Decided it could be 1 of 3 things. Fuse on main circuit board that controls hot water. Main control board or drain pump failure.

You can go on line and find videos on removing the circuit board for GE dishwashers. This can be done without pulling the dishwasher out. Remove the lower black dust panel and insulation. Remove cover to electrical box - 1 screw and remove. Remove 2 to 4 screw on a sheet metal bracket that holds the circuit board. Notice where 2 metal hangers are located if you remove 4 screws on the left and right side of machine as they drop out. Remove black corded door sensor under circuit board. Work the sheet metal back and forth to remove from dish washer so that circuit board is exposed. Remove circuit board connectors and pull out unit to install new circuit board. Some have one screw and some have only plastic retainers. Re-install. I did not need the drain pump and the circuit board comes with a control board fuse. Washer was only 14 months old and 2 months out of warranty.

Replaced floating seal. Un plugged and Pulled washer out from the counter and laid on its left side. Pull pump out of seal by hand. Straight screwdriver to lever seal out of fitting. Clean hole and wipe seal then push into hole. Reinsert pump reverse install.
To make it easier I previously extended the water supply hose to nearly 8 ... Read more feet so did not have to disconnect it.
