This afternoon I went to the boat and noticed that there was a little bit of water in the dry goods compartment in the galley.  This is not the first time it has happened but earlier I attributed having left the valve for the fridge pump out open which resulted in a couple of gallons of water in the fridge and somehow water running under the sink.   The valve has been closed since them with no water anywhere

Today I went in and noticed that there was about a 1/2 cup of water in the dry goods compartment again. Has anyone else had this happen and have any suggestions as to the source?  It appears to be a self-contained tub except for where it joins with the countertop.
