Leak appeared after final spin cycle. Peering underneath machine water was dripping from bottom of drain pump. Ordered a new one from AppliancePartsPros to replace it. Repair was actually much easier after removing the back panel sheet metal cover to expose the pump. When replacing the pump I discovered that the drain hose had a small crack propagating from its molded notch(typical stress area in molded parts). Reinstalling the drain hose, I moved its clamp up above the crack and leaking has stopped. I did order the drain hose, but will wait until a later date to replace it.
