Had a similar problem and it was the bellows from the main tub to the pump and front clean out drain.. If the crack is small and the load does not make the drum vbrate the leak is minor or non existant.. If the load is large and the drum wobbles a lot the leak will be present..PArt is inexpensive but its loads of fun to replace. ( I didnt bother disasembling the top and front panels I accesed it through the back)
Ohh by the way , you guys have a great site here..
