It's likely that the cheap POS start switch under the button has fallen off the cheesy plastic mounting and the button isn't contacting it. Put it back so the ears on switch are under the slots in the panel and dab a TINY bit of super glue where the tabs go into the panel.

It is possible that the machine does not start off the cycle because there are errors or feedback from the inputs. For the program to start up the main program controller must initiate the INLET/PUMP MOTOR/DRAIN to work when it is commanded .If this does not happen then the voltage at these points must be checked or the fault relates to no voltage/drive from the controller. This means the controller is a suspect.

If the water flows then the flow should be good, if not the inlet valve is bad or there is dirt in the filter. Also check the flow at the inlet of the water line. What is most important for the motor to start functioning is that the door switch must be ON when the door is shut or this will be an error for starting the motor. The water pressure must be good and the spraying must be seen to be good. If there is low pumping or pressure then the spray arms will not turn around to inject with pressure. If so the pump must be checked for clogging.

To replace check this link:


Finally after the wash the drain valve will be activated, the water is allowed to come in to rinse and then finally the drain valve/pump activated so as to drain off all the water.

Make sure that a fault in any of the cycle will relate to the specified action, so check the command from the program module and then the executing device be it the valve or motor or pump.

Hello & Welcome to FixYa

John, the problem is with the door switch assembly that is bad and needs replacement, if that tests fine then replacement of control board is recommended. Please get back to me if you have any other questions.

Hello Maureen Johnson, welcome to FixYa.

I'll start by acknowledging your post indicates the problem is with your dishwasher not starting/functioning, however if you could post the complete model & serial number I would be better equipped to help you further. If you could also verify it is a Viking (built by Asko) as the header suggests.

I'll look forward to your reply and try and help you move forward from there.

Thank you. Regards,

Macmarkus :)

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.

can you please confirm which light is blinking.
Does it take in water before it stops?
Refer page 34 and 35 in this manual once you check which light is flashing.

Hope this helps.
