Hello Pat,
Take off the cold water hose from the back of the machine and you should see a small plastic filter in the washing machine part, pull it out and discard it, if that does not work then chances are you have low water pressure, MAKE SURE YOU TURN THE WATER OFF TO THE MACHINE BEFOR YOU UNDO THE HOSE ! you will get some water coming out of the hose when you take it off so put a bowl on the floor.
