Viking Range Error Code 6

Error code 6 on a Viking range indicates a fault on the filter board. The cause can be corrupted or lost EEPROM data on the board, a permanent low voltage condition being detected, or a failure of an electronic component on the filter board. This is a control system fault that typically requires professional diagnosis and filter board replacement.

A power reset may temporarily clear the error, but if the underlying cause is a failed EEPROM, a hardware fault on the filter board, or a persistent low voltage condition, the code will return. A reset alone is not a fix for this error and should only be used as an initial diagnostic step to observe whether the fault is intermittent or permanent.

The total repair cost depends on whether the issue is a wiring or connection problem versus a full filter board replacement. If the filter board requires replacement, parts costs for Viking control boards typically fall in the range of $150 to $400 or more depending on the specific model, with additional labor charges if a technician performs the work. Diagnosing the voltage condition first can help avoid unnecessary parts replacement.

The first step is checking that the filter board is receiving the correct supply voltage, which requires a multimeter and comfort working around live electrical components. If the voltage is correct and the error persists, the filter board must be replaced. Filter board replacement involves working with control wiring and is best handled by a qualified appliance technician, though experienced DIYers comfortable with control board swaps may be able to perform the repair.

Error code 6 indicates a fault in the control system's filter board, which can affect how the range manages its electronic functions. Continued use is not recommended until the fault is diagnosed, as an underlying voltage problem or board failure could potentially affect other control systems or cause unpredictable behavior.
