that error has happened to me when I turned the tm on and had the speed button already turned higher than 0. Normally it then went away. Yesterday my dough setting wouldn't work - made no sound nor anything so I unplugged the TM for 10 minutes and it reset itself. i have had many electronic problems with my bimby and it came back from maintenance 3 weeks ago, I hope that yesterday was a "one off" and not the start of the problems....All the best and welcomeBarbara
