Viking Dishwasher Error Code 3-5

Error code 3-5 indicates a motor undervoltage condition and is specific to Viking 325E and 450E dishwasher models. The motor control board has detected that the voltage available to the motor circuit is below acceptable levels. The dishwasher stops operation to protect the motor from potential damage caused by running at insufficient voltage.

A reset may temporarily clear the fault display, but if the underlying voltage issue has not been resolved, the error will return once the dishwasher attempts to run the motor again. Resetting is a useful first step to confirm whether the fault is persistent, but it is not a fix for the root cause.

Repair costs depend on the root cause. If the issue is a loose wiring connection or a tripped breaker, the cost may be minimal, covering only a service call fee in the range of $75 to $150. If the motor control board requires replacement, parts and labor combined can range from $200 to $500 or more. Drive motor replacement on these models typically falls in a similar or higher range depending on labor rates in your area.

Start by measuring the supply voltage at the dishwasher's power source to confirm it is within the required specification. If supply voltage is correct, inspect all wiring connections to the motor and motor control board for looseness or corrosion. If wiring and supply voltage both check out, the motor control board or drive motor may need to be tested and potentially replaced.

The dishwasher is designed to halt operation when this code appears, so running a cycle is typically not possible until the fault is addressed. Do not attempt to bypass the error, as operating a motor under low voltage conditions can cause overheating and permanent motor damage. Have the supply voltage and internal components inspected before returning the unit to service.
