Whirlpool fills up between loads

I don't know whoi suggested a $10 part to you, but Sounds like you need a new water valve (some debris inside the valve causing it to not fully close). These are availible from your local appliance parts store or on line from the manufacture. Once you have your replacement, just take the 3 #20 torx screws out of the rear of the top panel slide the whole panel slightly towards the rear and lift it off. On the outside of the washer on the back panel, You should a light blue plastic thing that the 2 matching hoses from your house connect to. Turn your water off and remove these hoses. Just beside them you will find another #20 torx bit screw (some models use a #10 or #15). Remove this screw as well and slide the valve slightly to the side. It will come loose. Now from the inside of the machine, you will see 4 blue wires going into 2 connectors on the valve. Remove these
connectors only by pulling on the connectors, not the wires. Lastly you will see a small black hose with a green or silver clamp on it. Squeeze the clamp with a pair of pliers and then slide it down the hose. The hose should now pull free of your old valve. Re-assemble in reverse.
