Check the power cord for rips of loosness where it enters the unit. if the power cored is fine, this will usually be the result of a power supply board failure. you should replace the power board in this case. the original board is unable to process the AC current at this time.

Pull out the water collection tray. You will see a small pipe (about 1/2" diameter) in the top of the area where the tray came from. This is the "drain" that fills the tray. Connect a hose to this pipe and run the hose to a floor drain if you have one. I used a section from an old garden hose for my unit. There also may be a small opening in the back wall of the dehumidifier to route the hose more aesthetically.

Make sure your coils are clean and free of restrictions and that the fan is running. If this is ok, then it is probably a leak in the system resulting in low charge. Cost of new dehumidifier will be cheaper than having it repaired.

> fuse embedded in the outlet (?)
Not a common arrangement so I believe you have it plugged into a 'Ground Fault Interrupter' (GFI) that is a protective device to prevent us from being shocked or killed by lethal currents in case of an electrical path that shouldn't be there.
These function by comparing the current flow in the hot and neutral lines. If there is a slight difference between the two currents, it will interrupt the AC line and will have to be reset (no fuse, just a button) to restore power to the outlet.
Dehumidifiers are an excellent place for current paths that can create this imbalance; moisture and a path to ground which is the third pin on the AC plug. That ground is attached to any metallic parts inside the unit and you likely have some current flowing from the hot side of the line to some exposed, grounded metal that is creating the imbalance.
To verify this, you will need a plug adapter for adapting the three contact plug to a two contact plug. Any hardware store has these. Disconnect the unit's AC plug, plug it into the adapter and then plug that into the AC outlet you are using.
NOTE: If there is electrical leakage inside your dehumidifier, this will constitute a shock hazard! Do not touch anything metallic on the outside of the unit! Once you have seen the unit run without turning off for a day or two, pull the AC plug from the wall, do not touch the unit to turn it on or off. It probably isn't deadly but don't take any chances.
If running it this way works, I wouldn't trust the unit around a small child or anyone with a heart condition and to me, it means the product is defective and should be junked.
