Viking Dishwasher Error Code Moisture Sensor Disconnect

This error means the control board is detecting an open circuit in the moisture sensor loop, indicating the sensor is either physically disconnected or has failed internally. The control board cannot receive a valid signal from the sensor. The fault must be resolved before normal operation can resume.

It is generally not recommended to continue running the dishwasher while this fault is active, as the control board is missing sensor input it relies on to manage the cycle properly. Operating with a disconnected sensor circuit could result in incomplete or improper cycle behavior. Resolve the fault before resuming use.

Performing a reset may temporarily clear the error code, but the fault will return as soon as the control board checks the sensor circuit again and detects the open condition. A reset is not a repair. The underlying cause, whether a loose connector, damaged wire, or failed sensor, must be corrected to permanently resolve the error.

In many cases, yes. Start by checking the wire connector at the moisture sensor and reseating it firmly, then inspect the harness for any visible damage or broken wires. If connections are intact but the error persists, testing the sensor for continuity with a multimeter can confirm whether the sensor itself needs replacement. If the control board connection or the board itself is involved, that repair is better suited to a qualified technician.

If the fix is simply reseating a loose connector, there is no parts cost and only a service call fee if a technician is involved, typically in the range of $75 to $150. Replacing the moisture sensor itself usually runs $50 to $150 for the part, plus labor. If the wiring harness or control board requires replacement, total repair costs can range from $200 to $500 or more depending on parts and labor rates in your area.
