Viking Cooktop Error Code 6

Error code 6 on a Viking cooktop indicates a fault on the filter board, which manages low-voltage power for the unit's electronics. The code covers three related conditions: sustained low voltage output from the filter board, a failed electronic component on the board, or lost or corrupted EEPROM data. The diagnostic starting point is verifying that the voltage supplied to the filter board is correct, and if it is, replacing the filter board.

Error code 6 indicates a failure in the control electronics power and memory system, which means the cooktop may not operate reliably or safely. It is not advisable to continue using the cooktop while this fault is active. Discontinue use and have the unit diagnosed before operating it again.

Repair costs depend on the exact cause identified during diagnosis. If only a wiring or connection issue is found, the cost is primarily labor, typically in the range of $100 to $200. If the filter board requires replacement, parts and labor combined can range from $200 to $500 or more depending on the specific model and local labor rates. Getting a diagnostic estimate from a certified Viking technician before authorizing repairs is recommended.

Checking the supply voltage requires electrical testing skills and appropriate safety precautions, so it is generally a task for a qualified appliance technician. If the voltage supply is confirmed good and the filter board needs replacement, sourcing the correct board and installing it involves working inside the cooktop's electrical components. DIYers with solid electrical knowledge may be able to handle the voltage check, but board replacement on a gas or induction cooktop is best left to a professional.

A simple power reset is unlikely to resolve error code 6 on a Viking cooktop. Because the fault involves either hardware failure on the filter board or corrupted EEPROM memory, the underlying problem remains after power is restored. The error will typically return immediately on startup unless the root cause is repaired.
