When I start the washer, water seems to seep in through the back and not through the sprayers? After the cycle is finished, clothes are still dirty, as if they never washed due to lack of water entering, have a feeling the laudry soap is accumulating somewhere as well as it enters when water is dispensed it is just not entering the tub/washload? Only 3 months old. 

I have a (2009 )WM0642HW.The new ones don't have the Forced Water Recirculation Nozzle that's in the top of the door seal. LG quietly (discontinued) that feature. If you do see a WM0642HW with a spray nozzle in top of the door seal in a showroom somewhere, it was a WM0642HW manufactured ( assembled ) a long time ago.Currently produced WM0642HW will not have the Water Recirculation feature installed. There may still be some older version "new" WM0642HW units out there somewhere? But most of them are display models or unavailable ,and with a shorter motor warranty. 7 years instead of current 10 years on new versions of the WM0642HW.But getting back to your question, the washer fills by water entering the cylinder through the back top left side of drum as it flows from the dispenser compartment via a hose.The opening is right behind the cylinder baffels location. It has no fill nozzle at the front gasket edge like some other brands have. My washer did not clean well at all with full loads. Only after i turned the water level switch under the top lid "clockwise" a half turn ,does it now fill up to the bottom of the door rubber seal.My clothing now tumbles in a pool of water instead of a WICK WATER RUB WASH that it was doing previously. It's a 100 times better with the few gallons of extra water inside, BELIEVE ME. What i say is from experience with this exact model.Turn up the water level so it can tumble in some water. TRUST ME ON THIS ONE! You'll have nothing but grief until you've had enough and have the desire to turn it up alittle.Just have it set to fill to the bottom of the door gasket.Everything will be saturated at the start of the wash and not towards the end of the wash segment.
