Viking Dishwasher Error Code 2-5

Error code 2-5 is a High Level Error indicating that the pressure sensor has detected water in the sump at a level above the programmed high threshold. The dishwasher stops operation as a protective measure to prevent overfilling or flooding. The fault can originate from actual excess water caused by improperly loaded dishes, a malfunctioning pressure sensor, or a defective main control board.

A reset may temporarily clear the error code, but if the underlying cause is still present, the fault will return once the dishwasher attempts another fill cycle. If the error was triggered by improperly loaded rack items, correcting the loading before restarting will likely resolve it. For hardware-related causes such as a failed pressure sensor or control board, a reset alone will not fix the problem.

Repair costs depend on which component is at fault. If the issue is simply improperly loaded dishes, there is no cost involved. Pressure sensor replacement typically falls in the range of $75 to $200 including parts and labor, while a main control board replacement can range from $200 to $500 or more depending on the part cost and service fees in your area. Getting a diagnostic inspection from a qualified technician will help identify the exact cause before committing to a repair.

Start by opening the dishwasher and checking whether any items in the rack are positioned in a way that traps or redirects water downward into the sump. Reposition cups, bowls, and deep containers so they drain freely. If the loading appears correct, the next steps involve testing the pressure sensor for accurate output and inspecting the main control board, which may require a qualified technician to complete properly.

You should not continue running the dishwasher while this error is active. The 2-5 code indicates a water level above the safe operating threshold, and running a cycle under that condition risks water overflow, potential flooding, or damage to internal electrical components. Diagnose and resolve the fault before resuming normal use.
