I'm from the boomer generation, so I have owned a number of dishwashers and this wasn't the first time I have had this happen. I immediately went to my computer and ordered both the spring and the cable door hinge assembly from AppliancePartsPros.com
The price for the parts was reasonable so since I wasn't sure which part broke, I just ordered both.
The parts were shipped the same day, however the shipping was a little high since could have been mailed for about half the price and I would have had the parts in the morning until having to wait for UPS to deliver in the late afternoon (not supplier fault though!).
Anyway, with the dishwasher, I only had to remove the bottom cover plate and the top mounting screws and pull dishwasher out about four inches. Removed the spring and the broken hinge cable and replaced them. The worst part was stretching the spring to connect the two parts. A pair of vice grips solved the problem. It took about 20 minutes to complete the repair.
