Viking Dishwasher Error Code 4-4

Code 4-4 on a Viking dishwasher signals an inlet valve current sense error, meaning the control board detected that the electrical current to the water inlet valve is outside its acceptable range. This error is generated during the service diagnostic cycle, not during a standard wash. It points to a problem with the inlet valve itself, the wiring connecting it to the control board, or the board's current sensing circuit.

Code 4-4 is generated only during the service diagnostic cycle, so your dishwasher may still complete normal wash cycles. However, the underlying wiring or valve fault could worsen over time, potentially leading to a no-fill condition or water control issues. It is advisable to have the problem diagnosed before continuing regular use.

Repair costs depend on the root cause. Reseating a connector costs nothing beyond a service call fee, which typically ranges from $75 to $150. Replacing an inlet valve generally costs between $100 and $250 for parts and labor combined. If the main control board needs replacement, total costs can range from $300 to $600 or more depending on parts availability and labor rates in your area.

A knowledgeable DIYer can start by inspecting and reseating the wiring connectors between the main control board and the inlet valve, since a loose or disconnected connector is the most common cause. If the connectors look fine, testing the inlet valve solenoid with a multimeter is a reasonable next step. Replacing a wiring harness or the control board is more involved and may be better suited to a qualified technician.

Resetting the dishwasher may temporarily clear the code from the display, but it will not resolve the underlying electrical fault with the inlet valve circuit. The code will return the next time the service diagnostic cycle is run if the root cause has not been corrected. A proper repair of the wiring or the inlet valve is required for a lasting fix.
