Viking Range Error Code DSI 5 Flashes

The DSI 5 Flashes code indicates a fault within the Direct Spark Ignition control module. The module signals this by flashing 5 times every 4 seconds. It means the ignition control has detected an internal error and cannot operate normally. The first step is to cycle power to the range; if the code returns, the DSI module needs replacement.

When the DSI module is in a fault state, the ignition system may not operate reliably, meaning burners may not light or may not be monitored correctly during startup. It is best to avoid using the affected burners until the fault is diagnosed and resolved. If you smell gas at any point, turn off the gas supply and ventilate the area immediately.

Start by cycling power to the range. If the fault clears and does not return, an external electrical disturbance was likely the cause. If the code returns immediately, inspect the wiring and connectors to the DSI module for damage or loose connections, and verify that the module is receiving correct supply voltage. If the wiring and voltage check out and the 5-flash code persists, the DSI module itself is the failed component and should be replaced.

A power cycle is the recommended first step and can clear the fault if it was triggered by a transient electrical event. To reset, disconnect power to the range for at least 30 seconds and then restore it. If the 5-flash code reappears after the reset, the DSI control module has a permanent internal fault and resetting will not resolve it.

If the fix is simply a power cycle, there is no parts cost involved. If the DSI control module requires replacement, parts alone typically range from around $80 to $250 or more depending on the specific model. Adding professional labor, total repair costs generally fall in the range of $150 to $400. Getting a firm quote from a technician before authorizing the repair is recommended.
