Dehumidifier keeps running and no water collects in the bucket

SOURCE: No water collection

compressor may be starved for freon or blockage in freon line...tech must troubleshoot.

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.

Normal 0 When you push the power button, the blower fan comes on. In a few minutes you should hear a second "click"--that is your compressor starting. Do you hear that second click?

unfortunately it sounds as though your refrigerant leaked out. If your compressor is running and no moisture, this is probably the case. What is the temperature of the air coming out?

may have lost ref charge check name plate for type of ref with 12 and 22 cost of gas cost proh. check tubing in rear should be ice cold to gather condensate if not probably lost gas
