My Kenmore washer leaks water while it is spinning/pumping water out. The water shows up at the front right corner of the machine leaking out from underneath. When I turn it over though there is no obvious wetness on any of the hoses or on the pump. Nor is the metal gear box in the center rusty. So I am concluding that it is leaking from the plastic surrounding that goes around the metal tube. Or perhaps at the top of this. Is this common? How can I access these parts to see if there is a leak? Or how to find a leak in general?
