Is the dishwasher in Standby or Sleep Mode?
Be sure you have disabled Sleep Mode by pressing either START/RESUME or CANCEL, or opening and closing the door before selecting your cycle/option.
Has a delay wash option been selected?
A delay wash option runs the dishwasher at a later time or during off-peak electrical hours. If the delay wash has been selected, the dishwasher will not run until the delay time is reached.
To Turn Off the Delay Wash Feature:
Press CANCEL/DRAIN to cancel the delay. Press START/RESUME to start the cycle.
Is the door completely closed and latched?
Make sure that the door is completely closed and latched. A lower dish rack that is installed backward can also cause the door to not latch properly.
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.
