My viking 450E start button is not working - the cyle buttons light up blue and then the start button should start flashing so that you can press it to start but the start button never flashes - I have...

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.

I have a viking dishwasher that is not a year old yet. I start it and within 5 min the lights start blinking on it, so it stops?

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.

Lower spray arm came off, part broken which holds it on, not sure what that part is called so we can order it... is it a spindle, bearing or axle? can't find manual for schematic thx

Hello, welcome to FixYa.

I believe the part you're referring to is called the lower spray arm bearing. It should be listed as part number 8057067-77.

This part is available at "" for around $20USD. It will include what is shown here...


The part on their site actually appears upside down so I've rotated it 180degrees as it should appear. Let me know if you have any further questions and I'll try to help in any manner I can. Good luck.

Dishwasher does not fully drain.

If the drain pipe is accessible, take it out of the trap pipe that it should be sitting in, place the open end in a bowl and lower the bowl to the floor. If you are lucky, the force of the water may bring any blockage with it. Does the water drain and was there any solids in the water? If the bowl starts getting full, simlpy raise the pipe upso that the open end is above the level in the dishwasher and the water will stop.

If no solids came out with the water, it sounds as though the pump is not running. If no water comes out at all, then you have a full blockage, usually caused by congealed fat. Take the strainer out from the inside of the dishwasher and have a look.

Come back if still not sorted.

We have this dishwasher at our firestation and have no power. We have checked the plug, and the plug is good. There are no lights, and we cannot get the machine to come on.

Hi, Welcome to FixYa. If you pull the kick plate/toe panel off you should see the junction terminals. Make sure there are no wires burnt up or loose. Let me know and we can go forward from there. Regards, Macmarkus :)

The red arrow keeps blinking and washer does not run, cycle starts then stops leaving water on bottom....


You either have a blocked drain line drain pump, or water is in the base pan. behind the toe kick is a base pan that will catch water if the flood switch is activated this condition will occur. I know this dishwasher very well can help you fix it yourself.
