Viking Range Error Code DSI 2 Flashes

The DSI 2 Flashes code means the Direct Spark Ignition control module has detected an internal fault and is signaling it with two flashes every four seconds. The DSI control manages the gas ignition sequence for the burners. When this fault is active, the ignition system will not operate normally. The code points specifically to the control module rather than to the igniter or gas valve.

Start by cycling power to the range completely and allowing it to reinitialize. If the fault code clears and the range ignites normally, no further action is needed. If the two-flash code returns, the DSI control module must be replaced. Before replacing the module, it is worth inspecting the wiring connections at the board for looseness or corrosion, as a connection issue can sometimes trigger a fault.

If the DSI control module requires replacement, parts costs typically range from around $150 to $350 or more depending on the specific model, with professional labor adding another $100 to $200 in most cases. If the fault was caused only by a power surge and clears after a reset, there may be no parts cost at all. Getting a quote from a qualified technician after diagnosis will give you the most accurate estimate for your specific unit.

A power cycle is always the recommended first step and can clear the fault if it was triggered by a temporary electrical event. To reset, turn off the range and disconnect power for several minutes before restoring it. If the two-flash pattern returns after the reset, the DSI control module has a persistent internal fault and will need to be replaced.

Operating the range with an active DSI fault is not recommended. The DSI control governs the ignition sequence and gas valve behavior, and a faulted module means those functions may not work correctly or predictably. Until the fault is resolved, the burners may fail to light or may not sequence properly, creating a potential gas accumulation risk.
