Problem: Our dishwasher used to stop mid-cycle, and the screen would display an error code, I believe it was OC. This would happen once or twice a week.
Solution: After adjusting the height of the drain hose, removing and cleaning the filter numerous times, the issue was resolved once we switched from the pod-type soap to liquid. Under fear of jinxing ourselves, I'll say it's been over a year since we've had any issues.
