Dehumidifier runs but does not extract water

Runs constantly but no water entering catch tray. What can I do? Is this worth repairing? Unit is over a year old.

    Setting is below ambient humidity level (so runs constantly).

  • Anonymous Nov 06, 2007

    The compressor is overheating and there is no water filling the bucket. It was so hot that I could smell the plastic overheating ...

    It's just over a year old. Why cant they make these better products so I dont have to buy a new one every 2 years... of course "Made In China"

    Same problem with a 2-yr old. unit.. runs but does not extract water but humidity level shows 75% so bought a new LG one which shows same humidity level and works fine (extracts a lot of water)..So is the maytag worth repairing? If so, where?

    Unit Running now for 3 days, Not a drop of water in catch container. We have had unit for about 4 years and never had any problems before.

    Dehumidifier runs cotinuosly. Collects very little water. Digital settings don not work.

  • catstwo Jul 03, 2008

    Same problem. Runs constantly but does not extract water. Did remove and clean the filter.

    It's running, but it doesn't collect water

    Same problem, only 1 year. Still under Warrenty (5 years). Neither Sears nor Fedders can honor the warranty. A post on the Internet shows Maytag (maybe only for Dehumidifiew, who know how they play this game?) files for chapter 6 bankruptcy protection. I guess I'll have to get a new one. Anyway, I think the unit has lost it's freon.

Dehumidifier runs well, however will not drain any water

Found out about the filter on the left side of the unit. Mine was caked with dirt and would not allow air to pass. Cleaned with nozzle from vacuum and it works great now.

Either the compressor has suffered an electrical failure, or the unit has lost it's freon charge. These are generally not worth repairing. Recommend a new unit.

Unit runs but does not extract water from air - no water in unit nor drain hose

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 dehumidifier

Dehumidifier is running but no water is in bucket

Machine runs, but no water is coming out into the bucket

There are several reasons this may be happening. The 2 primary reasons are the humidity extraction level is set to high. Lower it to 35% . The lower the setting, the more moisture/humidity is extracted from the air. The higher the setting, the less if any moisture/humidity will be extracted from the air.
On most humidifiers the fan runs almost constantly while in operation. The idea is to continually move the air around and when the unit senses a rise in humidity, above what you have it set on, the compressor will turn ON to extract that humidity.

The 2nd thing that causes the problem is a dirty of clogged intake air filter. Which is easily solved by removing and cleaning the filter. Which should be done at least every 2 weeks, while the dehumidifier is in operation.

I said there were 2 reasons. Actually, there is a 3rd. Not enough clear air space all around the dehumidifier. A minimum of 12" should be maintained during operation.

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

Runs - but no water in bucket

Hello. If your dehumidifier doesn't seem to run often but the humidity in the room is high, try adjusting the humidistat control on the dehumidifier to a dryer setting. If the dehumidifier seems to run constantly, but there's little or no water in the container, there may be a problem in the refrigeration system. Try cleaning the unit. If that doesn't work, you can't repair the refrigeration system yourself, you need a qualified appliance repair technician to do that.

Unit runs but doesn't pull humidity out of room, filter clean

Possibly lost refrigerant from system- check warm air is coming out of machine. Otherwise it could be dirty filters, and not getting enough air over evaporating coil. Other than this, replacing parts is usually more expensive than buying a new dehumidifier :(

Dehumidifier m7dh65b2a

Mine leaks. Had leaked at other times but i took the vacuum cleaner to the front drain spout, that leaks into the removable basin. That worked in the past, but i't's not working now . The water is overflowing at the back of the catch tray and leaking out through the bottom underneath. The holes are clear, so it shouldn't be doing this. I am stumped.

The dehumidifier runs a long time & does not remove much water.

Hi,
If you haven't done so already, try removing and cleaning the inlet filter screen which is almost certainly just behing the inlet grille. If this is blocked with fluff then no moist air will get to the cold pipes, so little or no water will be extracted.

Hope this helps. If this "fixes ya", I'd appreciate a rating for my reply, If not, please delay the rating and add a comment with any extra info you have and I will try to think of something else.
