Cycle power to the control to reset the dishwasher:
Much like a computer, resetting the dishwasher control can sometimes solve the issues you are experiencing. To reset the dishwasher control panel, it needs to be disconnected from the power source for one minute. If your dishwasher is plugged into an outlet, simply unplug the unit for one minute and then plug the unit back in. If the dishwasher is hard wired to the power supply, turn the breaker off at the home electrical panel that powers the dishwasher for one minute and then turn the breaker back on.
