Runs but no water in bucket

The motor runs, and the humidity sensor seems fine but no water is being produced. This model HD456 is less than 3 years old.

    My Haier HD456 dehumidifier won't work. The fan, the solenoid and humidity setting all work, but no water in the bucket. Cleaning a small hose "between the solenoid and the humidifier" was suggested but where do I find this hose and how do I get access to it? Do I have to dissassemble the whole cabinet?

  • brochures620 Jun 04, 2010

    I got my Haier HD456 out of the cabinet. Blower runs, seems like the thermostat/sensor work. Just no water in the bucket. What tube am I looking for that is plugged up? Lots of tubes in there, how do I identify the final discharge tube so I can try to clean it out?

  • brochures620 Jun 04, 2010

    Don't think I got an answer I can use. Looks like I buy another 200.00 dehumidifier less than 3 years after the Haier HD456 purchase. 3 years and done? Unacceptable, and infuriating.

click this link directly to check the connection of hose in dehumidifiersNo water in the bucket:--
If you do not hear the compressor running and the unit says that the humidity in the room is higher then the setting, then you have a problem with your dehumidifier.

A few things that can cause this are:

The circuit board relay has gone bad…replacement of this board will often cost more then a new unit. This also is a very common problem with many dehumidification units.
The compressor has failed…if you hear a buzz for a few seconds, every few minutes, then you have a bad compressor or at least bad start components on the compressor. Either way it again is a costly repair.
If the compressor is running and the coils are not getting cold then you have a refrigeration system leak. Recharging or fixing these units is very difficult and is another costly venture compared to the price of a new dehumidifier.
If the compressor is running but the fan is not, this also will cause low water production and continual freezing of the coil.
If the compressor and the fan are running but the coil is totally blocked then you will get no water production. Air needs to be continually moved over the cold coil to get the water out of the air.
If nothing is running, then you may also have a control board failure. Or the humidity sensor orhumidistat has gone bad which tells the machine to run. If the sensor says that the humidity is low enough then it will never run.
Also if nothing is running check the float switch or the bucket switch. Many of these switches are very touchy and if you do not have the bucket in place just exactly right it will not trip the switch to allow the unit to run. These switches often are more fragile then they should be and break easily. The good thing is that when available they are easy to replace and relatively inexpensive.

    3 years to failure is pretty bad. All the internals look new, motors and sensors seem to work. Some problem that I can't fix, so I guess it goes into the trash. Any recommendation on a long lasting 45pint 200.00 dehumifidier that will give me a decent lifespan?

One of my friend had the same problem and thought the solenoid valve was bad and was about to spend $80 for a new one. Then he took the short pipe (between the solenoid valve and humidifier) off and he found that the orifice was plugged. I used a sewing pin and cleared out the hole. Problem was solved. I usually have to clean the orifice in the fall when I turn the heat on for the first time.

    Where is the solenoid and this hose? Do I have to take the whole cabinet apart?

  • Arjun Komath Jun 04, 2010

    Yes

  • brochures620 Jun 04, 2010

    Arjun - I can't find the right hose to try to clean out. Can you describe where it is and what it looks like? There is lots of tubing in this unit

My dehumidier is not pulling any water into the bucket. Runs fine. About 1 year old.


If the unit is not pulling water into the bucket its probably not that humid in that area anymore. If it aint broke dont fix it.

Didn't LG produce some bad Humidifiers several years ago and have a recall on not working units? I recall reading this in Consumers Reports. I bought one back then and it has not produced a drop of...


If has not produced a drop of water for several years, then it's not working properly. But, this may be a case of setting the humidity level to high. In other words, if you set it at 70% or Maximum, that's the humidity level that it will maintain, not remove. To remove humidity, the level must be set low (35% or Minimum).

To test the unit, based on what I just said, place it in the bathroom, set the level as low as possible and turn the shower on medium hot. Do Not turn the bathroom exhaust fan ON. As you leave, close the bathroom door. Return in 15 minutes, turn the shower OFF and check the bucket water collected. If there's any water in it, it's working fine. It was probably a case of the humidity level being set to high.

Hope this helped you. Please let me know. Thanks.

My Goldstar dehumidifier model DH304 runs,but fails to pick up any water


If the room air is less than the set air, then there is no water in the bucket, because there is almost no humidity in the air. If it is winter, there is likely not enough humidity in the air to have water collect in the bucket. A dehumidifier will only pick up humidity out of warm air. If you are running a dehumidifier in your basement in the winter, the room may be damp, but too cold for the dehumidifier to pull out the humidity. Try running the unit in the bathroom after having a hot shower without the bathroom fan on. If working correctly the unit should draw water.

Other things that can cause problems: 1.Check to see if the air filter is dirty and/or blocked. 2. The room temperature might be too low, (below 60 degrees Fahrenheit ) 3. Check to make sure that there is no obstruction to the unit that might be causing poor airflow circulation.

Hope this helps you to troubleshoot & solve the problem.

