on it. Make sure that it is turned on.

because no one else posted the site, heres the pdf

you check at local hardware stores. or if your in canada check with canadian tire. if nobody has it locally. you might have to call the manufacturer to order it directly from them.

well since you just purchased this item, you should be able to return it for exchange, and it should still be under warranty, but if thats not doable, then it sounds to me like its a O-ring that is bad if the tanks are removable, best bet though is to exchange it, look at your home owners paperwork, to see about the warranty, more than likely your covered, hope that helped,

Either you have no wick/filters or they are installed incorrectly. Tanks should empty within hours.

You really have an mineral problem. I have pretty much same here. I only use bottle water that comes in gallon size from grocery. Ot is the only way I have found other than constand cleaners or a water softener. Good luck

If the water has been sitting in the reservoir for days without use, it may develop a film on the ultrasonic element which inhibits the creation of the mist to come out the top of your humidifier. I would lift off the tank and empty the reservoir. Then VERY GENTLY with a piece of paper towel, wipe the ultrasonic element (looks like a disk the size of a quarter at the bottom of the reservoir) to clean off any film. Then replace the tank and let the reservoir fill up the tank and try it again. Good luck thebqe
