Question about Maytag M3DH30B2A Dehumidifier

1 Answer

Unit overflows the condensate container with water.

The unit is 4-1/2 years old and still works fine, however, the water generated seems to fill the entire container. The shut off is not working. I can toggle the styrofoam float back and forth so that is working it seems like. So, I don't know if there is a switch that is shot or what the problem could be.
Any help would be appreciated.

Thanks.

    Thanks for the feedback. Can you tell me what part of the outside shell of the unit I would need to remove in order to see the switch to disconnect it?

    Thanks.

To find out if it is the switch, unplug the unit and disconnect one or both of the wire to the switch.Plug back in and see if it quits filling.
If so it is most likely the switch is bad.

The motor is still running fine, but the dehumidifier is no longer extracting water from the air and the water container is not filling.


John, there are 5 basic, yet solvable reason 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%.

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.

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

There are 5 basic, but solvable reason 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 a manual unit with
no led screen, set the manual control to 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. The filter should be cleaned once every two weeks.

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.

Water condenses on top of dehumidifier


Your unit has a sealed system leak. The sealed system is warrantied for five years. Check your owners manual for this info. You will need your receipt and to call an authorized LG warranty dealer to exchange it.

Dehumidifier leaking onto floor.


You should clean off the condensor coils with a vaccum and soft brush. Also, check up inside the area where the condensate drips into the collection reservoir (or goes directly into a hose attachment discharge) to see if something is partially obstructing the water flow and is dripping onto the floor, etc.

You might find that you've got some buildup of dust, dirt, and some other gunk that is mis-directing the water (condesate) that the dehumidifier is drawing out of the air.

Lastly, check the unit to see if it's level, but frankly, I highly doubt that's the issue, based on the 5+ years of good working service for you.

So long as the unit is still running and keeping the humidity in check, (if the above steps don't resolve the issue), I'd continue using it until it finally quits running, but I'd put a plastic boot/shoe mat under it to catch the small puddles of water.

The dehumidifier should draw the small puddles, so it'd be less expensive to get a $4 boot mat than dropping another $240+ for a new unit, as your's seems to be working fine, aside from the occaissional puddle issue.

Hope you find this Very Helpful and best regards!

FULL LIGHT FLASHES


An automatic overflow switch and Container “Full” indicator light are provided to turn the
dehumidifier off before the container overflows. When the indicator light on the control panel
glows, the water container must be emptied. If the light remains on and the dehumidifier does
not begin to operate make sure the float is attached to the water container.


When the condensate water container is full, the indicator lights up.
1. Turn the power off before removing container. Wait 3 minutes for
any remaining water to drain into the condensate container.
2. Tilt the container forward then lift carefully by the handle.
3. Empty and gently re-insert the container.
Important:This water is not suitable for drinking.

Please rate and god bless:)
