Water could be from the frost in the unit, it has overflowed the drain cup.
Also the compressor line running in the drain cup helps with evaporation of the water so if the compressor is not cooling this line never gets warm.

Double check that the compressor is running, it should be warm and you should be able to feel it vibrating.
If yes
Check to be sure that the evaporator fan is running.
Remove the cover so you can see the evaporator coils.
If there is no frost on the coils your sealed system is toast.
If there is just frost in one area (usually where the freon enters the coils) or it is blotchy then you are likely low on freon.
Of coarse the above is also dependent on how long it has been since a defrost cycle.

Either of the above is an expensive repair and it is probably better to put those dollars toward a new unit.
