Error Code Explained
What Does the Viking Float Switch Fault Error Code Mean?
Viking dishwashers use a float switch at the bottom of the tub as an overfill safety device. When the water level exceeds a safe threshold, the float rises and the switch cuts power to the inlet valve. A float switch that is stuck in the raised position will prevent the dishwasher from filling at all — the machine will start but the tub will remain empty. A stuck-down float allows overfilling.
