Question about Maytag M7DH45B2A Dehumidifier
This will get you your manuel

In addition to checking the connection point, as johnsoncd mentioned, you should also make sure your drain hose is not plugged. I just discovered today that the drain hose hooked to my Maytag M7DH45B2A was plugged. A couple of months ago, my bucket kept filling up, as was posted by Hurlingboy. There is an overflow hole that, I presume when the dehumidifier is level, causes the water to go into the bucket if the drain is plugged. I believe I may have repositioned the unit, because instead of filling the bucket, it started to leak on the shelf that it sits on. It occurred to me that the drain hose might have been plugged, which ended up being the case.

I have the same problem and discovered there is also a small hole in the plastic collection tray at the right end of the tray. You can see it when you remove the filter screen and use a flashlight to look inside and to the right of the filter slot, or you see it when you remove the collection tank and look up at the plastic tray from the bottom (it's right above where the float is in the collection tank). Maybe it is an overflow opening that allows water to escape into the tank if the hose becomes plugged. I suspect that if the unit is sitting on a floor that slopes down to toward the right side of the unit, this small hole will constantly drip water into the collection tank. I see three solutions: (1) change the orientation of the dehumidifier, so it slopes to the left (2) place thin shims under the right side wheels of the unit, so it slopes to the left (3) fill the small hole with silicon rubber or a small cork. (By the way, instead of using the hose adapter and a hose, you can also use 1/2" inside diameter clear pvc hose that you buy by the foot at a hardware; it's a snug fit but it works great.

I tried several different sizes of soft and hard tubing and finally found one that works. The attached tubing has to be absolutely snug around the spout and when it arcs slightly downward, the water goes into it rather than the bucket. I attached garden hose to this 3 inch length of tubing. It took me at least ten tries before I found the right size and angle. At last!

Did you check to see if the adapter that you connected the hose to is pushed all the way into the unit so it covers up the smaller tube that allows the water to drip into the water collection bucket? The other end of the tube does not screw into anything it just slides over the smaller tube.

Thanks so much, solutions work. Maytag wants nothing to do with this machine.

Try using a cue tip swap to clean-out the connection point inside the unit. If you can remove the front cover of the unit you can also clean out the little drain tube on the other end. Reconnect your hose and it should work. If not your drain pan might need to be replaced and it's not worth the effort - get a new unit.

Thanks for pointing out the Fedders link! I saw a Fedders tag on the back of the unit but also the Maytag brand. Maytag's site certainly doesn't acknowledge this unit's existence.
