Hi,
There are many reasons for a dehumidifier to not work or collect water.
Here is a tip that I wrote to help people to figure out what is going wrong with their dehumidifier.

Hi,

First, make sure the humidistat isn't set too high by adjusting it to the lowest humidity setting and running it again. Next, test the dehumidifier by placing it in a closed bathroom with a hot shower running. If you don't see water collecting in the unit after several minutes, turn the unit off and clean all dehumidifier filters and coils. If, after adjusting the settings and cleaning the unit, you still don't see water collecting, you may have a refrigeration issue. This situation will have to be addressed by a qualified technician.

Take care.

If the humidity in the air is low, then it will shut off. When you reset the unit it will run until it senses that the humility is at an acceptable lever based on the settings. It is also possible that there is a malfunction. If it is humid in the room, and it will not run then it could be the humidity sensor, or control unit.

If the unit is malfunctioning, and it is no longer under warranty, then it is not worth it to fix it. If it is under warranty then the manufacturer will repair it.

Hi bash123er,

If you're facing these problem that your dehumidifier is not producing water and compressor is shutting off then there are few things that needed to be checked on:

1. The very common problem with most dehumidifiers is the circuit board relay. If this has gone bad then it will require replacement.

2. The compressor has already gone bad. This is the problem if you notice a buzzing sound every now and then from the system.

3. You may also have a refrigerant leak. This happens when the compressor is running but coils are not getting cold at all.

4. There will be cause of low water production if the fan is not running and the compressor does. If fan is not running then you have to replace it. This also will result frozen coil.

5. Check to see also if your coil is blocked. This will also result into no water production.Air needs to be continually moved over the cold coil to get the water out of the air.

If you're not comfortable doing the checking and repair yourself then I would recommend that you contact a repairman.

Hope this helps.

Thank you for using FixYa.

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

1. The humidity extraction level is set to HIGH. Lower it to 32-35%. If you have a mechanical 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 - 65 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 to trouble shoot and solve the problem. Thanks for choosing FixYa.
