Viking Range Error Code 5 flashes (DSI)

Five flashes on a Viking range indicates a fault with the DSI, or Direct Spark Ignition, control module. This is the electronic board that manages the ignition sequence for gas burners or the oven. The fault means the DSI control has detected an internal error or lock-out condition it cannot clear on its own. Viking's diagnostic procedure calls for a power cycle first, followed by DSI board replacement if the fault persists.

Start by cycling power to the range at the circuit breaker and retrying ignition. If the 5-flash fault comes back, inspect the wiring connections at the DSI control board for loose or damaged terminals. If connections are intact and the fault persists, the DSI control module requires replacement. This repair involves working with gas appliance components, so a qualified technician is recommended if you are not experienced with range repairs.

If only a power cycle is needed, there is no parts cost. If the DSI control board requires replacement, parts costs typically range from around $150 to $400 or more depending on the specific Viking model. Adding professional labor for diagnosis and installation, the total repair cost generally falls in the range of $250 to $600. Costs vary based on your location and the service provider.

A power cycle will clear the fault if the cause was a temporary lock-out or a power irregularity. Turn the range off at the circuit breaker, wait at least 30 seconds, and restore power. If the 5-flash code returns after the reset, the DSI control board has an internal fault and will need to be replaced.

Using the range while the DSI fault is active is not advisable. The DSI module controls the ignition sequence and gas valve timing, and a faulty board may not reliably light the burner or may not properly manage gas flow. Continuing to attempt ignition with a faulting DSI control introduces a safety risk until the issue is diagnosed and resolved.