UNIT TURNS ON AND RUNS BUT NO WATER IS IN THE RESEVOIR BUCKET TO EMPTY, IT RUNS PERFECT BUT JUST DOES COLLECT ANY WATER AT ALL. UNIT IS ALMOST BRAND NEW, EVERYTHING STILL LOOKS NEW BUT WON'T COLLECT ANY...


The air intake filter may need cleaning. Also, check the humidity setting. You may have it set to low. In addition, it wouldn't hurt to check the drain tube or drain hole (whichever one your unit has) that's just above the bucket. You'll see it once you remove the bucket. It may be clogged and is not allowing the water to drain properly. Using a 18" long plastic Zip Tie or something similar (No wire coat hangers) that will comfortably fit into the hole ... Carefully and gently run it as far as you can into the drain hole or tube. The tricky part is when you reach the bend in the tube. So, tread carefully. Once you have it inserted as far possible, as you rotate the Zip Tie, slowly pull it out. Rotating it, will loosen any debris. Be prepared for water to follow.

If none of the above solves the problem, the compressor in the dehumidifier may be low on refrigerant gas and will need to be recharged.

Hope this helps you troubleshoot and solve the problem.

The dehumidifier runs all day but there is only a little water being produced. We have humidity set at 35%, and the actual readings are much higher. This is only a year or so old. The last machine worked...


coolant may be low - warranty should be 5 years

If the room temperature is close to 60, the coils may be frozen (completely encased in ice). If this is the case, move it where the water can drain off - about 1 gallon which may NOT run into the drain bucket.
I out mine over the floor drain.
Turn off and it will defrost over night.
Only specially made dehumidifiers work below a room temp of 60 degrees (the temp of a basement in winter).
Does it need to be running? A digital humidity sensor from Radio Shack is cheap and may tell you the humidity is OK - only 50% or less.

No water in the bucket


You most likely have a freon leak, or the compressor is not running. When the machine first turns on you should be able to see if the compressor is running or if it is just the fan. If the compressor is not running it does have a start devise and a relay on it that can be replaced. If the compressor is bad, most units have a 5 year warranty on the compressor, so contact the manufacturer for warranty service. If the compressor is running you have a freon leak, and it would need to be found, repaired and the freon replaced. This is a large repair, estimated charge for a leak repair would be around $149.99 The reason is the long time it takes to find the leak, and all the parts needed. Drier, valve, freon, etc.. Good luck, and I hope it is only the relay. You can get those relitively inexpencively. 3 in 1 kits are also good for a hard to start compressor. They give the compressor a little more kick to start it. They are about $28.00 and easy to install once you are to the compressor. I hope this will FixYa.

Running but not collecting water...


Dehumidifiers have only a few components, and operate on the same principle as a refrigerator, freezer, or air-conditioner.
Components Residential dehumidifiers have a cooling system made up of these primary components:

  • The compressor is the quiet motor (engine) of the cooling system. It's the black, football-size component at the bottom of your dehumidifier. The compressor runs as long as the dehumidifier humidistat (the humidity-sensor) calls for a reduction in the humidity.

  • The condenser is a series of finned tubes, similar to a radiator. It's usually near the circulating fan.

  • The evaporator is located near the back of the dehumidifier, right above the water-collection container. It also resembles a radiator or a coiled-up set of tubes. When the dehumidifier's humidistat senses increased humidity, it cycles on, which starts the compressor and circulating fan.

  • The circulating fan circulates the air over the evaporator and condenser coils.

Principle When the unit runs, the circulating fan and compressor also run. The fan continually draws room air over the evaporator coils, which are cold, and then over the condenser coils, which are warm. Because the evaporator coils are cold, the moisture in the room collects on them--just as the outside of a glass of icy liquid "sweats" on a warm, humid day. When the moisture on the coils increases, it drips off of the coils into the collection container.

The air then flows over the warm condenser coils and out into the room. This process removes water from the air and, because of the heat from the fan motor and compressor motor, the exiting air is somewhat warmer, as well as dryer.

Running but not collecting water...


Sorry to be vague in advance. I am a bit confused as to the compressor seems to be running bit. If the unit is on you should hear the compressor making a continuous noise. What you have described over a relay going click every fifteen secs could be the compressor overload / relay. If it is then the compressor is trying to start hence the dimming lights. Either way I would suggest one of two scenarios either the compressor is faulty or cannot start due to the relay or the unit is short of gas. Eiher way not a good scenario. I would suggest a tech to confirm or spend the money towards a new unit. Hope this helps.

Runs for a couple of minutes and then stops


Try cleaning out the air filter using cold water. I did not even know the unit had one until I had the same problem. Pull out the bucket. The filter is located where the front top edge of the bucket would be located if it were in the instrument. Remove it by pulling straight down. It may be taped to the instrument for shipping purposes. According to the manual, this should be done every month. I have had the machine since Katrina and this is the first time I have had a problem. Hope this helps.
