Viking Dishwasher Error Code Counter Error - User Interface

This error means the user interface board has detected an internal logic fault in one of its processing counters. The UI board is responsible for managing all control panel functions and coordinating with the main control board. The fault prevents the dishwasher from operating normally until the counter state is reset or the board is repaired. It is not related to a sensor reading or a mechanical component failure.

The dishwasher will typically not operate while this error is active, so continued use is not immediately possible without first clearing the code. The error itself does not indicate a hazardous condition such as a water leak or electrical short. However, you should not attempt to bypass the error to force operation, as the UI board may not properly control the wash cycle. Perform a reset and verify normal operation before running a load.

Start by performing a hard reset and testing whether the error clears. If the error persists, visually inspect the UI board for signs of moisture, corrosion, or burn marks after carefully removing the door panel. Check that all wiring harness connectors to the UI board are fully seated and free of corrosion. If the board shows physical damage or the error continues after connector inspection, the board should be replaced.

A reset will clear the error in many cases, particularly if the fault was caused by a power fluctuation or temporary communication glitch. To reset, cut power to the dishwasher at the circuit breaker or unplug it for at least 60 seconds, then restore power. If the error does not return after the reset and the dishwasher completes a full cycle, no further action is needed. If the error comes back consistently, the UI board likely needs to be replaced.

If the issue is resolved by a simple reset, there is no parts cost involved. If the user interface board requires replacement, parts alone typically range from $100 to $300 depending on the specific model, with professional labor adding another $100 to $200 in most cases. Inspecting and reseating wiring connectors is a no-cost diagnostic step worth completing before purchasing any parts.
