Sooo with my model just for anyone looking this up. My son loves pushing buttons and one of his favorite is the “delayed start” button. After researching, cleaning out the filter, unplugging the dishwasher and most everything short of pulling my hair out, I found out that the little nugget had pressed the delayed wash button. Which, you would think would reset when you reset the machine but evidently not. Pushed the delayed start button and cycled through 12 hrs and bingo, it ran....

E4 means dishwasher sensor is detecting the dishwasher is over filling. First thing I would check is the float. You will want to make sure it travels up and down freely. Open your dishwasher door all the way. Look on the right hand side (could be in a different location on your model) you will see a round thing. Kind of looks like a air hockey pusher. Try moving it slowly up and down making sure it’s not stuck open.
If this didn’t work then I would lean towards a faulty sensor.
It’s possible you could have a faulty board as well.
It is my opinion unplugging it will have no effect on this particular issue.
I hope this information has helped. God bless and have a great day.

I DON'T KNOW. INSPECT CHECK FUSES OR CIRCUIT BREAKERS. BE CAREFUL AND MEASURE FOR ELECTRICITY AT WALL RECEPTACLE.
