Viking Dishwasher Error Code POTS PANS + LED6

This error code indicates a Motor Control Communication Error, meaning the motor controller and the main control board have lost their communication link. The dishwasher stops operation when this happens to prevent damage to the motor or control electronics. Diagnosis starts with checking the wiring harness that connects these two components.

A power reset may temporarily clear the error code, but if the underlying communication fault between the motor controller and the main control board still exists, the error will return once the dishwasher attempts to run a cycle again. A reset is useful for confirming whether the fault is intermittent, but it does not fix the root cause. Proper diagnosis of the harness and control components is necessary for a lasting repair.

Repair costs depend on which component has failed. If the issue is simply a loose or damaged harness, repair costs may only involve a service call fee, typically in the range of $75 to $150. Replacing a motor controller or main control board involves both parts and labor, with total costs commonly ranging from $200 to $600 or more depending on parts availability and local labor rates.

A homeowner comfortable with basic appliance repair can check and reseat the wiring harness connections between the motor controller and the main control board, which resolves the error in some cases. However, if the harness is intact and the error persists, diagnosing and replacing the motor controller or main control board requires technical knowledge and familiarity with dishwasher electronics. At that stage, calling a qualified appliance technician is recommended.

You should not continue operating the dishwasher while this error is present. The motor controller and main control board cannot communicate reliably, which means the wash motor may not be managed correctly during a cycle. Running the unit in this condition risks further damage to the motor or control electronics.
