Viking Dishwasher Error Code NORMAL WASH + LED2

This error code indicates a Pressure Sensor Disconnect fault. The control board has lost its connection to the HUBA pressure sensor, which monitors water level in the tub during the wash cycle. The fault is tied specifically to a harness connection failure between that sensor and the board. The dishwasher will not operate normally until the connection issue is identified and corrected.

A power reset may temporarily clear the error display, but the fault will return if the underlying harness connection problem has not been fixed. Because this code reflects an active electrical disconnect rather than a one-time glitch, the physical connection to the HUBA sensor must be inspected and corrected to resolve the error permanently.

If the fix is simply reseating a loose harness connector, there may be no parts cost at all, with any expense limited to a service call fee, which typically ranges from $75 to $150 depending on your location. If the harness or HUBA pressure sensor needs replacement, total repair costs including parts and labor generally range from $150 to $350. Costs vary based on local labor rates and parts availability.

Start by locating the HUBA pressure sensor and inspecting its wiring harness connection at both the sensor end and the control board end. Press each connector firmly to ensure it is fully seated and check the terminals for corrosion or damage. If the connectors look clean and secure but the fault remains, the harness or the pressure sensor itself may need to be tested for continuity and potentially replaced.

Running the dishwasher while this fault is active is not recommended. The pressure sensor is responsible for monitoring water level, and without reliable sensor input, the control board cannot properly regulate the fill cycle. This could lead to underfilling or overfilling conditions that may affect wash performance or potentially cause water-related issues.
