Whirlpool quiet partner iii will not wash

Hey all. I am new to the forum and am hoping you can help. I have a Whirlpool quiet partner iii model # GU2300XTV80. It will fill with water, and drain, but the water will not spary on the dishes. After it fills, it just sits there qietly until the cycle ends then it drains. What do you think I should do to fix? I have already tried using the reset to no avail. There are no blinking lights. Please help as the wife is VERY unhappy right now. And you know what they say…if she isnt happy, noone is!!!
