Hello - Our dishwasher was not starting after selecting the wash settings. The user panel appears to work fine, takes all input. Upon closing the door the start button LED and the LED on the front would just blink, no pattern. Confirmed through diag mode that the door registers open by all the LED's on the panel flashing when open. Upon closing in this mode the LED's stop blinking and go out. I ordered a door latch, but not very confident it will fix the issue. I then looked at the controller board located under the unit to see if the service LED was blinking to cross reference to the technical service guide. The LED is not lit up at all. So now I'm wondering if the controller board under the unit is bad. Any help on this would be appreciated. Thank you.
