The dehumidifier does not draw any water from the air

The humidifier is set on 40%, the humidity is 60, the machine runs but does not take any water from the air and the humitity stays at 60. What is wrong? My dehumidifier is running smoothly but is not collecting water. It's set at 40 but will not come down below 60. I cleaned the air filter. I'm not sure what else to do.

SOURCE: Dehumidifier

Most dehumidifiers have a "Frost Guard" mounted on the condensor coil. If frost accumulates on the condensor coil the frost guard turns the compressor off until the frost melts, then comes back on again. For the dehumidifier to work properly, the surrounding (ambient), temperature must be higher than 65 degress. This temperature allows the moisture in the air to condense on the coils and drip into the reservoir without freezing up on the condensor coil. Also, if the humidity is too low, (below 45%), the same condition will occur. So it will help to keep the parameters in mind when you have this issue.

Thank you for your allowing me to advise you on this issue.

SOURCE: Dehumidifier Does Not Collect Water

Hi,
A dehumidifier is just a refrigerating machine with it's shirt hanging out and there is not much in the way of serviceable parts inside.
If the compressor runs - the throbbing sound - and it doesn't collect water then either the intake filter screen is totally clogged with fluff or the compressor has leaked it's gas away, in which case it might run continuously and get hot to no good effect.

If it doesn't run then it may be that the motor capacitor has failed, but that can soon lead to the compressor motor cooking itself; leaving you with an expensive doorstop.

The one thing you might get checked is the "bucket full" switch. There will be a floating part on the bucket which rises up when the bucket fills and eventually makes contact with another part which is connected to a small switch. If that switch has failed you might be lucky and get an inexpensive repair job done.

If these suggestions do help you solve the problem, please give my reply a suitable rating. If they do not, please add a comment with more details so I can try to help you further.
Cheers, D

SOURCE: The dehumidifier is running but very little water

I have the same problem, just started it after not using it for the winter and it runs and runs and no water. I believe the coolant has leaked from the sealed system and there is nothing you can do. I've had it for 1 year and it has a 5 year warranty. I know from experience, this is the 3rd dehumidifier that I have had this problem with, all different brands. Call for service, I am betting you have not had it very long.

Lcated in basement, quite humid; humidifier runs but not drawing any moisture into the container.


There are 5 basic, yet solvable reasons for what you described. Please pay particular attention to numbers 1, 2 & 5..

1. The humidity extraction level is set to HIGH. Lower it to 32-35%. If you have a
mechanical/manual unit, set the control knob to Maximum.

2. Air intake filter is dirty or clogged. Turn unit OFF, & Unplug the
Unit, before removing to inspect & clean it, if necessary. If washed,
allow filter to completely dry before reinstalling. DO NOT operate
the unit without the filter.

3. Obstructed air flow. Maintain a minimum of 12 to 18" of clear air
space around the entire unit.

4. Cooling coils are dirty and need to be cleaned. Use warm water & dish washing liquid to
clean the coils. Rinse and wipe dry. Apply a light coating of WD40 to the coils.

5. Ambient air temperature at floor level is between 40 - 60 degrees.
dehumidifiers do not work well between those temperatures
(Unless, you have a Low Temp Unit). This applies mainly to
where the air temperature at floor level is colder than at shoulder
level
in basement applications. Raising the unit up off the floor,
onto a sturdy table, counter top, etc, that can handle the weight
of the unit, plus a full tank of water, will usually resolve this
problem.

If none of the above solves the problem, it may be a case of the compressor needs to be recharged with refrigerant gas or that the humidity condenser sensor has failed. These things usually occur in units that are 5 years old or older. It's rare in a unit younger than that. But, it can happen.

I hope this helps to your troubleshoot & solve the problem. Thanks for choosing FixYa.

Whirlpool dehumidifier ad35dssi runs, but doesn't collect any water, even in a wet area. Have cleaned filters, no luck.


Glad to hear that you thought to clean the filter, as that would have been one of my suggestions. Because, it's the most overlooked.

But, there is another one that equally overlooked and is probably the number cause of your humidifiers problem. The humidity extraction level is set to HIGH. Lower it to 32 - 35%. If your unit does not have an LED Screen readout, set the control on MINIMAL.

This is what gets confusing about the use of dehumidifiers. They work backwards from what most people think. The lower the setting, the more moisture/humidity is extracted from the house. The higher the setting/numbers, the more humidity remains in the house. The higher setting would be used only in the Winter, because removing all the moisture and humidity will make the house uncomfortable.

If this wet area, you mentioned is a basement. The ambient air temperature at floor level is colder than at chest level and dehumidifiers don't work well in temperatures between 40 & 60 degrees F.
If this is the case, placing the unit up off the floor on a sturdy table, counter, etc that can hold the weight of the unit, plus a full bucket of water will generally solve the problem.

Also, be sure that you're maintaining at least 12" of clear air space on all sides of the unit. If the air flow is obstructed, the unit will run all day and not extract any water.

Hope this helped you troubleshoot and solve the problem. Please let me know. Thanks.

