Machine Info: Kenmore Elite Dishwasher, Model 665.12789K312, Stock No. 12789K, Type No 582-2. Part number on the control board itself is W10669042 Rev A and the part number on the control board's plastic housing is W10643059 Rev B, software W10747107DWS10.00. I noticed the screw holding down the plastic board cover was missing and I bought the machine second hand a while back so someone may have been in there before I got it.
Issue: Dishwasher ran overnight, dishes inside were all clean and dry so it seems to have completed the cycle. However, 6 red LEDs flash simultaneously in approximately one second intervals without any pauses and do so indefinitely. They are "2-4-8 Hr Delay" + "2 HR" + "4HR" + "8HR" + "CANCEL" and "LOCKED." The control panel does not respond to any inputs, including the commands to launch diagnostic mode. I have not seen this exact condition listed anywhere.
Troubleshooting so far: I removed power for one hour to no avail. All cables and connections to the control board have been checked for continuity and verified secure. No signs of corrosion anywhere. Based on the service manual, I checked for 13VDC across P12-2 (ground) and P9-6 and found it bouncing between 7 and 12VDC. Checked for 3.3VDC across P12-2 and P11-2 and found it bouncing between 0 and 0.5VDC. I noticed the fluctuations in the voltage are very closely timed to the flashing of the LEDs, though I am not sure if that is just coincidental.
Any help would be appreciated as we have a family and a lot of dishes! I do not mind replacing the board but want to be sure that is the root of the problem as it is expensive. Thanks.
