Samsung dishwasher Waterwall reflector error code 7E or 7C
The Waterwall reflector error (7E or 7C) occurs on your dishwasher when the WaterWall reflector is unable to move. This means something is blocking or holding it in place. It can also happen if it has not been reattached correctly. This can be easily fixed by removing obstructions and reattaching the reflector correctly.
