Viking Dishwasher Error Code LED1+LED2 flash continuously

This code means the moisture sensor in the base pan beneath the dishwasher tub has detected water or is outputting a signal equivalent to water detection. The dishwasher stops operating as a protective measure. The cause is either an actual water leak into the base pan or a defective moisture sensor producing a false reading.

No, you should not continue operating the dishwasher while this code is active. The alert indicates potential water accumulation beneath the unit, which can cause damage to flooring, cabinetry, and the dishwasher itself. Running the appliance with an active leak could make the underlying problem significantly worse.

Repair costs depend on the cause. If the issue is a clogged drain or residual moisture with no parts needed, you may only pay a service call fee, typically in the range of $75 to $150. Leak repairs involving gaskets or hose replacements can run $150 to $350 depending on the component. Moisture sensor replacement, including parts and labor, generally falls in the $100 to $250 range.

Start by pulling the dishwasher forward and inspecting the base pan for standing water. If water is present, find and repair the leak source, then dry the pan completely. If the pan is dry and the code still appears, the moisture sensor itself should be tested and replaced if it is faulty. A qualified technician should handle internal component access and sensor replacement.

A reset will not permanently clear this code if the underlying condition still exists. If water remains in the base pan or the moisture sensor is still detecting moisture, the code will return immediately or as soon as the machine attempts to run. The root cause, whether a leak or a defective sensor, must be resolved first.
