Water fills for initial cycle then stops

[SIZE=3]My Whirlpool washer fills with water for the initial rinse cycle, but will not fill for the 2nd cycle. When I stop the machine and let it drain, it will no longer fill for even the 1st cycle. If I wait for about 30 minutes and start again, it will work once more for the initial rinse cycle, but still not the rest. I have tired to set the washer with the factory default code and settings, but it has not help yet. I also took everything that I know apart to look for clogs, breaks, etc., but nothing unusual (there was some grim in the area where the shredder is, but nothing major). The machine seams to operate normally, except for the water fill issue….[/SIZE]
