We have an Electrolux dishwasher model EWDW6505GVO. A few weeks ago, the door edge display (which also contains all the touch controls) went dead, apart from an occasional beep when passing a finger over it. This was a week before the warranty ran out. Great timing! We called the service department and they diagnosed it needed a new control board, over the phone. It was ordered and delivered to our house, and the repair man came and installed it. Great.
Today, with the warranty now out of date, it did exactly the same thing. I am very suspicious that it is the control/display board again (I fix electronics for a living), so wondered if any one has experience of a common fault in this dishwasher.
