I have a Kenmore dishwasher MD# 587-1656581. It is getting water to the inside of dishwasher but the arms won't spin. If I poor a gal. of water inside the dishwasher the arms will spin for one cycle. How can I fix this problem?

You must have a water solenoid problem or a safety bad or tripped. Here are some manuals: https://dl.dropboxusercontent.com/u/8010163/Whirlpool_Kenmore%20Dishwashers.zip
