Hello Susan, can I have the complete model number please? Where does the pool of water exactly located? Can you described it further please? Usually, if there is a plug, you would not miss it at the bottom of this place. How ever, if there is no plug, then I would suggest that you can just use dry rugs or paper towels and absorb the water on where it is. Just unplug the unit first because it could be near a rotating fan blade or a very hot discharge pipe which can hurt you.
