Code 1-2 is a motor control status or motor current fault on the wash motor.
Model compatibility: Viking reuses codes across series and model years, so 1-2 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
Viking lists 1-2 as a wash-motor failure reported by the motor control or a motor current out of range, depending on the model.
A Viking dishwasher showing 1-2 (one flash on Pots/Pans, two on Normal Wash) has a problem with the wash motor, which pushes water to the spray arms.
Which wording applies to your model
The same number is described two ways in the manuals.
VDB451/FDB451 and VDB325/VDB450: a motor control status error on the variable-speed motor, where the motor control reports a failure it attributes to itself.
FDB301, RDDB201, RDDB301 and VDB301: motor current out of range. This manual and the VDB200 manual both include a start capacitor among the suspects.
Your model plate tells you which one you have. Knowing the model also tells a technician which motor setup the machine uses, and the set of listed causes depends on that.
Possible causes listed
Disconnected wires from the motor control or control board to the motor.
Disconnected wires between the motor and start capacitor (capacitor-start versions).
Defective motor control or main control.
Defective motor.
Defective start capacitor.
In the VDB200 manual the technician also confirms that the rotor spins freely and measures winding resistance.
Is there anything to try?
No manual lists an owner check. Cycling the power is fine, but the motor, capacitor and wiring are in the cabinet at mains voltage. A start capacitor can store a charge, and the manual instructs technicians to discharge it before work begins.
Neighbouring codes
1-3: the main control and motor control lost their link.
3-4: the motor control reports a motor operation failure, blamed on the motor.
