This can happen if the air is very dry and no water can condensate from the air. Check the coils to see if they are cold to the touch, actually they should be very cold, like almost freezing. If not then the refrigeration system of the dehumidifier has gone bad. To repair that you will need a person certified to work on refrigerant systems with specialized equipment. In many cases the costs to repair the refrigeration systems will more than the cost to replace the whole unit.
This should give you a brief overview of the problems that you can have with a dehumidifier and some of the things that you can do to help get things working.

Try setting you temperature or fan speed lower this may help.
In order for the unit to remove moisture the coil has to be below the dewpoint.

Hi,
There
are many reasons why a dehumidifier will not work or collect water.

There are 5 basic, but solvable reason for what you described. Please pay particular attention to numbers 1 & 2. However, running to dehumidifiers in the same proximity may be the problem. ON is doing the lion's share of humidity extraction, leaving little or nothing for the other to extract.
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.
