Question about Dishwashers
Dishwasher would not start ...changed interlock switch...fills with water, but will not start wash cycle or drain
If I'm not mistaken, these dishwashers are built by Asko for Viking. If thats the case then you probably have a bad circulation pump. Under Asko's warranty (not sure if Viking is the same) these pumps are covered parts and labor for 3 years from installation date, and 5 years for the part only. The pump is accesed from the back of the machine,so you have to pull out the dishwasher. Then you remove the lower plate in the rear and the motor at the very back center is the pump. You remove it by turning it about a 1/4 turn either clockwise or counter clockwise, depending on the style, then place the new one in and turn it to lock it in place, being careful that the sealing oring stays in place or youll get a leak. The part will probably cost you around $150 unless viking marks theirs up more than Asko. Good Luck!

If you are still trying to sort out this issue try the following.
From what you say then it is most likely the aqua sensor on the side of the dishwasher. The gurgling sounds that you hear are likely the drain pump running and the un-drainable water sloshing in the sump.
Verify that there is actually water going to the dishwasher( Basic step but often overlooked)
Next the inlet valve will have to be checked. This is the part where the water line from the house connects to the dishwasher, under the toe/kick panel. Remove power from the dishwasher. Disconnect the dishwasher electrical connections (2 wires) to the inlet valve and connect it (carefully to 110 V power) using a jumper wire. With 110V power the valve should open and water will flow into the dishwasher, if not then the fault is in the inlet valve.
If this checks fine then the fault is likely in the aqua sensor...
On the outer left side (viewed from front) there is a panel, Behind this panel there is a small clear(of light blue) plastic mechanism with hoses and wires attached( There is usually a yellow disk at the top about 6cm in diameter) this is a float and sensor assembly there is tells the control the water level and works as an emergency drain if there is an issue. There will be a red stick protruding downward to the base and a Styrofoam float on which the stick rests. This is a pan overflow sensor if the stick is too high the unit will go into drain and cut off the fill valve power. The yellow disk is a diaphragm which senses water height. This unit can become stuck with wear and hard water.

SOURCE: Not starting wash cycle
Typically this means that there has been a water leak of some sort and there is water in the lower base pan. This is the large white plastic base that the dishwasher sits on.
If you remove the toe kick and look back past the fill valve on the extreme left side of the dishwasher about 6 to 8 inches from the front you will see a red stick that goes straight up and down. This is a mechanical linkage that activates the drain feature. Be careful as there are live connections here.
This stick rests on a round piece of Styrofoam that acts as a float. If there is water present it will cause the stick to lift and the dishwasher will go into drain. The source of the leak will have to be isolated and corrected. Most likely it is the fill float assembly as referenced at the end of this post.
If the stick is not in the upright position then there is possibly an issue with the switch mechanism itself.
You will have to pull the dishwasher out from beneath the cabinet and remove the panel covering the left hand side. If it is a full panel then there are a couple of screws holding it on from the front through side trim as viewed when the door is open if it is a half panel then it can be removed by removing the large torx screw on the lower right as seen when facing the panel.
If there is a problem with the switch then the entire mechanism should be replaced.
Try the following link to a picture for reference. It is upside down as compared to the installed one:
