Viking Dishwasher Error Code State Error - Main Control

This error means the main control board has entered an operating state it does not recognize and cannot continue from. The board manages all cycle sequencing, and when it loses track of its position in that sequence or receives conflicting input signals, it halts and displays this error. It can result from a power interruption, a wiring issue, or in some cases a board that has failed.

If a power reset does not resolve the error, the next steps are to inspect the wiring harness connections at the main control board for looseness or corrosion, test the door latch switch for proper continuity, and check for any failing sensors or motors sending bad feedback signals. If all connected components test properly, the main control board itself may need to be replaced.

Repair cost depends on the root cause. If a simple reset resolves the issue, there is no parts cost at all. A door latch or switch replacement typically falls in the range of $30 to $100 for parts. If the main control board needs replacement, parts and labor combined can range from $200 to $500 or more depending on your location and service rates.

A reset is the recommended first step and will clear the error in many cases, particularly when a power fluctuation caused it. Turn off the dishwasher at the circuit breaker, wait one to two minutes, then restore power and run a test cycle. If the error returns during or immediately after the cycle, a deeper electrical or component issue is likely present.

No, you should not attempt to operate the dishwasher while this error is active. The control board has stopped the cycle intentionally to prevent uncontrolled operation. Running the machine with an unresolved control fault could lead to improper fill, failure to drain, or other mechanical issues.
