Viking Dishwasher Error Code Data processor

The Data processor error means the main control board has detected an internal fault in its microprocessor or logic circuitry. It is not a sensor or motor error but rather a problem originating inside the board itself. The dishwasher stops operation to prevent unpredictable behavior. A power reset is the first recommended step.

Start by cutting power to the dishwasher at the circuit breaker for one to two minutes, then restore power and run a test cycle. If the error clears and does not return, no further action is needed. If the error persists, the control board is the primary suspect and will need to be replaced by a qualified technician, as internal processor faults cannot be repaired at the component level in the field.

If the error is resolved by a simple power reset, there is no parts cost involved. If the control board needs replacement, parts and labor costs typically range from several hundred dollars to over five hundred dollars depending on the specific model and local labor rates. Obtaining a diagnostic visit from an authorized technician is the best way to confirm whether board replacement is necessary before committing to that expense.

A power reset at the circuit breaker, held for at least one to two minutes, will sometimes clear this error if it was caused by a temporary power fluctuation or a one-time firmware glitch. If the error returns immediately after restoring power, the reset did not resolve the underlying issue and the control board should be inspected or replaced. Repeated resets without a lasting fix indicate a hardware fault inside the board.

When this error is active, the dishwasher will typically not operate, which is a built-in protective response. You should not attempt to force a cycle while the error is present. Restoring power after a reset and observing whether the machine runs normally is the appropriate approach before using the appliance again.
