Excessive, intemperate, superfluous.

Does "surfeit" have an adjectival counterpart?
After every load there is always some water left in the bottom of the drain basket/filter.  It's not up into the dishwasher itself, but when I reach into the filter to clean it, there's always water in it.  I have a GE QuietPower 3.

Is this expected?  If not, what can I do about it?
