Viking Dishwasher Error Code Flash both LED1 and LED2 continuously

This continuous dual LED flash indicates that the moisture sensor in the base pan of the dishwasher has detected water or a signal equivalent to water being present beneath the tub. The control board shuts down operation to prevent water damage. The fault points to either an actual water leak inside the unit or a defective moisture sensor producing a false reading.

No, you should not continue operating the dishwasher while this fault is active. The error indicates a possible active water leak that could damage your flooring, cabinetry, or electrical components beneath the unit. The dishwasher disables itself for this reason, and running it again before the fault is resolved risks worsening any existing water damage.

Repair costs vary depending on what caused the leak. Replacing a door gasket typically runs in the range of $50 to $150 in parts and labor, while a pump seal or inlet valve repair can range from $100 to $300 or more depending on parts and service rates in your area. If only the moisture sensor has failed and no actual leak is present, sensor replacement is generally a lower-cost repair, though labor costs for accessing the base pan area should be factored in.

Start by pulling the dishwasher out and inspecting the base pan for standing water. If water is present, trace the source of the leak by checking the door gasket, pump seals, inlet valve connections, and hose fittings, then repair or replace the faulty component. After removing all water from the pan and drying the area thoroughly, the sensor should clear once the pan is dry. If the pan is dry but the error persists, the moisture sensor or its wiring harness should be tested and replaced if found defective.

A reset will not permanently clear this error if the underlying cause is still present. As long as water remains in the base pan or the moisture sensor continues to output a water-detected signal, the fault will return as soon as the unit attempts to operate. The physical cause, either the source of the leak or the faulty sensor, must be addressed before the error will stay cleared.
