Viking Dishwasher Error Code 2-3

Error code 2-3 means the user interface board and the main control board have lost communication with each other. The dishwasher cannot operate safely without this link, so it shuts down and displays the code. The fault is usually caused by a loose connector, a broken wire, or a failed board.

A reset may temporarily clear the code, but if the underlying wiring or component problem is not corrected, the error will return as soon as the dishwasher attempts to operate again. A reset is useful for confirming whether the fault is intermittent, but it is not a repair.

If the issue is simply a loose connector, the repair may cost nothing beyond a service call fee, which typically ranges from $75 to $150. If a board replacement is needed, parts alone can range from $100 to $400 or more depending on which board has failed, with total repair costs including labor potentially reaching $300 to $600 or higher.

If you are comfortable working around appliance wiring, you can start by checking the wiring harness that connects the user interface to the main control board. Reseating loose connectors or cleaning corroded pins requires no special tools and may resolve the issue. If the wiring is intact, board replacement is typically a job for a qualified technician.

No. When this code is active, the dishwasher has disabled itself because the control boards cannot communicate. Attempting to force operation is not recommended. The appliance should remain off until the fault is diagnosed and corrected.
