Dehumidifier isn't not removing humidity. Fan and lights are working, but the water container remains empty. It is not pulling water from air. I think that the heating element may not be working.

Has been running fine. my daughter emptied it yesterday morning and didn't put the catch container back in the machine properly and a red light (small round) on top left of machine was on when I went...

Actually, the fan shouldn't be working if the water bucket is not installed properly. So, I believe it's more of a case of the electronic controls need to be reset.

To accomplish this, turn the Master ON/OFF Switch to OFF and unplug the unit for 15 minutes.
After the time as elapsed, plug the unit in and turn the Master ON/OFF Switch to ON. The Bucket Full light should not, now be ON. And the unit can function as it should, after you reset the controls for maximum humidity extraction (32 - 35%).

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

E1 display humidied is at 98% flashing blue light

That's indicating the the humidity level you have it set on is, set to high to remove humidity in the air. Turn the unit OFF and unplug it from the wall. Remove the water collection bucket and empty is if there's any water in it. Wait 10 minutes and remove the air intake filter and clean it, if necessary. Then, plug the unit back in and turn the Master ON/OFF Switch to ON. Lower the humidity extraction level to 32 - 35%. The unit should start up and operate as it should.

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

FAN AND COMPRESSOR START. HUMIDITY SET AT 30, ALWAYS RUNS. NO WATER IS CONDENSED. PAIL STAYS EMPTY. CLEANED FRONT AND BACK OF COILS, REALLY ONLY FINS,CAN'T GET TO COILS WITHOUT HAVING TO DO A...

Rather than have you disassemble the cabinet to get to the coils, I want you to do an "At Home Test".

Move the dehumidifier to a bathroom that has a shower. Plug it in, Turn it ON and set the humidity level at 30%. Turn the shower on to medium hot (enough to generate some steam. Do Not turn On the bathroom exhaust fan. As you leave the bathroom close the door. Wait 15 minutes and return to the bathroom. Turn the shower OFF and inspect the unit's water collection bucket for water. If you find any, the unit is working as it should. If you don't find any water, it may be that the humidity sensor has failed or the air intake filter is clogged. In which case, remove the filter and clean it. If it's the sensor, unless you are really DIY savy, I'd recommend buying a new dehumidifier. As finding the part (your unit was made by Fedders), the cost of the part and the labor involved, to me, out ways repairing it.

Now, on the positive side ... If you saw water in the bucket after the bathroom test. It may simply be, that at this time, there is not enough humidity in the room air (even at 30%) to trigger the sensor. If the unit is in a basement, the air temp (60 degrees or lower) will affect it. As the temperature at floor level (where the unit is) is 5 to 8 degrees colder than the air temperature. Dehumidifiers don't work well in cold temperatures.

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

The dehumidifier runs, cycles on and off, but there is almost no water in the receptacle. I haven't had to empty it since it started cycling on & off this season. I usually have to empty it at...

You may have the humidity setting to high. Try lowering it to 45%. Or if yours doesn't have an LED Screen, set it for minimum. Also, check and clean the air intake filter, if you haven't already. Keep in mind, most dehumidifiers have a fan that may seem to run constantly, but the compressor doesn't turn ON. The fan is circulating air, in a effort to detect humidity levels that are higher than what you have the humidity removal set on.

Hope this helped you.

Dehumidifier does not see to be collecting water, fan is running but no water from hose

It very well maybe, that you have the humidity removal set to high and it's not sensing any humidity to remove. For example, if you have it set on 65 - 70%, that's not how much humidity it's going to remove. It's the level of humidity it's going to maintain in your home. To remove moisture/humidity, the setting should be low, like 45%. As far as the fan running ... many units are designed that way, in an effort to help keep the air circulating and also to defrost the cools.

If you want to test the unit, to see if it's working properly. Place the dehumidifier in the bathroom and set it at 50%. Turn the shower ON and let it run for 20 minutes with the bathroom door closed and without the exhaust fan running. And check on it after 20 minutes. More than likely, there' will be water in the bucket.

Also, there's routine maintenance that should be performed regularly. Clean the air intake filter, clean and wipe off the the compressor coolant coils, and check for clogs in the drain line of the unit.

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

Unit runs but doesn't collect water and there is a lot of water in the basement. Have had dehumidifier for two weeks and was working well before.

Keep in mind, that a dehumidifier only draws humidity from the air, if the level of humidity is higher than what the controls are set on. For instance, if you have the dehumidifier set on 65 to 70%, that's a high level of humidity to maintain in a house. If you have it set for 35 or 45%, that's a low level of humidity to maintain in a house. Which, generally is what you want to maintain in the hot, humid summer months. Also, it's not uncommon on some dehumidifiers for the fan to almost run constantly. It's designed to keep the air moving, in a effort to detect when the humidity level rises.

Also, a dirty air intake filter makes the unit strain to keep up and can't take in moisture as it should. So, if you haven't cleaned the filter no is the time to check and clean it. And while your at it, clean the cooling coils too. Since it sounds like this unit has been working hard for 2 weeks.

The easiest and best way to test a dehumidifier at home, to see if it's working properly. Is to place it in the bathroom and turn the shower ON and don't operate the bathroom's exhaust fan. Set the humidity level low (45%), turn the unit ON and close the door when you leave. Wait 15 to 25 minutes and check the water collection bucket. If there's water in it, it's working as it should.

For more information on the proper operation of a dehumidifier, go to the Tips section of Fixya and look up "Taking the confusion out operating a dehumidifier".

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

Haier dehumidifier will turn on but does not collect water.

hello. If your dehumidifier doesn't seem to run often but the humidity in the room is high, try adjusting the humidistat control on the dehumidifier to a dryer setting. If the dehumidifier seems to run constantly, but there's little or no water in the container, there may be a problem in the refrigeration system. Try cleaning the unit. If that doesn't work, you can't repair the refrigeration system yourself, you need a qualified appliance repair technician to do that.

Dehumidifier doesn't draw in water (humidity).

It may be too cool in the basement for it to work. Mine doesn't work if its 67 or below. Take it upstairs and see if it works there, where it is warmer.

FULL LIGHT FLASHES

An automatic overflow switch and Container “Full” indicator light are provided to turn the
dehumidifier off before the container overflows. When the indicator light on the control panel
glows, the water container must be emptied. If the light remains on and the dehumidifier does
not begin to operate make sure the float is attached to the water container.


When the condensate water container is full, the indicator lights up.
1. Turn the power off before removing container. Wait 3 minutes for
any remaining water to drain into the condensate container.
2. Tilt the container forward then lift carefully by the handle.
3. Empty and gently re-insert the container.
Important:This water is not suitable for drinking.

Please rate and god bless:)
