Viking Dishwasher Float Switch Overfill Fault

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.

Root Causes

What Causes the Float Switch Fault Error?

Float Stuck in Raised Position

Debris or detergent residue under the float dome has caused the float to stick in the raised (overfill detected) position, preventing water from entering the tub.

Failed Float Switch

The micro-switch operated by the float has failed in the tripped (overfill) position.

Troubleshooting Steps

Basic Steps Before Calling a Technician
