Question

Have a whirlpool gold dishwasher.The problem is that the clean lite on the control panel flashes not allowing the unit to work.I installed a new disposal and forgot to remove the plug for the dishwasher drain hose.When the flood happened I opened the door in order to stop the dishwasher.Now the unit will not work.The lite flashes 7 time ,then it pauses and flashes 7 times etc.Is there a reset procedure to run in order to get the unit to work or do I need to buy a new control panel?
