Drain hose not working

After working for about 1 year, the drain hose has suddenly stopped working. It is now insisting on filling the reservoir instead. I've checked the hose and outlet for blockages but found none. Any ideas as to what could be causing this?? cant locate my owners manual. Do I need a special connector for a drain hose as a regular garden hose is to large for the rear drain Tks

Re: drain hose not working

Hi, had the same problem. Not a glogging one. I have the model DDR503H. If it is insisting on filling the reservoir, it is because you haven't put the cap you removed from de back of the unit to plug the hose on the tank water exit. You have to first remove the tank and on the roof of this space, you will see the water tank exit where you can screw the cap removed from the back. You place back the tank into the unit and now the water won't have other choice then leak thru the hose. Also. to clean up the filter, I don't need to unscrew the top cover. I just remove the tank and on the roof of the space, there is a grey handle with arrows on it and I just pulled down, it comes out and you can then clean it up.

Hope this help,

Re: drain hose not working

I have essentially the same model which is, I must say, very poorly designed. It is still possible and likely that the drain hose is clogged with dust build-up within the tray (which is inside the unit and inaccessible without taking the cover off).

I don't use the drain hose, but was noticing mine was leaking all over the floor without the reservoir being even half full. I tried to clean it a few times but the problem kept coming back. Eventually I took the thing apart and discovered that the tray was so clogged up with dust that both the drain hose line was clogged (even though I don't use it) and the drain into the reservoir. I took it out on the deck and flushed the thing out with a hose.

Next time I won't have to take everything apart. Just remove the cover and you'll see the tray in the front over the reservoir, tucked in under the coil assembly. Just stick a hose in there and blast all the dust out.

I expect that I'll have to do this at least annually (our unit is in the laundry room so it may be clogging up with lint quicker than one placed elsewhere).

Trouble with disposing of water. I have it hitched up with hose, but humidifier insists on filling the interior bucket. Help please

For the hose to work the unit must be elevated somehow so that the bucket will not fill. Or somehow the unit must be higher than the end of the hose. If you put the hose down an open floor drain that should suffice.

Hose connected but not draining and bucket filling

I am also an air conditioning tech, with same problem and same soleus dehumidifier problem. you must remove the plug and install the drain line hose adapter. Hose must lay flat and have no "hills" for water to drain. With this done pull your drain pan out and set aside. look under right side facing the dehumidifier and you will see a small spout. Has a lip like a little tea pot. Plug that spout. I used a foam ear plug used in work shops. Now give the front of dehumidifier a slight rise on front wheels about the thickness of a pies of cardboard 1/8 to 3/16 of an inch. Now put drain pan back in an start up. The problem is the drain pan was made with very little differance in pitch between the the hose drain and the bucket drain. Remember to check your drain hose periodically and the air filter also. Good luck

Hose line is no longer draining the unit, bucket fills instead

Sounds like the connector hoae came off inside the machine . Look up inside the machine where the bucket would go and you should see where the hose attaches to the condensate drain . It might have pulled off .

Change my dehumidifier from draining by hose, to reservoir

I don't have the exact dehumidifier as yours, but on mine it's as simple as removing the hose, then the water fills the reservoir. Does it look like yours will do the same? If so, the hose fitting is also a sensor that will shut the unit off when it is full to avoid leaking onto the floor.

Why does my bucket fill when I have connected a continuous feed hose for discharge? The hose does not seem to empty the humidifier.

Check to make sure the drain hole connection on the Dehumidifer's reservoir, that you have the hose hooked to, isn't plugged.

Also, you might want to see if the hose connection on the reservoir, still has the "knock out plug" still in place. Look at the hose connection on the reservoir, and if you can't see through it, or put a screwdriver through it, you need to punch it out the middle with a screwdriver. Open up the hole as much as you can so it will drain into and through your hose.

Check your hose also, as it might be plugged, disconnect it and blow through one end to make sure the water can flow through it.

Those are the only three things that could be preventing it from draining out the reservoir, through the hose connection, and through the hose to your drain.

Hope you find this Very Helpful and best regards!

Water goes in reservoir, not thru hose to sump pump, leaking

blow some air thru the discharge line,, thats all it is the line is clogged, if the pan is filling with water, it is working but they do get clogged with dust and lint in the air,,

Haier 30 pint dehumidifier continuous drain problem.

Many just attach the hose at the reservoir; from your description, Haier apparently has a separate location. Check that the point that the hose attaches has an opening (many don't, they expect you to drill it). It should then drain through gravity. Check to make sure that no part of the drain hose is higher than the bottom of the reservoir, otherwise it can't drain. It won't siphon because each time the the tank empties, the suction is broken and the siphoning can't continue.

My direct drain doesn't work anymore

I fixed the same problem, finally. At first it was sufficient to clean the outside hose (it was filled with a **** builtup). Then it stopped working again. I decided to open the unit and see how easy it is to clean the inside drain hose. It is very easy. Once you unscrew the back panel (8 screws total if i remember correctly) you can access the back and you see the drain hose that connects to the drain outlet. To remove it and clean it, you will have to unfasten the big capacitor (3 screws). Then, remove the hose and clean it (mine was full of that same **** stuff). Reinstall - you will need a tie wrap to connect the hose at the top, as it is from the factory. Very easy operation and now the dehumidifier is draining again.
