Clean off the coils in the back and the filter (if it has one) and fins in the front (you may have to remove the case). if the front is not warm and the coils are not cold or they are iced up, you have low refrigerant.

Why would the system keep running, all the time, filling up bucket, then leaking onto floor? What is my next step?


There is supposed to be an auto-shutoff float in the bucket to prevent overfilling of the bucket. You have either removed it or it is defective. The fact that it runs constantly has more to do with the humidity and the setting that you have the unit set to, Obviously there is adequate humidity in the space or the bucket would not fill. You need to look for, find, and repair the shut-off float, or, if possible, some units allow you to connect a drain hose either to the bucket or directly to the unit to drain the water to a drain. If you choose this option, remember that the hose must remain lower than the top of the bucket or it will not drain properly and the bucket will still overflow.

When full bucket light comes on water is emptied and bucket put back in position. Fan will start and then the full bucket light comes back on beeps and shuts off.


You have to be sure bucket is replaced exactly where it should go or the bucket will hold the switch in, thinking it is full. If you have a floor drain close by,remove the bucket and set the dehumidifier over or next to drain so water will go down it,then you don't worry about bucket getting full.If it doesn't run with bucket off, maybe defective switch. unhook wires to the bucket switch and hook or tape together,if dehumidifier runs then switch is bad. UNPLUG FROM OUTLET BEFORE DOING THIS. IF YOU DON'T UNDERSTAND ELECTRICITY GET QUALIFIED HELP!!

My fan runs but the compressor does not start on my whirlpool model ad25bsro so no water is collected.


1st ck that the bucket full light is not on , reguardless if bucket is m/t and in place , if light is on then the float sensor inside bucket container needs looked at , if no light is seen then it's common on new units to run the circulation fan all the time , and cycle the compressor on the humidistat's setting , reverify what the settings are for your room , std setting is 70%rH for a home , also a seperate meter to indicate %rh might help to determine if your unit is working properly (there not expensive) it migtht be that your room is dry enough and unit is not calling for water removal

I am not sure of the exact model number, but the unit is rated for 70 pints. It shutdowns and lights the full bucket lamp, but the bucket is not full (there is a hose attached). I dis-assembled the unit...


The problem is that the hose connection tube that the hose is connected to, is clogged. That's the reason water was going to the bucket and the full bucket sensor was shutting the unit OFF

To unclog the tube, you will need an 18" long Plastic Zip Tie or something similar (NO Wire Coat Hangers, though) that is appropriately sized to fit into the hole. Before doing anything, Turn the Master ON/OFF Switch to OFF and unplug the unit.

Carefully insert the Zip Tie into the hose connection hole/tubing and continue to gently push it in, until it reaches the bend in the tubing. You will need to gingerly work past this bend, until it bottoms out or you run out of usable Zip Tie. Now, slowly remove it, while rotating it. This will dislodge the clog. As the Zip Tie is almost totally removed, be prepared for some water to follow.

The above should solve your problem. Will you still need the wiring schematic to reconnect the bucket safety switch? If so, please let me know.

My dehumidifier compressor runs and then shuts off, then runs and shuts off, continuously. The fan continues to run. It seems to be pulling water, though it's hard to tell how much because I have a...


Part of the problem may be that you have the humidity level set to high. The fan runs constantly to move the air around. When the unit senses a humidity level higher than what you have it set for, the compressor turns ON. Once it's ON, if the humidity level is short lived, it turns OFF.

Try setting the humidity level to the lowest possible setting. Usually, that 45%. If the humidity level in you home is higher than that, the compressor should turn ON and run until either the bucket is full or the humidity level reaches 45%. If this doesn't solve the problem, turn the Master ON/OFF Switch to OFF and unplug the unit from the wall outlet for 12-15 minutes. Plug the unit bakc in, turn the Master ON/OFF Switch to ON and set the humidity level at it's lowest setting. Allow the unit to run until it cuts OFF and check the bucket for water. Hopefully that 12-15 minute time out allowed the unit to reset itself.

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

The dehumidifier will not run. It has power to the control panel but the "bucket full" light is flashing RED. We have a hose hooked up to the unit to drain the water and we have check the bucket...


Generally, the buckets on these units can be a little finicky. Especially, if the bucket is not installed properly. In other words, if the bucket doesn't trip the safety switch, when it's out in place and the "bucket full" indicator will remain on and the unit will not run. I suspect the hose attached to the bucket may have gotten the bucket slightly out of place and it's not triggering the safety switch. Turn the unit off, and reinstall the bucket,. Then turn the unit back ON. Make sure there is a little slack in the hose from the unit to the where ever you're draining the water to. In other words, the hose should not be pulling on the bucket.

As I said, they can be a little finicky, so be patient reinstalling the bucket. As it may take several tries, before you get it right.

Hope this helps solve the problem.

Model 501D(had the wrong model number before) When I turn the unit on where the humidity is set there is a code CO 01. Unable to find my manual. the unit starts then turns off.


Hello,

I will advice you check the water bucket to see if it is full and empty the bucket in a sink if needed. GE dehumidifiers have a safety feature that shuts down the device when the water in the bucket reaches a certain level.
Install the bucket correctly in the unit by hooking the slots on the bucket on the posts on the back of the device. The dehumidifier will not run if the bucket is not properly setup in the device.
Take care.

Runs and allows you to adjust settings, but no water ever fills bucket


Hi,

First, make sure the humidistat isn't set too high by adjusting it to the lowest humidity setting and running it again. Next, test the dehumidifier by placing it in a closed bathroom with a hot shower running. If you don't see water collecting in the unit after several minutes, turn the unit off and clean all dehumidifier filters and coils. If, after adjusting the settings and cleaning the unit, you still don't see water collecting, you may have a refrigeration issue. This situation will have to be addressed by a qualified technician.

Take care.
