Maytag M7DH65B2A Dehumidifier - Answered Questions & Fixed issues

This problem is usually caused by an improperly installed water collection bucket or the float valve inside the top of the bucket is broken or stuck in the DOWN position.

To troubleshoot this, turn the unit OFF & unplug it. Remove he bucket, check the float valve's position. If it stuck in the UP position, jiggle the handle to make it return to the DOWN position. This will also allow you to determine if the float is broken. If all this checks out, reinstall the bucket "squarely" from top to bottom into the bucket holder. It must make contact with the bucket safety removal switch on the back wall of the holder. When installed properly, the bottom of the bucket will not tilt down at all. Plug the unit in and turn it ON. If everything was done correctly, the unit should start within a few seconds.

Hope this helps you to troubleshoot and solve the problem. Thnanks for choosing FixYa.

If it is not running because it thinks the bucket is full even when it isn't, the problem is that the float is broken or jammed. A replacement is no longer available, but you can find the small switch and tape it so it always stays on. It won't shut off when the bucket is full, but it will run. This assumes all the other panel lights come on properly - you didn't provide much detail about what works and what doesn't work.

Sounds like your relay switch isn't connecting....

If it is like mine, the plastic part attached to the float in the collection bucket is broken and no longer actuates the switch that indicates the collection bucket (holding tank) is full. When I checked several years ago, the replacement part was no longer available. I used tape to keep the switch in the position that allowed the dehumidifier to operate and attached the hose connector to allow the condensate to drain. The collection bucket isn't needed anymore with this arrangement.

THIS IS NOT A GOOD THING TO DO

you take out the filter screen and vacumn it or run it under warm water. As far as the full light is concerned it probably means the last time you emptied it you didn't seat it back into the unit properly. If you take the tank out and reinstall it the light will probably go off. Sometimes I have to do it a couple of times before it seats properly.

I believe you have to put a plug to drain that drains into the tank ,then it can only drain out the hose.

If the room tempature is close to 60, the coils may be frozen (completely encased in ice). If this is the case, move it where the water can drain off - about 1 gallon which may NOT run into the drain bucket.
I out mine over the floor drain.
Turn off and it will defost over night.
Only specially made dehumidifers work below a room temo of 60 degrees (the temp of a basement in winter).
Does it need to be running? A digital humidity sensot from Radio Shack is cheap and may tell you the humidity is OK - only 50% or less.

I've replaced mine twice.  water pools under the board and shorts it out.  I raised the mounting points this time around.  I found the board at Appliance Parts 866-312-3498

I would think the level sensor is dirty or defective.

I have the same unit and found that a sensor that attaches to the evaporator and the attachment holding it to the coil rusted away. Made a new clip from copper tubing and now it works again.

Hi,That is not that hard to fix and you can easily buy the parts yourselfonline...Here is a tip that will help you with the online buying...How to Buy Appliance Parts OnlineHere is one site that I recommendhttp://ping.fm/zJDAMheatman101

Hi,If you are blowing fuses and GFCI's your compressor is either not starting at all, is starting hard, or is at least grounding out momentarily...at any rate the compressor is failing, and that is not economically replaceable..heatman101

The problem you're experiencing can be caused by several things:

1. The humidity extraction level is set to HIGH. Lower it to 35%

2. The air intake filter is dirty or clogged. Remove and clean the filter, as necessary.

3. The float valve in the top of the water collection bucket is broken or stuck in the UP position.
Remove the bucket and inspect the float valve for damage and freedom of movement.

4. The water collection bucket is not installed properly. While the bucket is out for checking the
above,be sure to reinstall it "squarely" from top to bottom into the bucket holder. It needs to
make firm contact with the bucket safety removal switch on the rear wall of the bucket holder.

Here is a short list of some replaceable parts for this unit. Which fan are you speaking of here?

Michael, the problem you're experiencing is caused by one of two things. Solving either requires turning the unit OFF , unplugging it and removal of the water collection bucket.

1. The float valve in the top of the bucket is either broken or stuck in the ON position. Check the arm of the float valve to see if it moves freely and is not broken.

2. The bucket was not reinstalled properly. Install the bucket so that it fits "squarely' from top to bottom into the bucket holder and that is it makes good contact with the bucket safety removal switch on the rear wall of the bucket holder.

Skooter, the problem you're having is a result of either the drain hose being clogged or the inner tubing of the hose connection is clogged. When this happens the water is diverted into the bucket. To solve the problem do the following:

Turn the unit OFF & unplug it. Using an appropriately sized, 18" long, plastic Zip Tie, carefully insert the tip of Zip Tie into the hose connection and 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. Reconnect the hose, 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 the hose end for water flow. . Be patient, as it may take up to 10 minutes or water for water to appear.

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

Does bucket overflow into drainpan

Hi,There are many reasons why a dehumidifier willnot work or collect water.Here is a tip that I wrote to help people to figure out what is going wrongwith their dehumidifierDehumidifier is running but no water is in bucketheatman101

Patti, the problem is not the drain hose (unless it's clogged or exceeds 48" in length). The internal drain tubing to the hose connection is clogged. When this happens, water is diverted to the water collection bucket. To unclog the tubing do the following:

Using an appropriately sized, 18" long, plastic Zip Tie, carefully insert the tip of Zip Tie into the hose connection hole and 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. Reconnect the hose, 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 water flow. It may take 10 to 15 minutes for the water to start flowing, so be patient.

I hop the helps you, Patti and thanks for choosing FixYa.
