we have a m/c that when you shut the door to start the cycle it will count down and then will show “door” after a short while but the cycle hasnt started
If the door actually locks, but the machine still does not start, you are almost certainly looking at some sort of computer problem. This can be extremely difficult to giagnose acturately, so probably engineer time.
