Error Code Explained
What Does the Viking Detergent Dispenser Fault Error Code Mean?
A Viking dishwasher detergent dispenser that fails to open during the main wash cycle results in dishes being washed with only pre-wash detergent or hot water — cleaning performance will be poor. The dispenser door is typically opened by a wax actuator or spring mechanism triggered by the control board at the correct point in the wash cycle.
