For this washing machine the error is most frequently the Washer Door Lock Assembly (part number 131763202 ), and I had already replaced this part three years ago. Since the LEDs and beeping sounds were going crazy with no sensible or recognizable pattern I could not troubleshoot according to the established procedure in the manual. So I ordered another door lock assembly without attempting to troubleshoot further. Turned out to be a waste as it was not the door lock assembly. Surfing your web site and looking at some of the other peoples experiences I noticed one where the person had a similar problem with the LEDs and beeping sounds flashing and sounding off randomly. He said that the controller board (part number 137005000), was what finally fixed his washer. IMPORTANT: - Be extremely careful to make notice of the positions of the front panel knobs before removing the controller board from the back of the front panel. Also be very careful when holding the front panel after removing the controller board from it as the small front panel push button switches and their associated springs will go flying.
