I have a this humidifier, i got it from a friend. i dont think it is missing any parts, but the tank leaks, it will not hold water at all, how can i fix this.
Check if the cap has a gasket or o-ring and is not worn. There are two designs for this model. The older model has the fill cap and valve together. The new design the fill cap and valve are at different locations. The new design has no hole in the bottom of the unit.
You can fixed the problem using a 1-1/2 inch washer for brass tubular found in the plumbing isles in HD or L. The rubber washer is 1 or 2 mm smaller then the grooves in the fill/valve cap. You can stretch the washer and it will fit perfectly in the grooves. When putting the fill/valve cap back with the washer, it will be tighter then before. Firmly turn and you should not have any leaks and make sure unit is level. You can plug the hole because the new design does not have a hole in the bottom of the unit.
I had the same problem. Turned out to be a bad seal on the cap. I found a customer service phone number for Vicks and they are sending a new cap, at my cost of $4. If I figure out where I found the number, I'll add it to this comment.
18004770457 is the number

I just ordered my replacement tank from kaz.com. Search using the model number and find the tank. I got it for $12....

I have had this problem for about and year and never had any problems. It started leaking yesterday. I turned it over and noticed that it has a hole in the bottom of the unit. The hole is uniform,so it looks like it has probably alwas been there. i don't think I've lost any parts, like a plug. Does anyone have a manual for this product?
I have the same problem. My humdifier (same model as yours) began leaking suddenly after one year of ownership. I just noticed the hole too. I think that the valve at the bottom of the tank is faulty and causing water to stream into the pan. Like you, I don't know why that hole is there.
I have the manual but it does not address this issue. I have scoured the internet looking for a solution.
My previous humidifier needed to have it's filter changed occasionally, but "never" leaked. The only reason I got a new humidifier was because the old one lasted so long, ten years, that they didn't even manufacture filters for it anymore. What a waste of money purchasing this was. It also has absolutely nothing wrong wt the rubber gasket, and is only two weeks old. the unit simply is badly designed. The reason I know it's not the gasket, is because it won't leak when lifting the container into the air. Although it didn't leak when I first placed it into the housing last night, I woke up to a stream of water everywhere this morning. Although it didn't when I first placed it into the housing last night, and it destroyed my good wood floors. It now leaks (gushes) until the entire the entire unit is empty, 1.2 gallons, in only about 3 minutes. I timed it in the bathtub. This humidifier is only two weeks old. I'm glad that I have Liberty Mutual home owners insurance. They told me that you should expect a call from them soon.
