Please check the door switch in the first place , remove power to the washer and check the continuity of the switch , Now trace the wires to the main panel controller check on the connections on the main panels, check all the wires leading from the main panel to the valves, pump and the motor.
Once you have made sure that the connections are correct, then check the cycle/program as the washer is switched on.
The blinking is an error and is related to a processor resetting due to its failure or an input problem.
There are no controls active on the customer pad and so no reset is possible.
Remove the power and remove the controller unit , warm up the unit to clear off any moisture. Disconnect one by one the outputs , the valve, the pump, heater and the motor.
If the blinking is relative to a short then the related removal of wire to the circuit will bring back the controller to reset.
If none of these works the possible fault can be the controller unit.

SOURCE: dishwasher viking model vdb450ss error

Hello there,

If you're certain this model number is correct, the error code indicates a "drain timeout error". This means the machine has tried and failed to pump out within a specified time limit. Please run through the following checklist to correct this problem:

1. Check and clean the filters
2. Check the drain hose isn't kinked and check for any blockages in the drain hose.
3. Make sure the hose has a high loop as per the installation instructions
4. If draining into a garbage disposal . . .

- Remove the plug from the disposal to allow air entry / eliminate any potential vacuum.
- Run water through the disposal to check for blockages

5. Ensure dishwasher is level, front to back and left to right.

When you've checked all of the above, reset the dishwasher by holding the START button for a minimum of four seconds to clear the error message.

My slight question mark over the model number is because you referred to "heavy cycle". The VDB450SS does have a heavy cycle but it's called "pot & pans" on this model. Other Viking dishwashers explicity say "Heavy" but a flashing LED above heavy on another model may indicate an entirely different fault. This is an overfill error code on some models.

If you definitely have the VDB450SS, you should be able to solve the problem using the checklist above. If you have any other model. please reply to me by clicking on "Add a Comment" below your question for further assistance. Please verify the correct model number if/when replying and whether any other LEDs are also flashing.

Hello & Welcome to FixYa

Check the door latch switch mechanism as that seems to be bad and needs replacement as everything else is working fine. Please get back to me if you have any other questions.

Detergent dispenser

Here is a link. as almost any part for anything including diagrams. The pricing on the part seems WAY out of range. Usually dispensers cost around $60.00 At least you can find the p/n and google around for it on some other sites. I can't imagine it's that much.
