My GE dishwasher (10 years old) washes fine but recently stopped draining. The model # is GSD500L-01AW. We have hard water. Before,sometimes the water fills up in the sink when it is in a cycle then drains out. The only recent changes that have occured is that I started using Lemi Lime shine with my regular cascade detergent to stop the foggy glasses. it worked really well. I have never soaked it in vinigar or cleaned it so I did that yesterday and it still is not draining.
