Al for Model Number GDF620HGJ2BB Dishwasher would not start. Power cycling the dishwasher would get it working again but it lasted shorter and shorter times until that didn't work anymore. Replaced the UI board which didn't help and then replaced the main control board which also didn't fix it. No power at all to display or buttons. Service light on Main control board is solid green with both original and new main board - which isn't one of the listed choices on the service information sheet. (everything listed is flashing). . Thank you.
