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. There's also a chance that the humidity sensor is clogged with fluff, so fooling the system into thinking the room is pretty dry. In that case, the compressor will not run.

A running compressor can usually be detected as a deep throbbing from the machine.
If it is running, but not cooling the pipes, then you may have lost the refrigerant from the system via a leak. If the air coming out of the machine is warm (caused by the compressor running) but there is no water produced this is usually the cause.

If these suggestions do help you solve the problem, please give my reply a rating to help others judge my knowledge / guessing skills.
If they do not, please hold off on the rating and add a comment with more details so I can try to help you further. Cheers, D

Danby 25pt dehumidifier not collecting water, fan is working can hear the compressor kicking in, is almost 5 years old though, is it time for a new one?


Christina, 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%.

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 will help you troubleshoot & solve the problem. Thanks for choosing FixYa.

Everything seems to be working but we are not getting any water in the bucket. The unit is less that 5 years old?? Where should all of the settings be set for??

The Danby Millennium Dehumidifer goes not condense any more. Have unpluged the unit, cleaned all of the filters. Is there a way to reset the unit from the controls?


If you unplugged the heater for 12-15 minutes, after turning OFF the Master On/OFF Switch, the electronics should reset themselves. Also, be sure that you don't have the humidity level set to high. Anything above 60% wont' extract any moisture to speak of. If your unit doesn't have an LED display, set the unit on Minimum.

Hope this helps you. Please let me know. Thanks.

Danby DDR401. Can't get it to remove moisture from the air.


Hi Fred, let me see if I can assist you. 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.

What is the size of the drain connector on a Danby DDR401 not a garden hose connector, that doesn't fit? THX Mike


Strange but true. I had tried to use a steel/brass connector from a garden hose. Although the same size as a normal garden hose connector when used with the nylon threads on the humitifier it simply would not tighten without coming off. I went to my local hardware store and tried plastic/nylon hose adapter to hose connector and it worked like a champ? Although it worked it to if overtightened (and not to much) would also want to fall off? it worked ok and everything is fine.....cheap engineering.
