Viking Dishwasher Error Code 2-3 (service cycle only)

Error code 2-3 on a Viking dishwasher indicates a drain pump error in which the control board has detected that the drain pump current reading is outside the normal operating range. This code is generated during the service diagnostic cycle rather than during a standard wash cycle. It signals an electrical fault in the drain pump circuit, which could involve the wiring, the pump motor, or the control board.

Error code 2-3 appears only during the service diagnostic cycle, so you may not see it during normal operation. However, the underlying drain pump fault means the dishwasher may not drain water properly, which could result in standing water in the tub. It is best to address the fault before continuing regular use to avoid potential water damage or further component stress.

Repair costs vary depending on the failed component. Reconnecting a loose wiring connector requires no parts and only a service call fee, which typically ranges from around $75 to $150. Replacing a drain pump motor can cost between $150 and $400 including parts and labor, while a main control board replacement tends to run between $200 and $500 or more depending on parts availability and labor rates in your area.

Start by inspecting all wiring connectors between the main control board and the drain pump for any that are loose or disconnected, as this is the most common cause. If the connectors are secure, check the wiring harness for damaged or corroded wires and test the drain pump motor windings for proper resistance using a multimeter. If the wiring and pump motor both check out, the main control board may need to be evaluated or replaced.

Resetting the dishwasher may temporarily clear the fault code, but if the underlying cause is still present, the code will return when the service cycle is run again. A reset does not repair a disconnected wire, a faulty pump motor, or a damaged harness. The root cause needs to be diagnosed and corrected for the error to be permanently resolved.
