Overflow the water fills up to the top of the bucket so when i remove the bucket to empty is spills all over the place

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.

Where are you running the hose to drain it? If the end of the hose is higher than the top of the bucket, then the bucket will fill and overflow. The drain hose must drain out into some place that is at least lower than the top of the bucket. That way the bucket won't overflow. Basic physics.

Good Afternoon Friend,

I understand that the bucket fills with water and overflows on your Frigidaire dehumidifier, model# FAD704DUD. Please make sure your dehumidifier is installed on a level that will support it with a full bucket of water. If the dehumidifier is moving when it fills with water then this could possibly be the cause of the bucket overflowing. I ask that you please follow up with a comment on the post, at your convenience, to advise if further troubleshooting is needed or if your appliances status has changed successfully. Hope this is helpful.

-Best Regards-

More than likely, the float valve in the water collection bucket is stuck in the DOWN position. There for the automatic shut off does recognize that the bucket is full. Remove the bucket and check the float valve in the top of the bucket. If it's stuck in the down position, jiggle the arm to get to return to the UP position. Be sure to turn the unit OFF & unplug it before doing the above.

Hope this helped you to solve the problem and thanks for choosing FixYa.

The leaking problem usually happens for 2 reasons,

1. If your unit is equipped with a float valve inside the top of the water collection bucket, it's stuck in
the UP position. Turn the unit OFF and unplug for the wall outlet. Remove and empty the bucket
if necessary. Look at the foam ball on the end of the float valve arm. If it's in the UP position
jiggle it, so that it returns to the DOWN Position. That should stop the wter from overflowing the
tank.

2. If the bucket is not installed properly into the bucket holder. Remove the bucket, empty the
bucket, if necessary and reinstall it. Be sure that the bucket fits "squarely" into the bucket
holder from top to bottom and that it does not tilt downward at the bottom.

It's also a good idea to check the pump switch for continual draining, to make sure it hasn't been accidentally turned ON.

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

This is usually caused by the water collection bucket not being squarely in the bucket holder from top to bottom. If you haven't already, remove the bucket, empty any water that's in it and reinstall it. Make sure that once it's in place, the bottom of the bucket is not tilting down at all.

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

In most cases this problem is caused by the water collection bucket not being installed properly. It may not have been pushed in far enough to allow the full switch to activate when needed. Be sure that each time you remove the bucket to empty it and then reinstall it, that the lift handle of the bucket is all the way in down position and that the bucket is fitting squarely into the holder from top to bottom.

Note: Your specific model has been discontinued by LG. However, some parts are still available if needed.

If you run your dehumidifier constantly and don't want to make a repair to it. You may want to consider using a drain hose, rather than the water collection bucket. This would require a floor drain close to the unit, though.

Hope this helped you to troubleshoot and solve the problem.

I have the same problem. Some kind of clog near the sensor I'd imagine. Where is the sensor for that?

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.

Check the float first - be sure the styrofoam on the bottom is still intact.  Be sure that you can move it up and down freely (and easily) with the bucket out of the machine.  If that is not bound up, and the foam is in place, next check the switch in the dehumidifier itself.  It's directly behind where the float goes - the way to test it is to turn the dehumidifier on and push the metal tab in with your finger.  The machine should cut out immediately - if it does not - the microswitch needs to be replaced.  (they're very cheap, and simple to replace)
