Viking Dishwasher Error Code Pressure Sensor Disconnect

This error means the dishwasher control board has lost its connection to the HUBA pressure sensor, which monitors the water level inside the tub. Without this signal, the dishwasher cannot safely control the fill cycle and will stop operation. The cause is either a disconnected or damaged wiring harness, corroded connector terminals, or a failed sensor.

A reset may temporarily clear the error code from the display, but the fault will return as soon as the dishwasher attempts to run a cycle if the underlying issue has not been corrected. The harness connection and sensor condition must be addressed to resolve the error permanently.

If the repair only requires reseating a loose connector or cleaning corroded terminals, costs may be limited to a service call fee, typically in the range of $75 to $150. If the HUBA pressure sensor or wiring harness needs to be replaced, parts and labor combined can range from $150 to $350 or more depending on your location and the technician's rates.

Start by checking the HUBA pressure sensor harness connector to make sure it is fully seated and undamaged. Then inspect the harness wiring along its full run for chafing, pinches, or corrosion at the terminals. If the wiring checks out, the HUBA sensor itself will need to be tested and likely replaced.

Running the dishwasher with this error present is not recommended. The pressure sensor is responsible for monitoring the water level in the tub, and without a functioning sensor the control board cannot prevent an overfill condition. It is best to leave the unit off until the sensor or harness issue is resolved.
