How can I reset my Beko DWD8657 diswasher?

My dishwasher Beko dwd8657 after almost 2 years of normal operation suddenly its LCD got crazy, flashing and starting and stopping cycles all the time. Some times goes completely blank.

Is there any way I could reset the dishwasher from the buttons on the panel? I have tried all possible button push combinations without luck so far, including pressing the start/pause button for 3-7 secs while switching on or not with no difference.

Please let me know.
