Bucket full light will not go off and unit will not operate (there is no water in the bucket).

    I appreciate the input. However, when I pull out the bucket, the floating mechanism seems to simply be a plastic floating device which seems to operate okay (unless something happens when I put it back in). I also notice a "red" button (almost seems like a reset button) in the back of the device that seems to go together with the plastic floating device?

    Sorry to be such a pain but when you say "the float must be lifted to ensure the bucket slids past it...then it drops into the bucket space." I'm not seeing this; the float is actually part of the bucket (plastic piece attached to the back of the bucket).



    You are correct; did not realize about the rating. Sorry.

The bucket full light is controlled by a manual 'float' switch in the bucket itself
-when the water level rises...it lifts the float ...turns on the light and does not allow the unit to operate because it believes it is full.

It is very common for the 'float' to gets misaligned, hung-up, etc. when you remove and re-insert the bucket. Sometimes the 'chain' gets twisted, turned...which does not allow the float to ...float...rather it is 'hung-up' which indicates it is 'full'...when in fact it is clearly not.

To check this:

  • remove bucket from unit
  • look into the top of the bucket opening to locate the 'float'...generally 2" round plastic ball on a shaft, (or chain)
  • softly cup the float in order to lift this up...with the unit stilll plugged in...to see if the light goes off...this is very likely
  • then be sure that the float mechanism is able to freely 'float' in the space....i.e. you are trying to simulate the impact of rising water levels in the bucket
  • as it rises (in your hand the machine will turn off/light on...as it drops....the light shuts off, allowing the machine to run (when humidity levels demand it)
  • then re-install the bucket....being very careful to lift the float, while you insert it...there is generally a little nack to it...but you quickly learn how to do it easily (I just reach into the space...cup the float...put the bucket on an angle...slide it in....release the float into the bucket...(remove hand)...then finish pushing the bucket into place
-hope this helps

    RE: putting the bucket back in
    -the float must be lifted to ensure the bucket slids past it...then it drops into the bucket space
    -the little red button it what is engaged/pushed when the float arm hits it...this shuts off the machine

My dehumidifier's red light illuminates seconds after turning on the unit even though no water has been collected... it is unusable


Shannon, this is also an indication that the water collection bucket was not reinstalled properly. Turn the unit OFF, unplug the unit and remove the water collection bucket. While it's out, check the top of the bucket for a float valve (if yours is so equipped). As it may be stuck in the UP position. If so, jiggle the arm of the float valve to make it return to the down position. When you reinstall the bucket, be sure that it fit's "squarely" from top to bottom into the bucket holder and makes firm contact with the bucket safety removal switch on the back wall of the bucket holder. The bucket should not tilt down at the bottom when installed properly.

Lug the unit in and turn is ON. If all was checked and done correctly, the bucket full light should not illuminate.

Hope this helped you and thanks for choosing FixYa.

It says it is full and there is no water in there and it will not run because it thinks it is full]


Usually when this occurs, the unit "thinks it's full', because either the water collection bucket is not installed properly or the float valve (if you model has one) in the top of the bucket, is stuck in the "UP' position.

Turn the unit OFF & unplug it. Remove the water collection bucket and check for the float valve. If it's stuck in the UP position, jiggle the handle to make it return to the DOWN position. Then reinstall the bucket, being sure that it fits into it's holder "squarely" from top to bottom and is making firm contact with the Bucket Safety Removal Switch on the rear wall of the bucket holder. If installed properly, the bottom of the bucket should not tilt down at all. Plug the unit in and turn it ON. If everything was done correctly, the Full Bucket Light should not illuminate.

Hope this helped you and thanks for choosing FixYa.

Light says tank is full, but it is not. i've turned it over but no water runs out. how can i get it started? is there a reset button?


This problem is generally caused by improper installation of the water collection bucket. In not installed properly, the bucket will not make contact with bucket removal safety switch.
When installing the bucket, be sure that you seat it "squarely" from top to bottom into the bucket holder. The bottom of the bucket should not tilt down in any way.

Another cause ( if your unit has one ) is the float valve in the top of the water collection bucket is stuck in the UP position. Which indicates to the units electronics, that the bucket is full.
Remove the bucket and look at the top of it. You may see what appears to be a plastic lever contraption, that is the float valve. If it appears to be in the UP position, jiggle the rod to get it to return to the down position.

I hope this helped you troubleshoot and solve the problem. Thanks for choosing FixYa.

Unit shows full bucket whe bucket is empty and shuts off


I beleive the model you have, has a float valve in the top of the water collection bucket. If it's stuck in the 'UP' position, it would cause the Bucket Full Light to glow. Remove the bucket form it's holder and determine if the bucket does have the float valve. If so, jiggle the float valve arm to get it to return to the Down position.

If the unit doesn't have a float valve, installing the bucket "squarely" into it's holder from top to bottom is very important. If the bucket does not make firm contact with the bucket removal safety switch (A trigger switch), it will cause the unit to think the bucket is full. After reinstalling the bucket, be sure that the bottom of the bucket is not tilted down in any way.

Hope this helped you to troubleshoot and solve the problem.

It goes on and off intermitently. It seems to be the switch where the colector tank slides in


If the water collection bucket is not installed properly, the vibration of the unit during operation, will cause the bucket to lose contact with the safety trigger switch and the unit shuts OFF. Remove the bucket and look up into the cavity to see the switch. This will give you and indication of how the bucket must make contact with the switch. When you reinstall the bucket, be sure that it is squarely in the opening (top to bottom) and the bucket's bottom is not tilted down. However, when this occurs the Bucket Full light usually turns ON. If you're not getting that, it's not a problem with the safety trigger switch.

So, the other thing to check is the water extraction level, you have the unit set on. It may very well be set to high. Lower it to 32 - 25 %. The ON/OF scenario can be caused by an improper humidity extraction level setting.

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

Hi, I have an LG dehumidifier, model number LHD650EBL. I have a hose attached and inserted directly into a drain in my basement, bypassing the water tray. Problem is, my dehumidifier is saying...


Try to see if operating the float lever by hand can make it turn off the 'bucket full' message. Maybe use a rubber band or tape to keep it in the on position vs. the 'bucket full' off position.

Check to see if the bucket has to be inserted for the unit to operate, and if the bucket has a nozzle to hook a hose up to at the bottom. I have a dehumidifier of a different brand that has this feature that works with the bucket in, but with the drain nozzle on the bucket connected to a plastic tube that leads to a drain for continuous operation without having to empty the bucket.

How is your hose attached to the unit if it isn't attached to the bucket?

Good luck on this repair.

Red light comes on for no reason. Danby DDR6588EE dehumidifier


I have a DDR4588EE (same model with 45 pint capacity) and had the exact same problem. It's caused by the float at the top of the bucket being in poor contact with the "full" detector button. When the bucket is not full, the float on the bucket is supposed to press against the button. When the bucket fills, the float is supposed to push up off the button which causes the unit to stop and the red light comes on. The problem is that for some reason, the float isn't pressing hard enough against the button to push it properly in when the bucket isn't full. I fixed it by sticking a few little squares of duct tape (3 or 4 layers) on the float to make it press the button more firmly. Seems to be working fine now. Careful not to put too much tape or it might press too firmly which would result in the float not releasing the button when the bucket is full, and water will spill over.
