Viking Dishwasher Error Code 1-1

Error code 1-1 on a Viking dishwasher indicates a moisture sensor disconnect, meaning the moisture sensor located in the base pan is reading outside its normal expected range. This can be caused by a disconnected wire, a faulty sensor, actual water leaking into the base pan, or a defective control board. The dishwasher uses this sensor to detect leaks beneath the tub, and any out-of-range reading will trigger this code.

It is not recommended to continue running the dishwasher while this code is active. The 1-1 code is designed to alert you to a potential leak condition, and ignoring it could allow water damage to the floor or cabinetry beneath the appliance. Inspect the base pan for water before attempting any further use.

Repair costs depend on which component is at fault. If only a wiring reconnection is needed, costs are primarily labor and could be relatively modest. A replacement moisture sensor typically adds a modest parts cost on top of labor. If the control board needs replacement, parts alone can range from several hundred dollars upward, making it one of the more expensive possible outcomes for this fault code.

A knowledgeable DIYer can start by checking for water in the base pan and inspecting the wiring connections to the moisture sensor for loose or disconnected terminals. If the connections are secure and no water is present, testing or replacing the moisture sensor is the next step. Control board diagnosis and replacement are more complex and are generally better handled by a qualified technician.

A reset may temporarily clear the code, but it will return if the underlying issue has not been resolved. If the moisture sensor wiring is disconnected, the sensor has failed, or there is water in the base pan, the fault condition still exists and the code will reappear. Always address the root cause rather than relying on a reset.
