What 6 flashes (DSI) means on a Viking range

On a Viking range, 6 flashes from the DSI (Direct Spark Ignition) control module indicates a gas solenoid fault. The DSI system controls the ignition sequence for the oven burner, and a core part of that sequence involves energizing the gas valve solenoid to allow gas flow after a spark is established. When the control detects that the solenoid circuit is not responding correctly, either due to an open circuit, a short, or a failure within the valve itself, it terminates the ignition attempt and signals the fault with 6 consecutive LED flashes.

The gas solenoid is an electrically operated valve coil that opens the gas valve when it receives the correct voltage signal from the DSI board. If the wiring harness between the DSI module and the solenoid is damaged, corroded, or has a loose connection, the solenoid will not receive a proper signal and the fault will trigger. Similarly, if the solenoid coil itself has failed internally, the DSI board will detect the abnormal load condition and lock out.

Diagnosis should begin with a visual inspection of the wiring and connectors between the DSI module and the gas valve solenoid, looking for burnt insulation, corrosion, or pulled terminals. From there, the solenoid coil resistance should be measured to confirm whether the coil is within spec or has opened or shorted. A failed DSI board that is incorrectly reading a good solenoid circuit is a less common but possible root cause.

Common causes of 6 flashes (DSI)

  1. 01

    Faulty or failed gas solenoid coil

    Part replacement

    The solenoid coil inside the gas valve can open or short over time, preventing it from operating when energized. Measuring the coil resistance will reveal an out-of-spec or infinite reading if the coil has failed.

  2. 02

    Damaged or disconnected wiring harness

    Wiring / connection

    Wiring between the DSI module and the gas valve solenoid can be burned, corroded, or have loose terminal connections, breaking the circuit. A visual inspection and continuity test of the harness will identify this issue.

  3. 03

    Corroded or loose connector terminals

    Wiring / connection

    Connector pins at the solenoid or DSI board can oxidize or back out of their housings, creating an intermittent or open circuit. Reseating or cleaning the connectors may resolve the fault without parts replacement.

  4. 04

    Failed DSI ignition module

    Part replacement

    If the wiring and solenoid both test correctly, the DSI control board itself may be misreading the solenoid circuit or failing to send the proper output signal. This is less common but requires replacing the DSI module.

  5. 05

    Gas valve failure

    Part replacement

    In some cases the gas valve assembly as a whole has failed mechanically or electrically, beyond just the solenoid coil. This requires full gas valve replacement and should be handled by a qualified technician.

Frequently asked questions about 6 flashes (DSI)

What does 6 flashes (DSI) mean on a Viking range?
Six flashes on the DSI module of a Viking range indicates a gas solenoid fault. The Direct Spark Ignition system detected a problem with the solenoid circuit that controls gas flow to the oven burner. As a safety response, the system locks out ignition until the fault is resolved. The problem is typically found in the solenoid wiring, the solenoid coil itself, or the gas valve.
Can I fix a Viking range 6-flash DSI fault myself?
A knowledgeable DIYer can safely inspect and test the wiring harness and connector terminals between the DSI board and the gas solenoid. However, any work involving the gas valve itself should be performed by a qualified appliance technician, since improper handling of gas components creates a serious safety risk. If wiring checks out and the solenoid coil or gas valve needs replacement, professional service is strongly recommended.
Is it safe to use my Viking range when it shows a 6-flash DSI fault?
The oven should not be used while this fault is active. The DSI system has locked out ignition specifically because it detected an abnormal condition in the gas solenoid circuit. Attempting to bypass or ignore the fault while the gas valve is not operating correctly could result in incomplete ignition or unsafe operating conditions. Surface burners with separate ignition systems may still function, but the oven should remain off until the fault is repaired.
Will resetting my Viking range clear the 6-flash DSI fault?
A power reset, such as unplugging the range or cycling the breaker, may temporarily clear the fault and allow an ignition attempt. However, if the underlying problem with the solenoid wiring or coil is still present, the fault will return immediately or after a short time. A reset is useful as a first step to confirm the fault is active and repeatable, but it is not a repair.
How much does it cost to repair a Viking range DSI gas solenoid fault?
Repair costs vary depending on whether the issue is a wiring problem or a parts replacement. If only wiring or connectors need attention, labor costs alone may range from around $100 to $200. If the gas valve or DSI module requires replacement, parts costs can add $150 to $400 or more depending on the specific components, plus labor. Getting a diagnosis from a certified technician before committing to parts is the most cost-effective approach.
