left door spring broken - door wouldn't stay up

Removed the two screws securing the dishwasher to the underside of countertop.
Pulled the washer out until the spring mechanism was visible. Vacuumed the area - it was filthy. Assembled the spring and adjusting hook. Took me 4 tries to get the spring into the proper tension slot. Having the other side intact helped in understanding how it worked. Used long nosed pliers to bring spring onto the door retaing plate slot after trying unsuccessfully with regular pliers.
