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.
Dehumidifier is running but no water is in bucket

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.

If the machine's compressor runs when you switch it on, then turn the machine on maximum and let it run for an hour or so. Then check the coils in the back with your hand. If they are not getting cold at all, then there is a significant problem with the refrigeration process in the unit. It may have developed a leak and allowed your refrigerant gas to escape, or there may be another internal problem with the compressor. Either way you would need to have it serviced by a fridge technician, or more likely just replaced with a whole new unit since both options can potentially cost about the same.
If the unit runs normally and the coils are getting cold, then make sure they are not totally icing up which will impede the unit's performance. If your dehumidifier is freezing up then that probably means the unit itself is actually working well and you probably just have the unit turned up too high for the conditions.
Try turning down the setting on the unit so that it cycles on and off every few hours and does not run continuously.
Also try using some warm soapy water to clean off any dust or oily residue from the cooling coils in the rear of the unit. Remember to also clean the air intake filter while you are at it.
The ambient temperature in the room may also be a bit too low, so you can try adding some heat to the room if necessary. A dehumidifier will not work properly if the ambient air temperature is too low. Basically, the warmer and more humid the room is, the better they work. Since warm air rises, you can even try lifting the unit higher up off the cold floor onto a bench or table where the air is warmer.
Sometimes the drain tube leading to the bucket is clogged. You can often clean this out by inserting the pointy end of a long heavy duty plastic zip tie and jiggling it around a bit. Do not insert anything metal or sharp into the tube or you may damage it.
