Does anyone know it there is a reset button on the pump. We shut it down to drain and clean it and it won't restart

Do you have a door safety switch?
Verify power to the pump, panel may not be putting out.
All Valves open(Flow)?

Check your safeties and switches with a meter to know which one is open. If you read voltage across a switch it's open when you have voltage to ground. See: https://dl.dropbox.com/u/8010163/Whirlpool%204322537A%20How%20to%20use%20Test%20Equ ipment%20Service%20Manual.pdf
