Viking Dishwasher Error Code Cycle Error - Motor Controller

This error means the dishwasher's internal control processor detected a problem with the motor controller circuit during a wash cycle and stopped operation as a protective measure. The motor controller regulates power and operation of the wash pump motor, so any communication failure or out-of-range condition between the processor and that circuit triggers this fault. It can result from a simple power glitch, a wiring issue, a failing control board, or a problematic wash pump motor.

Start with a power reset and test cycle. If the error persists, inspect all wiring harness connections at the control board and wash pump motor for corrosion, looseness, or damage. If connections are intact, the fault likely lies with the main control board's motor controller circuit or the wash pump motor itself, both of which would require component replacement. A qualified technician can test the motor's resistance and board output to confirm which part has failed.

Repair costs vary depending on the failed component. If only a wiring connection needs to be cleaned or reseated, costs may be limited to a service call fee, typically in the range of $75 to $150. Replacement of the main control board generally falls in the range of $200 to $500 or more including parts and labor, while wash pump motor replacement can range from $150 to $400 depending on parts availability and labor rates in your area.

A power reset is the correct first step and will clear the error if it was caused by a transient voltage spike or temporary processor glitch. Disconnect the dishwasher from power for one to two minutes, restore power, and run a test cycle. If the error returns, the underlying cause is a hardware problem that requires further diagnosis and will not be resolved by repeated resets.

It is not advisable to continue running the dishwasher while this error is active. The control processor halts the cycle specifically to prevent potential damage to the motor or motor controller circuit. Running the unit repeatedly through forced restarts without addressing the root cause could worsen an existing motor or board failure and lead to a more costly repair.
