Bucket overfills to the point of spillage

The manual claims 'all models have a built in water overflow control' which is supposed to be a red plunger on the top of the bucket that one can turn 'counterclockwise to adjust the maximum water level'. I don't see the red plunger anywhere on the bucket. I do see a float that is supposed to keep the bucket from overfilling but it's not functioning properly. Am I missing a part? Is this oversight from Haier or a misadvertisement?

My maytag M7DH65B2A dehumidifier overflows to the pont of spillage. I removed the resevoir and depressed the switch and the unit continues to run. Does this mean the microswitch is broken? if so, where can I purchase a new micro switch?

Thanks brian

The float is the main feature that keeps it from overflowing. I have no idea why there would even have to be an adjustable component in the circuit. The float is connected to an On-OFF microswitch and may be tested with the unit set to run.
Remove the bucket and manually push upward on the float. If the unit stops running then the bucket may be misalgned,(Make sure float is on the inside of the bucket and not lodged behind the bucket).

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.

The bucket fills up but we have to put a towel down because it leaks all over the floor. What could be wrong ?

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-

It runs but leaks water, water won't stay in bucket

Denise, there are several things that can cause the problem.

1. The water collection bucket is not installed properly. Turn the unit OFF and remove the bucket. While you have it out, look at the top of the bucket, is there a float valve near the top. If so, it may be stuck in the DOWN position, which tells the dehumidifier the bucket is not full yet. Jiggle the arm of the float valve to see if it moves freely. Reinstall the bucket bucket "squarely" from top to bottom into it's holder. The bottom should not tilt down at all, if installed properly.

2. The drain tube to the bucket may be clogged. To solve this problem do the following:

Remove the water collection bucket and look up inside the bucket holder cavity. You will see either a drain hole or small tubing that drains the water into the bucket. Using an appropriately sized, 18" long, plastic Zip Tie, carefully insert the tip of Zip Tie into the hole or tubing. Continue to push it in until you reach a bend in the tubing. You will need to gingerly work the Zip Tie past this bend, until it either bottoms out or you run out of usable Zip Tie. Then slowly pull the Zip Tie back out while rotating (twisting) it. This will breakup any clogs. As you reach the inserted end of the Zip Tie, be prepared, as some water may follow. Reinstall the bucket, plug the unit in and turn the Master ON/OFF Switch to ON. Set the humidity extraction level to 35% or Maximum if you have a manually controlled unit. Allow the unit to run, while you monitor it for any leakage.

NOTE: If you don't have a Zip Tie, you may use something similar ( i.e.a long pipe cleaner), but NO wire coat hangers

3. The water you're seeing may not be from the bucket overflowing or leaking. It's condensation that is has built up on the cooling coils and is dripping down under the unit. If this is the case, it's an indication that the coils are dirty and need to be cleaned. Warm water and dish washing liquid works well to clean the coils. Be sure to rinse them with a damp rag, dry thoroughly and spray a light coating of WD40 on them.

I hope that all the information I have provided will help you troubleshoot and solve the problem. Thanks for choosing FixYa.

Does not shut off when bucket full and overflows.

From what you have described, the float valve is the top left rear of the bucket may be stuck in the down position and is not rising when the water level rises to the shut off point. Jiggle the float valve handle to free it up. In addition, the bucket may not be installed properly and is allowing water to leak onto the floor. Be sure that bucket is installed "squarely:" into it's holder from top to bottom. When installed properly, there should be no downward tilt at the bottom of the bucket.

To further assist you, I have included a link to your Owners Manual in case you have misplaced yours. You may download and print this manual for future reference.

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

its the bucket switch on the unit thats bad,it controls the water level overflow so unit shuts off when bucket is full,its at the top rigt side of the bucket mounted to the float in the bucket and there is a replacement available part # AP3136674,on some units depending on the mounting hole size,you may need to use some old switch mounting parts on the new switch so it fits

When the bucket is full it is not turning off and overflows.

What you should do is remove the bucket and look for a pressure switch which is most of the time under the bucket and test it by pushing down on it's plunger, if the unit turns off either the switch needs adjusting or is there is a plate above it needs the be bent .

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

Are you supposed to put water in the bucket of the dehumidifier or is the water that is in the bucket now from using the dehumidifier? Dumb question I am sure. But I am renting and have never used one...

The dehumidifier condenses the water on its coils and then it drips into the bucket. Dump out all of the water when the bucket is full. This model has a light that tells you when it is full. If the dehumidifier gets ice on the coils, it needs repair (low refrigerant).

I hope this helps.

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.
