Bosch as you know is a German machine, Beriet in German means 'ready'. It seems your machine has reverted to German language setting. I havent come across this before but it is possible it has been accidently been switched into diagnostic mode.Bearing in mind it is saying 'ready' doesnt sound like a fault warning. The above may be some help but dont know how to reset it off hand . Cheers
