Viking Dishwasher Error Code NORMAL WASH + LED6

This code indicates a pressure sensor malfunction involving the HUBA sensor in your Viking dishwasher. The sensor monitors water pressure or water level during the wash cycle, and the control board has detected that the sensor signal is out of range or absent. The dishwasher will not complete its cycle until the fault is resolved.

You should not attempt to run the dishwasher while this fault is active. The pressure sensor helps the control board verify that water fill conditions are correct before and during operation. Running the appliance without a functioning sensor could result in improper water levels, potential overflows, or damage to heating components.

Repair costs will vary depending on whether the fault is a simple connector issue or requires a new HUBA pressure sensor or wiring harness. A sensor replacement, including parts and labor, typically falls in the range of $100 to $300. If the control board is involved, costs can be higher, often ranging from $200 to $500 or more depending on parts availability and labor rates in your area.

Start by inspecting the HUBA pressure sensor and its wiring harness for loose connectors, corrosion, or visible wire damage. Reseat any connectors that are not fully engaged. If the wiring checks out, the sensor will need to be tested electrically and replaced if it is faulty. In some cases, a damaged wiring harness or a control board issue may also be responsible.

A reset may temporarily clear the code, but if the underlying sensor or wiring fault has not been repaired, the code will return when the dishwasher attempts to run again. A reset alone is not a fix for a hardware fault in the HUBA pressure sensor circuit.
