What I would Do :
1st I would start your dishwasher and let it fill with water and when it stoped filling, I would open the door to see how much water it filled in the tub. ((( if you don't have enough water you will not get the correct pressure )))
If We have enough water we then close the dishwasher door and resume.
you have 2 motors in the bottom of your dishwasher, The drain pump motor and the Wash motor. They should be differen sounds.
We want to know if your wash motor is coming on.
If your wash motor is coming on then I will listen to see if I here water coming out of the spray arm. (( somtimes you can here the swish of the water hiting the door ))
If you do not here the water then I would open the door and position all spray arms the same way and close the door for a min and reopen to see if i have any movment.
If you do not have any movement and did here the motor run then your impellor might be broken or cloged or bound. you will only really find out by taking it apart. you could buy the hole pump & motor Kit. but you can save money by finding out what is the cause.
You can see a breakdown of a similar model
here
I was unable to get your model to come up and you should check the machine model number so you have it to get the correct parts. Look at the pump & motor section and you will see how this pump is broken down.
If you don't think your getting the proper water amount, just open the dishwasher door and pour 5 or 6 glasses in and close the door for the wash cycle and listen for a differance.
