Can't find the cooling fan on the wash pump motor. Having read a solution, I am trying to find the cooling fan to see if it has ceased. The machine fills and drains water but the spray arms do not turn during the cycle
More often than not when any dishwasher motor will not turn, it is the motor start capacitor at fault. It is quite rare for the main wash pump to seize.
The start cap is a cylinder about the size of a D size battery and would have 2 to 4 wires going to it.
It may look like it is melted, or maybe not. But usually will only cost you a few dollars from an appliance part store or ebay. just make sure you get the correct mF rating.

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:

Sprayers require water to pass through the jets to provide motion to the arms.
Suggestion;
Remove the sprayer from the machine and look for blockages. (Removal should be easy, at it is expected that the user will need to clean the jets occasionally; If you have any problems removing it, consult your manual).
Testimonial: "Thanks for a speedy and v helpful reply. Sounded obvious, but I hadn't checked the water inlet(which was calcified)just the jets on the arm itself! "
