Viking Dishwasher Error Code ECONO WASH + LED1

This error code indicates a Counter Error within the User Interface board. It means the UI's internal control logic has encountered an unexpected state or lost synchronization. The dishwasher stops operation to prevent running an incorrect or incomplete cycle. It is an electronics-level fault, not a plumbing or mechanical issue.

Start with a full power reset at the breaker. If the error persists, inspect the ribbon cable between the UI board and the main control board for loose connections or damage. Also check the UI board for signs of moisture, corrosion, or physical damage. If no connection issues are found and the error keeps returning, replacing the UI board is typically the solution.

If a simple reset resolves the issue, there is no parts cost. If the UI board requires replacement, parts alone typically range from around $80 to $250 or more depending on the specific model, with professional labor adding $100 to $200 on top of that. Inspecting and reseating the ribbon cable connection is a low-cost repair that can sometimes resolve the fault before committing to a board replacement.

A reset is the recommended first step and will clear the error if it was caused by a temporary glitch or power fluctuation. Turn off the circuit breaker for one to two minutes, then restore power and test. If the code returns after resetting, there is likely an underlying hardware problem with the UI board or its connections that requires further diagnosis.

The dishwasher will generally not operate normally while this error is active, so continued use is not possible until the fault is resolved. The error itself is not a safety hazard related to water or electrical shock in normal circumstances, but you should not attempt to bypass the fault. Resolving the underlying UI issue before running cycles is the correct approach.
