I check your codes information in your very helpful webpage, and after reviewing the comments of several smart users of your service, I realize that it was the heating sensor problem. I followed the instructions and the very down to business diagrams (thank you for that too) showed me that the sensor was not difficult to replace.
For all the "I can fix it" like me. I would like to advise them to make sure the electric breaker is OFF and the dishwasher is DRAIN because water and electricity do not mix as you know.
and enjoy the satisfaction of solving a problem and saving some money in the process.
thank you for reading
sincerely: Israel.
