Viking Range Error Code DSI 3 Flashes

DSI 3 Flashes indicates an ignition lockout on a Viking range. The Direct Spark Ignition control attempted to light the burner multiple times and was unable to detect a flame within the allowed trial period. As a safety measure, the control board shuts down and locks out further ignition attempts. The underlying cause is typically a gas supply issue, a problem with the spark electrode or lead, or a faulty gas solenoid valve.

Yes, this error should be taken seriously because it means the range detected an ignition failure and shut down to prevent unburned gas from accumulating. Do not attempt to manually force the burner to light repeatedly. If you smell gas at any point, turn off the gas supply to the appliance and ventilate the area before doing anything else. Once the fault is resolved, the control system will resume normal operation.

Repair cost depends on which component has failed. If the fix involves cleaning or repositioning the electrode, a service call alone may be sufficient, typically ranging from $80 to $150 depending on your area. Replacing a spark lead or electrode can add $30 to $80 in parts. A gas solenoid valve or ignition control board replacement will generally bring the total repair cost into the $200 to $500 range including labor, with control boards on the higher end of that range.

Start by confirming that the gas supply valve is fully open and that other gas appliances in the home are working normally. Next, inspect the spark electrode for correct positioning and clean any grease or debris from around it. Check the spark lead for visible cracks or loose connections at both ends. If gas flow and the ignition components appear intact, the gas solenoid valve or control board may need to be tested and replaced by a qualified technician.

Cycling power to the range may clear the lockout temporarily and allow the ignition sequence to run again, but if the underlying fault is still present, the error will return after another failed ignition attempt. A reset is useful for confirming whether the fault is intermittent, but it does not fix the root cause. Persistent 3 Flashes errors require component-level diagnosis and repair.
