The model number that you submitted for the washer appears to be slightly off (EM2688HNMA). I assume that you have a model WM2688HNMA.
You indicated that you pushed the start button and that caused the cycle selector to light up and the display to light for a moment. I think that you must be talking about the power button. If you select a cycle but cannot start it then you could have a problem with the door switch or the console. You could also have the Child Lock enabled. Follow the instructions in your owner's manual to disable the Child Lock if it is activated (press and hold the PREWASH button for 3 deliberate seconds). Here is a link for your owner's manual in case you need it:
If the child lock is not causing your problem then you will likely need to have the washer serviced by a technician. If the washer is less than 2 years old, the electronic control board part may be covered if it is causing your failure (you would need to pay for labor to diagnose the failure and install the new board).
If you need more help, submit more details and verify the model number of your washer.
