I started by removing the screws from the inside of the door. Unfortunately I removed too many,
which released the door from the spring loaded hinges….Ugggg! I realized I didn't have to remove
the door just the top section of the door where the control unit lives.
After replacing the spring loaded hinge back to the door by myself which was not easy task.
I accessed the top of dishwasher where the new unit lives and replaced the unit. It was actually not that bad . Removing the too many screws was!!!
But the good news, the dishwasher works. Yippee!!!
