I have a cold water flow problem that happened with my old Maytag washer, and still happens with my new Whirlpool washer. The problem is that the cold water flow into the washer slows to a dribble over time. If I switch the hoses, put the hot water on the cold inlet and the cold water on the hot inlet, and then run the washer for a second and then switch the hoses back the right way. the cold water flow is fine, but then slows to a dribble again over time.
