I have a series 100 HE with similar problem. (1) Fills with water normally (sensing light on) (2) Upon completion of fill lid lock light comes on and lid is locked. (3) There is a short "Humm-click" that comes from the bottom of the machine. (4) It won't continue into wash cycle and no "wash" light illuminated. (5) Drains normally if cycle is cancelled. (6) I watched YouTube videos on my exact model machine. It explained how to get into machine diagnostics (using 6 lights on front of control panel. (7) I successfully entered into diagnostic mode. Then self test. (8) I get 4 lights illuminating together and then 2 lights together. It keeps repeating. I didn't get any info on codes in my manual as the man in the video. (9) The 4 lights together are "sensing" "rinse" "spin" & "complete". (10) The 2 lights together are "rinse" & "complete". I know the machine is telling me something, but what???
