Door won't stay up and door leaking on floor

Replacing the door bottom gasket is a breeze, just grasp with a needle nose pliers and pull out. I positioned a small mirror inside the dishwasher so I could see where the gasket fit back in. I pushed the new gasket into the slot and ----done.
The springs require that the dishwasher be pulled out from its opening after removing the screws holding it into the cabinet at the top of the dishwasher. Replacing the springs is easy, just remove the old ones from the the bottom frame holes and the plastic holder and put the new ones on through the plastic holder and then into the frame. Push the dishwasher back into its opening, square it with the cabinet and reinstall the mounting screws.
