Dishwasher displayed a code and would no start or run. Samsung recommended a local service Dept. That company was impossible to connect with to set an appointment. Once appointment was made tech didn’t show due to personal car trouble. Mew appointment was six days out. That was a Sat. Appt was scheduled for 10am. Tech showed at 530 pm. He did not have all the parts. Tech came out six days later different tech. Said different part was needed. Tech scheduled for four days later. Day of appointment message left on phone part was not available for me to call for new appointment. Tried to call numerous times no answer.
