Most dehumidifiers have a "Frost Guard" mounted on the condensor coil. If frost accumulates on the condensor coil the frost guard turns the compressor off until the frost melts, then comes back on again. For the dehumidifier to work properly, the surrounding (ambient), temperature must be higher than 65 degress. This temperature allows the moisture in the air to condense on the coils and drip into the reservoir without freezing up on the condensor coil. Also, if the humidity is too low, (below 45%), the same condition will occur. So it will help to keep the parameters in mind when you have this issue.
Thank you for your allowing me to advise you on this issue.

A dehumidifier is just a refrigerating machine with it's shirt hanging out and there is not much in the way of serviceable parts inside.
If the compressor runs - the throbbing sound - and it doesn't collect water then either the intake filter screen is totally clogged with fluff or the compressor has leaked it's gas away, in which case it might run continuously and get hot to no good effect.
If it doesn't run then it may be that the motor capacitor has failed, but that can soon lead to the compressor motor cooking itself; leaving you with an expensive doorstop.
The one thing you might get checked is the "bucket full" switch. There will be a floating part on the bucket which rises up when the bucket fills and eventually makes contact with another part which is connected to a small switch. If that switch has failed you might be lucky and get an inexpensive repair job done.
If these suggestions do help you solve the problem, please give my reply a suitable rating. If they do not, please add a comment with more details so I can try to help you further.

SOURCE: not working
Hate to tell you, but it may be a goner. Many units have a rectangular air filter that may be clogged, but I would still expect to see some moisture removal. Without exact model I'll have to be general,.... remove cover (front or back, depends on model) to see cooling coils. If the compressor is running, these coils should be wet or may have a light frost on them for a time. Not = refrigerant leak. (not economical to repair) If you see one small area of ice,... it's also a goner. If the compressor does not run you could have a bad compressor, a bad defrost control, or a bad control / humidistat. Other than the filter or possibly a fan motor, these unit are rarely economical to repair.

My unit does not collect water any more. It was fine until I lent it to my brother in law and it was returned damaged. Do you know how to fix this

I have a Whirlpool dehumidifier model AD50LJ0: the compressor starts but then appears to trip out. The fan keeps running. It does not condense and water. Can you help?
