20 Most Recent Maytag M7DH65B2A Dehumidifier - Page 2 Questions & Answers

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.

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

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.

There are 5 basic, but solvable reasons for what you described. Please pay particular attention to numbers 1 & 2.

1. The humidity extraction level is set to HIGH. Lower it to 32-35%. If you have an analog unit
set the humidity extraction knob on Maximum.

2. Air intake filter is dirty or clogged. Turn unit OFF, & Unplug the
Unit, before removing to inspect & clean it, if necessary. If washed,
allow filter to completely dry before reinstalling. DO NOT operate
the unit without the filter.

3. Obstructed air flow. Maintain a minimum of 12 to 18" of clear air
space around the entire unit.

4. Cooling coils are dirty and need to be cleaned. Use warm water & dish washing liquid to
clean the coils. Rinse and wipe dry. Apply a light coating of WD40 to the coils.

5. Ambient air temperature at floor level is between 40 - 60 degrees.
dehumidifiers do not work well between those temperatures
(Unless, you have a Low Temp Unit). This applies mainly to
where the air temperature at floor level is colder than at shoulder level
in basement applications. Raising the unit up off the floor,
onto a sturdy table, counter top, etc, that can handle the weight
of the unit, plus a full tank of water, will usually resolve this
problem.

If none of the above solves the problem, it may be a case of the compressor needs to be recharged with refrigerant gas or that the humidity condenser sensor has failed. These things usually occur in units that are 5 years old or older. It's rare in a unit younger than that. But, it can happen.

I hope this helps you ro troubleshoot & solve the problem. Thanks fr choosing FixYa.