My dehumidifer is not drawing any water, but the fan continues to run.


There are several reasons this may be happening. The 2 primary reasons are the humidity extraction level is set to high. Lower it to 35% . The lower the setting, the more moisture/humidity is extracted from the air. The higher the setting, the less if any moisture. humidity will be extracted from the air.
On most humidifiers the fan runs almost constantly while in operation. The idea is to continually move the air around and when the unit senses a rise in humidity, above what you have it set on, the compressor will turn ON to extract that humidity.

The 2nd thing that causes the problem is a dirty of clogged intake air filter. Which is easily solved by removing and cleaning the filter. Which should be done at least every 2 weeks, while the dehumidifier is in operation.

I said there were 2 reasons. Actually, there is a 3rd. Not enough clear air space all around the dehumidifier. A minimum of 12" should be maintained during operation.

Hope this helped you to troubleshoot and solve the problem. Please let me know. Thanks.

My Kenmore dehumidifier has stopped drawing water from the air to the collection receptical. Fan still runs at high and low speeds.


A couple of things may be happening: The humidity extraction level may be set to high and it can't extract any humidity at that level. Reset/Lower it to 35%. The fans on most dehumidifiers run almost constantly (designed that way) so that it keeps moving the air around. If the sensor picks up a higher humidity level than what it's set to maintain, the compressor will turn ON. This is particularly true, if you operate the unit in continual mode, rather than a timed mode. Also, a dirty or clogged air intake filter, hinders the units ability to remove humidity/moisture.

In addition, operating the unit is ambient air temperature of between 40 & 60 degrees F, causes the unit to struggle to dehumidify the air and the fan to run continuously. Obstructing the air flow around the unit, will also cause it to not function as it should. Maintain a minimum of 12" of free air space around all 4 sides of the unit.

Hope this helps you troubleshoot and solve the problem. Please let me know.

The humidifier is starting and running,but there is no water in the bucket


ayke, this can be caused by several things: The air intake filer is dirty and needs to be removed and cleaned. The humidity level on the unit is set too high and should be lowered to 35%. The air circulation around the unit is obstructed. There should be a minimum of 12" free air space all around the unit. The air temperature in the room is to low for the unit to operate properly. Most dehumidifiers will not work well between 40 and 60 degrees F.

To do an in home test, move the unit to the bathroom, and start it with the humidity level set at 35%. Turn the shower ON hot enough to generate steam. Do Not turn the bathrooms exhaust fan On and close in windows in the bathroom. As you exit the bathroom, close the door. Wait 15 to 20 minutes, before returning to the bathroom. Then open the door and turn the shower OFF. Allow the dehumidifier to continue run for 5 minutes, the check the water collection bucket for any signs of water. If you see any water, the bucket is working as it should.

If you don't find any water in the bucket, the humidity sensor may have failed and/or the compressor needs to be recharged with refrigerant gas.

Hope this helps you to troubleshoot and solve the problem.

Dear Sir , the dehumidifier is running the motor is running, but not sending out any water. I have cleaned the filter.n Any recommendations?


Is it only the fan motor running that you hear? Or is it the compressor motor and the fan motor in combination?

If it's just the fan motor, it running to circulate the air, in an effort to sense humidity in the air, above the level you have the humidifier set on. Speaking of which, you may have the level set higher than what the humidity is in the house and the unit is just maintaining it. 50 to 60% is high, as opposed to 35%, which is what most folks want to maintain in the hot, humid, summer months.

If you want to test the unit, place in the bathroom, turn a hot shower ON, turn the humidifier ON and set it for 45% or minimum if your unit does not have a LED readout screen. Do Not turn the bathroom exhaust fan ON. As you leave the bathroom, close the door and don't return for 20 minutes. When you do, turn the shower OFF and check the humidifiers water collection bucket. If you see any water, the unit is working as it should. If you don't see any water, it's time to replace that unit. I say that because, at best, the parts and labor to repair the unit would be equal to or almost equal to, the price of a new dehumidifier.

Hope this helped you troubleshoot and solve the problem. 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.

I just purchased this humidifier. I set the humidity temperature to 40 and the fan is constantly running but there is no water filling into the bucket. Although the humidity temperature is set to 40 the...


Nicole, some of the packing material may have gotten into the drain tubing or hole and clogged it. Remove the water reservoir and look for a vinyl tube or drain hole in the cavity that the "bucket" came out of. If you can see anything blocking it, carefully remove it. I don't think at this point anything would have gotten any further down the drain tubing. Since this a brand new unit, consult your Owners Manual for directions on how to Troubleshoot this problem. If that fails, it's under warranty. Contact the manufacturer as directed in the Owners Manual.

Hope this helps to get your problem solved.

The current humidity % reads 40% humidity but the room has to be about 60%. I have to set on 35% to get it to pull the water out of the air.


Your machine cannot work when it is frozen ... if the % is as high as you claim and the setting is as you say, if it is not frozen up yet ... it will will be.

Please get a small fan and direct the air flow at the back of your machine ... set it to about 40% and let it run for a while.
