Hi there. I've had this dishwasher for less than 2 years and last night is just stopped working. I tried turning the breaker switches off and on, the child lock is not engaged and nothing worked. It will beep when I shut the door and there are lights on the buttons, but that's it. So this morning I tried to disconnect the control panel and was able to disconnect all plugs except the one connected to the buttons. Is there some special trick? Yes, I am pressing the little "lock" on the side and pulling as hard as I can without damaging it but it refuses to budge.
