UNPLUG MACHINE, remove outer decor door,(if fully integrated should be 2 long screws one in each top corner and 2 long screws half way down each side of door then lift door off bottom brackets). Then remove OUTER steel door, then remove top plastic panel, as well as screws around panel it has one each side in the stainless steel, then you will see the door lock, replace it and the wires on the micro exactly as they are.Cheers
