Viking Dishwasher Error Code NORMAL WASH + LED6

The NORMAL WASH + LED6 error code on a Viking dishwasher indicates a pressure sensor malfunction, specifically involving the HUBA pressure sensor. This sensor is responsible for monitoring water pressure or water level within the dishwasher tub, sending electrical signals to the control board so the machine knows when the correct amount of water has entered or when conditions are safe for heating and washing cycles to proceed. When the control board receives a signal from the HUBA sensor that falls outside expected parameters, or receives no signal at all, it halts the wash cycle and triggers this fault code.

The HUBA sensor is an electromechanical component that converts pressure into an electrical output. A malfunction can stem from a failed sensor internally, meaning the component itself has degraded or shorted, or from issues in the wiring harness connecting the sensor to the control board. Damaged connectors, corroded terminals, or broken wires along that circuit can produce the same fault as a completely failed sensor. Water intrusion into the connector housing is another common culprit in dishwasher environments.

Diagnosing this code should begin with a physical inspection of the HUBA pressure sensor and its wiring harness. Check that all connectors are fully seated and free of corrosion or moisture damage. If the connections appear sound, the sensor itself should be tested for proper electrical output. If the sensor is confirmed faulty, replacement is required, as this component cannot typically be repaired in the field.
