Only thing to do is open it up and have a look see if there’s anything obvious gone wrong.
A favourite is that the base will fill with water due to overfilling, bang, dead. And, if that’s the case, my best advice is to buy a decent one and not to waste time on this.
i belive thats a beko dishwasher full size i could be wrong tho
if dead could be many things ,
check where the main cable go to in side the machine
unplug machine don,t work live
my guess would be either some kind of interfance filter/suppressor or faulty module, but as kwatt say could be cause by leak that blown the board or faulty componet
yes that is a beko made dishwasher, have done a few mains switches on these also if the top corner screws in the facia which hold wooden door on are too tight then the mains switch will stick so check that first
