My portable frigidaire air conditioner bucket light on

The actual bucket is located inside the machine at the bottom.  To access it, you must unscrew all of the screws and take the front panel off.  You cannot empty it from this side so it is not worth taking the machine apart.  
However, in order to empty the bucket, there is a small black plug at the bottom left hand side at the rear of the machine.  Be careful when pulling out the plug because the water will immediately drain.  
Good luck.
